  • Publication number: 20140217166
    Abstract: Methods and apparatus for modifying the feature set of data collection devices are disclosed. Requests are receiving at a computer system different from the data collection device for a new configuration of the data collection device, the request including an identifier for the data collection device, identification of one or more features, and for each identified feature, an indication to modify the operation of a feature. The identifier may comprise an identifier that is unique for a particular data collection device or an indication of a group of devices. e.g. a model number. Prior to authorizing the new configuration, a determination may be made as to whether the identified data collection device(s) are suitable for the new configuration by consulting a configuration database. To implement the new configuration, an encoded authorization file is generated based on the requested configuration and the identifier of the data collection device(s).

  • Patent number: 8794526
    Abstract: There is described a decodable indicia reading terminal which in one embodiment can capture and process a certain (e.g., a first) and a subsequent (e.g., a second) frame of image data, wherein the certain and the subsequent frames have different imaging attributes. In one embodiment the attributes between certain and subsequent frames are differentiated in that the certain frame represents light incident on pixels of a first image sensor and the subsequent frame of image data represents light incident on pixels of a second image sensor spaced apart from the first image sensor. Additionally, or in the alternative, the attributes between certain and subsequent frames can be differentiated in that the first frame represents light incident on an image sensor under a first illumination profile and the subsequent frame represents light incident on pixels of an image sensor under a second illumination profile.

The terminal can comprise program instructions to direct an RFID reading device of the terminal to perform a number of reads of the one or more candidate RFID tags in response to determining that an object is present in the line-of-sight, to calculate an accumulated RSSI of each of the one or more candidate RFID tags, and to determine the target RFID tag from a highest accumulated RSSI. In one embodiment, the unique data can be an EPC. There is also provided a terminal for use in converting an EPC into a decoded bar code. The terminal can comprise program instructions to transmit the decoded bar code to a computer such as an electronic cash register.

  • Publication number: 20140204257
    Abstract: The invention features an image reader and a corresponding method for capturing a sharp distortion free image of a target, such as a one or two-dimensional bar code. In one embodiment, the image reader comprises a two-dimensional CMOS based image sensor array, a timing module, an illumination module, and a control module. The time during which the target is illuminated is referred to as the illumination period. The capture of the image by the image sensor array is driven by the timing module that, in one embodiment, is able to simultaneously expose substantially all of the pixels in the array. The time during which the pixels are collectively activated to photo-convert incident light into charge defines the exposure period for the sensor array. In one embodiment, at least a portion of the exposure period occurs during the illumination period.
