摘要： An automatically-activated wireless code symbol reading system comprising a hand-supportable housing having a manually-activatable data transmission switch under automatic communication range dependent control. When a bar code symbol is read, the bar code reader is located inside the predetermined RF data communication range of the system, then the symbol character data string, produced at substantially the same time as the manual activation of the data transmission switch, is transmitted to the base station over the wireless RF communication link. If the device is outside the range, then an audible and/or visual indication is automatically generated, and the packaged symbol character data string is packaged and transmitted to a data storage buffer aboard the bar code reader. Then when the bar code symbol reader is moved within the communication range of the system, the buffered/packaged symbol character data is automatically transmitted to the base station by the RF-based data communication link.

摘要： Methods of and systems for illuminating objects using planar laser illumination beams having substantially planar spatial distribution characteristics that extend through the field of view (FOV) of image formation and detection modules employed in such systems. Each planar laser illumination beam is produced from a planar laser illumination beam array (PLIA) comprising a plurality of planar laser illumination modules (PLIMs). Each PLIM comprises a visible laser diode (VLD), a focusing lens, and a cylindrical optical element arranged therewith. The individual planar laser illumination beam components produced from each PLIM are optically combined to produce a composite substantially planar illumination beam having substantially uniform power density characteristics over the entire spatial extend thereof and thus the working range of the system. Preferably, each planar laser illumination beam component is focused so that the minimum beam width thereof occurs at a point or plane which is the farthest or maximum object distance at which the system is designed to acquire images.
