Inventor: HOFFMAN STEVEN M
IPC: G09G5/00
Filed: 1994-06-13
Abstract: A display circuit and associated method, including a high-persistence display element (1018), such as a liquid crystal display device (130)) which visually displays sequences of informational image frames (260, 266) while minimizing interference between successive ones of the frames. A sequence of informational image frames are displayed upon the display element (1018), thereby to generate a visual signal which appears to scroll across the display element. Blank image frames (b) are interspersed between successive ones of the informational image frames to reduce thereby interference between successive ones of the informational image frames.

Title: Process for preparing low density porous crosslinked polymeric materials
Inventor: BROWNCOMBE THOMAS FAIRCHILD
IPC: C08J9/28
Filed: 1994-01-24
Abstract: In a process for the preparation of a low density porous crosslinked polymeric material by polymerizing a water-in-oil high internal phase emulsion, curing time of the monomers in the emulsion can be reduced without adversely affecting polymer properties by first advancing one or more of the monomers. All or a portion of the monomers are advanced in the presence of an advancement initiator or a free-radical-producing radiation source for about 5 % to about 95 % of the time effective to form a solid. Then, a water-in-oil high internal phase emulsion is formed with the advanced and optionally additional  or the advanced monomers are added to a water-in-oil high internal phase emulsion containing other monomers. The emulsions containing the advanced monomers are cured. The process provides an improved method to incorporate volatile monomers in the porous polymeric material. The curing time is further reduced by carrying out the polymerization and crosslinking in the presence of an alkylperoxycarbonate or an alkylperoxycarboxylate polymerization initiator that is branched at the 1-position and/or the .alpha.-position.
Patent CA-2170085-A1 (CA)
Title: Coin acceptance method and apparatus
Inventor: MORUN MARK J
IPC: G07F5/24
Filed: 1996-02-22
Abstract: A method and apparatus for accepting coins of denominations that have and do not have coin tubes for making change in a coin mechanism is described. One aspect of the invention concerns a method for calculating an overpay amount. The overpay amount is set to equal the value of the lowest value coin with a tube minus the value of the lowest value non-tubed coin. Thus, when the lowest value coin tube is empty a vending machine customer will be permitted to insert low value, non-tubed coins up to the overpay value to increase the likelihood of enabling a vend of an item to take place. Another aspect of the invention relates to the acceptance of high-valued, non-tubed coins. The high-value non-tubed coins are acceptable if adequate change exists in the coin tubes to payback their value plus the value of any existing credit, if their value plus any credit value is greater than the maximum vend price, and if each of the vend prices in the vending machine permit adequate change to be returned to the customer.

Title: Holographic backlight for flat panel displays
Inventor: SMITH RONALD T
IPC: F21V8/00
Filed: 1996-03-13
Abstract: An improved holographic backlight (10) and liquid crystal display (21) system. The holographic backlight (10) comprises a cold cathode fluorescent tube (11) for providing white light, and a light pipe (13) disposed to receive the white light. A phase retarding film layer (14) is attached to a first surface (15) of the light pipe (13). A double-layer reflection/transmission hologram (16) is disposed on an output surface (17) of the light pipe (13) opposite the film layer (14). Light from the cold cathode fluorescent tube (11) is injected into the light pipe (13), and is diffracted off of the double-layer hologram (16). This produces quasi-collimated s-polarized light having well-defined spectral colors that is transmitted by the hologram (16) in an array of red, green, and blue patches of light corresponding to the clear apertures of the red, green, and blue elements (22) of an active matrix liquid crystal display (21). The result is a liquid crystal display (21) with high display brightness, reduced battery power requirements, increased battery lifetime, and high contrast over a wide viewing angle.

Abstract: A cover for heat pumps enhances the productivity and energy efficiency of heat pumps.  It can be insulative in nature reducing heat loss and thus raising the temperature of the heat pump.  It can provide heat to the heat pump.  One form consists of a geodesic dome having magnifying lenses in its polygonal faces.  The lenses focus incident sunlight regardless of direction and angle of the sun onto the heat pump raising its temperature and thus energy efficiency, reducing energy expenditure and associated cost.  The cover also protects the heat pump from convective (including wind) heat loss and from radiative heat loss, due to green house properties of the cover.
