  • Patent number: 7753049
    Abstract: A fluid regulation system is provided comprising a source of a fluid, a tube in communication with the source for delivering the fluid from the source to a site, and a valve for controlling the rate of fluid flow from the source to the site. A remote control unit for controlling the valve is also provided to allow the user to adjust the rate of fluid flow from the source through the tube to the site. Typically, the system excludes any means for automatically adjusting the rate of fluid flow from the source through the tube to the site. The invention is particularly useful when the valve is out of the user's reach. Also provided is a method for delivering of a fluid to a site.

  • Patent number: 7552731
    Abstract: A gas regulation system is provided comprising a source of a breathable gas, a tube in communication with the source for delivering the breathable gas from the source to an individual, and a valve for controlling the rate of gas flow from the source to the individual for inhalation. A remote control unit for controlling the valve is also provided to allow the individual to adjust the rate of gas flow from the source through the tube to the individual independently from any inhalation activity by the individual. Typically, the system excludes any means for automatically adjusting the rate of gas flow from the source through the tube to the individual according to the level of physical activity of the individual. The invention is particularly useful when the valve is out of the individual's reach. Also provided is a method for delivering of a breathable gas to an individual.

  • Patent number: 5958525
    Abstract: There are described devices for creating artistic designs which are simple in approach and execution, and which enable the user to create a unique work of art without the user coming into direct contact with the medium used to create the design.The subject devices comprise a first sheet and a second sheet, the sheets being in superposed relation, sealed around their periphery and defining a first area and a second area, a plurality of rupturable containers containing a spreadable medium, arranged in the first area and adapted to discharge the spreadable medium into the second area, provided that at least one of the sheets permits the viewing of the discharged spreadable medium.A kit is also provided which includes the subject device and additional materials, such as, for example, decorative materials for application to the device and materials with which to attach the device to various surfaces.

  • Patent number: 5356762
    Abstract: An improved film format for a self-developing, peel-apart film unit having flexible positive and negative sheet elements and a pod of developer liquid, wherein at least one of the sheet elements bends when a force is applied to a trailing edge thereof to effect sheet element movement. Pockets are formed on the leading end of each sheet element so that a force may be readily coupled thereto without bending either sheet element while they are being moved, for example, into a developer liquid spread system for subsequent film processing.

  • Patent number: 5130731
    Abstract: A film holder provides a lighttight environment where a film unit may be inserted while enclosed within a lighttight envelope. After insertion the envelope may be removed from the film unit to allow the exposure of the film unit by a source of electromagnetic radiation mounted on one wall of the holder. The source of electromagnetic radiation is mounted on a block to reciprocate back and forth toward the film surface to allow the source of electromagnetic radiation to press against the film unit when the envelope is retracted from the holder and the block may be withdrawn from contact with the film unit to allow the reinsertion of the envelope to cover the exposed film unit.

  • Patent number: 5034736
    Abstract: A liquid-crystal display system includes a display having a bistable liquid-crystal material, such as a ferroelectric material, and two sets of electrodes disposed substantially perpendicularly to each other and on opposite sides of a layer of the liquid-crystal material. In each set of electrodes, drive circuitry is connected via resistors to front terminals of each of the electrodes, and via resistors to back terminals of each of the electrodes. The drive circuitry provides further that drivers having equal number of output drive ports are coupled via a network of electrical conductors to the front terminals and the back terminals of electrodes in each set of the electrodes in accordance with an arrangement wherein the front terminals are arranged in groups such that, within each group, the front terminals are connected to corresponding ports of a driver.

  • Patent number: 4895769
    Abstract: A stainable polymeric sheet material adapted to the production of a light polarizer therefrom is provided by a method, according to which, a support sheet of amorphous polymeric material is uniaxially stretched in a first direction (at or above the glass transition temperature of the polymeric support material), a layer of polyvinyl alcohol (PVA) is coated from an aqueous PVA-containing composition onto the uniaxially stretched support material, and the PVA-coated uniaxially stretched polymeric sheet material is stretched along a second direction, at an angle within about .+-.60 degrees to a normal to the first direction of stretch. The method provides a material which can be converted, by incorporation of visible dichroism into the PVA layer, to a light polarizer which combines efficient light polarizing properties and good mechanical strength and resistance to fracture along the stretch directions.
