Abstract: A pet bowl water cooling system includes a bowl, a pump for removing water from the bowl, a heat transfer device, and a conduit adapted to carry the water to the heat transfer device, to carry cooled water back to the bowl. The heat transfer device can include a metal coil submersed in a relatively cool liquid medium. Preferably, the bowl includes a float valve to allow water to flow into the bowl when the float valve is activated. In an embodiment, the liquid medium includes water in a water reservoir of an evaporative cooler. In an embodiment, the evaporative cooler includes a housing that is disposed between studs of a wall. The dog bowl can be mounted on an interior wall or an exterior wall. In an embodiment, the evaporative cooler is disposed within a wall of a dog house and the dog dish is mounted thereon.

Abstract: An evaporative cooling system includes a housing that fits between a pair of wall studs of a structure. The housing includes a water pump, an evaporative pad, a water distributor, a motor, and a fan. In an embodiment, the wall studs are spaced about sixteen inches on center. This leaves about 14.5 inches between the studs, and the housing will preferably be about 14 inches in width to ensure proper fit. The unit may be about 3 to 6 inches in thickness and about 24 inches in height, protruding no more than about three inches from the inside wall. The housing also preferably includes a front cover. A ventilation grill can be installed on the exterior wall to facilitate outside air being brought into the system. In other embodiments, the studs are spaced differently (e.g., about twenty-four inches on center) or the unit is installed in a structure built using non-wood framing (e.g., SIP, ICF).

Abstract: A display includes a display device having a first polarizer and a second polarizer or a reflector, and a display layer disposed between the first polarizer and the second polarizer or the reflector. A liquid crystal layer is disposed between the display layer and one of the first polarizer and the second polarizer or reflector. The liquid crystal molecules of at least one region of the liquid crystal layer are switchable between a first state in which the display has a first display mode with a first viewing angle range and a second state in which the display has a second display mode having a second viewing angle range smaller than the first viewing angle range.

Abstract: A display is switchable between a first display mode with a first viewing angle range, a second display mode having a second viewing angle range smaller than the first viewing angle range and a multiple view directional display mode. The display includes an image display layer and a control element that is switchable between a first state in which it cooperates with the image display layer to provide the first display mode, a second state in which it cooperates with the image display layer to provide the second display mode, and a third state in which it cooperates with the image display layer to provide the multiple view directional display mode.

Abstract: A liquid crystal cell (5) comprises a layer (4) of cholesteric liquid crystal material; and a retarder (3) disposed in an optical path through the layer (4) of cholesteric liquid crystal material. The cholesteric liquid crystal material is switchable between a first state in which it cooperates with the retarder (3) to provide a first viewing angle range and a second state in which it cooperates with the retarder (3) to provide a second viewing angle range which is smaller than the first viewing angle range. The pitch of the cholesteric liquid crystal material is greater than an intended wavelength of operation of the liquid crystal cell divided by the average refractive index of the liquid crystal material. The liquid crystal cell may be used as a Viewing Angle Restriction (VAR) element, to enable another component, such as a display panel (6), to be operated in either a wide viewing mode or a narrow viewing mode.

Abstract: The invention provides for the manufacture of cheese products enhanced with a natural, biogenerated flavoring system. The natural flavoring system described herein may be used with various types of cheese and dairy products. In one embodiment, the system may be used in the production of flavor enhanced fresh cheese or cream cheese. In another embodiment, the system may be used in the production of low-fat cheese products, such as low-fat cream cheese.

Abstract: A method is provided that allows simultaneous control of macroscopic azimuthal and zenithal liquid crystal alignment (?, ?) across a liquid crystal layer by controlling the area ratios between first, second and third different types of alignment region (T1, T2, T3) in a patterned alignment layer, the three different types of alignment region (T1, T2, T3) tending to induce liquid crystal alignment in the liquid crystal layer in three different respective, non-coplanar, principal orientations (z, x, y). In the illustrated example, the first type of alignment region (T1) tends to induce substantially homeotropic alignment (in the z direction) and the second and third types of alignment region (T2, T3) tend to induce substantially planar alignment in different, orthogonal, principal orientations (in the x and y directions).

Abstract: A display device is provided that comprises a liquid crystal display panel for displaying an image by spatial light modulation, and circuitry for switching liquid crystal in the panel between having a first configuration in a first mode to cause an image displayed using the panel to be discernible from a wide range of viewing angles, and having a second configuration in a second mode to cause an image displayed using the panel to be discernible substantially only from within a narrow range of viewing angles. Several types of display panel to achieve such in-panel switching between public and private viewing modes are disclosed.
