    Abstract: A position sensing device having a single photosensing element is disclosed herein. The position sensing device determines the location of an object to which the position sensing device is attached relative to a surface. The position sensing device has a plurality of light paths that direct light from different area portions of the surface to the single photosensing element. Each area portion of the surface is associated with a light source wherein each light source may be activated individually. A processor illuminates these area portions individually. As the area portions are illuminated, the photosensing element creates image data representative of the image of the area portion being illuminated. The processor analyzes the image data and identifies distinct features in the area portions. As the object is moved relative to the surface, the locations of these distinct features relative to the photosensing element move. By measuring this movement, the processor is able to determine the velocity, direction of movement, and position of the object relative to the surface.

The optical component has an outer perimeter, and the optical bore sleeve has an inner perimeter for receiving the outer perimeter of the optical component. A plurality of deformable ridges are interposed between the outer perimeter of the optical component and the inner perimeter of the sleeve for aligning the optical component and the sleeve along a common optical axis as the ridges are deformed upon insertion of the optical component into the sleeve.

    Abstract: A stray light baffle for reducing an amount of stray light incident on a detector may comprise a main body portion and a mounting pad portion. The mounting pad portion is affixed to a mounting surface with a light curable adhesive. The stray light baffle substantially blocks stray light and substantially transmits curing light. The mounting surface is located adjacent the detector so that the main body portion of the stray light baffle is interposed between the detector and a source of stray light when the stray light baffle is mounted to the mounting surface.

    Abstract: A self-adjusting rock climbing anchor device includes at least one variable-length compression arm, at least one fixed-length load arm, a pivot element pivotally connecting the compression and load arms to one another, and at least one fixed-length follower cable. The follower cable interconnects the compression and load arms at intermediate locations thereon so as to form at least one four-bar linkage defined by the pivot element, the compression arm, the load arm and the follower cable, the follower cable. The movement of the compression and load arms between an unwedged and wedged condition provides for self-adjustment of the compression and load arms within the cleft and enables use of the compression and load arms in clefts of different sizes. The device further includes at least one spring which biases the compression arm toward a maximum length and thereby preloads the device to resist forces directed on the device from outside of a plane defined by the compression and load arms.

    Abstract: A microlens and microlens array which collect light incident upon image sensor pixels. The microlens comprises two parts one which collects light from the cross-sectional area lying over the light-detection area and the second which collects light from the corner areas of the pixel lying outside the cross-sectional area of the light-detection area. Light from each of the two areas is refracted onto an associated light-detection area. Essentially all of the light incident upon the pixel can thus be collected and refracted to the photosensitive area.

    Abstract: A line-focus system with a bulb in a bulb enclosure assembly, where the bulb has a lamp label attached to it in such a manner as to create an occluding aperture for directing light from the bulb toward the scan line in the line-focus system. The lamp label is shaped in such a manner that the light intensity across the photosensor line array in the line-focus system is relatively uniform. The lamp label is furthermore of an opaque, non-reflecting nature so as to prevent any stray light from being reflected into the line-focus system.

    Abstract: A beam splitter and method for separating a polychromatic light beam into a plurality of spatially and spectrally separated color component beams which are focused at a common image plane. The beam splitter includes a plurality of dichroic surfaces which each reflect light in a first spectral range, a second spectral range, or a third spectral range, and transmit light in spectral ranges other than the one it reflects. The beam splitter also includes a plurality of reflective surfaces which are each disposed parallel to one of the dichroic surfaces and which each reflect light in at least two of the first, second and third spectral ranges. The relative distances between the dichroic surfaces and corresponding reflective surfaces are such that the path lengths of the color component beams are approximately equal.

    Abstract: In embodiments of imaging structure color conversion, an imaging structure includes a silicon backplane with a driver pad array. An embedded light source is formed on the driver pad array in an emitter material layer, and the embedded light source emits light in a first color. A conductive material layer over the embedded light source forms a p-n junction between the emitter material layer and the conductive material layer. A color conversion layer can then convert a portion of the first color to at least a second color. Further, micro lens optics can be implemented to direct the light that is emitted through the color conversion layer.

    Abstract: A scroll wheel assembly for computer input device having a housing. The scroll wheel assembly includes a housing and an engagable scroll wheel. The scroll wheel is rotatable with a shaft to preferably cause vertical scrolling of an image on a display. The scroll wheel is laterally tiltable relative to the housing and the shaft. A sensor is preferably positioned within the housing for sensing tilting of the rotatable member. In response to sensed tilting movement of the rotatable member, the image is horizontally scrolled, preferably in the direction of the lateral movement. The computer input device having the rotatable member may take the form of a keyboard, a mouse, a trackball device, or another type of computer input device.
