Abstract: Described herein is an ultrasound-based virus shield. The ultrasound-based virus shield may include an ultrasound sonar emitter configured to emit a first sonar signal including a header with key data, and an ultrasound sonar receiver configured to receive a second sonar signal. The ultrasound-based virus shield may include a processor configured to: calculate a distance between the ultrasound-based virus shield and a subject in response to determining that the second sonar signal includes the key data associated with the first sonar signal, and activate an ultrasound sterilizing emitter in response to determining that the distance calculated is less than a threshold distance. An ultrasound sterilizing emitter of the ultrasound-based virus shield may be configured to emit a sterilizing signal.

Abstract: A high definition multimedia interface using a modified format switcher for controlling electronic hardware. The modified format switcher enables infrared, RS-232, TCPIP, audio, and consumer electronics control interconnection with the high definition multimedia interface.

Abstract: A device for transmitting multiple control formats from an audio/video source to an audio/video monitor receiver. The device includes a high definition multimedia interface cable that has a plurality of communication channels, including a consumer electronic control channel. Furthermore, a pair of plugs are coupled to the respective ends of the high definition multimedia interface cable and can be coupled to audio/video sources and receivers. A pair of interface ports are further coupled to the high definition multimedia interface cable and communicatively coupled to the consumer electronic control channel. The device transmits a first control format on the consumer electronic control channel when the input port is not coupled to a switching device and transmits a second control format on the consumer electronic control channel when the input port is coupled to a switching device.
