Abstract: A laser beam experimentation kit, including an accessory device for modulating the intensity of the visible laser beam produced as output from a laser pointer. The accessory device comprises a printed circuit(PC) board of physically thin construction, which is adapted for slidable insertion between the conductive tip portion and the conductive housing portion of a pen-clip actuatable laser pointer. A pair of conductive pads are formed on the upper and lower surfaces of the PC board. An input signal jack is mounted on PC board for the purpose of receiving a mated plug connector that is connected to a flexible cable carrying an electrical input signal. An electronic circuit and a battery power source are also mounted on the upper surface of the PC board. The function of the electronic circuit is to respond to a predetermined signal characteristic (e.g., the amplitude, frequency or phase) of the input signal supplied to the input signal jack, and to provide a variable load between the pair of conductive pads formed on the PC board. In this way, when the PC board is slidably inserted between the conductive tip portion and the conductive housing portion of the pen-like housing of the laser pointer, the pair of conductive pads on the PC board automatically establish electrical contact therewith without problems of alignment or the like. During joint operation of the laser pointer and the accessory device, the impedance of the variable load varies in response to variations in the predetermined signal characteristic of the electrical input signal. Such variations in the impedance of the variable load automatically modify the flow of electrical current through the laser diode in the laser pointer and thus modulates the intensity of the laser beam in accordance therewith.

Abstract: Method and apparatus for automatically reading bar code symbols is disclosed. One aspect of the present invention concerns a method of reading bar code symbols using an automatic hand-holdable bar code symbol reading device. In general, the automatic bar code symbol reading device comprises a hand-holdable housing containing operative elements which provide an object detection field and a scan field each defined external to the housing. The method involves automatically detecting the presence of an object within the object detection field by sensing energy reflected off the object. In a preferred embodiment, the object sensing energy is IR radiation produced from an energy reflects off the object source disposed within the housing. In automatic response to the detection of the object within the object detection field, the hand-holdable device detects the presence of a bar code within the scan field using a laser beam produced within the housing. Then, in automatic response to the detection of a bar code in the scan field, the automatic hand-holdable bar code symbol reading device reads the detected bar code in the scan field by producing scan data signals from the detected bar code and thereafter collecting and analyzing the same. Another aspect of the present invention concerns a hand-holdable data collection device adapted for use with the automatic bar code symbol reading device to form a portable symbol reading system characterized by versatility and simplicity of use.

Abstract: Disclosed is an automatically-activated wireless code symbol reading system comprising a bar code symbol reading mechanism contained within a hand-supportable housing having a manually-activatable data transmission switch. During symbol reading operations, the bar code symbol reading mechanism automatically generates a visible laser scanning pattern for repeatedly reading one or more bar code symbols on an object during a bar code symbol reading cycle, and automatically generating a new symbol character data string in response to each bar code symbol read thereby. During system operation, the user visually aligns the visible laser scanning pattern with a particular bar code symbol on an object (e.g. product, bar code menu, etc.) so that the bar code symbol is scanned, detected and decoded in a cyclical manner. Each time the scanned bar code symbol is successfully read during a bar code symbol reading cycle, a new bar code symbol character string is produced, while an indicator light on the hand-supportable housing is actively driven. During the bar code symbol reading cycle, the user actuates the data transmission switch producing a data transmission control activation signal and enabling a currently or subsequently produced symbol character data string to be automatically selected and transmitted to the host system. By virtue of the present invention, automatically-activated hand-supportable bar code symbol readers are now able to accurately read, in an unprecedented manner, bar code symbols on bar code menus, consumer products positioned in crowded point-of-sale environments, and other objects requiring automatic identification and/or information access.

Abstract: 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 an 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 laser 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, thereby compensating for decreases in the power density of the incident planar laser illumination beam due to the fact that the width of the planar laser illumination beam increases in length for increasing object distances away from the imaging optics. By virtue of the present invention, it is now possible to use both VLDs and high-speed CCD-type image detectors in conveyor, hand-held and hold-under type scanning applications alike, enjoying the advantages and benefits that each such technology has to offer, while avoiding the shortcomings and drawbacks hitherto associated therewith.
