摘要： An ultrasonic transducer includes a membrane, a bottom electrode, and a plurality of cavities disposed between the membrane and the bottom electrode, each of the plurality of cavities corresponding to an individual transducer cell. Portions of the bottom electrode corresponding to each individual transducer cell are electrically isolated from one another. Each portion of the bottom electrode corresponds to each individual transducer that cell further includes a first bottom electrode portion and a second bottom electrode portion, the first and second bottom electrode portions electrically isolated from one another.

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： An ultrasound circuit comprising a trans-impedance amplifier (TIA) with built-in time gain compensation functionality 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, in some cases, followed by further analog and digital processing circuitry.

摘要： Aspects of the technology described herein related to monitoring fetal heartbeat and uterine contraction signals. An ultrasound system may be configured to sweep a volume to collect ultrasound data, detect a fetal heartbeat and/or uterine contraction signal in the ultrasound data, and automatically steer an ultrasound beam to monitor the fetal heartbeat and/or uterine contraction signal. The ultrasound system may be further configured to determine a location where the fetal heartbeat and/or uterine contraction signal is detectable or detectable at a highest quality. The ultrasound system may include a wearable ultrasound device, such as an ultrasound patch coupled to a subject. The wearable ultrasound device may have a two-dimensional array of ultrasonic transducers capable of steering ultrasound beams in three dimensions.

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： Described herein is an apparatus and method for attaching an ultrasound imaging device to a user. The apparatus includes a holster with a cradle for receiving at least a portion of the imaging device and a strap attachable to the cradle to secure the probe in the holster. In some embodiments, the strap extends diagonally across a portion of the imaging device when the imaging device is the holster. The strap may be formed of a flexible material while the cradle is formed of a rigid material. A width of the strap may decrease in an outwardly direction, from a first end of the strap to a second end of the strap.

摘要： Aspects of the technology described herein relate to detecting motion during collection of ultrasound data. Some embodiments include automatically comparing first ultrasound data collected from a set of locations at a first time and second ultrasound data collected from the set of locations at a second time to determine that a difference between the first and second ultrasound data exceeds a threshold difference. The set of locations may be scanline. Some embodiments include determining based on motion data from a motion sensor on the ultrasound device that an amount of motion exceeds a threshold amount of motion. An action may be performed based on determining that the difference between the first and second ultrasound data exceeds the threshold difference and/or that the amount of motion exceeds the threshold amount of motion. For example, the ultrasound data collection may be aborted, restarted, or a notification about motion may be generated.

摘要： Processes for fabricating capacitive micromachined ultrasonic transducers (CMUTs) are described, as are CMUTs of various doping configurations. An insulating layer separating conductive layers of a CMUT may be formed by forming the layer on a lightly doped epitaxial semiconductor layer. Dopants may be diffused from a semiconductor substrate into the epitaxial semiconductor layer, without diffusing into the insulating layer. CMUTs with different configurations of N-type and P-type doping are also described.

摘要： Complementary metal oxide semiconductor (CMOS) ultrasonic transducers (CUTs) and methods for forming CUTs are described. The CUTs may include monolithically integrated ultrasonic transducers and integrated circuits for operating in connection with the transducers. The CUTs may be used in ultrasound devices such as ultrasound imaging devices and/or high intensity focused ultrasound (HIFU) devices.
