  • Publication number: 20070062744
    Abstract: An electronically reconfigurable battery includes a number of battery modules selectively interconnected by a number of electronic switches, wherein a selectable number of battery modules may be connected either in a series configuration or in a parallel configuration, as a result of placing selected switches of said plurality of switches in open states or closed states. In a parallel configuration, the battery provides power to a primary load, such as a propulsion load for a vehicle. In a series configuration, the battery is configured to provide a high voltage and high power output to a short-term and/or pulsed load, such as an additional load provided on the vehicle.

  • Publication number: 20050047459
    Abstract: A laser-activated semiconductor switching device has a semiconductor structure housed in a semiconductor structure housing, and a laser array assembly directly connected to the semiconductor structure housing. The laser array assembly houses a plurality of laser diodes and diode control circuitry which energizes the laser diodes to emit light directly onto a surface of the semiconductor structure, which can be the cathode or anode surface, or both, to cause the semiconductor structure to generate current carriers which enable passage of current through the semiconductor structure. The surfaces of the semiconductor structure can be covered with metal layers having openings which permit the passage of the laser light into the semiconductor structure. The metal layers are reflective to the laser light and prevent the laser light that has passed into the semiconductor structure from exiting the structure to improve current carrier generation.
