An improper barcode can thus possibly be identified and further investigation initiated. | 01-03-2013 |
20120325909 | IMAGING READER WITH NON-UNIFORM MAGNIFICATION WITHIN A FIELD OF VIEW - An imaging lens assembly captures return light through a window of a vertical slot scanner from a target located in a range of working distances along an optical axis away from the window, and projects the captured return light onto an array of a solid-state imager. The imaging lens assembly is optically modified for non-uniform magnification within, and for increasing resolution at an outer peripheral region of, a field of view of the array, in an imaging plane generally perpendicular to the optical axis. The magnification is at least partly increased in the imaging plane with increasing radial distance away from the optical axis, to enable reading of the target when tilted relative to the optical axis and located at the outer peripheral region of the field of view. | 12-27-2012 |

Extended use times or smaller form factors can be achieved for devices employing dynamic battery capacity allocation. By determining factors that can include the type of memory, the usage of the memory, and/or the user's preference to continue to use a device rather than retain data in a volatile memory for a period of time before supplying alternative power, the device can be available for use for longer periods of time on a battery or a smaller battery can be used to achieve similar use time. | 12-20-2012 |
20120317267 | PRESENCE-BASED SITE ASSIGNMENT OF A DEVICE - A system and method for presence-based site assignment of a device includes a step of detecting a presence of the device by a network-managed device having a known logical location, wherein the logical location of the device is not known. A next step includes reporting the presence of the detected device to a network manager by the network-managed device. A next step includes assigning the detected device to the same logical location as the first network-managed device by the network manager. Subsequently, a next step includes a second network-managed device detecting the presence of the device and then associating to the logical location of the device. As a result the logical location of devices is inferred by the co-presence of other device having a known logical location. | 12-13-2012 |
20120314634 | CLIENT BRIDGE BETWEEN WIRED AND WIRELESS COMMUNICATION NETWORKS - A method and client bridge for bridging clients between a wired and wireless communication network includes a radio transceiver with a register and a controller for indicating to the wireless network that all wired client devices of the wired network are in Power Save Polling (PSP) mode, selecting the next wired client to be indicated as being in Continuously Awake Mode (CAM) mode, storing a Media Access Control (MAC) address of that selected client in the register, indicating to the wireless network that the selected client is in CAM mode, receiving any packets from the wireless network, which are acknowledged using the register, indicating to the wireless network that the selected client is back in PSP mode, and repeating these operations until all wired client communications are serviced. | 12-13-2012 |
20120297230 | SYSTEM AND METHOD FOR CHARGING A BATTERY - Described is a system and method for charging a battery. The system includes a processor powered by a battery; and a controller determining a remaining battery charge of the battery. The controller sets a first charge current to recharge the battery when the remaining battery charge is insufficient to operate the processor. The controller wakes the processor when the battery has been recharged so that the remaining battery capacity is sufficient to operate the processor. The processor negotiates for a second charge current to recharge the battery. The controller sets the second charge current when the processor successfully negotiated. | 11-22-2012 |
20120287332 | IMAGING READER WITH INDEPENDENTLY CONTROLLED ILLUMINATION RATE - An imaging module for electro-optically imaging a target, includes an energizable illuminating light source for illuminating the target with illumination light for return from the target, an energizable solid-state imager for capturing return light from the target, and a controller for energizing the imager during an exposure time period to capture the return light at a frame rate, for deenergizing the imager during a non-exposed time period, and for energizing the illuminating light source not only during the exposure time period, but also during the non-exposed time period, to produce a plurality of illumination light pulses at an illumination rate that enables the human eye to perceive the illumination light pulses as substantially continuous. The illumination rate of one or more of the illumination light pulses produced during the non-exposed time period is substantially independent and decoupled from the frame rate. | 11-15-2012 |
20120273572 | POINT-OF-TRANSACTION WORKSTATION FOR AND METHOD OF IMAGING INDICIA OVER FULL COVERAGE SCAN ZONE OCCUPIED BY UNSKEWED SUBFIELDS OF VIEW - A bi-optical, dual window, point-of-transaction workstation images indicia associated with multi-sided products over a full coverage scan zone by splitting each field of view of only two imagers into three subfields that pass through each window and fill the scan zone and minimize dead areas therein. Twisting of the subfields relative to the windows is minimized so that the subfields fit fully with minimal clipping through each window. Splitting of each field of view is remotely performed well away from each imager. The imagers have lens assemblies of substantially the same optical power and are spaced from their respective windows by substantially the same distance. | 11-01-2012 |
