  • Patent number: 11774613
    Abstract: A seismic data acquisition unit includes a housing, and disposed within the housing, communication circuitry, and circuitry configured to detect and digitize seismic signals. The communication circuitry includes a first transmitter plate, a second transmitter plate, a first receiver plate, a second receiver plate, and a driver. The first and second transmitter plates, and first and second receiver plates, are adjacent a wall of the housing. The driver is coupled to the first transmitter plate and the second transmitter plate. The receiver is coupled to the first receiver plate and the second receiver plate. The communication circuitry transmits digitized seismic signals via a first capacitor that includes the first transmitter plate, and a second capacitor that includes the second transmitter plate. The communication circuitry receives information via a third capacitor that includes the first receiver plate, and a fourth capacitor that includes the second receiver plate.

  • Patent number: 11262467
    Abstract: A seismic data acquisition unit includes circuitry to detect and digitize a seismic signal, and timing circuitry to control a time of acquisition of each sample of the seismic signal. The timing circuitry include a voltage controlled oscillator (VCO), a local clock incremented by the VCO, and a reference time receiver. The timing circuitry powers on the reference time receiver to generate a reference time value based on signals received from a reference time source, and measures time deviation of the local clock from the reference time value. The timing circuitry determines an adjustment value to apply to the VCO over a time interval during which the reference time receiver is not powered on. The adjustment value is selected to gradually bring the local clock into synchronization with the reference time source over the time interval at a time that the reference time receiver is to be next powered on.

  • Patent number: 10310110
    Abstract: A system for seismic data acquisition includes data recorders that lack external electrical connectors. A seismic data recorder includes a housing. Within the housing the seismic data recorder includes circuitry configured to detect and digitize seismic signals and communication circuitry. The communication circuitry includes a first transmitter plate adjacent a wall of the housing, and a first driver coupled to the first transmitter plate. The communication circuitry configured to communicate the digitized seismic signals to a data retrieval unit that is external to the data acquisition unit via a capacitor formed by the first transmitter plate, the wall of the housing, and a receiver plate external to the housing.
