  • Publication number: 20130331086
    Abstract: A smartphone or other portable electronic device is used to control another electronic device using the existing audio output of the phone without modification. The audio link can be ultra-sonic, sub-sonic, or audible and, if the controlled device has an audio output, bi-directional communications may be achieved using the microphone of the smartphone. The smartphone acts as a control panel to program or operate the external device. In one disclosed example, the smartphone is used to control and tune a portable sports event radio using an acoustic link and tone pattern(s).

  • Patent number: 8576083
    Abstract: A rain detector for use with an automotive vehicle. The rain detector includes a capacitance sensor mounted to the inside surface of a windshield. The sensor includes at least two output lines which vary in capacitance as the function of magnitude of rain on the outside surface of the windshield. A programmed microcontroller receives the sensor output lines as analog input signals and then compares the magnitude of the capacitance with a threshold capacitance. In the event that the sensed capacitance exceeds the threshold capacitance, indicative of raindrops on the outside surface of the windshield, the microcontroller generates an output signal to the wiper control circuitry of the vehicle to activate the windshield wiper system.

  • Patent number: 8566043
    Abstract: A detector for calculating the distortion of an electromagnetic field produced by a buried current carrying conductor comprises three antennas B, M, T. Outputs of two pairs of antennas are compared and the depth of the buried conductor is calculated using two different methods. If there is a significant difference in the two calculated depths then it is deemed that the electromagnetic field produced by the buried current carrying conductor is significantly distorted by the material in which the conductor is buried.

    Abstract: A method is provided in one example embodiment and includes generating a request for header data, the request is sent to a first processor. The method also includes receiving a response from the first processor that is indicative of video data for a virtual frame to be communicated. A multiplex table is generated based on the response. The method also includes evaluating a multiplex entry in the multiplex table for synchronization with a line number, and requesting the first processor to send at least a portion of the virtual frame after the synchronization. The method further includes communicating a packet, which includes a payload associated with the virtual frame and a packet header that includes multiplex data associated with the multiplex entry.

  • Patent number: 8355398
    Abstract: Systems and methods for real time data processing using a switching network and multiple digital signal processors (DSPs). In an embodiment, the system includes a first digital signal processor having a video port interface, a first interface disposed between the video port interface of the first digital signal processor and a switching network, a second digital signal processor having a video port interface, and a second interface disposed between the video port interface of the second digital processor and the switching network. The first interface is configured to parse a VSYNC line of a video frame that is output from the first digital signal processor via its video port interface to generate a multiplexing table based upon which scan lines of the video frame are broken up into packets compatible with the switching network such that the packets can be transmitted over the switching network and be received by the second interface and the second digital signal processor via its video port interface.

  • Patent number: 8115489
    Abstract: A detector for detecting a buried conductor comprises a plurality of antennas B, T. Each antenna B, T has a winding wound around the antenna, the winding being connected to a current source for providing a predefined current in the winding. When the predefined current is applied to the winding an electromagnetic field is generated at the antenna which induces a test current in the antenna. The test current is compared to calibration data stored in the detector to validate the correct operation of the detector.
