Title: Foldable stepped display stand having shelves with open sides
Inventor: MINISTER DAVID BRIAN
IPC: A47F7/14
Filed: 2003-06-13
Abstract: A foldable display stand having three opened side shelves is formed by two stepped side panels, a front panel, and a rear panel which are formed from a single geometrical figure formed in a single sheet material. The stand is foldable into a collapsed condition relative to two vertical fold lines formed on the side panel and located opposite to one another. The front panel will abut the rear panel when the stand is folded in the collapsed condition. The shelves are formed by a plurality of panels formed in an upper extension to the front panel and the rear panel. These panels are foldable relative to horizontal fold lines to form the three shelves resting horizontally on stepped upper edges of the side panels. Open end slots are formed in a free end edge of end panels of the front panel and rear panel, which are engageable with upper edges of the side panels for latching the opened side shelves securely in the horizontal position.

Title: Highly efficient projection system and color scrolling method therefor
Inventor: CHO KUN-HO
IPC: G02B27/18
Filed: 2003-09-03
Abstract: A highly efficient projection system and a color scrolling method are provided. In the color scrolling method, first, an optical splitter splits a beam emitted from a light source into individual color beams. Next, a rectangular light valve is disposed such that its long axis is along the direction into which the optical splitter splits the beam.

Abstract: A cooking appliance includes a cooktop having at least one heating element and a controller capable of automatically performing a cooking process by operating the heating element at multiple power levels for multiple time periods. More specifically, upon activation, a consumer, through manipulation of a control, can select an initial power level and an initial time duration for the initial power level. Once the initial power level is selected, a second power level and second time duration may be selected. With this arrangement, the controller will operate the heating element at the initial, high power level for the first time duration. Once the initial time period has elapsed, the controller automatically lowers the temperature of the heating element to finish the cooking process for the second time duration.
