Abstract: A computer based presentation system allows a presenter to view on a monitor associated with a computer an image prior to its display on a television monitor or projection system to an audience. The system includes a video frame buffer having an input coupled to a video port of the computer for receiving a video signal generated by the computer. The buffer captures and stores in memory a frame carried by the video signal. An output of the video buffer is connected to a video display adapter for continuously converting the stored image frame to a second video signal for transmission to a television monitor for display to an audience. A command to update the video frame buffer is generated by a hand-held remote and transmitted to a serial port of the computer through a photoelectric sensor housed with the video buffer and video display adapter. The computer signals the video buffer through the serial port to update the contents of its memory with the next image frame carried by the video signal.

Abstract: The invention comprises a non-restrictive, constant pressure refrigerant recycling and cooling unit that interrupts the normal refrigerant cycle to permit a lower temperature liquid to enter the expansion device, and thus provide a lower temperature, and therefore a lower pressure gas for delivery to the inlet side of the compressor, which acts to reduce the energy requirement and cost to operate the compressor. This reduction in pressure and temperature also results in lower operating costs and lower maintenance costs and utilizes less refrigerant quantity requirements.

Abstract: The present invention includes a remote mouse controller having a disc controller actuable by a user for the infrared remote signalling of all common mouse functional operations.

Abstract: A protector block assembly for coupling a plurality of surge protectors to multi-line telecommunications cables includes a multi-layer printed circuit, to which has been mounted at least two cable connectors, and a protector block having a plurality of sockets for receiving standard surge protectors. A plurality of pins electrically and physically connects the multi-layer printed circuit board to the sockets on the protector block in a manner that a unique signal path exists between each lead in each connector and one of the sockets on the printed circuit board. The multi-layer printed circuit board includes traces on multiple layers that have a width and a copper content sufficient to carry current surges without breaking down.

Abstract: Provisional road sign barriers and permanent medians are formed based on the correlative, interconnectable arrangement of a number of equal modules, some male and others female, for connecting, which are made of adequate plastic, are hollow and equipped to enclose an electrical supply and corresponding internal lamps that will provide a correct view and real volume of the formed barrier. The modules include, in addition to a metallic reinforcement structure, some sheets that act as elements which absorb the impact of vehicles. The modules will be filled with bags of water, or with sand and/or concrete, as weights, to form a static barrier that carries out the function of signposting and beaconing for works on highways and similar places, and of protecting against the impact of vehicles.

Abstract: The invention includes a back support belt having a dual-belt assembly in which a wide, elastic inner belt completely encircles the abdominal and lower lumbar regions of the body. The inner belt is secured before a second, relatively less elastic outer belt, primarily providing rigid support, is fastened over the inner belt. The middle and side panels of the inner belt provide additional support to critical areas of the region through the use of supplemental internal padding.

Abstract: A method for retrofitting a metal roof formed of overlapping R panels having major ribs and panel flats spaced therebetween includes the steps of removing fasteners disposed along the overlapping margins of adjacent R panels; plugging the holes formed when the fasteners are removed from the R panels; positioning a RETRO R panel having dual-tiered major ribs and panel flats spaced therebetween over the metal roof; aligning the major ribs of the RETRO R panel with major ribs of the underlying R panel; and fastening the major ribs of the RETRO R panel to the major ribs of the underlying R panel. An apparatus for retrofitting a metal roof includes a plurality of dual-tiered major ribs and a plurality of panel flats spaced therebetween, such that when installed over an existing metal roof, the major ribs of the new roof panel are aligned with the major ribs of the underlying roof panel.

Abstract: The invention is a footwear protector comprised of a single piece of material of uniform thickness and width which, when in place, forms an open-toed design protector. The protector utilizes an opening at one end to allow the insertion of any front tassel or decoration of the protected footwear and to secure the protector to the front portion of the footwear. Velcro.RTM. fasteners are located at each end of the protector's length to further secure the protector. This fastening system allows the protector to be fitted to different size footwear, and facilitates quick and easy attachment and removal of the device. Additionally, the protector is constructed of a soft, nonabrasive fabric, allowing the protector also to be used as a footwear buffing and cleaning cloth when not secured to footwear.

Abstract: An apparatus for controlling oxygen flow to a Claus type sulfur recovery unit includes system for measuring the flow(s) of feed gas and combustion air to the unit and an oxygen injection system for supplying supplemental oxygen when the oxygen demand exceeds the oxygen available in the form of combustion air. The control system also measures a unit pressure in the sulfur recovery unit and controls the flow of combustion air to the unit to maintain the unit pressure at or below a preselected level.

Abstract: An electronic presentation system is presented utilizing a wireless remote for controlling a digital computer, one or more display or storage/playback devices and an audience response system. A Terminate and Stay Resident (TSR) program within the digital computer manages the wireless remote. The digital computer running the TSR program enables the wireless remote to operate any applications program, as well as to use the computer to add spontaneously certain special effects to the presentation and to control an audience response system. In addition, the computer downloads into the wireless remote control, via a wireless communications link, data commands and signalling parameters such as modulation scheme and communications protocol with which to enable the wireless remote to generate the correct signalling to operate predefined display or storage/playback device.
