US Patent: 11031677

• Title: Multiple-body-configuration multimedia and smartphone multifunction wireless devices
• Assignee: Fractus SA
• Inventors: Carles Puente Baliarda, Josep Mumbru, Jordi Ilario
• Filing Date: March 27, 2020
• Issue Date: June 8, 2021

Abstract:
A multifunction wireless device (MFWD) is disclosed, featuring at least multimedia functionality, smartphone functionality, or both. This device comprises an upper body and a lower body designed to move relative to each other in clamshell, slide, or twist configurations. The MFWD also includes an antenna system located within either the upper or lower body. The antenna's contour possesses a specific level of complexity, defined by complexity factor F21 having a value between 1.05 and 1.80, and a value between 1.10 and 1.90 for an unspecified second complexity factor (implied to be F32 from other patent text descriptions).

Plain-Language Overview of Independent Claims (as inferred from the "Definitions" section, as formal claims numbering was not provided in the authoritative text):

1. Claim 1 (Inferred): A multifunction wireless device (MFWD) that includes at least multimedia or smartphone capabilities. This MFWD has an upper and a lower body designed to move relative to each other (e.g., clamshell, slide, twist). Crucially, it incorporates an antenna system located in either the upper or lower body. This antenna system's shape has a specific complexity level, where its contour is defined by a complexity factor F21 ranging from 1.05 to 1.80, and another complexity factor (implicitly F32) ranging from 1.10 to 1.90.

2. Claim 2 (Inferred): A multifunction wireless device (MFWD) having multimedia or smartphone functionalities. This MFWD specifically includes a microprocessor and an operating system capable of running standard productivity software like word processing, spreadsheets, and slide presentations. It also has at least 1 GB of memory coupled with the microprocessor. The device further comprises an antenna system whose contour's complexity is defined by factor F21 (between 1.05 and 1.80) and factor F32 (between 1.10 and 1.90).

3. Claim 3 (Inferred): A multifunction wireless device (MFWD) with multimedia or smartphone capabilities. This MFWD is equipped with a receiver for analog or digital sound signals, and an image recording system that includes at least one of: an image sensor of at least 2 Megapixels, a flash light, an optical zoom, or a digital zoom. It also features data storage with a capacity of at least 1 GB. Similar to the other claims, it includes an antenna system with a contour complexity defined by factor F21 (between 1.05 and 1.80) and factor F32 (between 1.10 and 1.90).

Uncertainty Note: The provided "Full patent text" contains a "Definitions" section that describes aspects of the invention and what appears to be summaries of independent claims. However, it lacks the formal "Claims" section with numbered claims. Therefore, the independent claims overview above is based on the most distinct claim-like descriptions found within the "Definitions" section.
