摘要： The present disclosure describes a system 400 for transmitting power to a remote Power over Ethernet (PoE) subsystem by forwarding Powered Device (PD) input voltage where the subsystem includes a PD and a Power Sourcing Equipment (PSE) device. Included is a master PSE device 402, a first subsystem 410, and a second subsystem 428. The first subsystem 410 includes a first PD 418 that includes a first power switching device 426 and a first PSE device 424. The first power switching device 426 forwards the input power from the first PD 418 to the first PSE 424 without disturbing the PoE handshaking between the devices. The first power switching device 426 uses a switching device with level detection that detects the required input voltage. The second subsystem 428 receives the power from the first subsystem's 410 first PSE device 424. And the second subsystem 428 operates in a manner similar to the first subsystem 410.

摘要： This disclosure describes a system (100, 130) for a USB to Bluetooth audio bridging method and apparatus. The system includes a host device (102) having a first universal serial bus (USB) interface (107) and a second USB interface (110); an adaptor (108) in connection with the first USB interface (107) which is compatible to operate based on a Bluetooth-type communication protocol; a peripheral device (106) coupled to the second USB interface (110); and a mobile communication device (104) linked to the host device (102) via the adaptor (108). The mobile communication device (104) communicates an audio data signal to the adaptor (108) and an audio bridging device (116). The audio bridging device (116) maps the second USB interface (110) to the adaptor (108) and routes audio data signals alone or in combination with another audio data signals to the peripheral device (106) via the second USB interface (110).
