According to one embodiment, a detection device includes a substrate, a light detector, a light emitter. The substrate is light-transmissive. The light emitter is provided between the substrate and the light detector. The light emitter includes a first electrode, a light-emitting layer, and a plurality of second electrodes. The first electrode is provided between the light detector and the substrate. The first electrode is light-transmissive. The light-emitting layer is provided between the light detector and the first electrode. The second electrodes are provided between the light detector and the light-emitting layer.

An abnormality processing system is provided capable of executing appropriate processing in cases where an abnormality occurs in a worker's living body. A management computer 300, if determining that an abnormality is present in a worker's living body, transmits an abnormality signal to an administrator terminal 100, a work device 200, a worker camera 20 and a surveillance camera 50. When receiving the abnormality signal, the administrator terminal 100 displays an image showing that an abnormality has occurred. When receiving the abnormality signal, the work device 200 stops operation. When receiving the abnormality signal, the worker camera 20 and the surveillance camera 50 transmit to the management computer 300 imaging data containing at least data of images before and after a timing at which the abnormality has occurred in the worker's living body.

Provided according to embodiments of the present invention are methods of monitoring individuals that include securing a photoplethysmography probe to at least one of a pre-auricular region and a post-auricular region of the individual and obtaining photoplethysmography signals from the photoplethysmography probe. Photoplethysmography probes and helmets related to such methods are also described herein.

Methods and systems for simultaneous sub-Nyquist measurement of a plurality of bioelectric signals are disclosed. A system includes measurement and reference electrodes configured to measure a first and a second bioelectric signal simultaneously. The first signal is within a first frequency band, the second signal is within a second frequency band, the second band is higher than the first band, and the first and second bands are separated by a frequency gap. The system also includes a filter for attenuating in the frequency gap and a sampler configured to sample, by conducting a sampling at a sampling frequency, the first and second bioelectric signals as measured simultaneously by the measurement and reference electrodes. The sampling frequency is lower than the Nyquist frequency for the second signal. An alias of the second signal caused by the sampling is in the frequency gap. The alias does not overlap the first band.

A personal wearable headband having far infrared and temperature measurement functions includes a headband body defining a headband receiving space and having a plurality of far infrared particles blended in the headband body, a window communicating with the headband receiving space, and a through hole communicating with the headband receiving space and opposite to the window. A temperature measuring unit is disposed in the headband receiving space and includes a temperature measuring element configured to contact the forehead of a user for detecting a temperature thereof, and a display screen corresponding in position to the window and configured to display the temperature detected by the temperature measuring element.

A fall detection system includes a wearing apparatus for wearing by a user and a processor connected to the wearing apparatus. The wearing apparatus is set with an inertial sensor for detecting user motion data. The processor is connected with the inertial sensor of the wearing apparatus. When the user's fall state is recognized, further obtaining the motion data of the user at the time of the stand by the inertial sensor and comparing the motion data according to a normal posture condition and/or an abnormal posture condition in a database to determine damage severity of the user.

A head guard is provided. The head guard includes one or more sensors as part of an sensory input and communications system. The head guard wirelessly communicates data to remote computing devices for intelligent data collection.

A system, method, and wireless earpieces for determining the status of the user. Sensor measurements of the user are performed utilizing a radar sensor of the wireless earpieces. The sensor measurements are analyzed. The status of the user is determined utilizing at least the sensor measurements of the radar sensor of the wireless earpieces. An alert is communicated to the user in response to there being a change in the status of the user.
