thought
The user is asking for an obviousness analysis of US patent 11128710 under 35 U.S.C. § 103, based on the provided prior art.
I need to identify combinations of these prior art references that would make the claims of US11128710 obvious to a person having ordinary skill in the art (POSITA) and explain the motivation for such combinations.

I will focus on the independent claims (Claim 1, Claim 13, and Claim 14) as they define the scope of the invention.

Here's a breakdown of the steps:

1. Understand the independent claims of US11128710:

   • Claim 1: Control system with a control server, field units (sensors), actuator units, router, and Internet communication.
   • Claim 13: Method for controlling an environment using a remote control server, field units (sensors), control logic, actuator commands, Internet, and local router.
   • Claim 14: Similar to Claim 1, but specifically includes an image sensor, image data processing (motion sensing, face detection/recognition), and control logic based on this processing.

2. Review the provided prior art definitions and references:

   • FIG. 1 and associated text: Describes a prior art arrangement 10 in a residence 19 with a gateway 11 connecting various internal networks (sensor network 12, home networks 14a, 14b) to the Internet 16 and a server 17. Sensor network 12 can use ZigBee. Gateway 11 is a dedicated hardware device, sometimes called Residential Gateway (RG) or Home Gateway, and includes a broadband modem, firewall, router, packet-switch, and WAP.
   • Suzuki and Inoue (2011) "Home Network with Cloud Computing for Home Management": Describes a prior-art architecture involving moving limited management functions of a home gateway onto a network cloud.
   • U.S. Pat. No. 6,243,571 to Bullock et al.: Describes a powerline communication system.
   • General definitions: Server, client, Internet, TCP/IP, WMN, WDS, SaaS, Cloud Computing, ZigBee, Z-Wave, FDM, PLC, POTS, WLAN, IEEE 802.11 standards, buses, environment control networks, sensor units (various types including image, voice, electrical, motion, humidity, flow, etc.), actuator units (various types including light sources, motion, pumps, sounders), field units (collective term for sensor, actuator, sensor/actuator units), remote powering.
   • Specific sensor/actuator details: The patent goes into extensive detail about various types of sensors (image, voice, temperature, motion, electrical, etc.) and actuators (light sources, motion actuators, pumps, sounders), and how they function. It also defines "field unit" as a sensor unit, actuator unit, or sensor/actuator unit.

3. Identify potential combinations and motivations for each independent claim:

   • Claim 1 (System):

     • Core elements: Control server, field units (sensors), actuator units, router, Internet communication.

     • Prior art elements:

       • FIG. 1 clearly shows a residence with internal networks (including a sensor network 12 with sensor units 13a, 13b, 13c) connected to a gateway 11 (which includes router functionality) that connects to the Internet 16 and a server 17. The definitions also state that the gateway (RG) often includes a router.
       • The patent itself defines "server" as a device connected to the Internet providing services to clients.
       • "Environment control networks" are defined as networks of sensors and controllers for optimized environment control (house, farm, city traffic). The disclosure states that a dedicated hardware gateway is required, but then proposes how its disclosure replaces it with a cloud server. This implies the concept of server-based control for environment networks is known, but the specific implementation (replacing the local gateway with a cloud server for control functionality) is key.
       • Suzuki and Inoue specifically describe "moving limited management functions of a home gateway onto network cloud". This is a strong piece of prior art for server-based control, especially for home environments.

     • Combination for Claim 1:

       • Start with the prior art arrangement from FIG. 1 which shows sensor units (field units), a gateway/router, and a server connected via the Internet.
       • Introduce the concept from Suzuki and Inoue which teaches moving gateway management functions to a network cloud (server).
       • A POSITA, aware of the arrangement in FIG. 1 and the teachings of Suzuki and Inoue regarding cloud-based management of home gateways, would be motivated to extend the "limited management functions" to include the control logic for sensors and actuators. The motivation would be to leverage the benefits of cloud computing (scalability, reduced local hardware complexity, centralized management, reliability, cost-effectiveness as mentioned in the patent's own disclosure) for full control functionality, rather than just "limited management." The detailed definitions of various sensors and actuators in the patent show these are well-known components in environment control networks. The "dedicated hardware gateway" mentioned in the disclosure itself indicates the known problem that the patent aims to solve with a cloud server.

   • Claim 13 (Method):

     • Core elements: Control server receives sensor data, executes control logic, generates actuator commands, sends commands via Internet and local router.
     • Prior art elements: Same as Claim 1. The method aspects are inherent in the system elements.
     • Combination for Claim 13:
       • The method described in Claim 13 directly follows from the system described in Claim 1. If the system is obvious, the method of operating it would also be obvious.
       • FIG. 1 shows the flow of information from sensors (field units) through a gateway/router to a server.
       • Suzuki and Inoue teach moving management functions to a cloud server. A POSITA would readily understand that for a server to manage functions, it must receive data, apply logic, and send commands. Extending "limited management" to full "control logic" on the server side, with the router acting as a communication intermediary, would be a logical step for a POSITA to achieve the known benefits of cloud computing, such as centralized control and processing power.

   • Claim 14 (Image Sensor):

     • Core elements: Image sensor in field unit, control server receives image data, processes image data (face detection, recognition, motion sensing), control logic based on image processing, actuator commands.

     • Prior art elements:

       • The patent extensively defines "image sensor" as a CCD or CMOS based sensor for capturing still or video images, and mentions "image processing" functionalities like face detection, face recognition, gesture recognition, compression/decompression, and motion sensing as known. It also states these functionalities "may be in the field unit, in the router (or gateway), in the control server, in a computer in the building (or vehicle), or any combination thereof." This explicitly teaches that image processing can be performed in the control server.
       • The general concept of "environment control networks" and the use of "sensors" is present in FIG. 1 and the general definitions.
       • Suzuki and Inoue's concept of cloud-based management.

     • Combination for Claim 14:

       • Start with the obvious system and method from Claims 1 and 13, which combine FIG. 1 and Suzuki and Inoue.
       • Integrate the widely known concept of using image sensors (as extensively defined in the patent itself, including types like CCD/CMOS and image processing techniques like motion sensing, face detection/recognition). The patent's own definitions explicitly state that image processing functionality can be in the control server.
       • A POSITA would be motivated to combine a cloud-based environmental control system (from FIG. 1 and Suzuki & Inoue) with known image sensor technology and server-side image processing. The motivation would be to enhance the control capabilities of the environmental system with advanced visual input for security, occupancy detection, activity monitoring, etc., leveraging the server's computational resources for complex image analysis as explicitly taught by the patent's own descriptions. For example, if a "limited management function" in Suzuki and Inoue's system was to monitor security, integrating an image sensor and performing motion sensing (a defined image processing function) on the cloud server would be a natural extension to improve security.## Obviousness Analysis under 35 U.S.C. § 103 for US11128710

This analysis considers whether the claims of US patent 11128710 would have been obvious to a person having ordinary skill in the art (POSITA) at the time of the invention, based on the provided prior art. The key aspect of US11128710 is its server-based control system, where a remote control server performs the core control logic, interacting with local field units (sensors and actuators) via a router and the Internet.

General Considerations for Obviousness

To establish obviousness, it must be shown that the claimed invention as a whole would have been obvious to a POSITA. This typically involves identifying a primary prior art reference that teaches most elements of the invention and then finding secondary references that teach the remaining elements. Crucially, there must be a clear and articulable reason or motivation for a POSITA to combine these references to arrive at the claimed invention, with a reasonable expectation of success. Such motivations can include improving existing devices or methods, fulfilling a known need, or applying known techniques to a new field.

Analysis of Independent Claims

Independent Claim 1: Control System

Claim 1 describes a control system for an environment comprising:

• a plurality of field units (at least one sensor unit, at least one actuator unit)
• a router in the environment for communicating with the field units
• a control server in a remote location, coupled to the router via the Internet
• the control server configured to receive sensor data from the sensor unit, execute a control logic based on the sensor data, and transmit actuator commands to the actuator unit.

Prior Art Combination:

1. Primary Reference: FIG. 1 (Prior Art Arrangement 10)

   • FIG. 1 depicts a residence (environment) 19 with multiple internal networks, including a sensor network 12 connecting sensor units 13a, 13b, 13c.
   • A gateway 11 is connected to these various networks, allowing communication between devices and providing external connection to the Internet 16, typically via a WAN network.
   • The gateway 11 is described as "sometimes referred to as Residential Gateway (RG) or Home Gateway," and "may include a broadband modem (such as DSL or cable modem), a firewall, a router, a packet-switch, and a Wireless Access Point (WAP)." This clearly teaches the presence of a router within the environment, communicating with sensor units (field units) and connecting to the Internet.
   • The arrangement further shows a server 17 connected to the Internet 16, which the residence 19 may be connected to.
   • The patent defines "sensor unit," "actuator unit," and "sensor/actuator unit" as collectively "field units," and provides extensive examples of both, indicating their known existence in various control applications. The concept of "environment control networks" comprising sensors and controllers for optimized control in a house is also explicitly acknowledged as prior art.

2. Secondary Reference: Katsuya Suzuki and Masahiro Inoue, "Home Network with Cloud Computing for Home Management" (2011)

   • This paper describes a "prior-art architecture involving moving limited management functions of a home gateway onto network cloud."
   • The patent itself defines "Cloud computing" as a "technology infrastructure facilitating supplement, consumption and delivery of IT services" and "SaaS" (Software as a Service) as a model where a provider licenses an application to customers for use as a service on demand. It also states that "SaaS is becoming ever more common as a form of SA delivery over the Internet and is being facilitated in a technology infrastructure called 'Cloud Computing'."

Motivation for Combination:

A POSITA, examining the prior art arrangement of FIG. 1, would recognize a system for local environmental monitoring and control connected to the Internet. However, the control logic itself, in such a traditional setup, would typically reside within the local gateway 11 or other local controllers.

The teaching by Suzuki and Inoue to move "limited management functions of a home gateway onto network cloud" would provide a clear motivation for a POSITA to consider centralizing more functions, including the primary control logic, on a remote server. The patent's own disclosure highlights the advantages of such a server-based approach over dedicated hardware gateways, stating it offers "much better cost, reliability and level of service."

Therefore, a POSITA, seeking to improve the cost-effectiveness, reliability, and service level of an environmental control system like that shown in FIG. 1, and knowing that management functions can be moved to a cloud (server) as taught by Suzuki and Inoue, would be motivated to relocate the "control logic" (which is a management function in a broader sense) from the local gateway/router to the remote server 17. This would involve the server receiving sensor data (already passing through the router to the Internet as per FIG. 1), processing it with control logic at the server, and sending actuator commands back through the Internet and router to the local actuator units (which are common components in "environment control networks" as defined). The transition from "limited management functions" to full "control logic" on the server would be a straightforward extension for a POSITA aiming to fully realize the benefits of cloud computing for environmental control.

Independent Claim 13: Method of Control

Claim 13 describes a method for controlling an environment, comprising:

• providing a plurality of field units (at least one sensor unit, at least one actuator unit) in an environment
• providing a router in the environment
• coupling a control server in a remote location to the router via the Internet
• receiving, by the control server, sensor data from the sensor unit via the router and the Internet
• executing, by the control server, a control logic based on the received sensor data
• transmitting, by the control server, actuator commands to the actuator unit via the Internet and the router to control a physical phenomenon in the environment.

Prior Art Combination and Motivation:

The method steps outlined in Claim 13 are the operational steps of the system described in Claim 1. Given that the system of Claim 1 would be obvious by combining FIG. 1 and Suzuki and Inoue, the method of operating such a system would also be obvious to a POSITA.

• FIG. 1 illustrates the flow of information from sensors through a gateway/router to a server, and implicitly the reverse path for control.
• Suzuki and Inoue provide the motivation for performing functions (specifically "management functions") on a remote server via cloud computing.

A POSITA implementing the system derived from the combination of FIG. 1 and Suzuki and Inoue would naturally follow the method steps of receiving data at the server, processing it (executing control logic), and sending commands back to the actuators. This is the fundamental operational paradigm of any server-based control or management system, especially one leveraging cloud computing. The "control logic" is simply a more advanced form of "management function" that directly influences physical phenomena, and a POSITA would readily understand how to implement such logic on a remote server for the described environmental control applications.

Independent Claim 14: Control System with Image Sensor

Claim 14 describes a control system similar to Claim 1, but with the additional features:

• at least one of the sensor units comprises an image sensor
• the control server is further configured to receive image data from the image sensor via the router and the Internet
• the control server is further configured to perform image processing on the received image data, the image processing comprising at least one of motion sensing, face detection, or face recognition
• the control logic is further based on the performed image processing.

Prior Art Combination:

1. Primary Combination: Obviousness of Claim 1 (FIG. 1 + Suzuki and Inoue)

   • As established above, the basic server-based environmental control system is obvious through the combination of FIG. 1 (showing a local sensor/actuator network connected to a router and the Internet to a server) and Suzuki and Inoue (teaching moving gateway management functions to a network cloud).

2. Secondary Reference: Patent's Own Disclosure on Image Sensors and Processing

   • The patent extensively defines "image sensor" as a known technology, including CCD or CMOS based sensors for capturing still or video images.
   • Crucially, the patent explicitly states that "the image processing functionality may be in the field unit, in the router (or gateway), in the control server, in a computer in the building (or vehicle), or any combination thereof."
   • It also lists "face detection, face recognition, gesture recognition, compression or de-compression, or motion sensing" as known "image processing" techniques.
   • The patent further defines "a sensor operation may be based on an external or integral mechanism for generating a stimulus or an excitation to generate influence or create a phenomenon." This supports the idea of using sensor input, like image data, to influence control.

Motivation for Combination:

A POSITA, having established the basic server-based environmental control system (from FIG. 1 and Suzuki & Inoue), would be motivated to enhance the system's capabilities using various sensor types. The patent itself identifies "image sensor" as a type of sensor that can be included in a field unit.

Given the explicit teaching within the patent that "image processing functionality may be... in the control server" and the known image processing techniques like "motion sensing, face detection, or face recognition", a POSITA would readily combine the server-based control system with an image sensor. The motivation would be to introduce advanced visual input for environmental control applications. For example, for a "home management" system (Suzuki and Inoue), adding motion sensing via an image sensor processed by the server would enable more sophisticated security features or occupancy-based control (e.g., turning lights on/off, adjusting HVAC based on presence). The server's computational power (a known advantage of cloud computing) would naturally be leveraged for computationally intensive tasks like image processing, as the patent itself suggests.

Conclusion

Based on the analysis, the independent claims of US patent 11128710 appear to be obvious under 35 U.S.C. § 103. The core innovation of a remote server performing control logic for local sensors and actuators via a router and the Internet is directly addressed by combining the general environmental control setup of FIG. 1 with the concept of moving gateway management functions to a network cloud, as taught by Suzuki and Inoue. The inclusion of specific sensor types like image sensors and their associated processing on the server is also explicitly contemplated as known functionality and placement within the patent's own detailed definitions, making their integration into an already obvious server-based control system a matter of routine design choice for a POSITA.
