  • LAND BASED UNIT FOR SEISMIC DATA ACQUISITION
    Publication number: 20170299740
    Abstract: In one aspect, a seismic data acquisition unit is disclosed including a closed housing containing: a seismic sensor; a processor operatively coupled to the seismic sensor; a memory operatively coupled to the processor to record seismic data from the sensor; and a power source configured to power the sensor, processor and memory. The sensor, processor, memory and power source are configured to be assemble as an operable unit in the absence of the closed housing.
    Type: Application

  • Accelerometer transducer used for seismic recording
    Patent number: 6883638
    Abstract: Method for operating and testing a sensor assembly (210). The sensor assembly (210) preferably includes accelerometers with axes of sensitivity orthogonal to each other. The method preferably includes determining sensor tilt angle, determining the position of the sensor, and synchronizing the operation of the sensor.

  • Two-conductor bidirectional digital seismic telemetry interface
    Patent number: 6529443
    Abstract: A two-conductor bidirectional digital telemetry interface between a seismic sensor acquisition/conversion module and a seismic data collection module. The data collection module is configured as a master electronics device and the sensor acquisition/conversion module is configured as a slave electronics device in the telemetry system. The master device provides power to the slave device over the two conductors. The master device transmits portions of commands to the slave device at a first time and the slave device transmits portions of a digital seismic data packet to the master at a different second time in a fixed-duration frame. The frames are transmitted at regular intervals. The outbound commands and inbound data are encoded by block codes. A phase-locked loop in the slave is locked to a master clock in the master by deriving a clock and a sync point from the block-coded commands it receives from the master.
