Abstract: Various embodiments of the present disclosure identify radio frequency identification tag(s) and/or location(s) thereof. Embodiments may perform such identification utilizing any number of antennas configured at various power levels and/or frequency channels, such as by incrementing and/or decrementing the power level of each antenna and measuring a number of tag reads at interval for each antenna. Confidence scores for each antenna may be generated and compared. Some example embodiments initiate an interrogation command associated with a RFID tag, cause activation of a plurality of antennas at a plurality of transmit power levels, identify a count of tag reads associated with each antenna, and determine a tag location associated with the RFID tag based on the count of tag reads for each antenna.

Abstract: A scanner system is operable for gathering graphic data from a scan target. The scanner system has a single illumination source component operable for generating light, for aiming the scanner system with a filtered beam of the generated light directed at the scan target, and for illuminating the scan target with the directed light. The scanner system also has a detector component operable for sensing a reflection from the scan target, the sensed reflection including a portion of the directed light with which the scan target is illuminated, and for detecting information in the sensed reflection, in which the information detected in sensed reflection corresponds to the graphic data gathered from the scan target.

Abstract: Volume dimensioning employs techniques to reduce multipath reflection or return of illumination, and hence distortion. Volume dimensioning for any given target object includes a sequence of one or more illuminations and respective detections of returned illumination. A sequence typically includes illumination with at least one initial spatial illumination pattern and with one or more refined spatial illumination patterns. Refined spatial illumination patterns are generated based on previous illumination in order to reduce distortion. The number of refined spatial illumination patterns in a sequence may be fixed, or may vary based on results of prior illumination(s) in the sequence. Refined spatial illumination patterns may avoid illuminating background areas that contribute to distortion. Sometimes, illumination with the initial spatial illumination pattern may produce sufficiently acceptable results, and refined spatial illumination patterns in the sequence omitted.

Abstract: An apparatus and method are disclosed for creating an integrated access door and switch actuator. The integrated access door and switch actuator are created from a single composite material. The composite material is flexible to allow movement, but is also durable to provide a protective covering. The integrated access door and switch actuator include a hinge, which allows the access door to move to an open and closed position while the switch actuator is stationary in a fixed position.

Abstract: This invention provides an extensible method for performing management operations on known and unknown targets. The extensible method is implemented on a fully extensible system where management software and triggers that cause these management operations to be run are easily extended in the field. The triggers may include information indicating a change in inventory, product state, or an event, and may originate directly from a product or from an information store containing information about installed products. The management software facilitates mining this information, parsing the information through a manifest of the triggers, and selecting functions to determine if a management operation should be executed, and if so, which management operation. Generally, the management software executes the selected management operation.

Abstract: A color symbology, such as a bar code symbology, employs three or more colors to encode elements of one or more integer-widths. A light source or an appropriate filter of a color matched to one color of the symbology produces peaks in a reflectance signal produced from a light sensor, which receives light reflected from the symbol. Another, unmatched, color in the symbology produces valleys in the reflectance profile. A third or intermediate color produces a reflectance signal in a middle portion of the reflectance profile. By identifying the peaks and valleys in the profile, the portions corresponding to the intermediate color, may be found by measuring distances between centers of the peaks and valleys in the reflectance profile. As a result, all elements, of all colors in the symbol, may be decoded using a simple data collection reader, such as a laser scanner, employing only a single color laser.

Abstract: An on-demand subsurface printed label. Indicia is reverse printed on the back of a clear plastic label film. Resulting label is suitable for harsh environments without requiring pre-printing or use of an extra protective outer layer.

Abstract: A multi-layer label/tag is disclosed, which may be utilized either as a label or a tag, depending on the needs of the user. The label/tag includes a printed or printable top face sheet and a number of release layers. The top face sheet is attached to the release layers such that it may be removed as a tag or as a label. Cutting through the multi-layer assembly allows a user to remove the item as a label or a tag, as needed.

Abstract: A method and system for intelligently routing data received from an automatic data collection (“ADC”) device in an ADC device platform based on its type. A data routing mechanism operates on the data-receiving side of an ADC data server. After identifying the characteristics of the input data, the data routing mechanism determines the destination for the data based on the characteristics, then routes the data to the selected destination. For some types of data, the selected destination may be an intermediate destination where the data undergoes additional processing before being transmitted to another location, while for other types of data the selected destination may be the application that ultimately processes the data. For example, the data routing mechanism may receive a set of input data, analyze the data to determine that the data is voice data, and then route the data to a speech recognition module that processes voice data.

Abstract: A new bar code symbology in an exemplary embodiment employs three bars (and spaces) within nine modules, similar to Code 93. Fifty-three data characters are defined, including several special mode characters. By employing these special mode characters, together with certain routines, three symbol characters can represent two 8-bit bytes, or one 16-bit word. As a result, the symbology can efficiently encode 8-bit bytes for use in computer processing, or encode 16-bit character sets such as Unicode. Symbology encodes extended channel interpretation (ECI) numbers, provides multiple numeric compression modes, provides a structured append using a single mode character, as well as other features. Additionally, the symbology includes error correction, with a Special Features Flag character indicating use of error correction in a symbol.

Abstract: An antenna structure including a driven antenna element is formed on a substrate that is folded to provide a closed surface, causing the substrate to be nonplanar and spacing the driven antenna element from a base of the substrate. Adhesives on an outside surface of the substrate permit fastening of the folded substrate to a container or packaging. The substrate may have one or more resilient elbows formed by folding, to bias the antenna element carrying portion of the substrate from the base of the substrate. A modulation circuit may drive the driven antenna element. The flexible substrate may be folded into any of a variety of forms such as a substantially O-shape, a substantially oval shape, a substantially coil shape, a substantially spiral shape, and a substantially S-shape. Additional folds in the substrate may provide surfaces for mounting passive or parasitic antenna elements, such as reflectors and directors, to form a Yagi antenna structure.
