  • Integrated circuit device having slanted peripheral circuits
    Patent number: 4789889
    Abstract: The present invention sets forth an integrated circuit (IC) device wherein the IC chip includes peripheral circuits, such as input/output circuits, which are arranged non-perpendicular with respect to the rectangular shape of the active area of the IC. This structure permits positioning some of the terminal bond pads closely adjacent the corners of the chip without overlap of adjacent circuits.

  • Digital means for non-invasively controlling the parameters of an implantable heart pacer
    Patent number: 4164944
    Abstract: A heart pacer employing a digital parameter controlling circuit is controlled by externally transmitted magnetic pulses of width corresponding to the desired ultimate parameter controlling signal. In the embodiment shown, a magnetic pulse of width about 5.1 milliseconds corresponds to a digital "0", and a pulse of about 20.5 milliseconds corresponds to a digital "1". Circuits for generating and transmitting the pulses as well as for receiving and controlling the pacer parameters in accordance with the pulses are shown.
