Abstract: A system for detecting facial movements of a user includes: a sensor assembly including: an elastic member 110 configured to couple to a headset and contact a face of a user, proximal and offset from ocular regions of the face of the user and a substrate that defines a set of discrete electrical channels and a set of electrode tabs distributed along the elastic member, wherein each electrode tab is configured to proximally contact a muscular region on the face of the user; and a controller configured to sample a set of sense signals from the set of electrode tabs via the set of discrete electrical channels and to interpret changes in the set of sense signals over time as expressions on the face of the user when the headset is worn by the user.

Abstract: A method for detecting facial emotions includes: recording a set of electromyograph signals through a set of sense electrodes arranged about a viewing window in a virtual reality headset; deducting a reference signal from each electromyograph signal in the set of electromyograph signals to generate a set of composite signals; for each composite signal in the set of composite signals, transforming the composite signal into a spectrum of electromyograph components; for each facial action unit in a set of facial action units, calculating a score indicating presence of the facial action unit in the user's facial musculature during the sampling interval based on the spectrum of electromyograph components; and mapping scores for the set of facial action units to a facial expression of the user during the sampling; transforming the facial expression of the user to an emotion of the user based on an emotion model.

Abstract: The invention provides a system for preventing fluid exchange between the interior and exterior of containment enclosures such as process-, hazard-, and research-enclosure systems generally, gloveboxes, containment systems, isolation systems, confinement systems, cleanrooms, negative air systems, and positive air system areas while simultaneously providing material transfer into and out of the enclosures. The invention also provides a method for transporting material into or out of a containment structure.

Abstract: The invention provides a system for preventing fluid exchange between the interior and exterior of containment enclosures such as process-, hazard-, and research-enclosure systems generally, gloveboxes, containment systems, isolation systems, confinement systems, cleanrooms, negative air systems, and positive air system areas while simultaneously providing material transfer into and out of the enclosures. The system comprises a cylinder adapted to be received by a region of a containment enclosure forming an aperture so that a hermetic seal exists between the cylinder and the aperture; a canister coaxially positioned within, and in slidable communication with the cylinder such that a hermetic seal exists between the canister and the glove port. The invention also provides a method for transporting material into or out of a containment structure.

Abstract: A process for automatically controlling water level in a washing machine having a motor drive coupled to energize a motor that drives the agitator is provided. The process allows for selecting a target water level based on one or more water-level selection signals. The method further allows for measuring a parameter indicative of the water level based on an actual inertial response of the agitator. A comparing step allows for comparing the actual agitator inertial response against a target agitator inertial response, and a selecting step allows for selectively actuating one or more water valves for allowing passage of water so as to adjust the water level of the washing machine based on deviations between the actual agitator inertial response and the target agitator inertial response.

Abstract: A process and system for controlling respective agitator motion patterns in a washing machine having a motor drive coupled to energize a motor that drives the agitator is provided. The process allows for selecting a desired agitator motion pattern based on one or more pattern selection signals. The process further allows measuring one or more parameters indicative of the actual agitator motion pattern. A comparing step allows for comparing the actual agitator motion pattern against the desired agitator motion pattern, and an adjusting step allows for adjusting one or more control signals supplied to the motor drive for correcting deviations between the actual agitator motion pattern and the desired motion pattern.
