Abstract: A motion detector includes a motion sensor that in one embodiment is an electrically conductive pin that has a fixed upper portion and a lower portion that swings from the upper portion while maintaining electrical conductivity. The lower portion of the pin is located within a hole that has conductive areas. A motion detection circuit identifies movements in a device containing the motion detector by monitoring the electrical contact status between the motion sensor and the conductive areas around the hole.

Abstract: Wireless devices transmit and receive radio signals based upon reference frequencies that are generated by reference frequency circuits. If the reference frequency in the transmitter is different from the reference frequency in the receiver, the radio signals may not be received properly or may not be capable of being received at all. A measurement circuit measures the amount of error or signal corruption in radio signals due to the reference frequency offset. A trimming circuit then tunes the reference frequency in the transmitter or receiver to reduce the reference frequency offset.

Abstract: A wireless device decodes Direct Sequence Spread Spectrum (DSSS) encoded data and identifies data that can not be successfully DSSS decoded (invalid data). A checksum operation uses successfully decoded DSSS data (valid data) to correct the identified invalid corrupted data. The improved error correction leverages the valid and invalid bit information normally provided in DSSS systems to more effectively correct corrupted data bits. The improved error correction increases the processing gain of wireless devices thus increasing the effective wireless range without having to increase transmit power.
