    Abstract: Multi-sensor devices and systems are disclosed. A multi-sensor user device may include a first acoustic sensor and a second acoustic sensor disposed at a first distance from each other, the first and second acoustic sensors each configured to obtain respective first and second acoustic signals associated with a blood vessel of a user; a first motion sensor and a second motion sensor disposed at a second distance from each other, the first and second motion sensors each configured to obtain respective first and second motion signals associated with the blood vessel; a photoacoustic sensor configured to obtain a photoacoustic signal generated from light incident on the blood vessel; and a wearable structure securable to the user and comprising the first acoustic sensor, the second acoustic sensor, the first motion sensor, the second motion sensor, and the photoacoustic sensor.

    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, an electromagnetic interference (EMI)-reducing system including a first EMI-reducing layer, a light source system and a receiver system. The light source system may include a light-emitting component, light source system circuitry and a light guide system and may be configured to emit light through the first EMI-reducing layer to a first platen area via a light pipe between the first EMI-reducing layer and the platen. The light guide system may include a light-directing element for directing light from the first EMI-reducing layer to the light pipe. The receiver system may be configured to detect acoustic waves corresponding to a photoacoustic response of a target object in contact with the first platen area to light emitted by the light source system. The first EMI-reducing layer may reduce a level of EMI emitted by the light source system circuitry that is received by receiver system circuitry.
