  • Patent number: 10202846
    Abstract: A downhole telemetry well system transmits data at a high rate inside a tubular pipe by encoding signals on a Stoneley wave. Telemetry devices for the Stoneley mode are implemented in short pipe joints inserted at various intervals between the tubulars. Each telemetry device includes Stoneley transducers, which may act as a transmitter, receiver, or repeater. The Stoneley telemetry devices transmit and receive the Stoneley waves making up the carrier of the signal. The Stoneley telemetry devices may be powered by on-board batteries or via some remote power source.

  • Patent number: 8365400
    Abstract: A circuit board structure comprising a composite layer, a fine circuit pattern and a patterned conductive layer is provided. The fine circuit pattern is inlaid in the composite layer, and the patterned conductive layer is disposed on a surface of the composite layer. After fine circuit grooves are formed on the surface of the composite layer, conductive material is filled into the grooves to form the fine circuit pattern inlaid in the composite layer. Since this fine circuit pattern has relatively fine line width and spacing, the circuit board structure has a higher wiring density.

  • Patent number: 7990114
    Abstract: A control system for an electrical power generation system (EPGS) provides overload protection without disconnecting a generator of the EPGS from an excessive electrical load. Available engine power and current levels of the electrical load are continuously measured. A command voltage is calculated that corresponds to a voltage required to sustain with the maximum available power. Output voltage of a generator of the EPGS is controlled at the calculated command voltage so that a power limit of the engine is not exceeded during electrical overload conditions.
