WUSB Hub Integrating Bluetooth for Isochronous Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wireless Universal Serial Bus (WUSB) hubs struggle with efficiently handling isochronous audio/video connections, degrading performance for other USB peripherals, while Bluetooth communications are slow and lack support for USB peripherals.
Innovation Solution
Integration of a Bluetooth subsystem with a WUSB hub, allowing shared operation between Ultra Wide Band (UWB) and Bluetooth subsystems to streamline device pairing and handle isochronous data operations, enabling efficient cooperation between WUSB and wireless audio/video interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If WUSB hub handles isochronous audio/video connections, then audio/video transmission capability is improved, but performance for other USB peripherals degrades
Solution Approach 1:
The patent segments the wireless communication functionality by integrating both UWB and Bluetooth subsystems within the WUSB hub. This allows separation of isochronous audio/video traffic (handled by Bluetooth) from USB peripheral data traffic (handled by UWB), eliminating resource contention and performance degradation between different device types.
2Adaptability or versatility
If Bluetooth is used for wireless audio communications, then audio transmission is enabled, but communication speed is slow
Solution Approach 1:
The patent merges Bluetooth and UWB subsystems into a single integrated WUSB hub device. This combination allows the system to leverage Bluetooth's strength in isochronous audio streaming while using UWB's high-speed capability for data-intensive USB peripheral communications, achieving both audio versatility and high speed simultaneously.
3Reliability
If separate pairing procedures are used for Bluetooth and WUSB devices, then device compatibility is maintained, but user interaction and setup time increase
Solution Approach 1:
The patent implements a universal pairing mechanism within the integrated WUSB hub that can initiate and coordinate both Bluetooth and UWB pairing procedures through a single user action. The hub's control logic manages the dual-subsystem pairing process, reducing setup steps while maintaining compatibility with standard Bluetooth and USB device pairing protocols.

AI summary
Systems and methods are disclosed that provide WUSB (wireless universal serial bus) and wireless audio/video interfaces within a single device by integrating a Bluetooth subsystem with a WUSB hub and by providing shared operation between the UWB (ultra wide band) and Bluetooth subsystems. In one embodiment, a system includes both a UWB subsystem and a Bluetooth subsystem that are configured to share one or more operational parameters, such as device pairing information. As such, Bluetooth subsystems and the WUSB subsystems are allowed to cooperate and share information to streamline operation, and this streamlining allows the Bluetooth subsystem to handle isochronous operations, such as audio/video communications, and allows the UWB subsystem to continue to handle USB connected peripheral devices. The disclosed systems with WUSB and wireless audio/video interfaces can also be included as subsystems within other devices, such as display monitors or speaker systems for computer systems.
