A method of commanding and controlling a mobile apparatus (wheelchair) based on the assimilation of visual parameter and brain activity data includes validating a desired position of gaze (the iris) in the environment using the physiological brain characteristics of the potentials mentioned in P300 and SSVEP. These supply a control unit and are used to assess the user's state of mental fatigue using an algorithm based on the theory of evidence. A unit detecting the user's emotional state is also implemented using the alpha and beta waves from the parietal, central and frontal region of the cerebral cortex and the user's heart rhythm. The assimilation between these two units makes it possible to define a mode of operation in real time: manual, semi-autonomous or autonomous, which corresponds to the user's emotional or fatigue states as well as the characterization of the environment (safe path, detection of obstacles, locked situation).

The invention provides optical technique for measuring metabolism in a living body that can further reduce an error in measurement even if distance between irradiation and detection is fixed. The living body is classified into measurement regions and different measuring wavelengths are set according to the classification. For example, the head is classified into four regions of a parietal region, a frontal region, a temporal region and an occipital region and a wavelength according to each tissue is set in a wavelength selecting system. In measurement, wavelengths according to each measurement region are selected by multiple wavelengths-light radiating means. Besides, for a region having large personal difference, premeasurement is made using plural combinations of wavelengths and wavelengths are selected using a calculated error in measurement as a criterion.

The invention relates to a system and/or an apparatus for an improved helmet system that may help reduce the severity of injuries by enhancing overall helmet protection through uniquely designed facemasks and facemask bumpers. The facemask and facemask bumpers that are particularly adapted to redistribute pressure and impact forces, decrease vibration, sudden shock, noise and/or the peak forces transmitted from the facemask to the rest of the helmet system. The facemask bumpers may be disposed into specific regions of the facemask, including the brow region, the glabella region, orbit region, the frontal region, the mandible (front, right and/or left side) region, the maxilla region, the nasal region, zygomatic region, the ethmoid region, the lacrimal region, the sphenoid region and/or any combination thereof.

Typically, high NREM stage N3 sleep detection accuracy is achieved using a frontal electrode referenced to an electrode at a distant location on the head (e.g., the mastoid, or the earlobe). For comfort and design considerations it is more convenient to have active and reference electrodes closely positioned on the frontal region of the head. This configuration, however, significantly attenuates the signal, which degrades sleep stage detection (e.g., N3) performance. The present disclosure describes a deep neural network (DNN) based solution developed to detect sleep using frontal electrodes only. N3 detection is enhanced through post-processing of the soft DNN outputs. Detection of slow-waves and sleep micro-arousals is accomplished using frequency domain thresholds. Volume modulation uses a high-frequency/low-frequency spectral ratio extracted from the frontal signal.

A touchscreen is constructed directly on the glass surface of a cathode ray tube (CRT) (15). To solve the problem of insufficient space between the CRT's bezel and frontal region (16) to accomodate the transducers (20) for the touchscreen, the transducers (20) are moved away from the frontal region (16), to the highly curved shoulder region (17) of the CRT (15). To preserve acoustic signal strength, the positioning of the transducers (20) is chosen to take advantage of the fact that an acoustic wave on a non-Euclidian surface travels along a geodesic path (31). Allowance is also made for the acoustic lens and prism effect of the corner regions (26) of the CRT (15), where the transducer (20) may be located.
