A system uses a wearable electronic device to monitoring behavior of an operator of a vehicle. The wearable device is worn on the head of the operator of the vehicle and includes one or more motion sensors. A processor of the wearable device or of a proximate portable electronic device receives data from the one or more motion sensors and detects a pattern of motion based on the data. The system then may determine a physiological state or physical behavior of the driver based on the detected patterns or motion. Detected physiological states may include head bobs associated with sleepiness. Detected physical behaviors may include dangerous behaviors such as phone usage, prolonged gazes, sudden lane changes, or hard braking or steering.

Methods for obtaining a sample from a subject include providing a sample collection room. Samples may be small, e.g., a finger-stick. A method is provided for sample collection comprising: obtaining, in a sample collection room, a sample from said body part of said subject; monitoring activity in the sample collection room using at least two motion capture devices positioned to view a field of interest in the sample collection room; and alerting a technician performing the sample collection if a non-conforming action by the technician is detected by at least one of the motion capture devices.

Embodiments regard nutrition assessment using a handheld device. An embodiment of an apparatus includes a handle with a controller within the handle, an attachment arm extending from the handle, and a user-assistive device coupled with an end of the attachment arm, wherein the apparatus is to determine a mass held by the user-assistive device, the determination being made during a task by a user of the handheld tool including manipulation of the handheld tool.

An article of clothing includes user-protection circuitry, integrated into the article of clothing. The user-protection circuitry includes condition-detection circuitry, which, in operation, generates one or more indications related to an environment of the article of clothing. The user-protection circuitry also includes broadcast circuitry including at least one pulsing device, and control circuitry. The control circuitry, in operation, activates the broadcast circuitry based on the one or more indications related to the environment of the article of clothing generated by the condition-detection circuitry.

An apparatus is suitable for measuring a photoplethysmogram (PPG). A photoplethysmographic sensor apparatus may include a casing defining a surface, a plurality of optical emitters configured to emit radiation extending from the surface, at least one photo sensor configured to capture radiation emitted by at least a subset of the plurality of optical emitters. At least a first measurement configuration and a second configuration is defined by the plurality of optical emitters and the at least one photo sensor such that the first and the second measurement configuration provide different measurement channels by including at least partially different sets of at least one optical emitter and at least one photo sensor. The first and second measurement configurations define different spatial configurations, each of which is line symmetric with respect to an imaginary line along the surface.

A measuring apparatus as an aspect of the present invention includes: a first signal acquirer that acquires a pulse wave signal of a living body; a second signal acquirer that acquires a body motion signal of the living body; a frequency analyzer that converts the pulse wave signal and the body motion signal to a frequency domain to generate frequency domain signals, and estimates a frequency of a pulse wave of the living body on the basis of the frequency domain signals; and a time domain analyzer that calculates biological information about the living body on the basis of the frequency.

The present disclosure relates to a method and system for recommending optimal ergonomic position for a user of a computing device by a recommendation system. The recommendation system receives user data from one or more data sources and extracts a profile of the user from a repository based on the user data. The recommendation system identifies one or more critical areas of the user, where each of the critical areas are associated with a plurality of pre-defined position parameters and also monitor the plurality of pre-defined position parameters of the user to determine corresponding values. The recommendation system compare the values of the plurality of pre-defined position parameters with predefined values of the pre-defined position parameters and identify deviations in one or more of the plurality of pre-defined position parameters based on the comparison and provide recommendations for correcting the deviations from the pre-defined position parameters to the user.

The invention relates to a system for acquiring the vital status of animals, which comprises at least one first device for acquiring vital functions, and at least one signal transmission means, wherein the first device has at least two first and/or second sensors arranged at a distance from each other. The components of the system for acquiring the vital status of animals can be detachably connected with each other by connectors.

The invention further relates to a method for determining the vital status of animals, wherein the vital functions are acquired by a first device with at least two first and/or second sensors arranged at a distance from each other, wherein the acquired data are transmitted by at least one signal transmission means to a data processing device, and there processed and evaluated, and from the data processing device to an external output device, which outputs the vital status of animals.

This document describes assessing cardiovascular function using an optical sensor, such as through sensing relevant hemodynamics understood by pulse transit times, blood pressures, pulse-wave velocities, and, in more breadth, ballistocardiograms and pressure-volume loops. The techniques disclosed in this document use various optical sensors to sense hemodynamics, such as skin color and skin and other organ displacement. These optical sensors require little if any risk to the patient and are simple and easy for the patient to use.
