Abstract: An apparatus may be configured to control a light source system residing in or on a first support structure portion of the apparatus to transmit light through an ear volume residing between a first ear portion and a second ear portion. The apparatus may be configured to receive, from a receiver system residing in or on a second support structure portion of the apparatus proximate the second ear portion, receiver system signals corresponding to acoustic waves caused by a photoacoustic response to light emitted by the light source system of a) a blood vessel residing within the ear volume, b) blood within the blood vessel, or a combination thereof. The control system may be configured to estimate one or more cardiac features based, at least in part, on the receiver system signals.

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: An apparatus may include a platen, a light source system and an ultrasonic receiver system. The light source system may be configured to provide light to a target object on an outer surface of the platen. The light source system may be configured to direct the light along a first axis oriented at a first angle relative to the outer surface of the platen. The ultrasonic receiver system may be configured to receive ultrasonic waves generated by the target object responsive to the light from the light source system. The ultrasonic receiver system may include one or more receiver elements residing in a receiver plane. A normal to the receiver plane being may be oriented along a second axis at a second angle relative to the outer surface of the platen. The first angle may be different from the second angle.

Abstract: Some disclosed examples involve obtaining, via a sensor system of a wearable device, first heart rate waveforms at a first wearable device configuration corresponding with a first position at least a portion of the sensor system. Some examples involve prompting, via a user interface of the wearable device, a user to change the wearable device configuration to a second wearable device configuration, the second wearable device configuration corresponding with a second position of one or more sensors of the sensor system. Some examples involve obtaining second heart rate waveforms at the second wearable device configuration and determining, based at least in part on the first heart rate waveforms and the second heart rate waveforms, whether to change a wearable device configuration or maintain a current wearable device configuration. Some examples involve prompting the user either to change the wearable device configuration or maintain the current wearable device configuration.

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: 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.

Abstract: An apparatus and associated method may include a light source system that includes a light-emitting component, and a receiver system configured to detect an acoustic wave that corresponds to a photoacoustic response of a blood vessel to light emitted by the light source system. A control system may be configured to determine a wave characteristic from the acoustic wave and to estimate a tensive state classification based on the determined wave characteristic. The tensive state classification may be one of a plurality of tensive state classifications that each include different ranges of diastolic and systolic values.
