Abstract: An optical navigation device that can sense the movement of an object, such as a user's finger, so that the movement can control a feature of a consumer digital device such as a cursor on a display screen. The device includes a substrate to which an LED, reflector, and image sensor are attached. Light from the LED is directed by the elliptical reflector toward and through a window that is transparent to the light from the LED and then is reflected off of the user's finger back through the window, through a lens, and onto the image sensor. The reflector is positioned to direct light toward the window at an oblique angle, in the range of 65 to 70 degrees from an angle normal to the window. Further, the reflector is curved to gather light across a large solid angle in the vicinity of the LED. The curved shape of the reflector may be a portion of an ellipsoid and the LED may be located at one of the foci of the ellipsoid, with the window located at the other foci of the ellipsoid.

Abstract: Imaging systems and methods for calibrating imaging systems are provided. The imaging system has a body, a scene image capture system that captures images using a taking lens system that can be set to a plurality of different focus distances, and a rangefinder that is capable of determining a distance between the imaging system and at least one portion of a field of view of the taking lens system. The method comprises: automatically capturing a first calibration image of a first field of view through the taking lens system with the taking lens system set to a first focus distance setting; identifying a portion of the first calibration image having a predetermined degree of focus; using the rangefinder to determine a first calibration distance from the imaging device to the identified portion. A focus correlation is determined based upon the first calibration distance and the first focus distance setting.

Abstract: An f-.theta. lens is disclosed which is particularly suitable for use with a color laser printer in which beams of different wavelengths are combined into a single light beam. The combined light beam is scanned by a rotating polygon onto a receiving medium. The f-.theta. is adapted to operate with 1.) beam shaping optics for shaping the beam in a scan direction prior to the polygon, and 2.) a cylindrical element located behind the f-.theta. lens, to image the light beam in a cross-scan direction onto the receiving medium. The f-.theta. lens includes a plurality of lens components. The lens components cooperate to (a) focus a received combination beam of three different wavelengths onto an image surface, the received combination beam having different vergences and different waist locations in the page and line directions, the vergences and the waist locations being substantially the same in each of the three wavelengths; and (b) compensate for chromatic aberration. This compensation renders the f-.theta. lens an achromatic lens for axial color in both scan and page directions at the image surface. According to the preferred embodiment of the present invention, the .theta. lens is an apochromatic lens with regards to the axial color. The lateral color is corrected electronically.

Abstract: A cam actuator for selectively moving cam elements axially between distinct operative positions in a circular knitting machine, the actuator including a series of adjacent pistions arranged along the axial line of displacement, and stop means for limiting the axial stroke of each piston in the direction of extension. Each piston co-operates with adjacent pistons in the series such that displacement of a given piston in the extend direction causes the remaining pistons located between the cam element and the given piston to be displaced in the extend direction by the stroke length undergone by the given piston.
