Decoding of barcodes by preprocessing scan data

Scanned barcodes represented by an electrical signal are preprocessed in a PLA and delivered to a microprocessor in a form that permits efficient final processing of the data. High speed edge detection produce edge markers for the control logic and counting circuits coupled with a Johnson state counter to logically sequence the processor. Logarithmic conversion compresses the counted time interval to a single data word that can most efficiently be processed by the host microprocessor. Logic between the preprocessor and the microprocessor transfer digital representations of each bar and space to preassigned respective areas in the microprocessor memory. Bar/space margin detection performs a ratiometric comparison of each bar and space to determine every occurrence of 10:1 ratios of both bar/space and space/bar. Pointer signal information is transferred to the microprocessor indicating precisely where in memory each 10:1 margin ratio is located. A digital filter excludes spurious bar/space width in the preprocessor.

The process comprises receiving an optical signal using an optical detector (206), wherein the optical signal comprises optical energy reflected from a symbol positioned in a scan window as an optical beam scans from a leading edge of the scan window to a trailing edge of the scan window, and adjusting the gain of the optical detector during receipt of the optical signal. A calibration process is disclosed comprising calibrating the optical detector to obtain a plurality of gain corrections, each gain correction corresponding to a different position between a leading edge and a trailing edge of a scan window, and storing the plurality of gain corrections.

Smart progressive-scan charge-coupled device camera

A PROGRESSIVE-SCAN CHARGE-COUPLED DEVICE (PSCCD) CAMERA MAY CAPTURE AN ENTIRE FRAME OF AN IMAGE OF AN OPTICALLY READABLE CODE. THE CAMERA GENERATES A HISTOGRAM OR PROBABLY DISTRIBUTION FUNCTION (PDF) OF THE IMAGE AND USES THE HISTOGRAM OR PDF TO AUTOMATICALLY ADJUST THE CONTRAST OF THE IMAGE. THE CAMERA ALSO GENERATES A CUMULATIVE DISTRIBUTION FUNCTION (CDF) WHICH IS USED TO AUTOMATICALLY ADJUSTTHE ILLUMINATION INTENSITY INCLUDING THE BRIGHTNESS OF THE IMAGE AND THE DURATION OVER WHICH THE IMAGE IS OBTAINED. THE CAPTURED ANALOG VIDEO IMAGE IS CONVERTED TO A DIGITAL VIDEO IMAGE WHICH MAY BE OUTPUT OVER THE CAMERA''S BIDIRECTIONAL BUS INTERFACE TO A COMPONENT OUTSIDE OF THE CAMERA. UPDATED PROGRAMS, PARAMETERS AND OTHER INFORMATION MAY BE SENT IN THE OPPOSITE DIRECTION OVER THE BUS INTERFACE TO THE CAMERA. THE CAMERA MAY BE MOUNTED AT A FIXED STATION OR MAY BE INCORPORATED INTO A PORTABLE UNIT, AND MAY BE HAND-HELD AND/OR BATTERY OPERATED.FIGURE 2

Generic data exchange method using hierarchical routing

A process including retrieving a list of one or more candidate objects with which an origin object can communicate using a standard command language, wherein at least one of the one or more candidate objects uses a command language different than the standard command language. The process queries the schema of one or more target objects selected from among the one or more candidate objects and uses the standard command language to transmit to the one or more target objects commands and/or data consistent with the schemas of the target objects.

Illumination system with side-emitting illumination, targeting, and confirmation

Embodiments are disclosed of a lighting apparatus including a fixture adapted to accommodate a camera having imaging optics that define an optical axis, wherein the fixture includes an open end through which the imaging optics can capture an image. One or more side-emitting illumination light sources are positioned adjacent to the open end, the plurality of side-emitting light sources positioned to direct light toward a plane intersected by the optical axis. Other embodiments are disclosed and claimed.

Illumination system

Implementations of an apparatus including a housing having therein at least one light source, the at least one light source oriented to direct light out one side of the housing, and an arc-shaped reflector connected to the housing, the arc-shaped reflector having a reflecting surface optically coupled to the at least one light source to reflect light from the at least one light source to a position adjacent to the housing.
