Abstract: A method for preventing and detecting a fall of an individual and implementing a system worn by the individual. The system includes a plurality of sensors and an alarm. The plurality of sensors includes a triaxial accelerometer and a barometric sensor. Each sensor of the plurality of sensors generates a signal and is connected to a microprocessor. The microprocessor is configured to execute a computer program stored in a memory to collect and analyze data issued by the plurality of sensors, and to trigger an alarm in response to an analysis of the data.

Abstract: A system to assess a gaze direction including a device featuring a rim for holding a glass and having two IR emitters in separated locations of the rim. Each IR emitter having a light emission cone and emitting a beam directed toward the eye of the user to produce a lighting spot on the cornea. The rim further includes an IR receiver. The two IR emitters are activated one at a time in a sequence.

Abstract: A method for preventing and detecting a fall of a user and implementing a system including sensors and alarm, a pair of eyeglasses with hinged stems including rims for supporting glasses, worn by the user. The sensors are set in the hinged stems and the rims of the eyeglasses. The sensors include a triaxial accelerometer, an IR transmitter and an IR receiver of infra-red light both directed to the cornea of the user, and a barometric sensor. The triaxial accelerometer signal is acquired and processed to derive a walking pace parameter, a sit to stand parameter, a head posture parameter and an acceleration magnitude over the three axes. A composite index is computed based on the walking pace, the sit to stand and the head posture parameters. The alarm is generated if the first composite index exceeds a threshold.

Abstract: A system having eyeglasses including hinged stems, a plurality of sensors and an alarm, and a method implanting the system. The system additionally includes a triaxial accelerometer, an IR transmitter, an IR receiver, and a barometric sensor. The sensors are set up in the stems and the rims of the eyeglasses and connected to a processing and calculation unit having a microprocessor and a memory. A computer program in the processing and calculation unit collects and analyzes data issued by the sensors, and triggers the alarm based on the analysis of the data.
