Abstract: Wearable devices are described herein including at least two photodetectors and a mount configured to mount the at least two photodetectors to an external surface of a wearer. The at least two photodetectors are configured to detect alignment between the wearable device and a target on or in the body of the wearer (e.g., to detect the location of vasculature within the body of the wearer relative to the at least two photodetectors). Alignment of the at least two photodetectors relative to the target could enable detection of one or more physiological properties of the wearer. For example, the wearable device could include a sensor configured to detect a property of the target when the sensor is above the target, and alignment of the target relative to the at least two photodetectors could include the sensor being located above the target.

Wireless mobile communication device assets include software applications, persistent data, communication pipes, and configuration data, properties or user or subscriber profiles.

Abstract: Devices and systems are provided to electrically and optically detect hemodynamic properties of a body. Such devices are configured to detect electrocardiographic signals and photoplethysmographic signals and to operate a single analog-to-digital converter (ADC) to sample one or more of each of such signals. This includes operating a multiplexer to connect electrical signals related to the detected optical and electrical properties to the single ADC during respective different sampling times or periods. This can include connecting the detected electrocardiographic signals and photoplethysmographic signals to the ADC during alternating periods of time. Using a single ADC to sample one or more of each of electrocardiographic signals and photoplethysmographic signals can provide samples of such signals that have a relative timing that is known, stable, and controllable.

Abstract: Systems are provided for detecting the flow of blood in vasculature by illuminating the blood with a source of coherent illumination and detecting one or more time-varying properties of a light speckle pattern that results from the scattering of the coherent illumination by tissue and blood. The movement of blood cells and other light-scattering elements in the blood causes transient, short-duration changes in the speckle pattern. High-frequency sampling or other high-bandwidth processing of a detected intensity at one or more points in the speckle pattern could be used to determine the flow of blood in the vasculature. Such flow-measuring systems are also presented as wearable devices that can be operated to detect the flow in vasculature of a wearer. Systems and methods provided herein can additionally be applied to measure flow in other scattering fluid media, for example in a scattering industrial, medical, pharmaceutical, or environmental fluid.

Abstract: Systems and methods are described that may provide audio information about an environment around a wearable device. Such audio information may be correlated with other biometric data to provide physiological information, e.g. regarding a wearer of the wearable device. For example, an illustrative method includes receiving an audio signal via a microphone of a wearable device and rectifying the audio signal with a peak detector. The method further includes amplifying the rectified signal with a logarithmic amplifier and causing an analog to digital converter (ADC) to sample the logarithmic signal. The method also includes causing the ADC to convert the sampled logarithmic signal to a digital output and storing the digital output in a memory of the wearable device. In some embodiments, the method includes transmitting the digital output to a computing device, which may correlate the digital output with other biometric data.

Abstract: Wearable devices are provided including electrical contacts to detect voltages or other biosignals when mounted to the skin of a wearer. The impedance between a pair of the electrical contacts can be detected and the device operated based on the detected impedance. The device can detect an electrocardiogram or other biopotentials using the electrical contacts if the detected impedance falls below a specified threshold. The device could indicate that the detected impedance is below the specified threshold, e.g., such that a wearer could contact one of the electrical contacts with a finger to allow detection of an electrocardiogram between the arms of the wearer. The device could indicate that the detected impedance remains greater than the specified threshold, e.g., such that a wearer could re-mount the wearable device to improve the electrical connection between the electrical contacts and the wearer's skin.

Abstract: A light source emits light into a first portion of a living body. Functionalized particles within the body are configured to specifically bind to a target analyte, and upon receiving the emitted light, undergo a reaction that separates a detectable label from the functionalized particle. A sensor device is configured to detect a response signal from a second portion of the living body that is indicative of an abundance of the detectable label in the second portion. A control system uses the sensor device to obtain sensor data indicative of the response signal from the second portion of the living body detected by the sensor device during a measurement interval, and determines a presence or absence of the target analyte within the first portion of the living body based in part on the obtained data.
