    摘要： Aspects of the technology described herein relate to methods and apparatuses for identifying gestures based on ultrasound data. Performing gesture recognition may include obtaining, with a wearable device, ultrasound data corresponding to an anatomical gesture; and identifying the anatomical gesture based on the obtained ultrasound data. Interfacing with a computing device may include identifying, with a wearable device, an anatomical gesture using ultrasound data obtained by the wearable device; and causing the computing device to perform a specific function based on the anatomical gesture identified by the wearable device. Training a wearable device to perform gesture recognition may include obtaining, with the wearable device, ultrasound data corresponding to an anatomical gesture; obtaining non-ultrasound data corresponding to the anatomical gesture; and training a machine learning model accessed by the wearable device to recognize the anatomical gesture based on correlating the non-ultrasound data and the ultrasound data.

    摘要： Circuitry for ultrasound devices is described. A multi-level pulser is described, which can support time-domain and spatial apodization. The multi-level pulser may be controlled through a software-defined waveform generator. In response to the execution of a computer code, the waveform generator may access master segments from a memory, and generate a stream of packets directed to pulsing circuits. The stream of packets may be serialized. A plurality of decoding circuits may modulate the streams of packets to obtain spatial apodization.

    摘要： Methods and apparatuses are provided for photoacoustic imaging. One such apparatus may include an ultrasound-on-a-chip device attached to a housing, an optical emitter attached to the housing, and a controller enclosed at least partially in the housing. The ultrasound-on-a-chip device may include a plurality of ultrasonic transducers. The optical emitter may include an array of diodes arranged at a periphery of the plurality of ultrasonic transducers. The controller may be configured to control the optical emitter to emit pulses of light, to control the plurality of ultrasonic transducers to detect ultrasonic waves emitted from a target to be imaged in response to exposure to the pulses of light, and to convert the ultrasonic waves to digital signals. For example, the optical emitter may be controlled to emit chirped optical pulses. The digital signals may be processed by the controller to produce image-formation data.
