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： Aspects of the technology described herein relate to an ultrasound device including a first die that includes an ultrasonic transducer, a first application-specific integrated circuit (ASIC) that is bonded to the first die and includes a pulser, and a second ASIC in communication with the second ASIC that includes integrated digital receive circuitry. In some embodiments, the first ASIC may be bonded to the second ASIC and the second ASIC may include analog processing circuitry and an analog-to-digital converter. In such embodiments, the second ASIC may include a through-silicon via (TSV) facilitating communication between the first ASIC and the second ASIC. In some embodiments, SERDES circuitry facilitates communication between the first ASIC and the second ASIC and the first ASIC includes analog processing circuitry and an analog-to-digital converter. In some embodiments, the technology node of the first ASIC is different from the technology node of the second ASIC.

摘要： Aspects of the technology described herein relate to ultrasound circuits that employ a differential ultrasonic transducer element, such as a differential micromachined ultrasonic transducer (MUT) element. The differential ultrasonic transducer element may be coupled to an integrated circuit that is configured to operate the differential ultrasonic transducer element in one or more modes of operation, such as a differential receive mode, a differential transmit mode, a single-ended receive mode, and a single-ended transmit mode.

摘要： An ultrasound circuit comprising a multi-stage trans-impedance amplifier (TIA) is described. The TIA is coupled to an ultrasonic transducer to amplify an electrical signal generated by the ultrasonic transducer in response to receiving an ultrasound signal. The TIA may include multiple stages, at least two of which operate with different supply voltages. The TIA may be followed by further processing circuitry configured to filter, amplify, and digitize the signal produced by the TIA.

摘要： An electronic device with an ability to perform touch detection includes an ultrasound touch sensor disposed within a housing and configured to detect physical contact with an exterior surface of the housing. The sensor may emit ultrasonic sound waves, receive reflected ultrasonic sound waves reflected from a surface portion corresponding to the physical contact at the exterior surface of the housing, and compare the reflected ultrasonic sound waves to a stored reflection pattern. Based on determining a match between the reflected ultrasonic sound waves and the stored reflection pattern, the electronic device may activate a function. The sensor may be part of an ultrasound-on-a-chip device.
