Abstract: An apparatus may include a platen, a light source system and an ultrasonic receiver system. The platen may be configured to separate one or more received arterial ultrasonic waves generated by blood in an artery, by an arterial wall, or by a combination thereof, from one or more other types of received ultrasonic waves. The platen may have an outer surface with an acoustic impedance that is configured to approximate the acoustic impedance of human skin. The outer surface of the platen may be configured to conform to a surface of the human skin. The apparatus may include a noise reduction system. The light source system may include at least one multi-junction laser diode. The apparatus may include a mirror layer residing between the ultrasonic receiver system and the platen.

Abstract: Some disclosed methods involve controlling, via a control system, a light source system to emit a plurality of light pulses into biological tissue at a pulse repetition frequency, the biological tissue including blood and blood vessels at depths within the biological tissue. Such methods may involve receiving, by the control system, signals from the piezoelectric receiver corresponding to acoustic waves emitted from portions of the biological tissue, the acoustic waves corresponding to photoacoustic emissions from the blood and the blood vessels caused by the plurality of light pulses. Such methods may involve detecting, by the control system, heart rate waveforms in the signals, determining, by the control system, a first subset of detected heart rate waveforms corresponding to vein heart rate waveforms and determining, by the control system, a second subset of detected heart rate waveforms corresponding to artery heart rate waveforms.

Abstract: A system and method for ultrasonic sensing, wherein an ultrasonic receiver array includes multiple ultrasonic sensor pixels, and each sensor pixel includes an ultrasonic receiver configured to read an ultrasonic signal. An ultrasonic transmitter array, composed of multiple elements, transmits ultrasonic signals which may be reflected from an object and received at the ultrasonic receivers, wherein a sensor controller applies excitation signals to the transmitter array with a temporal delay between excitation signals.

Abstract: Some disclosed examples involve directing two or more pulse groups of light towards a target object during a total light transmission time interval, each pulse group time interval within the total light transmission time interval being separated from a successive pulse group time interval by an off time interval. The target object may be part of a human body or an animal body. In some examples, no light is transmitted towards the target object during the off time interval. Some disclosed examples involve receiving acoustic signals corresponding to photoacoustic (PA) responses of a target object to the two or more pulse groups and determining one or more heart rate waveforms of the human or animal body based on the acoustic signals.
