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.

Imaging system

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.

An electronic shelf label with internal information which may be used all locations, including wet locations. The electronic shelf label includes a housing including a substantially transparent portion containing an aperture and an inner surface, a display in the housing for displaying information about an item associated with the electronic shelf label, wherein the display is visible through the aperture, and a layer of material adjacent the inner surface for conveying information about the item.

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.

Fraudulent document detection system and method

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.

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.

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.

Methods and apparatus for reducing the influence of noise in an optical scanning system

A dual-communication electronic shelf label system and method which increase communication bandwidth and minimize competition with other RF systems in a store for bandwidth. The system includes a base station including first wireless downlink communication circuitry and first wireless uplink communication circuitry operating in a different mode than the first wireless downlink communication circuitry, and an electronic shelf label including second wireless downlink communication circuitry for receiving messages from first wireless downlink communication of the base station, and second wireless uplink communication circuitry for sending messages to first wireless uplink communication of the base station.

Dual-communication electronic shelf label system and method

A radio frequency identification (RFID) system with separately located transmitters and receivers which lowers system cost. The system includes a plurality of transmitters for interrogating radio frequency identification tags attached to items on store shelves, a plurality of receivers separately located from the transmitters for receiving response information from the radio frequency identification tags.
