Patent number: 11774613Abstract: 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.Type: GrantFiled: February 3, 2022Date of Patent: October 3, 2023Assignee: Geospace Technologies CorporationInventors: Robbin Barnet Adams, James Michael Hallaman, Roy James, Samuel Anil Choudhari, Danny Sheen, Barry S. Basile, Ronny Raborn

Patent number: 11262467Abstract: 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.Type: GrantFiled: April 17, 2019Date of Patent: March 1, 2022Assignee: Geospace Technologies CorporationInventors: Robbin Barnet Adams, James Michael Hallaman, Roy James, Samuel Anil Choudhari, Danny Sheen, Barry S.

Patent number: 9255999Abstract: A recording system and method for conducting seismic surveys including cordless battery-operated digital recorders, each employing an integral global positioning system receiver that is only periodically enabled for the purpose of establishing synchronized acquisition clock signals among all the recorders. The satellite receiver adjustment cycle is varied depending on past acquisition clock accuracy and temperature changes. A time stamp is recorded with the digitized seismic data in non-volatile memory. The memory is sized to allow extended periods of operation. Each recorder preferably includes a low-power system timer that may be used as a timer to remotely turn on and off the recorders according to a pre-programmed schedule to conserve power when the system is not in use. Electronic components are idled or de-energized when not needed.Type: GrantFiled: January 27, 2014Date of Patent: February 9, 2016Assignee: Geospace Technologies, LPInventors: Robbin B. Adams, Bhasker Vajapeyam, Jesus Eduardo Prado, Paul E. Carroll, James Michael Hallaman
