A high capacity battery charger includes multiple sockets to connect to a variety of different battery-receiving adapters. Each socket includes a multi-slot female connector and a planar flange that surrounds the connector for securing to a wiring harness and the top support deck of the charger chassis. A pivoting latch facilitates plugging and unplugging the multi-blade adapters into the sockets. An electromagnetic shield covers the power supply and includes a wing extending toward the central axis of a cooling fan.

A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional or two-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edges of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.

Various optical components of an electro-optical system for reading coded indicia are mounted on a chassis snap-mounted in a housing. The optical components are supported by the chassis at an elevation relative to a printed circuit board snap-mounted to the chassis. The optical components are automatically adjusted in a test fixture.

A lightweight, easy to grasp and manipulate hand-held optical scanning device for scanning and digitizing image data from a two-dimensional bar code symbol for subsequent decoding in a personal computer platform. The scanning device achieves a small footprint in the user's workspace by utilizing a non-folded, substantially vertical optical path extending from an image viewing area upwardly to a linear charge-coupled device (CCD) array upon which the successive rows of the target two-dimensional bar code symbol are imaged. The scanning device is easily aligned with the symbol by placing it behind the symbol, and scanning of the successive rows of the symbol is accomplished by swiping or rolling the scanning device towards the user. Mechanical rollers on the underside of the scanning device provide translation information for use in clocking data out of the linear CCD array in order to scan the successive rows of the two-dimensional bar code symbol. The operating environment of the computer allows scanning to be initiated by the user without having to use the keyboard or mouse peripheral. As the two-dimensional bar code symbol is being scanned, digitized image data is automatically and in real time ported to a symbol decoding application running in the background, and decoded data from the decoding application is ported into the application the user is running in the foreground. A trackball and a pair of select buttons are optionally provided on the scanning device for mouse emulation, thereby eliminating the need for a separate mouse peripheral device.

Hand-held optical scanner for reading two-dimensional bar code symbols

An interface between a two-dimensional bar code scanner and a host digital decoder is provided through a 15-pin electronic connector, which transfers to the decoder an actuating signal either from a scanner trigger switch or from an external device. In response, the digital decoder provides the scanner with operating power. The scanner generates and relays a bar code signal and a scanning direction signal back to the digital decoder, which uses these signals to identify a bar code being scanned as a one-dimensional or two-dimensional code. If the bar code is determined to be a two-dimensional code, upon detection of laser pattern alignment with the label the digital decoder sends a scanning control signal to the scanner to control a laser pattern generated by the scanner.

Two-dimensional bar code scanner interface

A scanner interface is operatively connected to an electro-optical scanner for scanning bar code symbols. A status/condition interface is operatively connected with a system component, e.g., a photodetector, a decoder, a battery, etc., whose status/condition is to be monitored. Threshold information about the system component is stored in a memory. A system processor generates updated information about the system component during scanning, compares the updated information with the threshold information and generates an output signal upon such comparison. In response to the output signal, an indicator signals a user as to the status/condition of the system component.

A microprocessor-controlled device with software files stored in non-volatile memory which can be easily modified by the user by reading or scanning a two-dimensional bar code symbol having program modification information encoded thereon. The symbol can be read by two-dimensional or one-dimensional laser or CCD based means. Depending on its size, either the entire file can be replaced, selected locations can be replaced, or selected relocatable object files can be linked at the target device in order to effect the program revision.

A system and method for capturing hand-marked cells from a lottery selection slip. The lottery slip includes a conventional play region of cells (labelled sequentially from 1 to 49, for example) for receiving indicia to be captured, after receiving indicia said play region of cells includes a plurality of occupied cells defined by marked cells and a plurality of non-occupied cells defined by unmarked cells. The lottery slip also includes row-identifier bar codes located at opposite boundaries of the play region. The bar codes are electro-optically scannable and readable and are arranged in a plurality of ordered rows tiered along the transverse direction over the transverse distance of the play region. A scanner is used to generate scan lines that extend over the play region of cells occupied by the indicia and over each bar code and for decoding the row identifer data for each scan line as each line transverses the boundaries of the play region of cells, the occupied cells having different light reflectivity than the non-occupied cells. A decoder captures the identity and the location of the occupied cells and the non-occupied cells and stores the digitized signal. A ticket receipt is then issued representative of the numbers selected by the player. By using a bar code scanner to read both the row identifier codes and the actual hand-marked play region the need for precise positioning within traditional terminals is obviated.

A method and apparatus for increasing the information density of a bar code symbol by generating multiple constituent bar code symbols, wherein each one is formed in a different color selected from a group of various primary colors, and overlaying each differently colored symbol on top of each other, thus forming an aggregate bar code symbol of various colors. In areas where the differently colored bars overlap each other, colors distinct from those in the original group of colors are formed. The aggregate bar code symbol is scanned by a solid state imaging device, and the scanned image is resolved by image processing techniques into the three constituent bar code symbols of the various colors. Each bar code symbol is then individually processed and decoded in accordance with the particular symbology used to encode the constituent bar code symbols. As a result of the present invention, multiple bar code symbols are printed in the space normally required by one bar code symbol, and each constituent symbol is separated by color resolution and decoded to form the original data. Thus, the information density of the bar code system is increased without the need for a new symbology. In addition, a single bar code symbol may be divided into multiple portions of substantially the same size and printed substantially over each other in different colors, thus producing a single compacted bar code symbol with increased information density. The compacted bar code symbol may be recovered by scanning and resolving the symbol back into its constituent portions, concatenating the portions together, and decoding the resulting bar code symbol in accordance with standard techniques.
