Disclosed are embodiments of in-situ display monitoring and calibration systems and methods. An image acquisition system captures images of the viewing plane of the display. Captured images may then be processed to characterize various visual performance characteristics of the display. When not in use capturing images of the display, the image acquisition system can be stored in a manner that protects it from environmental hazards such as dust, dirt, precipitation, direct sunlight, etc. A calibration image in which a plurality of light emitting elements is set to a particular color and intensity may be displayed, an image then captured, and then a difference between what was expected and what was captured may be developed for each light emitting element. Differences between captured images and expected images may be used to create a calibration data set which then may be used to adjust the display of further images upon the display.

In-situ display monitoring and calibration system and methods

A Point-Of-Sale (POS) device detects vibrations produced from equipment in its operational environment. The vibrations are identified and one or more filters produced to remove the vibrations when the POS device is used to improve the accuracy of the POS device.

Disclosed are embodiments of photo-luminescent display systems and photo-luminescent visual elements creating eye-catching displays of visual advertising or marketing messages that are very effective at generating interest, engagement, and loyalty in the viewing public. Photo-luminescent pigment containing visual elements are illuminated by one or more remotely located emitters at a first wavelength that is outside the human visual spectrum. In response, the visual elements then radiate at one or more wavelengths within the human visual spectrum. Additional features control unwanted reflections and unwanted transmission of radiation at the first wavelength. Additional features control the uniformity of radiation of one or more wavelengths within the human visual spectrum.

Photo-luminescent visual elements, systems and methods

An image from a window of a scanner is taken and analyzed to determine whether the image is relevant to dirt or debris on the window. When the image is relevant to dirt or debris, the size and amount of the dirt or debris is compared to a threshold and when the threshold is exceeded an alert is raised to have the window cleaned of the dirt or debris.

Photo-luminescent display system and methods

An optical code scanner is presented that includes an improved user interface and an improved external computer interface. The user interface includes illumination devices that illuminate an air gap between the edges of a weigh plate and the top surface of the optical code scanner. The illumination devices provide guidance to the operator that allows the operator to optimize scanning performance. The external computer interface exposes controls that allow an external computer to determine what information is displayed to an operator.

User interface for an optical code scanner

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.

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 &ldquo;hangs&rdquo; or &ldquo;forever loops&rdquo;. 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 &ldquo;sane&rdquo; operating system. If a &ldquo;hang&rdquo; condition is detected, the Software Sanity Monitor will automatically restart the system after logging the failure and, optionally, notify the user or host system.
