  • Method and apparatus for electronic item identification in a communication system using known source parameters
    Patent number: 6970518
    Abstract: A communications method including the steps of: receiving signals from at least one signal source during a first signal source transmission; estimating at least one signal source parameter based on the received signals during the first signal source transmission; receiving signals from at least one signal source during a second signal source transmission; and determining a difference between the first and second signal source transmissions using the at least one estimated signal source parameter.
    Type: Grant

    Date of Patent: November 29, 2005
    Assignee: Motorola, Inc.
    Inventors: Stephen Kuffner, Timothy Collins, Bruce Eastmond, David P. Gurney
  • Method and apparatus for wireless data transfer
    Publication number: 20050135504
    Abstract: A method and apparatus for wirelessly transmitting data between two devices (101, 102) is provided herein. During data transmission, a data and a strobe signal are transmitted simultaneously on the I and Q-channels, respectively, of over-the-air interface. More particularly, QPSK modulation is utilized, with the strobe signal being transmitted via the I-channel, and the data signal being transmitted via the Q channel, (or vice versa). Additionally, illegal constellation transitions are utilized to signal the transmission of control information.
