摘要： A method of reading a plurality of bar codes during a scanning motion across a bar code scanner which enhances scanner operation. The method includes the steps of obtaining data from a detector in the bar code scanner, determining position information associated with the data, distinguishing data associated with each bar code using the position information, and assembling the bar codes from the data.

摘要： A system for collaborative bar code error detection and correction comprises a network of individual scanning entities for scanning bar-coded labels. Each individual scanning entity includes a scanning system having a decoder for decoding scanned bar code information and a printhead defect identifier for identifying printhead defects from scanned bar code information that cannot be decoded and for constructing printhead defect models for use in correcting future bar code scans. A log is provided at each individual scanning entity for storing locally constructed printhead defect models and printhead defect models that have been constructed at other scanning entities in the network. Each individual scanning entity has an error corrector for correcting erroneous scanned bar code information using the locally stored printhead defect models. Further, each scanning entity includes a network connection for broadcasting locally constructed printhead defect models to the network and for receiving broadcasts of printhead defect models constructed at other scanning entities in the network.

摘要： A method and circuit for controlling the contrast of a liquid crystal display (LCD). The circuit includes a switching regulator circuit which generates a negative voltage at the output thereof, with the switching regulator circuit having a feedback node therein and also having a voltage regulator with a control input therein. An injected current coupled to the feedback node and the control input to the voltage regulator is used to provide a changed negative voltage at the output of the regulator circuit. Control values stored in the memory of a controller are used to select the injected current. The changed negative voltage at the output of the regulator circuit is used to control the contrast of the LCD.

摘要： Disclosed is a Software Sanity Monitor for automatically detecting and remedying software lock-up conditions without user intervention. Users often refer to these conditions as “hangs” or “forever loops”. Although the Software Sanity Monitor uses the operating software's information, it is designed to execute independent of the operating system software; thereby, eliminating reliance on a “sane” operating system. If a “hang” condition is detected, the Software Sanity Monitor will automatically restart the system after logging the failure and, optionally, notify the user or host system.

摘要： A method and apparatus are provided for simulating a bar code. The bar code simulator includes a code emitter for generating a coded light beam which varies sequentially in intensity to correspond with bar code bars and spaces, and varies sequentially in duration to correspond with varying width of the bars and spaces. The flashing light beam so produced corresponds with the flashing back scattered light which would otherwise be produced by sweeping a scan beam across a bar code label. The independently produced coded beam simulates back scattered light which is identically detected by a scanner and decoded thereby.

摘要： The present invention provides a system for correcting improperly printed or otherwise defective bar codes. The system scans a bar code and determines whether the scanned bar code data is correct. If the scanned bar code data is incorrect, the system uses the incorrect scanned bar code data to create a scan-based printhead model. The correct data is entered manually, and the manually entered data is used to construct an active printhead model. The scan-based and active printhead models are then compared in order to identify printhead defects, which are stored to correct future bar code scans.
