  • Connecting multiple batteries to battery powered devices
    Patent number: 5621301
    Abstract: A circuit for serially connecting multiple batteries to a battery-powered device such as a notebook computer or camcorder so that the device will serially charge or discharge the batteries. The device includes at least two controllable switch circuits for selectively connecting batteries to the battery-powered device, a power flow sensor for sensing power flow from the device to the selected battery or vice-versa, and a selector circuit for sequentially enabling the switch circuits to sequentially connect the batteries to the battery-powered device so that the batteries will sequentially charge or discharge.
    Type: Grant

  • Wideband radar detector
    Patent number: 5305007
    Abstract: A wideband radar detection apparatus includes a signal detection section, high rate signal processing section and a low rate signal processing section. The signal detection section sweeps through a range of preselected frequencies and generates an output signal having a pair of single cycle sinusoids for every detected signal. The output signal is provided to the high rate signal processing section and a Sliding Window Discrete Fourier Transform is performed thereon to generate a set of complex values that are related to the fundamental energy content at consecutive points in the sweep. The low rate signal processing section controls sweep parameters and also evaluates the complex values. If the magnitude of the complex values exceed a predefined threshold, then an alert is indicated.
