  • Patent number: 10139504
    Abstract: An acoustic sound source designed to impart vibratory energy into its surrounding environment by linearly displacing transducer face plate(s) that are coupled to a rotary motor via crankshaft/connecting rod(s) or camshaft(s). The frequency of the vibrational energy is proportional to the speed of the rotary motor and the amplitude of the vibrational energy is proportional to the linear displacement of the transducer faceplates. The motor can be manually or automatically controlled to operate at a fixed speed and/or a variety of time varying speeds such as frequency sweeps or ramps. The linear displacement or amplitude of the transducer faceplates can also be manually or automatically controlled to operate at a fixed displacement or to have the displacement vary with time and/or frequency.

  • Patent number: 9441433
    Abstract: A remotely actuated clamping device for a borehole seismic sensing system. The remotely actuated clamping device includes a clamping mechanism configured to engage a surface of a borehole by actuation of the clamping mechanism. The remotely actuated clamping device also includes a fluid based actuator configured to actuate the clamping mechanism. The fluid based actuator includes a chamber configured to be kept at a pressure that is isolated from an ambient pressure of the borehole. The fluid based actuator also includes a piston within the chamber. The chamber receives a pressurized fluid to move the piston within the chamber to actuate the clamping mechanism. The pressure used to actuate the clamping mechanism is independent of the ambient pressure of the borehole. Also disclosed are methods of operating the device.

  • Publication number: 20120216615
    Abstract: A method of measuring acceleration using an optical sensor. In the optical sensor, acceleration, acoustic velocity, or displacement (vibration) causes a corresponding shift in the center wavelength of the sensor output. The sensor can be coupled to a high-speed interferometric interrogator through an unbalanced fiber interferometer. The unbalanced interferometer functions to translate optical wavelength shift into phase shift, which is easily demodulated by the interrogator.

  • Patent number: 6262944
    Abstract: An acoustic array including a plurality of acoustic sensors positioned at predetermined telemetry points for measuring the acoustic energy from the surrounding environment. The acoustic sensors are each positioned within a fluid-filled pocket in the acoustic array, wherein each the various fluid-filled pockets are separated from each other by a section of solid fill buoyant material. The sections of solid fill material control the buoyancy of the acoustic array. The acoustic array is surrounded by a longitudinally extending outer hosewall which encloses the acoustic array and forms the fluid-filled pockets between the sections of solid fill material. A strength member is extended longitudinally throughout the length of the acoustic array to provide a load bearing mechanism for distributing longitudinal tensile loads applied to the acoustic array, while support spacers are situated within the acoustic array to provide radial support for the acoustic array.
