  • Method and apparatus for communicating data with a transponder
    Patent number: 6356738
    Abstract: A method and system for communicating data between controller and a transponder where the processor is powered by current received from an antenna. The controller is magnetically coupled to the transponder to sense impedance variations in the transponder. The impedance of the transponder is altered by varying current used by a processor within the transponder. The processor current is controlled by varying the processor clock rate.

  • Document scanning system
    Patent number: 4686581
    Abstract: The invention provides a scanner system which in one embodiment includes only a single moving part in the document path, namley a drive roll, which serves not only to move the document through the system, but also to provide a backing against which the document is pushed while a proximate region thereof is being scanned. The invention in an embodiment also provides an opto-mechanical assembly that is shock-mounted to the frame of the system at only three-spaced apart locations, so that the assembly tends to be isolated from vibration and torsional forces.
