Abstract: Alignment structures are included in high-speed data cage assemblies to prevent damage to one or more electronic components connected within the cage assembly and prevent misalignment of connected components. The alignment structures extend inwardly into a port and prevent movement of a module beyond the intended position of the module in a port. This allows connection between the module and a connector and prevents misalignment of the module. Damage to either the module or the connector by misalignment or by over-insertion of the module is prevented.

Abstract: A signaling control device apparatus (10) comprises at least one LED (20) having a light emitting surface (18). A sensor (24) is set to detect an external light load (16) directed to the light emitting surface (18) and generate a control signal indicative of a presence of the light load (16). An electrical control system (14) detects the control signal indicative of the light load (16) and sources an elevated current to the LED (20) while the light load (16) is present. The elevated current increases the contrast ratio making the signal perceivable by the users as being in a particular state.

Abstract: Disclosed information exploration system and method embodiments operate on a document set to determine a document cluster hierarchy. An exclusionary phrase index is determined for each cluster, and representative phrases are selected from the indexes. The selection process may enforce pathwise uniqueness and balanced sub-cluster representation. The representative phrases may be used as cluster labels in an interactive information exploration interface.

Abstract: The present invention provides a disposable plate (10) with a handle portion (15) along a portion of its circumference, said disposable plate capable of being stacked upon like disposable plates to form a stack (20), which handle portion provides support for holding the plate and means for taking hold of and separating the plate when stacked with other disposable plates. One aspect of the invention provides an apparatus and method of nesting or stacking a plurality of disposable plates together to form a stack (20), wherein the handle portions of such disposable plates are circumferentially spaced or staggered such that no handle portion (e.g., 24A, 24B, 24C) rests substantially upon the handle portion of the plate immediately adjacent to it in the stack, to permit efficient separation of such disposable plates.

Abstract: A lamp (10) includes a substrate (12), a first lighting unit (14A) and a second lighting unit (14B). The first lighting unit (14A) includes a first light emitting diode (22A) arranged on the substrate (12), and a first lens element (24A) that has a first optical prescription and is arranged to interact with light produced by the first light emitting diode (22A). The second lighting unit (14B) includes a second light emitting diode (22B) arranged on the substrate (12), and a second lens element (24B) that has a second optical prescription and is arranged to interact with light produced by the second light emitting diode (22B). A means (30) for selectively applying electrical power has at least a first selectable mode in which the means (30) applies power to the first lighting unit (14A) whereby a first light output pattern is emitted, and a second selectable mode in which the means (30) applies power to the second lighting unit (14B) whereby a second light output pattern is emitted.

Abstract: A lighting apparatus (10) includes a wave guide (14) formed from a translucent material. The wave guide has a top surface (30), a bottom surface (32) that has a pre-defined curvature, and at least one side surface (34) that receives light (40) injected therein. A plurality of microstructures (36) are arranged on selected areas of the bottom surface (32) of the wave guide (14). The plurality of microstructures (36) cooperates with the pre-defined curvature of the bottom surface (32) to scatter at least a portion of the light (40) injected into the at least one side surface (34). The scattered light (42) exits the wave guide (14) through the top surface (30). At least one light emitting diode (16) injects light (40) into the at least one side surface (34) of the wave guide (14). The scattered light (42) that exits the wave guide (14) forms at least one symbol viewable by an associated observer.
