An ultrasonic sensing apparatus held next to a target can detect vital signs of the target. The ultrasonic sensing apparatus includes a first flexible circuit board, a transmitting layer, a readout layer, and a receiving layer. Emitting elements in the transmitting layer generate ultrasonic signals and the receiving layer receives reflected ultrasonic signals and converts the reflections into electrical signals. The emitting elements are staggered in relation to elements of the receiving layer for better resolution and accuracy. The readout layer reads the electric signals for calculating vital signs. The readout layer includes input lines and output lines and readout pixels are defined by the crossing points of input and output lines. Ultrasonic signals are generated during a first period, and the reflections are read in a second period next following. The readout layer completes one reading operation corresponding to one readout pixel during the second period.

Aspects of the technology described herein relate to techniques for guiding an operator to use an ultrasound device. Thereby, operators with little or no experience operating ultrasound devices may capture medically relevant ultrasound images and/or interpret the contents of the obtained ultrasound images. For example, some of the techniques disclosed herein may be used to identify a particular anatomical view of a subject to image with an ultrasound device, guide an operator of the ultrasound device to capture an ultrasound image of the subject that contains the particular anatomical view, and/or analyze the captured ultrasound image to identify medical information about the subject.

A portable electronic device for assessing a human cardiovascular activity includes first and second probes substantially parallel to each other and located on either side of a third probe, substantially perpendicular to the first and second probes, each probe comprising an array of ultrasound transducers, and a control circuit configured to: a) estimate, by means of a first ultrasound beam emitted by the first probe, a position of a blood vessel with respect to the device; and b) adjust a second ultrasound beam, emitted by the third probe, according to the estimated position of the blood vessel.

A structure formed with a frame structure and a sheet of material configured to reduce sound is wrapped around or otherwise surrounds the frame structure to form a hammock, basket, meditation pod, animal bed, snore reduction unit, wearable enclosure or other small structure, with an inner, sound limited or reduced volume. The sheet of material includes a base layer and at least one layer of sound-absorbing material, at least one layer of sound barrier material, or both, provided on or integral with the base layer. The sound limited or reduced volume includes an opening that may be closed or partially closed with a flap, canopy or hood. The flap, canopy or hood is preferably made of the same material at the sheet of material surrounding the frame.

A medical diagnostic method, system and related equipment particularly adapted to diagnose disorders of the blood circulation serving the head and neck, and especially the brain. A preferred use of the system is early, rapid, accurate, diagnosis of stroke, especially whether the stroke is due to blockage of a blood vessel or leakage from the blood vessel.

Systems/techniques that facilitate two-tiered machine learning generation of birth risk score are provided. In various embodiments, a system can access a plurality of medical feature collections associated with a pregnant patient. In various aspects, the system can generate, via execution of a plurality of first trained machine learning models, a plurality of embedded features based on the plurality of medical feature collections.
