Abstract: An imaging device comprises a number of light sources, a camera, a processor and a platen. As an object is moved over the platen each of the light sources illuminates the platen sequentially, with the principal axis of illumination of each light source intersecting the plane of the platen at a different place. The camera captures a series of images of the object, each captured image corresponding to the illumination of the platen by a different light source. The processor then generates a composite image from the series of images that compensates for the reflection of light from the platen associated with the principal axis of illumination.

Abstract: An apparatus, method and system to read a bar code or other optical code using a laser device and an image capture device. Using both devices improves the probability that a bar code is read on the first pass while still allowing a high pass by speed. In addition, using both devices improves the probability of reading a damaged or partially obscured bar code.

Abstract: A system for detecting fraudulent documents comprises a barcode reader and a sensor arrangement. The output from the barcode reader and the sensor arrangement are used in conjunction to increase the accuracy of determining if a document is fraudulent.

Abstract: A method of calibrating a scale which enforces exercise requirements. The method includes causing an interface to provide a first indication to place weight on the scale by control circuitry of the scale, receiving weight signals from a load cell by the control circuitry, causing the interface to provide a second indication that exercising has begun and of the level of weight applied by the control circuitry, determining that a minimum recommended calibration weight has been placed on the scale by the control circuitry, and causing an interface to provide a third indication that the minimum recommended calibration weight has been placed on the scale by the control circuitry.

Abstract: A barcode scanner with a tool free tower housing assembly. The barcode scanner includes a base, a tower section coupled to the base, and a tower housing assembly over the tower section including a tower housing and a bezel that are installable and removable without hand tools.

Abstract: Systems and techniques for eliminating or compensating for noise affecting a bar code scanner. A scanner is operated in a learning mode under conditions designed to insure that a scan signal will take on predictable characteristics and noise affecting the scan signal will be easily detectable. During the learning mode, information relating to noise affecting the scan signal and the conditions under which the noise occurs is stored. During normal operation of the scanner, the stored noise information is used in controlling operation of the scanner so as to eliminate or compensate for noise under conditions in which noise has been shown to be susceptible to occur.
