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: Some disclosed examples pertain to an apparatus that can include a platen, a light source system, a receiver system, and an electromagnetic interference (EMI) shield. The light source system can include light source system circuitry, a light-emitting component, and a light guide component having a substantially uniform cross-section. The light-emitting component provides light to an area of the platen via the light guide component. The receiver system can include at least two receiver stack portions residing proximate on either side of the light guide component. The receiver system detects acoustic waves corresponding to a photoacoustic response of a target object proximate the area of the platen, to light emitted by the light source system. The EMI shield shields the receiver system from at least some of the EMI produced by the light source system circuitry. The light guide component conveys light through a portion of the EMI shield.

Abstract: An apparatus and associated method of manufacture may include a receiver system that includes an array of receiver elements, in addition to receiver system circuitry. A least a portion of the array of receiver elements is transparent. The transparency allows light to pass through so that blood vessel behind may be visible or otherwise perceived. In this manner, the receiver system may detect (i.e., through the transparent portion of the receiver elements) acoustic waves corresponding to the blood vessel's photoacoustic response to light emitted by a light source system that includes a light-emitting component.
