Steven Cartier has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Portable light having flexibly branched arms with LEDs
    Patent number: 6866395
    Abstract: A portable light has a weather resistant body and plural elongate, flexible branches, each having an LED lamp. The branches are independently bendable and hold their positions when bent so that light from the plural LEDs may be directed toward different objects. The portable light of the invention is suitable for outdoor use, which can be hand-held, hung overhead, or placed on a table or work surface.
    Type: Grant

  • Method and circuit to bias output-side width modulation control in an isolating voltage converter system
    Patent number: 6510062
    Abstract: The output-side referenced pulse width modulator (PWM) in an isolation-providing voltage converter receives at least initial bias voltage (Vbias) from a charge-pump like Vbias generator. The Vbias generator includes an input-side referenced periodic waveform generator whose output signal can be amplified differentially with an input-side referenced circuit and then AC-coupled via isolation-maintaining capacitors to an output-side referenced rectifier circuit whose output is Vbias. The Vbias thus generated can power the PWM at least from power-up through commencement of steady-state operation, when a more robust Vbias can be derived from the output-side voltage itself. Since the PWM is output-side referenced, high feedback bandwidth is maintained.
