Abstract: A method determines a total velocity average cross-section parameter ?tot? in a relationship of the form ?loss(U)=nb?tot?·ƒ(U, Ud), where: ?loss(U) is a rate of exponential loss of sensor atoms from a cold atom sensor trap of trap depth potential energy U in a vacuum environment due to collisions with residual particles in the vacuum environment; nb is a number density of residual particles in the vacuum environment; Ud is a parameter given by U d = 2 ? k B ? T / m bg ? 4 ? ? ? ? ? 2 m t ? ? ? tot ? v ? which relates the masses of the sensor atoms mt and residual particles mbg to the total velocity average cross-section parameter ?tot?; and ƒ(U, Ud) is a function of the trap depth potential energy U and the parameter Ud which models a naturally occurring dependence of the loss rate ?loss(U) on the trap depth potential energy U and the parameter Ud, where ƒ(U=0, Ud) is unity for all Ud.

Abstract: An exercise machine has a main frame, two base link members supported for cyclical movement on base tracks on the main frame, two handles pivotal about a handle axis on the frame in which the handles are operatively connected to the base link members respectively such that a cyclical movement of the handles drives the cyclical movement of the respective base link members, a foot support carried on each base link member for supporting a respective foot of the user thereon through a walking motion of the user as the base link members are moved cyclically, a torso support on the main frame supporting a torso of the user thereon having one or more degrees of freedom relative to the main frame, and leg linkages connected between the main frame and respective ones of the base link members with bracing to secure legs of the user therein.

Abstract: A mobility system includes a wheeled base, an exoskeleton assembly, and a docking assembly arranged to support the exoskeleton assembly on the wheeled base. The exoskeleton assembly has an upper torso portion, upper leg portions pivotal relative to the torso portion and lower leg portions pivotal relative to respective ones of the upper leg portions. The docking assembly is operable to couple the exoskeleton assembly to the wheeled base in a sitting position. The seating surface in the sitting position and the position control motors for operating the exoskeleton from sitting to standing are all separable from the wheeled base together with the exoskeleton assembly. Alternatively, extensible links may dock the standing exoskeleton to the wheeled base so that the base can trail the exoskeleton through a walking motion.

Abstract: An apparatus and method that can measure flux density in-situ under high vacuum conditions includes a means for confining a collection of identical, elemental sensor particles to a volume of space by initial cooling by laser or another method, then confinement in a sensor volume using externally applied magnetic and/or optical fields.

Abstract: A wearable tubing safety vest configured to harness medical treatment delivery tubing and/or communication cables. The tubing safety vest comprises a vest component having a body-encompassing component cooperable with a plurality of releasably securable flaps, and an elongate tubing harness configured to releasably receive and retain therethrough at least one of medical treatment delivery tubing and communication cables. The tubing harness may be securely engaged with the vest component or alternatively, at least one hinge component can be interposed the vest component and the tubing harness. The vest component is configured for demountably encircling a mammalian body torso, e.g, a human infant torso, juvenile torso, or an adult torso. The tubing harness may be demountably engaged with the front or with the back of the vest component. The wearble tubing safety vest may be optionally configured for demountable engagement about an animal's torso.

Abstract: An air flow deflector comprising (a) a deflector body having an outer surface, the deflector body providing an air passage extending through an inlet, a throat and an outlet, the size of the inlet is greater that the size of the throat; (b) a pair of channels provided between the inlet and the outlet and each of the pair of channels having a venturi profile; and (c) an outlet portion of the air flow deflector provided between the throat and the outlet to provide a gradual transition between the throat and the outlet; wherein the air flow deflector increases an air flow velocity of air entering said inlet.

Abstract: A raising and lowering device, particularly suitable for incapacitated human or animal patients. The device includes a load carrying support having at least one elongated arm including a proximal end section and distal end section. The arm is pivotable on the device at the proximal end section and movable by pivoting between an operating position in which the support is positioned for carrying said load, and a stored position in which the arm forms a graspable handle allowing an operator to carry the device. The invention also relates to components suitable for use with the device.

Abstract: A portable multiple-component articulating support apparatus for engaging, moving, orientating and manipulating a hand-operated power tool within and throughout a three-dimensional workspace. The apparatus includes a clamping device for demountable engagement with a structural element, one or more elongate double-axis hinge member, one or more spacer elements having opposite ends adapted for detachable engagement and rotational communication with the clamping device and the double-axis hinge member, a vertically disposed pivotably connected counterbalance arm assembly adapted for detachable engagement and rotational communication with the double-axis hinge member. The counterbalance arm assembly is equipped with a gas-charged cylinder for balancing the weight of hand-operated power tools. The clamping device, a counterbalance element, one or more spacer elements and one or more double-axis hinge elements alternating therebetween, are interconnected with removable hinge pins.
