Abstract: Some disclosed examples involve controlling a light-steering system to direct light emitted by at least a first light source of a light source system to a first plurality of areas of a target object, wherein controlling the light-steering system involves controlling one or more adjustable micromirrors, one or more adjustable lenses, one or more adjustable diffraction gratings, or combinations thereof. Some examples involve receiving ultrasonic receiver signals from an ultrasonic receiver system corresponding to photoacoustic responses of the target object to light provided the light source system to each area of the first plurality of areas and determining a selected area of the target object from which additional ultrasonic receiver signals will be obtained, wherein determining the selected area involves detecting a blood vessel within the target object. Some examples involve controlling the light source system to obtain additional ultrasonic receiver signals from the selected area.

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: Sensors and systems for determining a physiological parameter such as blood pressure using external pressure are disclosed. Such sensors and/or systems may be embodied in a wearable user device. The wearable user device may include a cuff configured to apply a pressure to a portion of a user at one or more substantially constant pressure levels; a photoacoustic sensor configured to obtain photoacoustic signals generated from light incident on a blood vessel; and a wearable structure including the cuff and the photoacoustic sensor. Techniques involving the wearable user device may include: obtaining photoacoustic signals from a portion of the user; determining a curve associated with the user, the curve including a plurality of spatial measurements of the blood vessel as a function of a plurality of discrete pressures, the curve enabling determination of a characteristic of the blood vessel; and determining the physiological parameter based at least on the characteristic.

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.
