A machine-implemented method for automated detection of drowsiness, which includes receiving from an imaging device directed at the face of an operator a series of images of the face of the operator onto processing hardware, on the processor detecting facial landmarks of the operator from the series of images to determine the level of talking by the operator, the level of yawning of the operator, the PERCLOS of the operator, on the processor detecting the facial pose of the operator from the series of images to determine the level of gaze fixation by the operator, on the processor calculating the level of drowsiness of the operator by ensembling the level of talking by the operator, the level of yawning of the operator, the PERCLOS of the operator and the level of gaze fixation by the operator, and generating an alarm when the calculated level of drowsiness of the operator exceeds a predefined value.

An intelligent psychological assessment and intervention system based on an independent space, comprising a psychological intervention cabin and a central database which achieves data interaction with the psychological intervention cabin. The psychological intervention cabin comprises a housing, a data acquisition module, a data processing module, and an intervention module; the data acquisition module acquires physiological and psychological data of a subject; the data processing module performs operations on the acquired data, establishes a multi-dimensional state point of the subject according to a mathematical model of the data processing module, matches it with data in the central database, finds a suitable intervention procedure for the subject, and guides the intervention module to carry out intervention; in the intervention process, the data acquisition module continuously acquires the physiological and psychological data of the subject, and the data processing module forms a new multi-dimensional state point according to new data and re-matches it to adjust the intervention procedure. By repeating this cycle, the intervention procedure is continuously adjusted in the intervention process to seek a most suitable intervention solution for the subject, and an optimal intervention effect is achieved.

Hearing management, using a portable device or integrated portable devices, can include generating during a hearing diagnostics phase an audiogram based on responses of a user to signals conveyed to the user. In response to detecting ambient noises during the hearing diagnostics phase, noise cancellation can be performed to cancel the ambient noises in conjunction with conveying the signals to the user. During a hearing enhancement phase, sounds can be captured with the portable device. The captured sounds can be enhanced in real-time during the hearing enhancement phase by amplifying select frequencies of the captured sounds using signal gain. The frequencies can be selected, and the signal gain determined based on the audiogram. The captured sounds, now enhanced, can be conveyed to the user as frequency-enhanced sounds.

A volumetric sampling apparatus for volatile compounds comprises a structure, such as a channel structure that forms a continuous curve between the inlet port and the outlet port. A gas flow induced in the structure urges volatile compounds collected via transdermal diffusion toward the outlet port, where the volatile compounds may be collected and analyzed by a gas composition analyzer coupled to the outlet port.

Disclosed is a breath sampling device comprising a buffer tube, sensor module and breath sampling port. The buffer tube has a proximal end into which a user exhales and a distal end opposite the proximal end, the sensor module is at the distal end and used for measuring parameters of a breath exhaled by the user into the buffer tube, and the breath sampling port is disposed between the proximal end and distal end. The used exhales into the distal end and a portion of the exhaled breath can be diverted into the sampling port substantially without contacting the sensor module.
