  • Patent number: 11394377
    Abstract: An embodiment in accordance with the present invention provides a system and method of physically modulating a digital signal across a medium. A signal is sent one bit at a time (serially) as a period of high voltage followed by a period of low voltage. The present invention includes several major advantages. One advantage is that the code to execute the method is very lightweight. Another advantage is that the signals require no synchronization source. The signals of the present invention function as their own synchronization.

  • Patent number: 11334516
    Abstract: This disclosure relates generally to systems and methods of translating between Universal Serial Bus (USB) and synchronous serial protocols. In one embodiment, an apparatus includes an application-specific integrated circuit (ASIC) configured to operate in a multi-protocol generic mode and in an adaptive clock mode. The ASIC is configured to implement a multi-protocol generic command processor in the multi-protocol generic mode where the ASIC is operable to be commanded so as to execute a generic bus command that converts between the USB protocol and any commanded synchronous serial protocol. Furthermore, the ASIC can synchronize the execution of the generic bus command with an externally generated clock signal on the synchronous serial side when the ASIC is also provided in the adaptive clock mode. In this manner, a computer device with a USB port can use the ASIC as a bridge for data communications with a radio having a synchronous serial port.

    Abstract: An endpoint among a plurality of endpoints, synchronizes a clock across the plurality of endpoints. The endpoint generates a received ultrasonic signal by transducing ultrasonic sound received at a microphone from a spatial region. The ultrasonic sound includes an identical ultrasonic signal transmitted from the plurality of endpoints and echoes from the spatial region. The identical ultrasonic signal is generated with respect to the synchronized clock. The endpoint computes an error signal based on removing the identical ultrasonic signals and the echoes from the received ultrasonic signal.

  • Patent number: 8723672
    Abstract: A plurality of hazard alarm devices are in spatially diverse locations and coupled together with an input-output bus. An interconnect protocol enables non-originating alarm devices to synchronize their audible alert tone pulses with audible alert tone pulses from an originating alarm device in a local hazard alarm condition. Hence, all audible alert tone pulses start sounding substantially together with allowances for signal contention and arbitration between the spatially diverse alarm devices. The originating alarm device continuously sounds its pattern of audible alert tone pulse groups without interruption, while the non-originating alarm devices periodically pause sounding a group of their audible alert tone pulses. The originating alarm device may be found by listening for the alarm device that is continuously sounding audible alert tone pulse groups without pause.
