TL;DR: In this article, a hand-supportable Digital Imaging-based Bar Code Symbol Reading Device comprises: an IR-based Object Presence and Range Detection Subsystem, a Multi-Mode Area-type Image Formation and Detection SubSystem having narrow-area and wide area image capture modes of operation; a multi-mode LED-based Illumination Subsystem having narrow area and wide-area illumination modes of operations; an Automatic Light Exposure Measurement and Illumination Control Subsystem; an Image Capturing and Buffering Subsystem.

TL;DR: A wireless communication network for programming and monitoring a plurality of network-managed devices, including electronic-ink based display devices, comprising a network management computer system, a network gateway device, one or more wireless network routers, a majority of network managed devices, and a network coordinator is proposed in this paper.

TL;DR: In this article, a tunnel-type digital imaging-based system capable of generating and projecting coplanar and/or coextensive illumination and imaging planes or zones into a 3D imaging volume within a tunnel structure is presented.

TL;DR: In this article, a checkout system is provided for carrying out a two-factor authentication process where coded products are purchased and theft activity might be pursued, where the system typically includes an identification code reader for reading product identification codes (e.g. UPC bar code symbols or EPC-encoded RFID tags) on products that are passed through the point of sale (POS).

TL;DR: In this paper, an adaptive strobe illumination control process for use in a digital image capture and processing system is described. And the authors present a real-time image analysis based on the results of this analysis, the exposure time (i.e. photonic integration time interval) is automatically adjusted during subsequent image frames (e.g. image acquisition cycles) according to the principles of the present disclosure.
