摘要： Products associated with targets to be read by image capture are processed in a workstation having a window, a solid-state imager looking at a field of view extending through the window to a target to be imaged, and an illumination system for illuminating the field of view. A proximity system detects a product associated with the target in a selected zone outside the window. The proximity system has an infrared (IR) emitter for emitting IR light into an IR emission field, and an IR sensor for sensing return IR light within an IR detection field that intersects the IR emission field in the selected zone. A controller energizes the illumination system in response to the detection of the product in the selected zone, and processes return illumination light captured in the field of view by the imager.

摘要： An apparatus for, and method of, imaging printed and electronic codes associated with transactions or objects to be processed, support a window on a housing, illuminate the codes through the window with illumination light from an energizable illumination system, capture return illumination light from the illuminated codes through the window with an array of light sensors looking at a field of view of a solid-state, exposable imager, and process the captured return illumination light. A printed code is read by exposing the imager for a first exposure time and by also energizing the illumination system during the first exposure time. An electronic code is read by exposing the imager for a second exposure time that is longer than the first exposure time and by also deenergizing the illumination system during the second exposure time.

摘要： A lensholder holds at least one fixed optical lens and a variable focusing element in a spaced relation along an optical path through which light passes in an electro-optical reader. The variable focusing element has a pair of electrodes across which a voltage is applied to optically modify the light passing through the fixed optical lens and the variable focusing element. The lensholder directly electrically conductively contacts the electrodes and establishes an electrically conductive path between each electrode and an exterior of the lensholder.

摘要： A method and apparatus are provided to capture images using a laser projection display (LPD). In a full color LPD camera, three lasers (red, blue, and green) are deployed to scan an image and receive reflected laser light therefrom. The reflected laser light may be analyzed and assembled into a picture. The LPD may also be used to display the picture, to operate as a viewfinder, to print the picture, to operate as a range finder, and the like.

摘要： A method and apparatus are provided to controllably reduce power of a laser projection display (LPD) in response to detecting a variation in a viewing surface. During the operation of the LPD, a controller 142 monitors laser light being reflected from the viewing surface. Since the controller 142 “knows” the amount of power that the LPD is being instructed to deliver, it may compare the known power to the reflected laser light to determine if a foreign object may be in the path of the laser light, and therefore, affecting the magnitude of the laser light. The controller 142 responds to detecting such an event by reducing power to the lasers.
