Acoustic Image Conversion Patents (Class 367/7)
  • Patent number: 11402499
    Abstract: This disclosure describes presence-detection devices that detect movement of a person by emitting ultrasonic signals into an environment, and characterizing the change in the frequency, or the Doppler shift, of the reflections of the ultrasonic signals off the person caused by the movement of the person. The techniques include downsampling the audio signals from the carrier frequency range down to a frequency range with a center frequency around 0 Hz. A filter is applied to attenuate signals around 0 Hz and below (or above), such as the emitted signals. In addition to removing the emitted signals, the negative side (or positive side) of the audio signals are removed, but the Doppler shift is still represented in the remaining portion of the audio signals. By removing a portion of the audio signals, the amount of processing required to detect the Doppler shift in the reflections of the ultrasonic signals is reduced.

  • Patent number: 11147538
    Abstract: A method for computing a tissue reflectivity function (TRF) is provided. This method comprises accessing radio-frequency (RF) data and computing a point spread function (PSF), to obtain the TRF. The RF data accessed are data obtained by beamforming time signals from an array of transducers of an ultrasound device. Next, for each pair (r, s) of given pairs of points in the imaging plane, the PSF is computed as a sum of contributions from at least some of the transducers. Each contribution is computed by evaluating a transducer's transfer function, based on two outputs of a respective time-of-flight function. Such outputs are obtained by evaluating the time-of-flight function at a first point r and at a second point s of each pair, respectively. Finally, the RF function can be deconvoluted, based on the computed PSF, so as to obtain the TRF.

  • Patent number: 10078069
    Abstract: The inventive concept relates to a device that detects a leak of a liquid leaked from a sinkhole, water pipe or oil pipeline under the ground. In the detection device of the inventive concept, a plurality of reception devices disposed on the surface of the earth simultaneously receive an ultrasonic signal transmitted from a transmission device under the ground and a radio frequency (RF) signal synchronized with the ultrasonic signal. Also, by measuring an arrival time of the ultrasonic signal by using the wireless signal received by each reception device as a triggering signal, a leak range of a liquid leaked from a sinkhole, water pipe or oil pipeline on a signal path between the transmission device and the reception device is detected.

  • Patent number: 10064602
    Abstract: Acoustic reciprocity between transmit and receive is used for coherence ultrasound imaging. Rather than finding coherence across the receive channels, coherence is found across transmit channels. Broad transmit beams are used for different transmit elements or apertures to create beamformed frames of data. The coherence between these transmit channel frames of beamformed data is calculated and used for imaging.

  • Patent number: 10026182
    Abstract: Mechanisms for generating a true depth profile of a body of water are disclosed. A depth profile tensor that identifies a depth at each of a plurality of locations of the body of water is accessed. The depth profile tensor identifies, for at least some locations of the plurality of locations, multiple depths. The depth profile tensor is converted to a binary potential depth image that depicts multiple potential depths for the at least some locations. The multiple potential depths are reduced, by a morphological filter process, to a single depth for the at least some locations to generate a binary depth image. The binary depth image is converted to the true depth profile.

  • Patent number: 10001461
    Abstract: A crystal self-test circuit is used to self-test either an acoustic emission crystal or a vibration crystal installed onto one of a bearing, a bearing housing, and a machine. A crystal self-test circuit includes a multiplexer IC, which toggles between a pulse injection configuration and a signal collection configuration. In the pulse injection configuration, the multiplexer IC provides signal communication between a crystal self-test input and the sensing emission crystal. In the signal collection configuration, the multiplexer IC provides signal communication between the sensing emission crystal and a signal analyzer. In operation, the multiplexer IC applies a waveform (preferably a square wave) to the sensing emission crystal over a predetermined time period. The multiplexer IC then toggles to collect the output waveform from the sensing emission crystal and forwards the output waveform to the signal analyzer. The output signal can be amplified by a signal amplifier.

  • Patent number: 9927521
    Abstract: A method and a device for high frequency acoustic spectrum imaging for an object over a field of view. A camera captures an image of the object. A raster with grids is created as an overlay on the captured image. A directional microphone detects high frequency acoustic waves emanating from the object. An acoustic data signal corresponding to the high frequency acoustic waves is generated by a microphone data processing unit. The coordinates of the focal point of the directional microphone on the grid of the raster is recorded and sent as a real-time feedback position signal to a processor for each measurement of the acoustic signal data. The processor plots a visual representation of the acoustic signal data mapping it to the corresponding coordinates on the raster and creates a high frequency acoustic spectrum image for the object by superimposing the raster on the captured image.
