摘要： 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.

摘要： An imaging device for generating a digital image of a scene comprises an image sensor, an optic, and one or more actuators. The image sensor comprises an array of photosensors. The optic is operative to at least partially direct light rays from the scene onto this image sensor so that an image of the scene is created on the image sensor. The one or more actuators are operative to move at least one of the image sensor and the optic while the digital image is generated so that the incoming light rays from the scene are distributed over the photosensors of the image sensor in such a way as to limit spatial frequencies in the image of the scene created on the image sensor to values below a Nyquist frequency of the image sensor.

摘要： A dual resolution printer for printing images on an associated print medium includes: a light source providing a light beam and a focusing lens focusing the light beam and creating a converging light beam having at least one beam waist of at least one wavelength at a first beam waist location. The printer also includes an optical unit movable in and out of the converging light beam and having a corresponding first and second position, respectively. This optical unit, in the second position, reimages the beam waist of the converging light beam created by the focusing lens to a different size second beam waist, at a location substantially the same as the first beam waist location.

摘要： A loom is provided with a closed path for the weft yarn from a yarn package to a picking nozzle. A first yarn guiding passage extends from a yarn clamp to a weft yarn storage device while a second yarn guiding passage extends from the storage device to the picking nozzle. Sensors are disposed along the path of the yarn in order to sense the presence or absence of a thread for searching/rethreading purposes. The second yarn guiding passage is articulated to the storage device and the picking nozzle in order to follow movements of the picking nozzles relative to a reed.

摘要： Apparatus for turning the end of a weft yarn into a warp shed for creation of a selvedge, the apparatus including a movable guide which in a first position is located outside the warp sheet to receive the end of a weft yarn after weft insertion, and which is movable to a second position located within the warp shed whereby the guide serves to separate the end of the weft yarn from the warp threads. A fluid jet nozzle is associated with the guide and is positioned to direct a flow of fluid along the guide, after the guide is moved inwardly to the second position, for carrying the end of the weft yarn into the warp shed.
