  • Publication number: 20140292729
    Abstract: An electronic device is configured to determine a location of a stylus with respect to a display screen dependent upon first and second timing signals. A change in state of a reference pixel cell is detected using a photodetector located in close proximity to the reference pixel cell and a change in state of a pixel cell in proximity to the stylus, in response to a stylus photodetector signal received from a photodetector of the stylus. The location of the stylus with respect to the display screen is determined from the time difference between the change in state of the reference pixel cell and the change in state of the pixel cell in proximity to the stylus.

  • Publication number: 20140286407
    Abstract: A system and method for resilient signal encoding provide for encoding a data signal to reduce bandwidth required to transmit the encoded signal while mitigating the impact of frames lost or corrupted during transmission. A first frame of the data signal is encoded as an independently decodable frame and is assigned as a reference frame. Subsequent frames of the data signal are encoded as different frames relative to the reference frame. The independently decodable frame and the difference frames are transmitted to a receiver. The receiver decodes the frames and sends an acknowledgement for one or more successfully decoded difference frames. When an acknowledgment is received, a corresponding data signal frame is assigned as the reference frame. Subsequent difference frames are encoded relative to the newly assigned reference frame.

  • Publication number: 20140273905
    Abstract: In a radio receiver, a method of reducing second order distortion components, involves at a first mixer, mixing an input signal with an oscillator signal to generate an I component of a received radio signal; at a second mixer, mixing the input signal with a phase shifted oscillator signal to generate a Q component of the received radio signal; where the I and Q components of the received signal have a receive bandwidth; computing an estimate of second order distortion components as a power output of the I and Q components between approximately the receive bandwidth and twice the receive bandwidth of the received radio signals; and adjusting an operational parameter of the radio receiver to reduce the estimated value of second order distortion components. This abstract is not to be considered limiting.

  • Publication number: 20140269357
    Abstract: A system and method that may facilitate transmission bandwidth savings in non-stationary vehicle-to-vehicle wireless communication channels. At a transmitting vehicle, a transmitter may adaptively change the number of pilot symbols or pilot rate within a frame based upon the current channel statistics. The transmitter may utilize a look-up table approach to select a best pilot rate based upon current conditions associated with the transmitting vehicle, and/or a new frame structure to transmit pilot rate information. At the receiving vehicle, the receiver may be configured to detect a unique waveform transmitted by the transmitting vehicle to estimate the pilot rate information. Alternatively, the receiver on the receiving vehicle may be configured to predict and verify the pilot rate information from an encoded data symbol embedded within a frame transmitted by the transmitting vehicle, which may entail a detection algorithm using encoded data symbols and/or an estimation algorithm using channel statistics.
