Abstract: An optical scanning system is provided for producing a signal representative of a spatial distribution of indicia having different degrees of reflectivity to light, such as a bar code (14). The system includes an optical scanner (12) for scanning beam of light over the spatial distribution of indicia (14) and for producing an electrical signal corresponding to changes in the degree of reflectivity of the indicia. A digitizer (20), responsive to detections in a predetermined characteristic of the produced electrical signal is provided. The digitizer (20) converts the detections into digital words, such digital signals having a plurality of bits. The digitizer includes a timing generation circuit (42) for producing a pulse in response to each one of the detections with a time duration representative of the degree of reflectivity of the indicia as the beam of light. A decoder converts the time duration of the pulse into the digital word having a plurality of bits. An enhancement filter (30) is also disclosed.

Abstract: An optical scanner with plural scan beam generation. Scan angle stress is configured in the beam generation.

Abstract: An optical scanner for reading indicia of variable light reflectivity, such as bar code symbols, having a light source for producing a light beam for scanning a target; a sensor for collecting the reflected light from the target; and various light collection systems, including a louver formed from an array of thin slats positioned adjacent to the sensor so that light directed along substantially only one angle reaches the sensor, as well as imaging/diffusing optical systems.

Abstract: A scanning device incorporates a vertical cavity surface emitting laser (VCSEL). The laser diode may be mounted directly on an Si substrate which is adapted for movement to produce a scan pattern. A collimating lens may be directly mounted on the emitting surface of the laser. A plurality of lasers may be mounted on the substrate and operated in sequence without movement of the substrate to produce the effect of a scan. The scanning device emits visible or invisible light towards a target such as a bar code and a detector (mounted on the same or an adjacent substrate) senses the light reflected by the target to produce data which is decoded for further processing. A VCSEL uses low current and emits light from a relatively large area so that a relatively large amount of light is emitted for relatively small heat generation.

Abstract: A bar code reader for reading a symbol located at a distance from the laser comprises an array of groups of reading elements and an array of selectable liquid crystal elements. Each of the groups of reading elements have an associated predetermined operating focal distance. At least one liquid crystal element corresponds to each group of reading elements. In the bar code reader, a device activates a selected liquid crystal element to transmit light to a selected group of reading elements. In this way, the reading elements can operate at a predetermined, fixed operating focal distance.

Abstract: A reader generates a scanning beam for reading a bar code symbol on a selected item. The reader includes a motion sensor or software program for discriminating between the selected item and other items also having bar code symbols thereon. The motion sensor or software program for discriminating between the items may discriminate between an item swept past the reader and stationary items, or an item moved into the field of view of the reader, held stationary and moved out of the field of view and stationary or moving items or between an item placed within a predetermined distance range and other items.

Abstract: A record carrier (e.g., an identification card) of the type containing machine-readable representations of data, wherein the record carrier comprises a substrate, a first pattern of machine-readable indicia applied to one surface of the substrate, and a hologram containing machine-readable data disposed on one surface of the substrate. The information represented by the machine-readable indicia and the machine-readable data are related to one another so as to enable a user to verify the authenticity of the record carrier by comparison of the indicia and the data.

Abstract: A bar code reader system includes a record, a bar code reader, a decoder, a processor, a transferring element, and a printer. The record includes a substrate with an information area containing first data removably encoded on the substrate in an error-correctable machine readable format and text. The bar code reader converts the first encoded data from the record into electrical signals which are decoded by the decoder. The processor encodes second data entered through a keyboard, and generates transfer drive signals for controlling the transfer of the second encoded data onto the record. The transferring element detects the presence of the first encoded data on the record, and in response to the drive signals when the first encoded data is present on the record, subjects the record to an erasing operation to remove the first encoded data. The printer then prints the second encoded data on the record.

Abstract: A system for reading indicia such as bar code symbols having a scanner for generating a scanning light beam directed toward a symbol to be read; a first actuator manually displaceable from a first position to a second position for producing a first light beam for aiming or positioning the reader, and a second actuator manually displaceable from a first position to a second position for initiating a scanning beam pattern for reading the symbol. The actuators are independently operative of each other. A detector receives the reflected light from the symbol and produces electrical signals corresponding to data represented by the symbol. A graphical user interface with icons simplifies system control functions.

Abstract: A reader generates a scanning beam for reading a bar code symbol on a selected item. The reader includes a database in which codes for all symbols to be read are stored, and frequency of use data indicative of how often each stored code has been read. A processor compares the code of the symbol being scanned with the stored codes. Upon a successful comparison, the code is processed as a valid code. Upon failure to match the code to one of the stored codes, a most likely code is selected as the valid code. The most likely code is based on the frequency of use data.

Abstract: A printing and reading system prints records having two-dimensional erasable bar codes. The bar code is printed on the record in erasable ink and can be implemented in PDF417 format. The system reads the two-dimensional erasable bar code located on the record, erases it using erasing fluid, dries it, and prints a new two-dimensional erasable bar code in place of the previous two-dimensional erasable bar code.

Abstract: A portable terminal has a housing with a motion detector housed therein. Movement of the housing from a a rest position is detected by sensing the motion of a coil or magnet located within the housing. A controller activates circuitry within the housing responsive to the detected movement. The terminal may include a touch sensitive display, on a flat front surface of the housing. A light emitter and an optical detector may also be disposed within the housing. Preferably, the terminal also houses a sensor for sensing different specific positional orientations of the terminal and activating or deactivating terminal functions depending on the sensed orientation.
