Abstract: A method includes displaying a listing of content items in a first display area and displaying supplemental content items related to at least one of the content items in a second display area that is separate from the first display area. The listing of content items may represent content items that are available for rendering on a content rendering device. The listing of content items and the supplemental content items may be displayed simultaneously. One of the displayed content items may be selected and in response, the displayed listing of content items may be swapped to the second display area and the displayed supplemental content items may be swapped to the first display area.

Abstract: An encode device, comprises a light source, an encode wheel and a light detector. A hollow dent is formed on the center part of the incident plane of the encode wheel. The inner circumference of the dent is provided with a ring-shaped lens such that the light impinging on the inner circumference of the dent is focused by the ring-shaped lens. The rim of the encode wheel is provided with a plurality of cylindrical lenses which are perpendicular to the ring-shaped lens such that the light leaving the encode wheel can be further focused. Therefore, the working beam projected toward the chip of the light detector has less interference.

Abstract: Disclosed is an automatic controlled multi-level storage system having a bottom access level, a plurality of cargo storage levels vertically spaced above the access level, and a central elevator space vertically disposed through each level, each level having an array of contiguous spaces mounted with four-way or two-way wheel assemblies longitudinally and/or transversely and pairs of parallel rails intersected with one another longitudinally and transversely for moving individual storage platforms and cargo thereon, the elevator space being installed with an elevator for raising and lowering individual storage platforms and cargo thereon to a desired level, the elevator having two register spaces vertically spaced, each resister space having four-way wheel assemblies and mechanical arms for moving each time an individual storage platform to either level, the access level having platform storage devices for storing individual storage platforms.

Abstract: A computer-controlled, multi-floor, multi-block equipment conveying and storage system having a multi-floor steel framework made of H-beam steels. Each floor is divided into a plurality of equal blocks longitudinally and latitudinally aligned. The blocks include one block serving as a lifting gear access unit for the passing therethrough of a lifting gear which moves from floor to floor for carrying storage items and the other blocks serving as storage units surrounding the lifting gear access unit for storing items. A plurality of driving mechanisms to separately carry a plurality of carrier plates from block to block in a straight direction permits any designated carrier plate in either floor to be moved to the lifting gear access unit of the same floor for delivery to any other floor by the lifting gear.
