Abstract: A joint assembly has a housing having an inner wall surrounding an interior cavity of the housing. A slider is held captive in the interior cavity of the housing so as to define an annular volume extending radially between the slider and the inner wall of housing, the slider constrained to planar movement and a rotational degree of freedom in the housing. An annular resilient member is in the annular volume, the annular resilient member exerting a biasing force between the slider and the housing toward a neutral configuration. The housing is adapted to be connected to one of a ground/base/motion platform and a linear actuator, and the slider is adapted to be connected to the other of the ground/base/motion platform and the linear actuator.

One or more levels of balls in the inner cavity between a housing surface and a surface of the translating member to support the translation of the translating member in the housing. A motion simulator featuring one or more of the joint assemblies is also provided.

Abstract: The present relates to a washable interconnection patch, a connection assembly, and an intelligent washable garment equipped therewith. The patch receives and interconnects wires to a cable. The patch comprises two matching pieces interlocking together so as to define there between two opposite apertures. One of the apertures is adapted to receive and hold the wires, and the other aperture is adapted to receive and hold the cable. One of the two matching pieces defines on an interior face a channel to interconnect the wires to the cables. The connection assembly comprises a male connector and a female connector. The male connector defines a series of independent connection points along a length thereof. The female connector is adapted to receive the male connector, and defines along a length of an inner surface thereof a series of contact points. When the male connector is inserted within the female connector, the connection points and the contact points are aligned and in contact together.

Abstract: A portable chamber for hyperbaric/hypoxic treatment comprises a tubular body sized so as to accommodate an occupant. The tubular body is made of a non-rigid material. End frames are secured to opposed ends of the tubular body to close off the tubular body. One end frame has a door displaceable from a remainder of the end frame to provide/close access to an interior of the tubular body. Longitudinal beam members are connected at opposed ends to the end frames so as to maintain the tubular body in a taut condition between the end frames, whereby the portable chamber is in fluid communication with a pressure generator so as to receive an air supply from the pressure generator to increase a pressure in the interior of the tubular body for hyperbaric treatment.

Abstract: The present document describes an actuated chair for providing seating and inducing motion to a single user with respect to the ground as a function of motion signals synchronized with a video output of a feature length movie. The chair comprises a seat base for providing seating to the single user. The seat base has a rear edge. The chair further comprises an actuating base for receiving the motion signals. The actuating base is located substantially between the seat base and the ground and comprises a frame for interfacing with the ground. The actuating base also comprises three link members, namely a first link member, a second link member and a third link member. Each link member has one translational degree of freedom and two rotational degrees of freedom. The first link member and the second link member are attached to the seat base closer to the rear edge than the third link member. The actuating base further comprises three linear actuators for inducing motion to the seat base.

Abstract: A vehicle frame includes a plurality of hollow tubular members welded together. An opening in a side wall of the frame which receives a door or window of the vehicle is bordered by at least two hollow tubular members which are interconnected by a non-tubular, reinforcing corner member. The reinforcing corner member includes a pair of solid parallel plates spaced apart by a perpendicular cross-member. Each plate of the reinforcing corner member has integral first and second elongated portions extending on either side of a continuous curve therebetween which has a substantially constant radius of curvature such as to define a smooth transition between the integral first and second elongated portions of the plate. The reinforcing corner member distributes stress away from the curved corner and to the tubular members, thereby preventing stress concentration at a joint between the two tubular members surrounding the opening in the frame.
