摘要:
A sales incentive system utilizing a portable handheld optical code reader for use by a consumer for scanning bar code symbols corresponding to product items to be purchased, including a memory for storing symbol data of items scanned by the reader a computer receives the stored data associated with the scanned items from the memory of the reader, and selectively generates coupon information based upon sales offers for specific products currently available based upon an analysis of the stored data by the computer. A printer may be coupled to the computer for printing at the consumer's location a set of coupons corresponding to the coupon information transferred from the computer to the consumer's location.
摘要:
In an electro-optical system for reading ultraviolet (UV) light-responsive indicia illuminated by a UV light beam having a wavelength shorter than visible light, safety techniques are described for reducing exposure to the UV light beam to within safe limits.

Management data is uploaded and downloaded in the field to data capture systems, such as electro-optical readers, RFID readers, and imagers, either before, after, or during data capture in a manner transparent to the system without disturbing the data capture.

A technique for on-demand power wake up for digital signage includes providing 400 a detector operable to detect an envelope of a digital signal, receiving 402 an extended length packet by the detector, wherein the packet consists of a same, repeated data symbol, detecting 404 the extended length packet in the detector to provide an output signal, comparing 406 the output signal against a reference threshold, and providing 410 a wake up signal if the output signal exceeds the reference threshold. This can then be followed by receiving 416 information to display on the sign.
摘要:
An imaging system (20) for an imaging-base bar code reader (10) having a housing (11) and a window (17). The imaging system (20) includes a dual camera assembly (22) having a first camera assembly (24) and a second camera assembly (26) mounted within the housing (11) to image a target object (14a, 14b). The first camera assembly (24) includes a first field of view (FOV1) and the second camera assembly (26) including a second field of view (FOV2). The imaging system (20) further includes a fold mirror (36, 37) and positioned within the bar code reader housing (11) to intersect and direct the field of view of at least one of the first and second camera assemblies (24, 26) such that the first and second fields of view (FOV1, FOV2) pass through the exit window (17) and are substantially congruent exterior of the housing (11).
摘要:
An image of a target in a far-field range of working distances relative to an image capture system is focused at a first group of sensors in a common, two-dimensional, array of sensors, and an image of an optical code in a near-field range of working distances relative to the system is focused at a second group of sensors in the array. The same array is shared in a portable apparatus capable of capturing target images and optical code images without moving any optical components.

摘要:
A scan engine (52, 66) for imaging a target object (30) comprises a photosensitive circuitry (58, 76) located within the scan engine (52, 66) for capturing an image reflected from a target object (30) to the scan engine (52, 66). A communication interface (60, 78) is disposed within the scan engine (52, 66) and coupled to the photosensitive circuitry (58, 76) for communicating an undecoded signal (62, 80) to a remote device (14) over a digital serial interface.
