Abstract: A movable enclosure is configured to selectively enclose an area. The enclosure includes at least one side wall and an end wall attached thereto. The side wall comprises a number of individual panels that are independently movable along a track secured to the ground. The panels are selectively collapsible such that they may travel along the track and overlap one another when in a collapsed or stowed position. The enclosure may be configured in any number of intermediate positions wherein the panels are partially collapsed. Roof panels may be attached to the side walls for movement therewith, or alternatively, the roof panels may operate independent of the side walls to extend and retract between an open and collapsed configuration.

Abstract: A passive, remote sensor including an optical subsystem for receiving electromagnetic radiation scattered off a surface. A detector is responsive to electromagnetic radiation received by the optical subsystem and generates a composite signal comprising a DC current component and an AC current component. A filter extracts the DC current component from the composite signal. A light emitting device is driven by the DC current component. A detector is responsive to the light emitting device and is connected to the first detector to subtract at least a portion of the DC component from the composite signal producing a modified signal. An amplifier is responsive to the modified signal detects vibrations of the surface to be detected.

Abstract: An air delivery system includes a controllable flow generator operable to generate a supply of pressurized breathable gas to be provided to a patient for treatment. A touchless control system is associated with at least one control feature adapted to control at least one operating parameter of the flow generator. The touchless control system includes one or more sensors to detect patient hand movement and a controller to selectively activate the at least one control feature based on the patient hand movement detected by the one or more sensors.

Abstract: A fire escape ladder assembly adapted for mounting between wall support members in a building cavity of a building structure. The assembly includes a fire escape ladder enclosure mounted in the building cavity and a mounting structure passing through the enclosure and surrounding building support members to anchor the fire escape ladder directly to the building structure. The enclosure can include a portion for mounting within a wall cavity and can further include a portion for mounting within a building floor cavity. The mounting structure can include a threaded rod passing through apertures in adjacent wall studs and maintained in a centered position by lock nuts.

Abstract: Bumper Guard that can be affixed with just an adhesive and can be used for/in advertising as an advertising specialty piece that will be mounted to a bumper to protect the bumper.

Abstract: A modular engine enclosure comprised of a hood and baffle is provided to channel cooling air along passages formed between their adjacent surfaces to the radiator of a water cooled engine. The passages provide acoustic air barriers and along with selected enclosure surfaces covered with sound absorbing foam, serve to contain engine sounds within the enclosure. The passages receive air from a generally upright inlet opening and direct it evenly over the top surface of the horizontally oriented radiator. After being drawn through the radiator, the air is exhausted generally horizontally out the back of the engine compartment. The modular construction of the enclosure allows it to be easily raised and/or removed so that maintenance and service activities can be performed on the engine and its components.

Abstract: A high resolution, independent position sensor is provided, having application in a magnetic tape drive and other environments in which a linear or angular position is to be monitored. Analog outputs from an inexpensive, low resolution optical encoder are processed to correct gain and offset distortions and are used as the basis for an interpolation process. If a code strip having a 127-micron grating is used, a resolution of about 0.125 microns can be achieved.
