Abstract: Red, blue and green lasers respectively emit a plurality of red, blue and green laser beams having respective output powers. The beams are optically focused and collinearly arranged to form a composite beam which is swept by a pair of scan mirrors in a pattern of scan lines on a projection surface, each scan line having a number of pixels. A controller causes selected pixels to be illuminated, and rendered visible, by the composite beam to produce an image. A safety circuit detects a malfunction of at least one of the lasers and the scan mirrors, and deenergizes the at least one of the lasers and the scan mirrors upon detection of the malfunction.

An imaging system has a plurality of camera assemblies coupled to an image processing system. Each camera assembly includes a sensor array and an imaging lens assembly for focusing a field of view of the camera assembly onto a sensor array as well as including one or more light emitting diodes for illuminating a field of view of that camera assembly. One camera is activated or energized to detect an object and then all cameras are activated for generating images suitable to decode a bar code on the detected object.

Abstract: The antenna of an RFID tag is automatically tuned by controlling both the real and imaginary components impedance “seen” by the antenna. The real component (resistive) is controlled by controlling a tap of a charge pump circuit of the tag. The imaginary (reactive) component is controlled by connecting one or more reactive elements of an antenna tuning circuit to the antenna. The real component is controlled by a first digital control loop that automatically activates successive taps on a charge pump of the RFID tag which effectively controls the resistance seen by the antenna. A second digital control loop controls the connection of the various reactive components.

Abstract: A multi-camera imaging-based scanner for imaging multiple target objects at substantially the same time and method is provided. The multi-camera imaging-based scanner comprises an image processing system with memory programmed to identify overlapping areas of field-of-views of the multiple cameras with in a scan field, such that if a target object is imaged by more than one camera at substantially the same time in one of the over lapping areas between two or more cameras' field-of-views, the processing system defines that a single target object has been detected and the decoded information therefrom is processed only once. If multiple target objects are imaged by more than one camera at substantially the same time outside of any of the over lapping areas between two or more cameras' field-of-views, the processing system defines that multiple target objects have been detected and the decoded information for each target object is processed.
