  • Patent number: 8487912
    Abstract: In one embodiment, control circuitry receives an indication of a current position of an input object on a capacitive touch sense device. The control circuitry determines whether a difference between a previous position and the current position exceeds a predetermined hysteresis threshold. If the determined difference does not exceed the predetermined hysteresis threshold, the control circuitry masks the current position of the input object on the capacitive touch sense device.

  • Patent number: 8484487
    Abstract: A method and a system for supplying power to a microcontroller with a single cell. One embodiment of the present invention discloses incorporation of a power supply pump circuit with the microcontroller and their dynamic interaction. The microcontroller sends its power requirements to the power supply pump circuit and in response, the power supply pump circuit controls the operating voltage with optimal efficiency. The dynamic update of power supply pump circuit results in an efficient use of the power supply pump circuit and thus results in a reduction of the number of dry cell batteries to only a single cell. Incorporation of the microcontroller and power supply pump circuit onto a single chip reduces the pin number requirements as well as the space required on the printed circuit board.

  • Patent number: 8483259
    Abstract: An improved method of framing data packets in a direct sequence spread spectrum (DSSS) system that uses one pseudo-noise code (PN-Code) to frame the packet with a start-of-packet (SOP) and end-of-packet (EOP) indicator, and a different PN-Code to encode the data payload. Furthermore, the SOP is represented by the framing PN-Code, and the EOP is represented by the inverse of the framing PN-Code. This method creates a robust framing system that enables a DSSS system to operate with a low threshold of detection, thus maximizing transmission range even in noisy environments. Additionally, the PN-Code used for the SOP and EOP indicators can be used to indicate an acknowledgement response.
