  • Patent number: 11943582
    Abstract: A sound enhancing device for improving voice reception of a smartphone microphone is attachable to the rear surface of a smartphone opposite the surface of the smartphone having a display. The device has a deflector in a sliding engagement within a cavity of a housing moveable between a stowed position and a deployed position. A reflective curved area positioned on a first surface of the deflector captures and reflects sound waves from the voice of a user toward a microphone of the smartphone.

  • Patent number: 8686759
    Abstract: An AUX channel amplifier for amplifying data in the AUX channel of a Display Port device. In some embodiments, the amplifier includes a first amplifier coupled to amplify a signal from a source to a sink and a second amplifier coupled to amplify a signal from the sink to the source. A slicer can be utilized to digitize the signal from the source. In some embodiments, a clock and data recovery can be utilized to receive signals from the source and a second clock and data recovery can be utilized to receive signals from the sink. A controller determine the direction of data flow and enables the first amplifier or the second amplifier accordingly.

  • Patent number: 8212594
    Abstract: Clock-domain-crossing systems and methods include an integrator that accumulates input samples over multiple clock cycles in a first clock domain to generate an accumulation result. Clock-domain-crossing circuitry samples the accumulation result in the first clock domain after each of a repeating accumulation count to generate a first domain accumulation. The first domain accumulation is sampled in a second clock domain after a time delay to generate a second domain accumulation. The time delay ensures proper setup and hold time parameters for the second clock domain relative to the first clock domain. A differentiator generates output information in the second clock domain by delaying the second domain accumulation and subtracting the delayed second domain accumulation from the second domain accumulation. The systems and methods preserve temporal characteristics of the input information in the first clock domain when it is transferred to the second clock domain as the output information.
