Embodiments of the present disclosure relate to systems and methods of locating a patent within a facility. In one example, the system includes a beacon and a sensor. The beacon is positioned in a location of the facility. The beacon includes an infrared emitter and a processor. The processor is in communication with the infrared emitter. The processor is configured to instruct the infrared emitter to periodically emit an infrared emission. The processor modulates the infrared emission with a unique identification of the beacon that corresponds to the location of the beacon. The sensor is worn by the sensor wearer. The sensor includes an infrared receiver and a processor. The processor is in communication with the infrared received. The infrared receiver is configured to demodulate the received infrared emission to identify the unique identification of the beacon.

The disclosure is related to a method and an apparatus for human fall detection with power-saving feature. In the method, a processor is set in a sleep state under a normal operating condition, and sensor data generated by a sensor unit of the apparatus worn on a person is stored in a buffer. A processor of the apparatus is woken up from a sleep state when the processor receives a collision signal, and the processor then retrieves the buffered sensor data and current sensor data. The sensor data is processed by a fall detection program. The apparatus will generate an alarm for a fall event if the sensor data meets the preset fall conditions; otherwise, the processor returns to the sleep state. The apparatus saves power by avoiding huge data calculation while staying in the sleep state until being woken up by the collision signal.

Disclosed herein are embodiments of an athletic coaching system that includes at least one inward-facing head-mounted thermal camera (CAM) and a computer. Each CAM from among the at least one CAM is configured to take thermal measurements of a region below the nostrils (denoted TH.sub.RBN) of a user. TH.sub.RBN are indicative of an exhale stream of the user (e.g., an exhale stream from a nostril and/or from the mouth). The computer is configured to: receive measurements of movements (M.sub.move) involving the user; generate, based on TH.sub.RBN and M.sub.move, a coaching indication; and present, via a user interface, the coaching indication to the user. In one example, the coaching indication is indicative of a change the user should make to one or more of the following: cadence of movements, stride length, breathing rate, breathing type (mouth or nasal), and duration of exhales.

A method of estimating a ventilation rate in a room, the method comprising receiving a signal indicative of a concentration of at least one Volatile organic compound (VOC(t)) inside the room; processing the signal to detect at least one increase from an initial level (VOC(t0)) of the concentration of the at least one volatile organic compound; detect a corresponding maximum level of the concentration from the initial level; detecting when the concentration of the volatile organic compound returns towards the initial level or a steady state level (VOCss) from the corresponding maximum level; and determining the ventilation rate (k) based on the rate at which the concentration of the at least one Volatile organic compound returns towards the initial level or the steady state level from the corresponding maximum level.

The present invention relates to a patient with Alzheimer's disease positioning and retrieval assembly carrying an original location, including a sealing box, the upper part of the sealing box is the control part, and the lower part thereof is the display part. The locking outer plate, is fixedly connected to an alarm device communicating with the control part; the display part includes a display positioning sleeve provided within the sealing box. The display positioning sleeve comprises a display glass sleeve, a display sealing block and a display pressing column from front to back. the display glass sleeve is internally sleeved sealingly with a horizontal display glass block, a cardboard is disposed between the display sealing block and the display glass block, the front panel of the sealing box is provided with a display port fitting the display glass block. In the present invention, the control part of the power distribution control box is connected with the alarm device, and the display part of the power distribution control box displays the initial position, thereby it is convenient for people to find the patients and send them back. In addition, sealing of the display part is done by mechanical sealing structure and glass pate, and the original position is displayed by a written paper, thereby energy consumption is low.

A monitoring device for detecting wetness in a garment is disclosed. The monitoring device of the present disclosure includes a locking mechanism that slides back and forth relative to a clip that is removably attachable to a garment between a first position in which the locking mechanism locks the clip in a closed position and a second position in which the clip is in an open position. As the locking mechanism transitions from the first position to the second position, the locking mechanism opens the clip. Advantageously, the monitoring device of the present disclosure allows a caregiver to align and secure the monitoring device to a garment using only one hand.

A smart monitoring system comprising a plurality of sensor devices within a home or facility, at least one of the plurality of sensor devices comprising sensor elements configured to detect activity of an individual in the home or facility, and a computing device configured to receive activity signals from the plurality of sensor devices associated with the individual from the home or facility, parse the activity signals into scoring components by correlating the plurality of sensor devices to the scoring components, the scoring components including a sleep score, a motion score, and an event score, compute a current scoring of the individual based on the scoring components, compare the current scoring of the individual to historic scoring and peer scoring, generate a quality of life score for the individual based on the based on the comparison, and process a clinical analysis of the individual based on the quality of life score, the clinical analysis including graphical representations of the quality of life score and the scoring components.

In one example, a sensor system of a patient monitoring system includes a voiding sensor that includes an electrical circuit configured to be transitioned from a first impedance state to a second impedance state in response to a voiding event in an absorbent region of an absorbent article worn by a patient. The sensor system also includes one or more processors configured to: determine, based on whether the impedance state of the electrical circuit is open or closed, that the voiding event has occurred; and generate, based at least in part on the occurrence of the voiding event, patient status data of the patient. The sensor system also includes a communication module configured to wirelessly transmit, via a relay module, the patient status data to a remote monitoring device that is distinct from the relay module.

Systems and methods include a cellular, WiFi, and Bluetooth transceiver coupled to a processor; an accelerometer or a motion sensor coupled to the processor; and a sensor coupled to the processor to sense mood or body vital sign.

The present invention relates to a sensor arrangement comprising a support substrate and at least two microwave antennas fixedly arranged in or on said support substrate, each microwave antenna being separated from all other microwave antennas by a band-stop structure configured to cancel direct coupling between the microwave antennas, said sensor arrangement further comprising microwave signal transmission paths configured to transmit microwave signals to or from said microwave antennas. The invention also relates to a system comprising such a sensor arrangement and a method for non-invasive assessment of a property of subdermal tissue in a subject.
