  • Method and apparatus for CAN bus auto-termination
    Patent number: 7312628
    Abstract: A cable area network (CAN) bus termination (100) is provided by an interface 104 operably coupling a cable detection input pin (3), a switch (120) and a termination resistance (130) to detect the presence and absence of one or more cables (108). The termination resistance (130) is automatically enabled to create terminations at end nodes and is automatically disabled to provide a daisy-chain connection between interim nodes of a multi-cable system.

  • Self-clocking automatic digital level control method and apparatus
    Patent number: 6324229
    Abstract: An automatic digital level control adjuster (310) processes an analog input signal (305) to adjust its signal level, based on input (311) from a digital module (330) that is clocked by a clock signal (325) derived from the analog signal (305). Preferably, the input (311) from the digital module (330) changes at a rate dependent on the clock signal (325), and such changes are made during crossovers of the analog signal across a predetermined zero reference threshold.
