摘要： An ultrasound circuit comprising a single-ended 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 is followed by further processing circuitry configured to filter, amplify, and digitize the signal produced by the TIA.

摘要： An ultrasound device is describe in which analog ultrasonic transducer output signal are directly converted to digital signals. The ultrasound device includes microfabricated ultrasonic transducers directly coupled to a sigma delta analog-to-digital converter in some instances. The direct digital conversion may allow for omission of undesirable analog processing stages in the ultrasound circuitry chain. In some situations, the ADC may be integrated on the same substrate as the ultrasound transducer.

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.

摘要： Aspects of the technology described herein relate to configuring an ultrasound system with imaging parameter values. In particular, certain aspects relate to configuring an ultrasound system to produce a plurality of sets of ultrasound images, each respective set of the plurality of sets of ultrasound images being produced with a different respective set of a plurality of sets of imaging parameter values; obtaining, from the ultrasound system, the plurality of sets of ultrasound images; determining a set of ultrasound images from among the plurality of sets of ultrasound images that has a highest quality; and based on determining the set of ultrasound images from among the plurality of sets of ultrasound images that has the highest quality, automatically configuring the ultrasound system to produce ultrasound images using a set of imaging parameter values with which the set of ultrasound images that has the highest quality was produced.

摘要： Methods and apparatus for three-dimensional imaging of a sample. A source is provided of a beam of substantially collimated light characterized by a temporally dependent spectrum. The beam is focused in a plane characterized by a fixed displacement along the propagation axis of the beam, and scattered light from the sample is superposed with a reference beam derived from the substantially collimated source onto a focal plane detector array to provide an interference signal. A forward scattering model is derived relating measured data to structure of an object to allow solution of an inverse scattering problem based upon the interference signal so that a three-dimensional structure of the sample may be inferred in near real time.

摘要： An electronic face-identification device, which performs face scanning with ultrasonic waves, includes a housing and an ultrasound device disposed within the housing. The ultrasound device may be configured to transmit ultrasonic waves through air to a face and scan the face with the ultrasonic waves, to receive reflected waves through the air corresponding to reflections of the ultrasonic waves from the face, and to perform a recognition process for the face based on reflections of the ultrasonic waves from the face. The ultrasound device may include a plurality of ultrasound transducers, and electronic circuitry configured to transmit signals to the ultrasound transducers and receive signals from the ultrasound transducers. The face-identification device may be incorporated into various electronic equipment, such as hand-held equipment in the form of smartphones and tablet computers, as well as in larger scale installations at airports, workplace entryways, and the like.

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.
