  • Isolation monitor
    Patent number: 9046559
    Abstract: An isolation monitor is disclosed in which a switchable bias voltage is imposed on a chassis ground. An isolation voltage is measured when a bias voltage is applied. When there are no electrical faults, the isolation voltage swings up and down to known values. When a fault occurs, the isolation voltage will not to swing to the known values, and thus the isolation resistance can be measured and alarm generated if the isolation resistance falls below a threshold value.

  • Dual mode regulated light-emitting diode module for flashlights
    Publication number: 20050007770
    Abstract: An LED illumination module for a flashlight has a housing, electronic control circuitry, and one or more LEDs connected in series and to the circuitry. The module is characterized in that the module is shaped to modularly replace an incandescent-bulb in an existing flashlight. In one aspect the control circuitry operates in a dual mode to extend life of the unit, and to warn when battery replacement is warranted.
