  • Patent number: 11982721
    Abstract: Apparatus and associated methods relate to detecting leakage current in a powered electrical system. Leakage current is detected by comparing a high-frequency response signal with a high-frequency reference signal. A high-frequency excitation signal is coupled, via an inducer, into the powered electrical system at a first location. The high-frequency response signal is sensed, via a signal sensor, at a second location of the powered electrical system. Because the electrical dynamics of the powered electrical system can change in response to system degradation that results in leakage current, changes in the high-frequency response signal can be indicative of leakage. Thus, the high-frequency response signal is compared, by a controller, with a high-frequency reference signal. The high-frequency reference signal can be a high-frequency response signal obtained at a reference time, at which the powered electrical system is operating without leakage.

  • Patent number: 11982737
    Abstract: Techniques for presence-detection devices to vary presence-detection sensitivity to detect different types of movements by objects, such as major movements and minor movements, using ultrasonic signals. The devices detect movement of a person in an environment by emitting ultrasonic signals into the 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 relative to the presence-detection devices. The presence-detection devices may control the presence-detection sensitivity in order to detect major movements, such as a user walking in a room, as well as objects minor movements, such as a user typing at a computer. By adjusting the presence-detection sensitivity, the devices are able to improve the overall accuracy of detecting the presence of users in an environment.

  • Patent number: 11982738
    Abstract: A system and method for determining the position and orientation of a wearable audio device, for example, methods and systems for determining the position, orientation, and/or height of a wearable audio device using acoustic beacons. In some examples, the determined position, orientation, and/or height can be utilized to correct for drift experienced by an inertial measurement unit (IMU). In other examples, the drift may cause am externalized or virtualize audio source, generated within a known environment, to move or drift relative to the known locations of physical audio sources within the environment. Thus, the systems and methods described herein can be utilized to correct for drift in the position of a virtual audio source with respect to the wearable audio device by first determining its own absolute position and orientation within the environment.

  • Patent number: 11982739
    Abstract: Ultrasonic ranging state management for a UAV is described. A transducer transmits an ultrasonic signal and receives an ultrasonic response thereto using a gain value. A noise floor estimation mechanism determines a noise floor estimate. A state mechanism sets an ultrasonic ranging state used by the transducer to a first ultrasonic ranging state. The transducer transmits an ultrasonic signal and responsively receive an ultrasonic response to the ultrasonic signal using a gain value according to the noise floor estimate. The state mechanism processes the ultrasonic response to determine whether to determine a new noise floor estimate, adjust the gain value used by the transducer, or change the ultrasonic ranging state of the UAV to a second ultrasonic ranging state. The configurations of the first and second ultrasonic ranging states differ as to, for example, power and gain levels used by the transducer to receive ultrasonic responses.

  • Patent number: 11982741
    Abstract: The invention provides methods and systems for generating an ultrasound image. In a method, the generation of an ultrasound image comprises: obtaining channel data, the channel data defining a set of imaged points; for each imaged point: isolating the channel data; performing a spectral estimation on the isolated channel data; and selectively attenuating the spectral estimation channel data, thereby generating filtered channel data; and summing the filtered channel data, thereby forming a filtered ultrasound image. In some examples, the method comprises aperture extrapolation. The aperture extrapolation improves the lateral resolution of the ultrasound image. In other examples, the method comprises transmit extrapolation. The transmit extrapolation improves the contrast of the image. In addition, the transmit extrapolation improves the frame rate and reduces the motion artifacts in the ultrasound image. In further examples, the aperture and transmit extrapolations may be combined.

  • Patent number: 11982749
    Abstract: This document describes a time-of-flight lidar system configured to process pulse trains instead of individual pulses, for improved range resolution and pixel throughput. Each pulse in the pulse train is output at a respective duration and intensity, which may vary to provoke a return with a high-intensity and low signal ambiguity, prevent thermal build-up, or promote safe ocular operation. An expected intensity of the return as a function of time can be determined. By sampling reflections at the expected times and intensities, the lidar system quickly identifies a corresponding lidar return, even despite lidar noise. A return time of the return can indicate a distance or speed associated with an object pixel in a field-of-view. Processing pulse trains instead of individual pulses allows pixels to be scanned faster than using long durations or frame times, which also promotes ocular safety. Increased throughput is realized using low-energy lasers and inexpensive hardware, which minimize thermal footprint.
