Abstract: Aspects of the technology described herein relate to prolonging battery life in an electronic device, such as ultrasound devices. A system may include an ultrasound device and a package. The ultrasound device may include magnetic sensing circuitry. The package may include a lid, and the lid may include a magnet. The magnetic sensing circuitry may control power received by communication circuitry in the ultrasound device based on detecting a magnet that is external to the ultrasound device. For example, the magnetic sensing circuitry may disable power rails in the power circuitry that provide power to communication circuitry when the magnetic sensing circuitry detects the magnet. When the magnetic sensing circuitry cannot detect the magnet, the power circuitry may enter a default state in which power rails provide power to the communication circuitry. The ultrasound device may include an indicator that enters a turn-on sequence when the lid is removed from the package.

Abstract: Aspects of technology described herein relate to guiding collection of ultrasound data collection using motion and/or orientation data. A directional indicator corresponding to an instruction for moving an ultrasound imaging device relative to a subject may be displayed in an augmented reality display. The direction of the directional indicator in the augmented reality display may be independent of an orientation of the ultrasound imaging device. The augmented reality display may include video captured by a camera that depicts the ultrasound imaging device and a fiducial marker on the ultrasound imaging device. The direction of the directional indicator may be based on the pose of the camera relative to the fiducial marker and the rotation and/or tilt of the ultrasound imaging device relative to the axis of gravity. The direction of the directional indicator may also be based on the pose of the camera relative to the subject.

Abstract: 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.

Abstract: To implement a single-chip ultrasonic imaging solution, on-chip signal processing may be employed in the receive signal path to reduce data bandwidth and a high-speed serial data module may be used to move data for all received channels off-chip as digital data stream. The digitization of received signals on-chip allows advanced digital signal processing to be performed on-chip, and thus permits the full integration of an entire ultrasonic imaging system on a single semiconductor substrate. Various novel waveform generation techniques, transducer configuration and biasing methodologies, etc., are likewise disclosed. HIFU methods may additionally or alternatively be employed as a component of the “ultrasound-on-a-chip” solution disclosed herein.

Abstract: Aspects of the technology described herein relate to instructing a user to use an ultrasound device to collect ultrasound data. A local processing device may provide an instruction to collect sets of data from multiple positions of the ultrasound device relative to a subject. The local processing device may receive sets of data from the ultrasound device, each of the sets of data including ultrasound data collected at a particular position of the ultrasound device relative to the subject. The local processing device may transmit the sets of data to a remote processing device. The local processing device may receive, from the remote processing device, an indication of a selected set of data from among the sets of data. The local processing device may provide an instruction to move the ultrasound device to the position of the ultrasound device at which the selected set of data was collected.
