  • High voltage latching and DC restoration isolation and level shifting method and apparatus
    Patent number: 8717063
    Abstract: A device and method for dc isolation and level shifting includes a driver circuit powered by a first voltage range, a capacitor connected to the driver circuit, and a latching circuit connected to the capacitor. The latching circuit is powered by a second voltage range and is configured to restore and/or minimize charge loss of the capacitor during a voltage transition at the capacitor. A device and method for analog isolation and measurement configured to measure an analog voltage at a second potential without requiring analog circuits at the second potential.

  • Folded ribbon cable assembly having integral shielding
    Patent number: 5162611
    Abstract: The present invention provides two ribbon cable for conducting AC power and digital data signals respectively. A pliable insulating material holds together and electrically insulates the conductors on each ribbon cable. Conductive material, such as a conductive foil or conductive plastic serves to shield the electromagnetic interference generated by the transmitted AC power from the data conductors. The ribbon cables are folded in a protective outer jacket so that the conductive material is disposed substantially between the power conductors and the data conductors. This maximizes the electromagnetic interference shielding of the conductive material.
