  • Multi-conductor plug and socket apparatus
    Patent number: 7462957
    Abstract: An electronic switching circuit system designed to be compatible with coaxial barrel style plug and socket connectors. Specific plug and socket contacts utilize a simple electronic device that causes the switching circuit associated with either or both the plug and socket to be activated only when the plug and socket pair is fully engaged.

  • Apparatus for receiving downhole acoustic signals
    Patent number: 6956791
    Abstract: The invention relates to an apparatus for receiving downhole acoustic signals, processing the signals into electric signals, then transmitting the signals wirelessly to a remote above-surface monitoring station. The apparatus is mountable to an above-surface rotatable component used in borehole application. The apparatus includes an instrument housing, and a clamping assembly attached to the housing and having sufficient length and flexibility to enable the apparatus to surround the perimeter of the rotatable component.

  • Circuit to mitigate transformer shorted turn
    Patent number: 6816053
    Abstract: A dual transformer design, each transformer having at least a primary winding and a secondary winding disposed on a core means, wherein the core means is circumferentially disposed about an inner housing means, and the whole structure located within an outer housing. The primary winding of one transformer of said pair of transformers is electrically coupled to the primary winding of the other in a manner such as to cause induced eddy currents from one transformer to be of a magnitude and direction so as to substantially cancel the induced eddy currents from the other transformer.
