    Abstract: A process comprises projecting a radiation beam (213) from a movable optical element (202) onto an image sensor positioned along an optical axis (210) of the movable optical element (202) and substantially normal thereto. The movable optical element (202) is movable relative to the image sensor (222) and the radiation beam is projected at a selected angle relative to the optical axis. A plurality of targets are positioned at known front focus distances from the movable optical element, and for each front focus distance, a back focal length of the movable optical element and the position where the beam of radiation falls on the image sensor are recorded.

    Abstract: An apparatus is disclosed comprising a base capable of receiving a camera including a lens, and a projector coupled to the base and adapted to project a plurality of beams of light onto a plane positioned at a focus distance from the base, wherein the projections of the beams of light on the plane are geometric shapes, and wherein an intersection of the geometric shapes is at the center of the field of view of the lens when the lens is installed on the base. In addition, an apparatus is disclosed comprising a base capable of receiving a camera including a lens, an image processor capable of being coupled to the camera for processing an image of a target captured by the camera, and a confirmation projector coupled to the image processor, wherein the projector projects a confirmation beam onto the plane of the target when the image processor signals the confirmation projector that it has processed the image.

    Abstract: A PROGRESSIVE-SCAN CHARGE-COUPLED DEVICE (PSCCD) CAMERA MAY CAPTURE AN ENTIRE FRAME OF AN IMAGE OF AN OPTICALLY READABLE CODE. THE CAMERA GENERATES A HISTOGRAM OR PROBABLY DISTRIBUTION FUNCTION (PDF) OF THE IMAGE AND USES THE HISTOGRAM OR PDF TO AUTOMATICALLY ADJUST THE CONTRAST OF THE IMAGE. THE CAMERA ALSO GENERATES A CUMULATIVE DISTRIBUTION FUNCTION (CDF) WHICH IS USED TO AUTOMATICALLY ADJUSTTHE ILLUMINATION INTENSITY INCLUDING THE BRIGHTNESS OF THE IMAGE AND THE DURATION OVER WHICH THE IMAGE IS OBTAINED. THE CAPTURED ANALOG VIDEO IMAGE IS CONVERTED TO A DIGITAL VIDEO IMAGE WHICH MAY BE OUTPUT OVER THE CAMERA''S BIDIRECTIONAL BUS INTERFACE TO A COMPONENT OUTSIDE OF THE CAMERA. UPDATED PROGRAMS, PARAMETERS AND OTHER INFORMATION MAY BE SENT IN THE OPPOSITE DIRECTION OVER THE BUS INTERFACE TO THE CAMERA. THE CAMERA MAY BE MOUNTED AT A FIXED STATION OR MAY BE INCORPORATED INTO A PORTABLE UNIT, AND MAY BE HAND-HELD AND/OR BATTERY OPERATED.FIGURE 2

    Abstract: The disclosure describes an apparatus and method for automatic gain control during scanning. The apparatus comprises an optical detector (206) to receive an optical signal reflected from a symbol (214) positioned within a scan window (215) by an optical beam (212) scanned from a leading edge (218) of the scan window (215) to a trailing edge (220) of the scan window; and a processor coupled (208) to the optical detector to adjust the gain of the optical detector during the beam scan. The process comprises receiving an optical signal using an optical detector (206), wherein the optical signal comprises optical energy reflected from a symbol positioned in a scan window as an optical beam scans from a leading edge of the scan window to a trailing edge of the scan window, and adjusting the gain of the optical detector during receipt of the optical signal. A calibration process is disclosed comprising calibrating the optical detector to obtain a plurality of gain corrections, each gain correction corresponding to a different position between a leading edge and a trailing edge of a scan window, and storing the plurality of gain corrections.

    Abstract: The present invention provides a micromechanical or microoptomechanical structure. The structure is produced by a process comprising defining a pattern on a single crystal silicon layer separated by an insulator layer from a substrate layer; defining a structure in the single-crystal silicon layer; depositing and etching a polysilicon layer on the single crystal silicon layer, with remaining polysilcon forming mechanical or optical elements of the structure; and releasing the formed structure.
