  • Antenna and system for RF communications
    Patent number: 11031672
    Abstract: An antenna includes two planar coils that are mechanically disposed face to face and electrically connected in series. The antenna is mounted to a disposable consumer product (for example, a cartridge for use with an electronic cigarette). The antenna is configured to support near field communications with a reader circuit for purposes of authenticating use of the disposable consumer product.
    Type: Grant

  • LCD driver with adjustable contrast
    Patent number: 7388565
    Abstract: An LCD display driver provides adjustable contrast independent of multiplexing requirements by generating each COM signal in a time slot of a repeating signal frame, with each COM signal containing one or more active periods and one or more inactive periods. The relative time proportions of these periods are adjustable. Corresponding SEGMENT signals turn on/off required segments while maintaining an essentially zero DC component. The logic levels and the relative active time and inactive times of the COM and segment signals being adjustable for increasing or decreasing the RMS voltage levels across the LCD element as desired.
