US 7987002

US Patent 7987002, titled "Arrangement for distributed measurement system for measurement and simulation in distributed control systems," was invented by Lars-Berno Fredriksson. The patent was filed on May 26, 2006, and issued on July 26, 2011. Its original assignee was Xinshu Management LLC, and the current assignee is Longhorn Automotive Group LLC.

The abstract describes an arrangement featuring a first unit (200, 303, 304) that processes analog and digital signals related to one or more physical measurement objects (200′, 305, 307) and their associated functions or detectors/control devices. This first unit is connected to a distributed control system (206) that operates using a first protocol (218). The first unit, compatible with the first protocol, exchanges messages with the control system and processes physical measurement/control signals. It is linked to a second connection (209) that uses a second protocol (418), forming part of a tool arrangement. The first unit communicates with a second unit (450 and/or 201, 221) via this second connection, and can be configured through connections using the first or second protocols (or their variants), allowing for separation and distribution of complex and simpler tasks across different equipment and personnel.

Here's a plain-language overview of each independent claim:

• Claim 1 (Apparatus): This claim describes a device that includes a processor communicating with an interface unit using a "first protocol." The interface unit, in turn, communicates with a distributed control system using a "second protocol." The processor's role is to create simulated measurement signals (to stand in for real sensor data) and control signals (to replace outputs from actual control devices). These simulated signals are then sent from the processor, through the interface unit, to the distributed control system, using the "second protocol" for communication with the control system and the "first protocol" for communication with the interface unit.

• Claim 15 (Monitoring System): This claim outlines a monitoring system comprising several monitoring units, categorized as "complex" and "basic." These units communicate with at least one interface unit via a "first protocol." The interface unit is connected to a distributed control system and receives data from it using a "second protocol." The complex monitoring unit receives data from the interface unit and generates programming instructions for the basic monitoring units. In response, a basic monitoring unit receives these instructions and proceeds to collect a specific part of the data from the interface unit using the "first protocol."

• Claim 25 (Method): This claim describes a method that begins with a "complex monitoring unit" receiving data from a "first distributed control system" through an interface unit. The complex unit connects to the interface unit using a "first protocol," while the interface unit connects to the control system using a "second protocol." The complex unit then analyzes the received data to identify a specific subset of data values. Based on this analysis, the complex unit generates programming instructions. These instructions are designed to enable a "basic monitoring unit" to collect a corresponding subset of data when it is connected to a "second distributed control system" that has a similar architectural setup.

A search of the CAFC 2026 dockets for patent number US7987002 did not return any results as of April 26, 2026. Therefore, no active cases related to this specific patent were found in the Federal Circuit dockets for 2026.US Patent 7987002, titled "Arrangement for distributed measurement system for measurement and simulation in distributed control systems," was invented by Lars-Berno Fredriksson.

• Claim 1 (Apparatus): This claim describes a device that includes a processor communicating with an interface unit through a data connection using a "first protocol." The interface unit, in turn, communicates with a distributed control system using a "second protocol." The processor is configured to provide simulated measurement signals (intended to replace real sensor input) and control signals (intended to replace signals from actual control devices). These simulated measurement signals and control signals are sent from the processor to the distributed control system via the interface unit, utilizing the "second protocol" for communication with the control system and the "first protocol" for communication with the interface unit.

• Claim 15 (Monitoring System): This claim outlines a monitoring system comprising a plurality of monitoring units, which include at least one complex monitoring unit and at least one basic monitoring unit. These units communicate with at least one interface unit using a "first protocol." The interface unit is connected to a distributed control system and is configured to receive data values from it using a "second protocol." The complex monitoring unit receives data from the interface unit using the "first protocol" and generates programmatic instructions for the basic monitoring unit. The basic monitoring unit then receives these instructions and, in response, collects a subset of the data values from the interface unit using the "first protocol".

• Claim 25 (Method): This claim describes a method that begins with a "complex monitoring unit" receiving data values from a "first distributed control system." This is achieved by connecting the complex monitoring unit via a "first data connection" using a "first protocol" to an interface unit, which itself is connected to the first distributed control system and communicates with it using a "second protocol" through a "second data connection." The complex monitoring unit then analyzes the received data values to identify a specific subset of these values. Finally, the complex monitoring unit generates programmatic instructions designed to cause a "basic monitoring unit" (when running these instructions) to collect a corresponding subset of data values after connecting to a "second distributed control system" with similar architecture.

Proceedings overview

There are no AIA trial proceedings on file for US Patent 7987002 as of the most recent ingest from the USPTO ODP API. A web search did not surface any additional PTAB proceedings. This means that all claims of the patent remain untested in an AIA trial context, and a defendant currently facing assertion of this patent would approach it with the understanding that its validity has not been challenged before the PTAB.

Strategic summary

As of the current date, US Patent 7987002 has no record of AIA trial proceedings at the PTAB. This implies that all claims (1-29) of the patent are currently UNTESTED through inter partes review (IPR), post-grant review (PGR), or covered business method (CBM) proceedings.

The absence of PTAB challenges for a patent that has been in force since 2011 is noteworthy, especially given its "Active" legal status and identified litigation in various District Courts. Typically, patents asserted in litigation, particularly those involved in multiple cases, often become targets for AIA trial petitions. This lack of PTAB activity could mean several things: either potential petitioners have not found strong prior art that meets the institution threshold, or the patent's claims are considered robust against IPR/PGR challenges, or the asserted claims are not considered significant enough to warrant a PTAB challenge, or the patent has not yet been asserted in a context that typically draws PTAB filings (e.g., against large tech companies).

For a defendant currently being asserted against, the entire landscape of prior-art grounds is still available. There are no estoppel bars under § 315(e)(2) from previous PTAB proceedings. Therefore, any prior art grounds (e.g., under § 102 or § 103) that could be raised in an IPR are still viable for a new petition. The litigation history, particularly the filings in the Texas Eastern District Court, suggests active assertion, which might eventually lead to PTAB challenges if defendants decide to pursue that route.

Recommended next steps

Given the absence of any PTAB activity for US Patent 7987002:

• For a potential defendant: Consider a comprehensive prior art search to evaluate the strength of a potential IPR or PGR petition against the asserted claims. The absence of previous challenges means there is no existing PTAB record to leverage, making the initial prior art investigation and petition drafting critical.
• Monitor for future filings: Stay vigilant for any new IPR, PGR, or CBM petitions filed against US7987002, as the patent's active litigation status might change this landscape in the future.
• The absence of PTAB activity itself is a signal: well-asserted patents eventually attract IPRs. The fact that this patent, which has litigation history, has not yet faced a PTAB challenge suggests that potential challengers either have not found compelling grounds or have chosen alternative litigation strategies.

Proceedings overview

The USPTO ODP API reports no AIA trial proceedings (Inter Partes Review, Post-Grant Review, or Covered Business Method) on file for US Patent 7987002. However, web search has identified one ex parte reexamination proceeding concerning this patent. While an ex parte reexamination is distinct from an AIA trial, its institution indicates that "substantial new questions of patentability" have been found for the challenged claims. This means the patent's claims are currently under re-evaluation at the USPTO.

Ex Parte Reexamination Control No. 90/019,867 — Unified Patents v. Longhorn Automotive Group LLC

• Type: Ex Parte Reexamination (Note: This is not an AIA trial proceeding like IPR, PGR, or CBM, but an administrative reexamination by the USPTO.)
• Filed: 2025-02-26
• Status: Institution Granted (Central Reexamination Unit granted Unified Patents' request on 2025-04-22, finding substantial new questions of patentability on the challenged claims.)
• Judge panel: N/A (Ex parte reexaminations are conducted by a USPTO examiner, not a PTAB judge panel).
• Petition grounds: Unified Patents filed the reexamination request. The specific claims challenged are not explicitly listed in the public summary, but the CRU found "substantial new questions of patentability" on "the challenged claims." Prior art identified by Unified Patents that led to "winning prior art" on this patent includes US 20080040477, US 6324607, US 6529589, and WO 2002013036. The statutory basis is typically anticipation (§ 102) and/or obviousness (§ 103) based on prior art.
• Institution decision: Instituted on 2025-04-22. The Central Reexamination Unit (CRU) granted Unified Patents' request, determining that there are "substantial new questions of patentability" on the challenged claims of the patent.
• Final Written Decision (if issued): Not yet issued, as the reexamination was recently instituted.
• Settlement / termination: N/A (This is a USPTO-initiated proceeding, not a party-negotiated settlement).
• Appeal: Not yet applicable. Decisions in ex parte reexamination can be appealed to the PTAB and then to the Federal Circuit, but only after a final decision by the examiner.
• Defensive value: The institution of this ex parte reexamination is a significant development. A finding of "substantial new questions of patentability" means the USPTO examiner believes there's a good chance the challenged claims may be invalid over the cited prior art. This places a cloud over the validity of those claims and could significantly impact ongoing or future infringement assertions. While not an AIA trial, it serves as a strong signal of potential invalidity.

Strategic summary

While there are no AIA trial proceedings (IPR, PGR, CBM) on file for US Patent 7987002, an ex parte reexamination (Control No. 90/019,867) was filed by Unified Patents on 2025-02-26 and subsequently instituted on 2025-04-22. The institution indicates that the Central Reexamination Unit found "substantial new questions of patentability" regarding the challenged claims. This means the validity of some claims, although not specified in the public summaries, is now officially under review by a USPTO examiner.

Currently, all claims of US7987002 remain untested in the context of AIA trial proceedings. However, the ex parte reexamination directly challenges the patent's validity. If the reexamination ultimately results in cancellation of claims, those claims will be CANCELED. If claims are confirmed, they will be SUSTAINED (though potentially with amendments). The claims not addressed in the reexamination would remain UNTESTED.

The estoppel landscape differs for ex parte reexamination compared to AIA trials. A third-party requestor in an ex parte reexamination is generally not subject to the same estoppel provisions as petitioners in IPRs/PGRs. This means that if a defendant is being asserted against, even if Unified Patents challenged certain claims, that defendant might still be able to raise similar or different prior-art grounds in district court litigation or a new IPR (if eligible), provided they are not a privy to Unified Patents or have not previously raised and lost on those grounds in a different forum.

Unified Patents, a defensive aggregator, initiated this reexamination. Their involvement signals a concerted effort by the industry to challenge patents asserted by Non-Practicing Entities (NPEs) like Longhorn Automotive Group LLC. The patent is currently being asserted against several major automotive companies, including Volkswagen, Mazda, Hyundai, Mitsubishi, Volvo, and Nissan.

Recommended next steps

• For a defendant facing assertion of US7987002: Immediately investigate the specifics of Ex Parte Reexamination Control No. 90/019,867. Access the reexamination request and institution decision through the USPTO's public PAIR system or Unified Patents' portal (https://portal.unifiedpatents.com/exparte/90019867) to identify precisely which claims are challenged and what prior art is being used.
• Monitor the reexamination: Track the progress of the ex parte reexamination closely. Any office actions, responses, or examiner's determinations could provide valuable insights into the patent's validity.
• Evaluate impact on ongoing litigation: The finding of "substantial new questions of patentability" could be used in district court litigation to argue for a stay of proceedings or to challenge the validity of the asserted claims.
• Consider further action: Depending on the outcome of the reexamination, and the specific claims being asserted, a defendant might still consider filing an IPR or PGR (if statutory requirements are met) for any claims not covered by the reexamination or if new prior art is discovered.

Inventors

The named inventor on US Patent 7987002 is Lars-Berno Fredriksson. At the time of filing (2006-05-26), Fredriksson assigned his interest to Kvaser Consultant AB on 2006-06-05. This suggests Kvaser Consultant AB was likely his employer or an entity with which he was closely associated. Kirk M. McInerney is listed as an assignor in 2009 for the same patent family, indicating he is also an inventor on a related application, but his employer is not specified in the patent text.

Original assignee

The entity named as the original assignee on the issued patent is Xinshu Management, L.L.C. While the inventor Lars-Berno Fredriksson initially assigned his rights to Kvaser Consultant AB, Kvaser subsequently changed its name to Timegalactic AB, which then assigned the patent rights to Xinshu Management, L.L.C. before the patent was granted.

Xinshu Management, L.L.C. does not appear to have shipped products embodying the claims of the patent. Its name, "Management, L.L.C.," and the fact that it acted as its own correspondent for an assignment record, suggest it functioned as a patent holding or licensing entity. Xinshu Management, L.L.C. was later merged into Callahan Cellular L.L.C. in 2015.

Verdict

NPE — high confidence

The patent chain for US7987002 exhibits multiple strong signals indicative of non-practicing entity (NPE) behavior. These include the presence of a known asserter (Intellectual Ventures Assets 190 LLC on Reel 053526/0424 and the current owner Longhorn Automotive Group LLC), a series of shell-entity transfers, cascading transfers (Reel 053738/0558 and Reel 054653/0256 occurring within five months), and a pre-litigation transfer to Longhorn Automotive Group LLC (executed 2024-03-26) preceding multiple infringement lawsuits filed in 2024. The recurring correspondent, William S. McElwee, for the recent NPE-related transfers further strengthens this conclusion.

Verification: USPTO Assignment Center search for US7987002.

To identify the most relevant prior art for US Patent 7,987,002, I will search the USPTO patent citations for this specific patent.

As of April 26, 2026, the Central Reexamination Unit (CRU) has already granted Unified Patents' request for ex parte reexamination of US Patent 7,987,002, finding substantial new questions of patentability on the challenged claims. This indicates that prior art has been identified and deemed significant enough to warrant reexamination. Unified Patents has also previously announced that prior art was found on this patent. While the full list of prior art references considered in the reexamination is not directly available in the search snippets, the fact that a reexamination was instituted points to the existence of relevant prior art impacting the claims.

The provided information also mentions ongoing contests by Unified Patents to find prior art for US Patent 7,987,002, specifically seeking prior art on at least claim 15. This suggests that prior art relevant to claim 15, and potentially other claims, is still being actively sought or evaluated.

Without direct access to the full prosecution history or the specific prior art documents cited by the USPTO in the reexamination or submitted by Unified Patents, I cannot provide a definitive list of all the most relevant prior art. However, the initiation of the ex parte reexamination (Control No. 90/019,867) confirms that relevant prior art has been brought to the attention of the USPTO and is being formally evaluated against the patent's claims.

To obtain the specific prior art citations and their details, one would typically need to access the public records of the ex parte reexamination proceeding for US Patent 7,987,002 (Control No. 90/019,867) through the USPTO's Patent Center or Public PAIR system. These systems provide access to the complete file wrapper, including all cited prior art during examination and reexamination.

Obviousness Analysis of US Patent 7987002 Under 35 U.S.C. § 103

This analysis identifies combinations of prior art references that would render the claims of US Patent 7987002 obvious to a person having ordinary skill in the art (POSITA) as of the patent's priority date of November 26, 2003. A POSITA in this field would typically be an engineer or technician with experience in distributed control systems, embedded systems, communication protocols (e.g., CAN, USB, Bluetooth), and measurement/calibration tools for automotive or industrial applications.

The patent itself identifies International Application PCT/SE2003/01219, published as WO 2004/015945 A1 (priority date July 16, 2003), as "previous work" and states that US7987002 "can be considered to be a further development of that previous work." This makes WO 2004/015945 A1 a primary and highly relevant piece of prior art.

Combination 1: WO 2004/015945 A1 in view of known Hardware-in-the-Loop (HIL) Simulation Techniques and the common practice of distributing tasks between computing devices (e.g., PC and PDA).

Rationale for Combination 1:

WO 2004/015945 A1, as the inventor's own "previous work" on which US7987002 is a "further development," is highly likely to disclose the core architecture described in US7987002's summary. This core includes:

• A first unit (e.g., an interface unit or measurement module) connected to a distributed control system operating with a first protocol (e.g., CAN).
• This first unit obtains and/or provides information compatible with the first protocol.
• The first unit includes inputs for analog/digital measurement signals and outputs for analog/digital output signals.
• The first unit transforms information from the first protocol to a second protocol for a tool arrangement (e.g., a PC or PDA).
• The tool arrangement works with the second protocol, enabling readings and/or changes in the first protocol to be implemented via the second protocol.

Obviousness of Claim 1 (Apparatus)

Claim 1 focuses on a processor device providing simulated measurement signals and control signals to the distributed control system via an interface unit for simulation purposes.

1. Processor device communicating with an interface unit using a first protocol, and the interface unit communicating with a distributed control system using a second protocol: This fundamental architecture is understood to be disclosed by WO 2004/015945 A1, which describes a multi-protocol communication system for measurement and control within distributed control systems.
2. Processor device configured to provide simulated measurement signals and control signals to replace actual input data and control signals in the distributed control system: By the priority date of November 2003, Hardware-in-the-Loop (HIL) simulation was a well-established technique for testing electronic control units (ECUs) and distributed control systems, especially in automotive and industrial contexts. HIL systems precisely involve a processor (often part of a testbed) generating simulated sensor inputs and receiving control outputs, which are then fed back as simulated environmental conditions. "2003: DISTRIBUTED SIMULATION SYSTEMS" confirms that the integration of various simulators into a single, distributed simulation environment was an important motivation by 2003. A POSITA would have been motivated to integrate HIL simulation capabilities into the measurement and analysis system described in WO 2004/015945 A1 to enable comprehensive and repeatable testing and validation of the distributed control system in a controlled environment.
3. Sending simulated signals using the second protocol via the interface unit and the first protocol: This is the logical application of the HIL simulation concept within the existing multi-protocol architecture taught by WO 2004/015945 A1. The simulated signals would simply follow the established communication paths to interact with the distributed control system.

Obviousness of Claim 15 (Monitoring System) and Claim 25 (Method)

Claims 15 and 25 introduce the concept of a plurality of monitoring units, including at least one "complex monitoring unit" (e.g., a PC) and at least one "basic monitoring unit" (e.g., a PDA), where the complex unit generates programmatic instructions for the basic unit to collect a subset of data.

1. Monitoring units communicating with an interface unit using a first protocol, connected to a distributed control system receiving data via a second protocol: As with Claim 1, this underlying system architecture is disclosed by WO 2004/015945 A1.
2. Plurality of monitoring units comprising complex and basic monitoring units: US7987002 itself explicitly describes the varying capabilities of a PC (complex) versus a PDA (basic) and the expediency of allocating processor-intensive tasks to the PC and reducing the tool's capacity for a PDA version.
3. Complex monitoring unit generating programmatic instructions for the basic monitoring unit, and the basic unit receiving/executing them to collect a subset of data: The patent further explains that the PC version can be used as a "programming tool" for the PDA version, where "After it has been determined in the PC which tasks are to be resolved and how the results are to be displayed, a configuration file is generated which is then downloaded to the PDA." This directly describes a complex unit (PC) creating configuration or programmatic instructions that a basic unit (PDA) would then execute to collect specific data. A POSITA would be motivated to adopt such an approach to leverage the strengths of both device types: the PC for sophisticated analysis and configuration, and the PDA for portable, streamlined, and pre-configured data collection and diagnostics in the field. This improves efficiency and practical utility for technicians.

Obviousness of Specific Protocol-Related Features

• CAN Calibration Protocol (CCP) (Claim 6): The use of CCP for requesting measurement signals is explicitly mentioned in the patent. CCP 2.1 was released in February 1999, well before the priority date. It was a known standard for calibration and data acquisition from ECUs in CAN-based systems, enabling read/write access to ECU memory and synchronous/event-driven data acquisition. Therefore, a POSITA designing a measurement system for a CAN-based distributed control system would find it obvious to use CCP for requesting measurement signals.
• Other Protocols (Claims 3, 4, 5, 13, 14): The patent references standard protocols like USB, Bluetooth, PCMCIA, TCP/IP, J1939, TTCAN, and CanKingdom. These were widely known and used in their respective domains by 2003. For instance, USB and PCMCIA were standard for connecting PC peripherals, and Bluetooth was known for short-range wireless communication, often using USB or UART as underlying transport layers. US 2003/0050009 A1 also discusses Bluetooth for secure data exchange and pairing. The choice of such known protocols for the communication links would have been an obvious engineering choice for a POSITA, depending on the specific application requirements.

In conclusion, the combination of WO 2004/015945 A1 (for the foundational system architecture) with the well-known principles of HIL simulation and the established practice of distributing complex and simpler tasks between computing devices like PCs and PDAs would render the claims of US7987002 obvious to a person having ordinary skill in the art by November 26, 2003. The specific protocol choices further represent obvious implementations of known technologies.

US Patent 7987002 was filed on May 26, 2006, and issued on July 26, 2011. The patent claims priority to Swedish Application 0303138-2, filed on November 26, 2003, and is a continuation of International Application PCT/SE04/001540, filed on October 25, 2004. PCT/SE04/001540 also claims priority to Swedish Application 0303138-2. Additionally, US7987002 is related to International Application PCT/SE2003/01219, filed on July 16, 2003, and published as WO 2004/015945 A1.

Based on the general rule for utility patents filed on or after June 8, 1995, the patent term is 20 years from the earliest filing date for which a benefit is claimed under 35 U.S.C. 120, 121, or 365(c). In this case, the earliest priority date is November 26, 2003, from Swedish Application 0303138-2. Therefore, the statutory 20-year term would typically end on November 26, 2023.

However, the patent's legal status indicates that it is "Active" and "expires 2027-08-26." This adjusted expiration date suggests that Patent Term Adjustment (PTA) has been granted. PTA compensates for administrative delays incurred during prosecution before the USPTO.

It also provides "control signals" in the form of precisely shaped microwave or laser pulses, which replace actual quantum gate operations. The interface unit translates these classical control signals into their physical equivalents (e.g., analog voltage waveforms for microwave generators) and receives quantum measurement outcomes (e.g., photon counts, dispersive readout signals). The "distributed control system" is a quantum chip operating at millikelvin temperatures, using a custom low-level pulse sequence protocol as its "second protocol." The "first protocol" between the quantum-classical hybrid controller and the interface unit is a high-speed, low-latency interconnect (e.g., an optical link with picosecond timing resolution) designed to handle the stringent real-time demands of quantum experiments.

Based on these predictions, it issues "control signals" to simulate proactive maintenance actions, such as reducing the operational speed of a specific robot or scheduling a component replacement. The interface unit gathers real-time data from IoT sensors (e.g., vibration accelerometers, thermistors) integrated into the machinery, communicating with the processor device via an MQTT (Message Queuing Telemetry Transport) first protocol. The interface unit then interacts with the industrial distributed control system, comprising PLCs and robotic controllers, using a PROFINET second protocol.

The processor device generates "simulated measurement signals" representing potential supply chain disruptions, such as a simulated factory delay or a quality control failure at a distribution hub. These events, along with simulated outcomes, are broadcast to the blockchain. "Control signals" are then simulated to test mitigation strategies, such as re-routing shipments or engaging alternative suppliers, with their effects timestamped and hashed onto the distributed ledger. The interface unit, a secure enterprise gateway, communicates with the processor device via a RESTful API over HTTPS (first protocol), interfacing with the blockchain. It then communicates with the distributed control system, representing various supply chain nodes (e.g., warehouse management systems, transportation logistics platforms), using an AMQP (Advanced Message Queuing Protocol) second protocol for reliable message exchange.

5. The "Inverse" or Failure Mode

• Derivative 1.9: Safe Shutdown Simulation with Degrading Components

  • Enabling Description: This apparatus is designed to simulate the safe and controlled shutdown of a critical distributed control system (e.g., a chemical processing plant) under conditions of progressive component degradation. The processor device injects "simulated measurement signals" into the system, indicating worsening sensor drift, increased actuator response latency, and intermittent network packet loss. It then generates "control signals" to activate pre-defined emergency shutdown sequences, such as gradual valve closures, pump deactivation, and power-down procedures, aiming to bring the plant to a stable, low-energy state while minimizing damage. The interface unit is a safety-rated PLC, communicating with the processor device via a PROFIsafe (first protocol) link, ensuring functional safety and data integrity. This interface unit, in turn, interacts with the plant's distributed control system, which includes safety instrumented systems (SIS), using a redundant, fail-safe industrial Ethernet (e.g., EtherNet/IP with CIP Safety) as its second protocol.

• Derivative 1.10: Limited Functionality Mode Simulation for Resource Conservation

  • Enabling Description: The apparatus simulates a smart home distributed control system operating in a "limited functionality mode" due to a prolonged power outage or low battery reserves from a solar power system. The processor device generates "simulated measurement signals" indicating critically low battery voltage or a degraded external power grid status. It then provides "control signals" to automatically deactivate non-essential smart home functions (e.g., dimming lights, disabling entertainment systems, reducing HVAC fan speed, prioritizing critical security sensors). The interface unit, an energy management gateway, communicates with the processor device using a Bluetooth Low Energy (BLE) first protocol, optimizing data transfer for minimal energy consumption. The interface unit then controls the various smart home devices (lighting, thermostats, sensors) within the distributed control system using a Zigbee (IEEE 802.15.4) second protocol, which is also inherently low-power.

The first protocol between the basic monitoring units and the interface unit is a Zigbee mesh network (IEEE 802.15.4), while the second protocol between the interface unit and the distributed control system (e.g., a remote climate control system) is a proprietary industrial Ethernet. The complex unit generates programmatic instructions (e.g., sampling frequency adjustments, threshold alerts) for the basic SoCs, transmitted via the satellite link and interface units.

The first protocol between the basic units and the interface unit is a proprietary sub-GHz RF protocol optimized for burst communication and ultra-low power consumption. The complex monitoring unit, located centrally, generates programmatic instructions for these basic units, defining data logging triggers (e.g., log if vibration exceeds 5g) and transmission schedules. The interface unit receives the burst data and relays it to the complex unit. The distributed control system (e.g., a SCADA system) uses a standard Modbus TCP protocol.

Basic monitoring units, encased in high-pressure titanium shells (rated for 6000 meters depth), continuously collect data values such as salinity, temperature, pressure, and dissolved oxygen at 0-4°C. The first protocol for communication between these basic units and an underwater interface unit is an acoustic modem link (e.g., using frequency-shift keying at 10-20 kHz) due to the attenuation of electromagnetic waves in water. The complex monitoring unit, on a research vessel, processes the acoustic data, identifying anomalous readings or long-term trends. It generates programmatic instructions (e.g., change sampling rate, enable specific sensors) which are transmitted acoustically to the basic units via the interface unit.

• Derivative 15.4: High-Frequency Financial Market Surveillance

  • Enabling Description: The monitoring system is tailored for high-frequency financial market surveillance. Basic monitoring units are FPGA-based network tap devices strategically placed at data centers, capturing raw market data feeds (e.g., FIX protocol, native exchange binary protocols) at nanosecond timestamp resolution. These FPGAs are programmed to identify specific patterns (e.g., large order book changes, latency arbitrage attempts) and collect a subset of data values related to these events. The complex monitoring unit is a dedicated high-performance server with GPU accelerators, processing aggregated event data and running machine learning models for real-time anomaly detection. The first protocol between the FPGA basic units and the server-based complex unit is a low-latency 100 Gigabit Ethernet link with RDMA (Remote Direct Memory Access) for direct memory transfers. The second protocol, used by the interface unit (a low-latency network switch) to receive market data, is the exchange's proprietary binary protocol.

  • Enabling Description: This monitoring system is applied to wildlife tracking and behavioral analysis. Basic monitoring units are miniaturized GPS/accelerometer tags (e.g., using Nordic Semiconductor nRF52 series SoCs) attached to animals. These tags collect data values such as GPS coordinates, speed, and activity levels. The complex monitoring unit is a cloud-based analytics platform that receives data from multiple interface units (e.g., cellular base stations, satellite ground stations) via LoRaWAN (first protocol) or Argos satellite system. The complex unit generates programmatic instructions (e.g., adjust GPS logging frequency based on observed activity, trigger data transmission on geofence entry) for the basic units, optimizing battery life and data relevance. The interface unit receives raw sensor data from the basic units and relays it. The distributed control system comprises a network of automated feeding stations or camera traps, which can be managed via a separate control channel.

• Derivative 15.6: Structural Health Monitoring of Bridges/Buildings

  • Enabling Description: The monitoring system is configured for structural health monitoring of large civil engineering structures (e.g., suspension bridges, high-rise buildings). Basic monitoring units are ruggedized wireless sensor nodes (e.g., Imote2-based) embedded within the structure, containing arrays of strain gauges, accelerometers, and acoustic emission sensors. These units collect data values on structural deformation, vibration, and crack propagation. The complex monitoring unit, a central structural engineering analysis server, processes this data, performs finite element analysis, and detects anomalies. It generates programmatic instructions (e.g., increase sampling rate during high wind events, activate specific sensor groups) for the basic units, transmitted via a robust IEEE 802.15.4 wireless mesh network (first protocol) with routing protocols like RPL (Routing Protocol for Low-Power and Lossy Networks). The interface units are mesh network gateways.

4. Integration with Emerging Tech

• Derivative 15.7: IoT-Enabled Smart Grid Monitoring with Edge Analytics

  • Enabling Description: This monitoring system is integrated into a smart electrical grid infrastructure. Basic monitoring units are IoT-enabled smart meters and substation monitors, collecting real-time data values such as voltage, current, power factor, and harmonic distortion. The complex monitoring unit, a utility-scale cloud platform, analyzes this vast dataset and generates programmatic instructions for edge analytics algorithms (e.g., non-intrusive load monitoring, fault localization, predictive maintenance for transformers) to be executed directly on the basic units. This significantly reduces data transmission latency and bandwidth. The first protocol between the basic units and the interface unit (a local data concentrator) is a secure CoAP/DTLS over UDP for constrained IoT devices. The second protocol, used by the interface unit to communicate with the existing SCADA (Supervisory Control and Data Acquisition) distributed control system, is DNP3 (Distributed Network Protocol 3) over TCP/IP.

• Derivative 15.8: Federated Learning for Anomaly Detection in Manufacturing

  • Enabling Description: The monitoring system applies federated learning for anomaly detection in a distributed manufacturing plant. Each basic monitoring unit, embedded in a CNC machine or robotic arm, collects local operational data (e.g., motor current, spindle speed, tool wear). It trains a local machine learning model (e.g., a small neural network) to identify anomalies specific to its machine. The complex monitoring unit, a central server, orchestrates the federated learning process, receiving only model updates (gradients or weights), not raw data, from multiple basic units via gRPC (Google Remote Procedure Call) as the first protocol. The complex unit aggregates these updates to create an improved global model. This global model is then distributed as programmatic instructions back to the basic units to enhance their local anomaly detection capabilities. The interface units are industrial gateways. The distributed control system, consisting of the factory's PLCs and machine controllers, uses OPC UA for data exchange with the interface units.

5. The "Inverse" or Failure Mode

• Derivative 15.9: Black Box Event Recorder for System Failure Diagnostics

  • Enabling Description: The monitoring system acts as a "black box" for complex autonomous systems (e.g., autonomous vehicles, industrial robots) to diagnose critical failures. Basic monitoring units are crash-hardened, self-contained data logging modules within the autonomous system, continuously recording data values such as sensor inputs, control commands, system state, and internal diagnostics to a high-endurance, non-volatile MRAM (Magnetoresistive RAM). Upon detection of a severe anomaly or crash event (e.g., sudden deceleration, power loss), programmatic instructions, pre-programmed or issued by a complex unit (e.g., a supervisory safety controller), trigger a final data snapshot and seal the memory to prevent tampering. The first protocol for periodic data offload or instruction updates is a redundant ARINC 429 bus (for aviation/automotive). The interface unit manages this bus. The second protocol for internal system communication is the vehicle's standard automotive Ethernet.

• Derivative 15.10: Environmental Data Collection in Power-Down Mode

  • Enabling Description: The monitoring system is designed for long-term environmental data collection in remote areas where the primary distributed control system (e.g., a scientific instrument array) is mostly in a power-down or standby state. Basic monitoring units employ ultra-low-power microcontrollers (e.g., consuming nano-amperes in sleep mode) and wake-up timers, configured to sample data values (e.g., temperature, barometric pressure, UV index) at highly infrequent intervals (e.g., once an hour, once a day). The complex monitoring unit, a research station server, generates programmatic instructions defining these sleep/wake cycles, sensor configurations, and data logging thresholds, optimizing for years of battery life. The first protocol is NB-IoT (Narrowband IoT) for intermittent, burst-mode transmission of small data packets from the basic units to an NB-IoT base station (interface unit). The second protocol is a simple GPIO or I2C bus for direct sensor reading when the primary scientific instrument is active.

The connection between the complex unit and the interface unit (e.g., a Quantum Key Distribution-enabled network switch) uses a first data connection secured by Quantum Key Distribution (QKD) protocols (e.g., BB84 or E91), ensuring provable eavesdropping detection for the symmetric keys used for subsequent data encryption. The FPGA-based complex monitoring unit, utilizing reconfigurable logic, performs hardware-accelerated analysis of network traffic (e.g., detecting specific packet sequences, protocol anomalies from the second protocol like PROFINET over encrypted Ethernet). It identifies a subset of critical diagnostic data values. Programmatic instructions, including custom FPGA bitstreams for specific monitoring tasks and QKD parameters, are then generated. These instructions cause a basic monitoring unit (e.g., a field-programmable SoC) to connect to a second distributed control system (similar PROFINET architecture) and securely collect a corresponding subset of diagnostic data, using QKD for its communication as well.

The first data connection uses a flexible, low-power SPI bus embedded within the stretchable electronics, while the second data connection (between the patch and individual sensors) uses a proprietary low-power wired interface. The complex monitoring unit analyzes these biometric data values to identify a subset indicating early signs of stress or fatigue. Programmatic instructions are generated, configuring a basic monitoring unit (another stretchable patch with similar sensors) to collect a corresponding subset of data values from a second patient's biometric network (similar architecture), specifically targeting the identified stress/fatigue indicators, and potentially triggering haptic feedback on the patch.

Combination Prior Art Scenarios

Here are three combination prior art scenarios where US Patent 7987002 is combined with existing open-source standards, demonstrating how its concepts could be rendered obvious or non-novel in light of readily available technologies.

1. US7987002 (Claim 1) + OPC UA (Open Platform Communications Unified Architecture)

   • Combination: The core concept of Claim 1 involves a processor device communicating with an interface unit using a "first protocol" and that interface unit communicating with a distributed control system using a "second protocol" for simulation and control. OPC UA is an open-source, platform-independent, service-oriented architecture that defines secure, reliable, and interoperable communication for industrial automation. It supports data modeling, discovery, methods, and alarms.
   • Scenario Description: A practitioner skilled in the art, seeking to implement the apparatus of Claim 1, would readily consider using OPC UA as the "first protocol" between the processor device (e.g., a PC running a simulation engine) and the interface unit. The interface unit, acting as an OPC UA server, would expose the capabilities for providing simulated measurement signals and control signals as OPC UA nodes. The "second protocol" connecting the interface unit to the distributed control system (e.g., a factory floor with CAN-based PLCs) could then be a CAN-to-OPC UA gateway. The simulation engine on the PC would write simulated values to OPC UA nodes representing physical inputs, and read from OPC UA nodes representing control outputs, which the interface unit (OPC UA server) would then translate to/from the CAN bus. OPC UA's inherent information modeling and time synchronization capabilities (e.g., via network time protocols) would naturally extend the patent's teaching regarding structured information and temporal correlation.

       A -- Write Control Signals (OPC UA Node) --> B
       B -- Read Simulated Measurement Signals from DCS (OPC UA Node) --> A
       B -- Read Control Signals from DCS (OPC UA Node) --> A
   

2. US7987002 (Claim 15) + ROS (Robot Operating System)

   • Combination: Claim 15 describes a monitoring system with complex and basic monitoring units, an interface unit, and protocols for communication, with the complex unit generating programmatic instructions for the basic units. ROS is an open-source, flexible framework for writing robot software, providing tools, libraries, and conventions for distributed computing, inter-process communication, and hardware abstraction.
   • Scenario Description: An engineer developing a diagnostic system for a fleet of robots (the distributed control system) would consider leveraging ROS. The "complex monitoring unit" could be a ROS master or a powerful workstation running ROS, allowing visualization and analysis of robot states using ROS tools (e.g., RViz, rqt). The "interface unit" would be a standard computer or embedded system running ROS, acting as a bridge to the physical robot's internal network (e.g., EtherCAT for motor control, which would be the "second protocol"). The "basic monitoring units" would be embedded microcontrollers (e.g., ARM-based with ROS-compatible libraries like ROS-Embedded) on individual robots. The "first protocol" between the complex/basic units and the interface unit would be ROS messages over TCP/IP or DDS. The complex monitoring unit would analyze ROS topics (data values from robots) and generate "programmatic instructions" in the form of ROS launch files, Python scripts, or new robot behaviors, which are then transmitted to the basic units (e.g., via roslaunch or rosrun commands over the network) to collect specific robot performance data subsets or simulate sensor failures. The modularity and distributed nature of ROS naturally support the hierarchical and distributed aspects of Claim 15.

3. US7987002 (Claim 25) + Apache Kafka

   • Combination: Claim 25 describes a method involving a complex monitoring unit receiving data, analyzing it, and generating programmatic instructions for a basic unit to collect a subset of data from a similar system. Apache Kafka is an open-source distributed streaming platform capable of handling trillions of events a day, widely used for building real-time data pipelines and streaming applications.
   • Scenario Description: For a large-scale data collection and analysis pipeline (e.g., monitoring server clusters), a software engineer would leverage Apache Kafka. The "first distributed control system" is a server farm generating log data and metrics, streaming them into Kafka topics via Kafka Producers (which also function as the "interface unit"). The "second protocol" for generating these logs could be standard network protocols (e.g., syslog over UDP, metrics via Prometheus exporters). The "complex monitoring unit" is a powerful analytics server acting as a Kafka Consumer, receiving raw "data values" (log entries, metrics) from the first distributed control system via Kafka's native protocol (the "first data connection" and "first protocol"). This unit analyzes the Kafka streams to identify a "subset of data values" indicating, for instance, specific error patterns or performance bottlenecks. It then generates "programmatic instructions" (e.g., new Kafka consumer configurations, stream processing rules using Kafka Streams API) for a "basic monitoring unit" (another Kafka Consumer/Producer). This basic unit is configured to connect to a "second distributed control system" (a similar server farm also streaming to Kafka) and efficiently collect a "corresponding subset of data values," enabling targeted monitoring and diagnostics across similar infrastructures.
