The present technology relates to a display device, a display method, and an ultrasonic diagnostic system capable of providing a realistic ultrasonic diagnostic result. An image corresponding to an image signal obtained from an output signal of an ultrasonic diagnostic device is displayed on a display panel. Moreover, the display panel is vibrated according to a sound vibration signal obtained from the output signal by an actuator disposed on a back surface side of the display panel, whereby sound that is audibly sensed and vibration that is tactilely sensed are output on the display panel. The present technology can be applied to, for example, the ultrasonic diagnostic system or the like that performs inspection using ultrasonic waves.

The present invention relates to a method and system for determining a central pulse wave velocity in a pregnant woman. The method comprises receiving an indication of a measurement of a length of a human aortic path outside the body to provide an aortic length, arranging a sound transducer at the position of the anatomical projection of the uterine artery, identifying the opening of the maternal aortic valve with measurement from the sound transducer as a first time, and the pulse wave arrival time at the uterine artery with measurements from the sound transducer as a second time, determining the central transit time based on the difference between the second time and the first time, and calculating the central pulse wave velocity based on the aortic length and the central transit time.

An ultrasonic fingerprint sensor in a mobile device is operated to capture an initial snapshot of reflection from a finger's surface, of acoustic energy transmitted at a first frequency. Additionally, the ultrasonic fingerprint sensor is operated repeatedly to capture over time, a sequence of sets, each set including one or more additional snapshots of reflection from one or more depths within the finger, of acoustic energy transmitted at a second frequency significantly lower than the first frequency. Measurements in the additional snapshots are processed to determine whether any signal oscillating at a rate in a normal range for heart rate or respiration rate is present. When a signal is found, its rate may be used in several ways, e.g. to enable functionality when a fingerprint in the initial snapshot matches a reference fingerprint, or to identify and track a heart rate (or a respiration rate) based on the signal's rate.

The present disclosure describes systems, methods, and devices to infer changes in pulmonary artery pressure in a subject using Doppler radar. A portable, non-invasive device for non-invasively measuring right ventricular cardiac motion that can be used in a subject's home can infer pulmonary artery pressure changes to increase patient compliance and mitigate the likelihood of heart decompensation. A mobile pulmonary artery pressure monitor can be especially useful to patients with congestive heart failure who are elderly, incapacitated, or do not have easy access to a clinic, doctor's office, or hospital.
