  • Patent number: 11953639
    Abstract: Some aspects relate to techniques for calibrating a logging tool. In some implementations, the logging tool may estimate certain unknown properties of a signal based on distances between transmitters and receivers of the logging tool and based on frequencies used by the transmitters and receivers. The logging tool may estimate the unknown properties by interpolating values into a mathematical function related to the above-noted distances and frequencies. After estimating the unknown properties, the logging tool may be deployed into the wellbore, where it may use the estimated properties to process signals received through a subsurface formation.

  • Patent number: 11953640
    Abstract: The present invention is a pressure coupling chamber (1) developed for comparison calibrations of acoustic pressure-sensitive hydrophone (2) in the frequency range from Hz to 1 kHz. A hydrophone (2), reference receiver unit (3) and acoustic source (6) under test are acoustically coupled in the chamber through the air-filled medium inside the pressure coupling chamber (1). Acoustic sources (6) that are going to create acoustic pressure in the pressure coupling chamber (1), placed on the side walls of the chamber (1) to surround the pressure-sensitive active surface of hydrophone (2), are driven to create a hydrostatic pressure effect in the related frequency range in the chamber. Calibration of tested hydrophone (2) with comparison method is carried out by measuring the output voltages of tested hydrophone (2) and the reference receiver unit (3).

    Abstract: Systems and methods for determining a location of an object within a sonar beam zone are detailed herein. A system for presenting marine data includes at least one sonar transducer associated with a watercraft, a display, processor(s), and a memory including a computer program code. The sonar transducer emits sonar beams into an underwater environment defining a beam shape. The program code, when executed, causes, on the display, presentation of a chart and a representation of the watercraft; and determines, based on the beam shape corresponding to the sonar transducer, a sonar beam zone corresponding to a sonar coverage of the underwater environment of the body of water. The program code further receives sonar return data and determines a position of an object within the sonar beam zone, and causes, on the display, presentation of the sonar beam zone and an indication of the object within the sonar beam zone.

  • Patent number: 11933892
    Abstract: An ultrasound imaging system has an array of ultrasound transducers comprising a set of sub-arrays of transducers. Each transducer (100) has an analogue buffer (106). Each sub-array of transducers has a signal path (102, 104) from within the array of ultrasound transducers to outside the array of ultrasound transducers which comprises one or more hops between the buffers (106). To reduce the signal line length from inside the array of ultrasound transducers to the periphery, at least some multiple hops between buffers (106) are provided. Each buffer hop introduces a delay, but prevents signal degradation so that a large number of analog signals can be transmitted across the large area ASIC of the transducer array.

  • Patent number: 11933891
    Abstract: Target value detection for an unmanned aerial vehicle is described. The unmanned aerial vehicle includes a first transducer that transmits a first ultrasonic signal and receives a first ultrasonic response and a second transducer that transmits a second ultrasonic signal and receives a second ultrasonic response. The second transducer has a wider beam pattern than the first transducer. Determinations are made as to whether either or both of the first or second ultrasonic responses includes a target value within range areas associated with the respective beam patterns of the first and second transducers. A confidence value is generated based on the determinations. The target value is reflected from an object and the confidence value indicates a likelihood of a position of the unmanned aerial vehicle with respect to the object.

  • Patent number: 11921214
    Abstract: A method transmits a first optical beam towards targets within a field of view (FOV). The first optical beam is modulated at a first chirp rate for a first set of scan lines that correspond to a first distance of the targets. The method identifies conditions based on the FOV to calculate a second chirp rate, and generates a scan pattern by transmitting a second optical beam towards the targets within the FOV. The second optical beam is modulated at the second chirp rate for a second set of scan lines that corresponds to a second distance of the one or more targets. The method generates, based on the first and second optical beams, the point cloud that includes multiple data points related to the target in which some of the data points are related to a first target and other data points are related to a second target.
