Abstract: Some disclosed examples involve receiving ultrasonic receiver signals from an ultrasonic receiver system corresponding to ultrasonic waves generated by a target object responsive to light from a light source system, estimating one or more blood vessel features based, at least in part, on the ultrasonic receiver signals and estimating blood pressure based, at least in part, on the one or more blood vessel features. Some disclosed examples involve receiving inertial sensor data from an inertial sensor system, determining whether the inertial sensor data indicates apparatus motion that exceeds a threshold and controlling a photoacoustic plethysmography (PAPG) system that includes the light source system and the ultrasonic receiver system according to whether the apparatus motion exceeds the threshold.

Abstract: An apparatus may include a platen, a light source system, an ultrasonic receiver system and a control system, the light source system configured for providing first light of a first wavelength and second light of a second wavelength to a target object on an outer surface of the platen. The control system may be configured to: cause the light source system to provide the first light to the target object at a first time and to provide the second light to the target object at a second time; receive first ultrasonic receiver signals and second ultrasonic receiver signals from the ultrasonic receiver system corresponding to photoacoustic responses of the target object to the first light and the second light, respectively; and estimate one or more blood vessel features based on at least one of the first ultrasonic receiver signals or the second ultrasonic receiver signals.

Abstract: An apparatus may include a platen, a light source system and a receiver system. The light source system may at least a first light-emitting component and at least a first light guide component. The first light guide component may be configured to transmit light from the first light-emitting component towards a target object in contact with a first area of the platen. The receiver system may include at least two receiver stack portions. A first receiver stack portion may reside proximate a first side of a first portion of the first light guide component and a second receiver stack portion may reside proximate a second side of the first portion of the first light guide component. The receiver system may be configured to detect acoustic waves corresponding to a photoacoustic response of the target object to light emitted by the light source system.

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 devices include a light source system, a target detection system; and a control system configured to communicate with the light source system and the target detection system. The control system may be further configured to receive target detection data from the target detection system, to estimate the presence or absence of a biological target based, at least in part, on the target detection data and to enable or disable the light source system based, at least in part, on an estimation of the presence or absence of the biological target. For example, if the biological target is detected, the control system may enable the light source system.
