Sonic Wave Transmitter Or Receiver Transducer Patents (Class 73/632)
  • Patent number: 10948457
    Abstract: Ultrasonic transmitting elements in an electroacoustical transceiver transmit acoustic energy to an electroacoustical transponder, which includes ultrasonic receiving elements to convert the acoustic energy into electrical power for the purposes of powering one or more sensors that are electrically coupled to the electroacoustical transponder. The electroacoustical transponder transmits data collected by the sensor(s) back to the electroacoustical transceiver wirelessly, such as through impedance modulation or electromagnetic waves. A feedback control loop can be used to adjust system parameters so that the electroacoustical transponder operates at an impedance minimum. An implementation of the system can be used to collect data in a vehicle, such as the tire air pressure. Another implementation of the system can be used to collect data in remote locations, such as in pipes, enclosures, in wells, or in bodies of water.

  • Patent number: 9372175
    Abstract: An active ultrasonic room occupancy sensor with the output amplitude of the transmitter controlled by the amplitude of power applied to the transmitter to control the zone of coverage for a sensor. An adjustable voltage regulator under control of a microcontroller applies controlled amplitude voltage to the transmitter to adjust the output amplitude of the transmitter. The adjustable amplitude transmitter allows an occupancy sensor to have its total output energy adjusted to conform to the area to be covered. Lowering the total ultrasonic energy in the monitored space lowers the sensitivity of the receiver to inappropriate activations. Lowering the input power to the transmitter also lowers the total internal system noise and provides an improved signal to noise ratio in the receiver. Alternatively, the power applied to the receiver may also be controlled by an adjustable voltage regulator under control of the microcontroller to improve receiver efficiency.

The method may be performed during laying of gas/oil fatigue sensitive pipelines, for example, at sea. Two types of UT inspection may be generated simultaneously by a Phased Array on each side (Upstream and Downstream) of a girth weld. Firstly, mode converted longitudinal waves are used. These waves have properties that they propagate well. Shear waves are also used. The combination of these two ultrasonic waves, with the addition of surface waves, enables 100% of the girth weld to be inspected to the standard required in fatigue sensitive welds, such as Steel Catenary Risers. Shear waves and compression waves are emitted substantially contemporaneously. Defects may be detected and measured using time of flight information and amplitudes of radiation detected on reflection and on diffraction from the defect.

  • Patent number: 8978478
    Abstract: A laser beam having a single wavelength emitted from a laser light source is converted at a wavelength shifter into a laser beam having at least two wavelengths, which is further demultiplexed at a beam splitter into a laser beam having a first wavelength and a laser beam having a second wavelength. The output power and pulse width of the laser beam having the first wavelength are adjusted by a first controller so as to reach levels appropriate for generating ultrasonic vibrations without causing damage to an inspection object. The output power and pulse width of the laser beam having the second wavelength are adjusted by a second controller so as to reach appropriate levels for detecting the above-described ultrasonic vibrations. These laser beams are multiplexed by a multiplexer into a single laser beam to be focused onto a surface of the inspection object.

  • Publication number: 20150053015
    Abstract: A multi-sensor NDI probe having means for self-alignment of the NDI sensors in conjunction with the movement of the sensor suite along the length of a hollow elongated stiffener having a rounded cap. The apparatus comprises a large-radius curved ultrasonic transducer array with cylindrical focus, which provides complete coverage for the rounded cap, two small-radius convex curved transducer arrays for NDI of the lower outside radii, and two linear transducer arrays for NDI of the sides of the stiffener. The five transducer arrays are supported by respective compliant assemblies which facilitate proper adjustment of the location (i.e., position and orientation) of the transducer arrays during scanning. The positions of the transducer arrays are adjusted to account for geometric variations in the stiffener.

  • Publication number: 20150037053
    Abstract: A protection member is arranged such that the distance from an opening plane of a reception guide to the center of the protection member is half of the distance from the opening plane of the reception guide to the surface of a reception vibration member. In other words, the arrangement position of the protection member is in the center between the opening plane of the reception guide and the surface of the reception vibration member. Accordingly, even if a protection member is arranged, a transmission coefficient is obtained that is equal to a transmission coefficient in the case where no protection member is present.

  • Publication number: 20150013464
    Abstract: An active ultrasonic room occupancy sensor with the output amplitude of the transmitter controlled by the amplitude of power applied to the transmitter to control the zone of coverage for a sensor. An adjustable voltage regulator under control of a microcontroller applies controlled amplitude voltage to the transmitter to adjust the output amplitude of the transmitter. The adjustable amplitude transmitter allows an occupancy sensor to have its total output energy adjusted to conform to the area to be covered. Lowering the total ultrasonic energy in the monitored space lowers the sensitivity of the receiver to inappropriate activations. Lowering the input power to the transmitter also lowers the total internal system noise and provides an improved signal to noise ratio in the receiver. Alternatively, the power applied to the receiver may also be controlled by an adjustable voltage regulator under control of the microcontroller to improve receiver efficiency.
