Filed:

Nov 23, 1998

Appl. No.:

09/198125

Inventors:

Brent G. Robertson - Richardson TX
Glenn W. Lee - Plano TX
Roger J. Colburn - Plano TX

Assignee:

Informatics, Inc. - Plano TX

International Classification:

G06K 710

US Classification:

2354621, 23546216, 23546211

Abstract:

A method and apparatus for decoding two-dimensional barcode symbols from a data stream generated by scanning a two-dimensional barcode with a one-dimensional scanner. A decoding process according to one embodiment of the invention involves coupling the one-dimensional scanner to a serial or other port of a host computer in order to provide a data stream to a software decoder resident in the host computer. The software decoder performs a series of iterative steps in which the data stream is sampled at regular intervals to convert the data stream to a series of elements (e. g. , bars and spaces). Barcode symbol data characters are then derived from the elements. A symbol matrix is next constructed, the matrix being representative of the two-dimensional barcode symbol.

H04N 7173

US Classification:

710 38

Abstract:

A method and apparatus for processing data in a computer system from a keyboard wedged device and a keyboard hook device. The keyboard wedge converts the data into standard keyboard keystrokes for transmission over a keyboard line. The keyboard hook provides a window through which scanned data is detected. Scanned data is distinguished from typed data using a software data processing application. The software is configured to identify scanned data based on characteristics of the scanned data. Processing functions are next performed on the detected data according to the particular application being used.

International Classification:

H04N 5/355
H04N 5/378
H04N 5/3745
G01J 3/50

Abstract:

A photodetector arrangement having adjustable output, comprises a photodetector having an array of pixels wherein each pixel. The pixels are arranged to convert electromagnetic radiation into an analog detection data signal, respectively. A readout circuit is coupled to the photodetector and comprises a receiving component and a combining component. The receiving component is arranged to read out detection data signals, to select at least one detection data signal depending on a control signal and to adjust gain and polarity of the selected detection data signal. The combining component is arranged to combine the detection data signals into one or more output signals to be provided at one or more output terminals. A control unit is coupled to the readout circuit via a control terminal and is arranged to provide the control signal at the readout circuit depending on a set of instructions.

International Classification:

G01J 3/02
G01J 3/51
G01J 3/46

Abstract:

A colour sensor arrangement comprises a colour sensor arranged to generate at least a first channel signal being indicative of a colour of light incident on the colour sensor. A processing unit is connected to the colour sensor and arranged to generate a tuple of colour signals by processing the at least first channel signal. A memory is connected to the processing unit and a control unit is connected to the processing unit and to the memory. Furthermore, the control unit is arranged to receive calibration data relating the tuple of colour signals to a calibrated tuple of colour signals and arranged to store said calibration data (M) by means of the memory. An interface is connected to the processing unit and comprises an interface terminal.
