Echo Systems Patents (Class 367/87)
  • Patent number: 10861164
    Abstract: Natural frequencies of vibration of objects, such as aerial vehicles, are identified based on imaging data captured while the objects are subjected to excitation. The imaging data is captured using high-speed cameras, and changes in intensities of pixels corresponding to surfaces of the object are used to determine a spectral diagram of the vibrations from which natural frequencies of vibration (e.g., vibration modes) are determined. The visibility of the vibrating objects is enhanced by providing video images to band-pass filters within small bands around the natural frequencies, and magnifying the vibration based on the amplitudes or phases determined from each of the video images. A stream of the modified video images may be used to determine a mode shape corresponding to the vibration of the objects at or around a natural frequency of vibration.

  • Patent number: 10595742
    Abstract: A system and method for classifying body activities through an on-body antenna measuring changes in reflected power and the resulting reflection coefficients, in contrast to two antenna systems that measure transmission power therebetween. A single on-body antenna can be attached or held in close proximity to the body. The antenna can be calibrated based on changes in the reflection coefficients for various calibration activities for the location at which the antenna is placed on the body. Magnitude changes and patterns of the reflection coefficients at a given frequency for a given activity can be compared with calibrated data to correlate a given activity. Further accuracy can be gained by comparing both magnitude and phase changes and patterns at a given frequency with calibrated data for a given activity. The antenna can use power losses from a transmitted signal to measure the changes in the reflected power to minimize power requirements.

    Abstract: In an apparatus for multi-pole acoustic logging while drilling, a N-cycle sinusoidal wave signal is generated by utilizing a signal processor, and amplified into a high-voltage sinusoidal excitation signal by utilizing a power amplifier, and output to a transmitting transducer. The signal processor simultaneously generates an enable signal. The enable signal includes a transient discharge enable signal. The power amplifier is connected with a transient discharge circuit. After the signal processor generates N cycles of a sinusoidal wave, the transient discharge enable signal enables the transient discharge circuit to discharge to release an energy storage current of a power transformer so as to eliminate a high-voltage ringing effect and improve an excitation efficiency of the transducer.

  • Patent number: 10048372
    Abstract: To evaluate the resolution of individual sonar images in field conditions without specific targets, a statistical sampling of the imagery is taken and analyzed. Large quantities of resolution measurements are made on point-objects identified in the imagery. The measurements are compared to improve fidelity and generate statistically significant results. The image is broken into segments for analysis to identify variation in resolution across the image. The mean value of point-target resolution per segment can be determined for the imagery. A segment with an insufficient number of measurements required to determine a statistically significant value for resolution is rejected. The image resolution can be determined as the mean or median value of the segment measurements for the entire image.

  • Publication number: 20150138920
    Abstract: A system is provided that includes a gateway node and terminal node. The gateway node may be configured to produce a continuous acoustic wave for propagation through a fluid such as water, and detect an echo thereof. The terminal node may be configured to control a piezoelectric layer to switchably reflect or transmit the acoustic wave incident thereon to produce and modulate the echo with a data stream to thereby convey the data stream within the echo, which the sensor of the gateway node may detect. The terminal node may be further configured to capture and store energy produced by the piezoelectric layer while the piezoelectric layer is controlled to transmit the incident acoustic wave. And at least a portion of the terminal node may be powerable from the stored energy.

  • Patent number: 9030914
    Abstract: A method for imaging formations below the bottom of a body of water includes imparting acoustic energy into the formations along a predetermined length swath at a selected geodetic position. Acoustic energy reflected from the formations is detected along a line parallel to the length of the swath. The selected geodetic position is moved a selected distance transverse to the length of the swath. The imparting acoustic energy, detecting acoustic energy and moving the geodetic position are repeated until a selected distance transverse to the length of the swath is traversed. The detected acoustic energy from all the selected geodetic positions is coherently stacked. The detected acoustic energy is beam steered to each of a plurality of depths and positions along the length of the swath to generate an image for each such depth and position.

  • Publication number: 20150098304
    Abstract: Devices and methods for aiding a large area search for submerged objects such as aircraft. A searcher transmits interrogation signals to be received by a device at the target object. The interrogation signals have a long range relative to that of returned signals. The target device responds with a ping signal modified to be more easily found by means of information contained in the interrogation signal. The information may be inherent in the nature of the received signal or data encoded and embedded by the searching device. The target device may use a microprocessor to do complex operations using the information from the interrogation signal and other information. Detection of a weak ping is facilitated by such means as being beamed in the direction of the interrogation, arriving at a predictable time, or having parameters adapted to values requested by the searcher.

    Abstract: An apparatus and method for removing noise of an ultrasonic system to improve robustness against noise by removing external noise from a reception signal reflected from an object are provided. The method includes transmitting, by a sensor, a transmission signal to a medium and receiving a reception signal reflected from the medium. A controller is configured to remove noise from a frequency range recognized as a normal signal from the reception signal and calculate a correlation between the transmission signal and a signal in the frequency range recognized as the normal signal in the reception signal. In addition, the controller is configured to determine whether the signal in the frequency range recognized as the normal signal is the normal signal or noise based on the calculated correlation.

An acoustic transducer at a first cellular communication device is used to determine a gesture of a user object with respect to a first cellular communication device. The gesture is generally performed in a three-dimensional space of the first cellular communication device. A haptic signal is created that corresponds to the determined gesture and is sent from the first cellular communication device to a second cellular communication device. An actuator at the second cellular communication device is actuated according to the haptic signal to produce a haptic sensation at the second cellular communication device.

  • Publication number: 20150063060
    Abstract: A method for pre-determining an underwater objects GPS position using a rotatable scan sonar unit linked to a boat, magnetic compass and GPS receiver. This system determines the underwater objects GPS position using the objects distance, compass heading and a GPS receiver/sonar on a boat. This system will provide real time longitude and latitude positions of underwater objects seen with sonar at a distance from a boat, and will allow for precise autopilot navigation or fixed position fishing. The system can also be used to correct for GPS errors when using previously stored waypoints positions of an object. The computer determines an objects underwater GPS position using a sonar transducer and mounted on a 360 degree movable mechanism such as a trolling motor unit, or phased array of transducers and a compass to provide heading information and formulates the objects position based on the distance and heading of the object in relation to the boats current GPS position.
