Various embodiments provide systems and methods for identifying impairment using measurement devices.

A device for determining the amount or concentration of an analyte in a fluid sample and a flow rate of the fluid sample in a channel is provided. The device includes a chamber including a channel and an opening the channel in fluid communication with the opening. The device further includes a wicking component positioned adjacent to the opening configured to receive an amount of fluid from the channel. The device may further include an analyte sensor positioned on the wicking component, the analyte sensor configured to detect an analyte in fluid in contact with the analyte sensor, wherein the wicking component is configured to contact the amount of fluid with the analyte sensor. Alternatively the device may include at least one pair of electrodes configured to determine a flow rate of the fluid in the channel.

Adjustment of training protocols in virtual reality (VR) or augmented reality (AR) environments based on biofeedback are provided. In various embodiments, motion data is collected for a user while the user performs a training protocol in a virtual environment. A biometric measurement is collected for the user while the user performs the training protocol. The motion data and the biometric measurement are provided to a learning system at a remote server. The learning system determines an adjustment to the training protocol based on the motion data and the biometric measurement. The adjustment is provided by the learning system and is applied to the training protocol. In various embodiments, the adjustment, the motion data, and/or the biometric measurement may be logged in an electronic health record.

A system and method are described for controlling a vehicle interior environmental condition. A biometric sensor senses a biometric condition of a vehicle seat occupant and generates a sensed biometric condition value. A controller receives the sensed biometric condition value, a sensed interior environmental condition value, and a sensed exterior environmental condition value. Each of multiple exterior environmental condition values has an associated biometric condition value defined as optimal for the vehicle occupant. The controller determines the optimal biometric condition value associated with the sensed exterior environmental condition value, compares the optimal biometric condition value to the sensed biometric condition value, and in response to a difference between the optimal biometric condition value and the sensed biometric condition value, generates a control signal to control an actuator to control the controllable interior environmental condition to reduce the difference between sensed biometric condition value and the optimal biometric condition value.

The present disclosure provides methods and apparatus for evaluating tissue structure in damaged or healing tissue. The present disclosure also provides methods of identifying a patient at the onset of risk of pressure ulcer or at risk of the onset of pressure ulcer, and treating the patient with anatomy-specific clinical interventions selected, based on TEWL measurements. The present disclosure also provides methods of stratifying groups of patients based on risk of wound development and methods of reducing incidence of tissue damage in a care facility. The present disclosure also provides methods to analyze trends of TEWL values to detect tissue damage before it is visible, and methods to compare bisymmetric TEWL values to identify damaged tissue.

A perspiration mapping patch according to the present disclosure is attached to skin of a user to absorb sweat, and includes: a sweat absorbing layer in which a plurality of opening units is arranged: a first support layer which is stacked on a first surface of the sweat absorbing layer and includes an opening opened to correspond to each of the plurality of opening units: and a second support layer stacked on a second surface facing an opposite side of the first surface of the sweat absorbing layer.

A method of controlling a non-light emitting, variable transmission device is disclosed. The method can include receiving state information from at least one wearable device, prioritizing the received state information, sending signals from a remote management system to a first controller in response to the received prioritized state information, and changing a first transmission state of a non-light-emitting, variable transmission device to a second transmission state for the non-light-emitting, variable transmission device in response to the signals received from the first controller.

A contact sensor and system for incorporation within clothing and other wearable items to monitor activity at a body surface. The sensor includes a contact membrane having a body surface contacting area and one or more base layers of knitted fabric. The base layer(s) is thicker over an area congruent with the body surface contacting area of the contact membrane. As a result, the contact membrane is urged into the forming of a raised outer surface for projection against a body surface.

Introduced are methods and systems for: gathering human biological signals, such as heart rate, respiration rate, or temperature; analyzing the gathered human biological signals; and controlling a vibrating pillow strip based on the analysis.
