Disclosed are barcode scanners and methods for scanning a barcode. The barcode scanners and methods for scanning a barcode may include receiving a raw image from a scanner. Channel information may be extracted from each pixel of the raw image. A composite image may be created using the channel information from each pixel of the raw image. Finally, product information may be extracted from the composite image.

Barcode scanner optimization

Various embodiments herein each include at least one of systems, devices, methods, and software for overhead camera synchronization, such as with regard to a camera positioned above a POS terminal or other kiosk terminal type. One embodiment in the form of a method includes adjusting at least one of an exposure setting of an imaging device and lighting within a field of view of the imaging device to affect an exposure within an image captured by the imaging device. This method further includes capturing an image with the imaging device with the at least one of the exposure setting of the imaging device and the lighting within the field of view of the imaging device to achieve a desired exposure within the captured image.

Overhead camera synchronization

Systems and techniques for generating data showing a signal environment experienced by a radio frequency identification (RFID) communication device. A transceiver within the communication device sweeps through a frequency range of interest in order to receive signals within the frequency range. Depending on the nature of the signals of interest, the signals detected may be reflected signals generated in response to a carrier signal produced by the communication device, or active signals produced by active sources. Baseband analysis is performed in order to detect and identify reflective signals, and spectrum analysis is performed in order to detect and identify active signal sources.

Methods and apparatus for analyzing signal conditions affecting operation of an RFID communication device

A method, apparatus, and system for periodically measuring the level of ambient noise found on a radio frequency channel used by a radio frequency identification interrogator to read radio frequency identification tags. The ambient noise is measured after the radio frequency identification interrogator has transmitted a signal. The measured level of ambient noise is then used to dynamically adjust a threshold value used to predict collisions on the channel.

Method and system for tuning an RFID interrogator

A system and method of reducing noise in an electronic shelf label system which shifts operation of the receiver away from noise frequencies. The system includes a controller for receiving signal levels and noise levels at different frequencies from a homodyne receiver, and for shifting operation of the receiver away from noise frequencies.

System and method of reducing noise in an electronic shelf label system

A communication device and method for electronic price label (EPL) systems which use EPL components. The device includes a microcontroller, a first EPL circuit enabled by the microcontroller which sends a first signal to an EPL computer in response to a first polling signal from the EPL computer indicating that data from the microcontroller is ready for transmission, a number of second EPL circuits which store the data from the microcontroller and which send the data to the EPL computer in response to a second polling signal from the EPL computer, a third EPL circuit which receives a second signal from the EPL computer acknowledging receipt by the EPL computer of the data, and which signals the microcontroller of the receipt of the data, a keypad coupled to the microcontroller for recording the data from an operator, and a display for displaying the data as it is recorded and for displaying an indication of the receipt of the data.

Communication device and method for electronic price label systems

A system and method of reporting a status of another system through an electronic price label (EPL). The system includes the EPL and a computer coupled to the EPL which monitors the status of the second system and causes the EPL to display a status message indicating the status of the second system. The second system may include a POS system, credit authorization system, or any other in-store system.

System and method of reporting a status of another system through an electronic price label system

An electronic price label (EPL) which includes a plurality of separately-addressable displays. The EPL includes a housing, a first display identified by a first unique identification number, a second display within the housing identified by a second unique identification number, and circuitry within the housing for controlling each of the first and second displays in response to messages received by the circuitry which are addressed to the first and second displays using the first and second unique identification numbers.

A remote control device and method for electronic price label (EPL) systems which includes circuitry from EPLs. The remote control device includes a first EPL circuit, a second EPL circuit, and a control circuit coupled between the first and second EPL circuits for enabling transmission of alternating signals to the EPL computer by the first and second EPL circuits. The EPL computer executes a function in response to the alternating signals.

Remote control device and method for electronic price label systems

An electronic price label (EPL) including a noisemaker to assist in locating the EPL. Besides a noisemaker, the EPL includes processing circuitry which activates the noisemaker upon receipt of a command from a computer. A method for locating an EPL includes the steps of providing a noisemaker within the EPL, and transmitting a first signal to the EPL including a command to activate the noisemaker from a computer. The method may additionally include the steps of providing a plurality of receiving antennae, determining locations of the receiving antennae, transmitting a second message to the EPL by a computer coupled to the receiving antennae, listening for a third message from the EPL in response to the second message by the computer, determining signal strengths of the third message at each of the receiving antennae, and determining an estimate of the location of the EPL from the signal strengths by the computer.
