  • Verticle probe card for attachment within a central corridor of a magnetic field generator
    Patent number: 6556031
    Abstract: A vertical probe card assembly containing a plurality of vertical probe cards is mounted within a central corridor or opening within a magnetic field generator. Each of the vertical probe cards has a multiplicity of probe needles extending downwardly therefrom for electrically contacting test pads of a device under test that is positioned below the magnetic field generator.

  • Method & apparatus for managing alternator loads on engines
    Patent number: 5038728
    Abstract: The improved engine load management system of the present invention includes an apparatus that will de-excite the field coils of an alternator that is driven by an internal combustion engine when the battery that the alternator charges is above a required minimum voltage and when the engine is operating under high load conditions such as acceleration or climbing. When the battery charge falls below the required minimum, the apparatus excites the alternator field coils and permits the alternator to charge the battery despite a high engine load condition. When the battery charge is above the minimum required voltage, but below the voltage at which charging is discontinued, and the engine is under high load, the alternator field coils are energized and de-energized in a cycle that reduces alternator drag on the engine, but permits limited battery charging to occur.
