Abstract: A system includes a terminal, a wireless access network, a multimedia core network and a network device, which connects the wireless access network to the multimedia core network, expanded location updating to the registration procedure of the multimedia core network, and performs double registration of the user to the multimedia core network. The terminal performs expanded location updating relaying the registration point identity of the multimedia core network, the user's phone number and the private user identity to the network device in connection with normal location updating signaling. In the double registration performed by the network device, two addresses are registered for the user of the terminal, one of which is associated with the domain name of the terminal in question or a numeric IP address, and the other to a domain name of the network device or a numeric IP address.

Abstract: Systems and methods of determining the volume and dimensions of a three-dimensional object using a dimensioning system are provided. The dimensioning system can include an image sensor, a non-transitory, machine-readable, storage, and a processor. The dimensioning system can select and fit a three-dimensional packaging wireframe model about each three-dimensional object located within a first point of view of the image sensor. Calibration is performed to calibrate between image sensors of the dimensioning system and those of the imaging system. Calibration may occur pre-run time, in a calibration mode or period. Calibration may occur during a routine. Calibration may be automatically triggered on detection of a coupling between the dimensioning and the imaging systems.

Abstract: A total number of transponders in an interrogation field is estimated or determined based on demodulated baseband direct and quadrature components from a plurality of collided responses from multiple transponders, including collided responses from which information encoded therein cannot be recovered, and would conventionally be discarded. A query or Q value may be set without an a priori knowledge of the actual number or even approximate number of transponders in the field of the interrogator or reader. Such may allow transponders to be quickly and efficiently singulated, for example in a single pass, and information read from and/or written to singulated transponders.

Abstract: A 2D bar code reader with improved motion tolerance is presented. The 2D bar code reader includes a lens configuration that enhances chromatic aberration to separate the focal planes on which bar code images from two different color components of a light will be focused. An imager interprets one of the focal planes as the image and the other one as noise to be ignored. In addition, the increased depth of field generated by the chromatic aberration allows for a larger aperture stop setting and quicker shutter speed, thereby improving motion tolerance.

Abstract: A content applicator receives a continuous medium and applies content to segments of the continuous medium. The content applicator includes a sensor array, a controller subsystem, and a print station. The sensor array scans the continuous medium as the continuous medium moves along a medium transport pathway. The controller subsystem receives scan information from the sensor array and uses the scan information to establish and maintain registration between the continuous medium and the print station.

Abstract: The invention relates to a method for operating an RFID network consisting of a number of read-write stations (1, 2, 3, 11, N0-N17), for which a reader service signal (9, 105) is modulated onto a read-write signal that is required to process a number of electronic labels (6). According to the invention, the following steps are carried out: at least one read-write station (1 2, 3, 11, N0-N17) is entrusted with the function of a master (100) that has stored a network structure (110) comprising structure data and a co-ordination plan containing co-ordination data; the master or masters transmit(s) (100) at least corresponding data for an organized synchronous network operation to the read-write stations (1, 2, 3, 11, N0-N17) periodically and/or on demand, so that the read-write stations (1, 2, 3, 11, N0-N17) do not interfere with one another during the read-write operation.

Abstract: A printer is described herein that is equipped to internally remove the backings off of self-adhesive label paper, exposing an adhesive layer when ejected from the printer. A user desiring to print some sort of indicia on the self-adhesive paper need only initiate printing, and a label with exposed adhesive is ejected from the printer. A print side of the paper is split from a backing inside the printer pulling preceding print sides and backings at certain tensions, thereby creating a particularly effective separation angle. A ribbon break shaft and one or more rollers create the correct tension in the print sides, while a platen roller and cantilever leaf spring create the correct tension in the backings. In some embodiments, the optimal separation angle lies between 19 and 25 degrees.

The carriage includes a first notch to receive a rod of the linear actuator and a second notch to receive the guide. The carriage remains in direct and continuous contact with the linear actuator and the guide at the first notch and second notch, respectively, when the carriage moves linearly back and forth along a travel axis.

Abstract: System, method, article for determining registration and/or skew errors in a print medium with respect to a printing element includes a print medium including a two-dimensional pattern including a grid within a geometric shape. The grid has a plurality of vertical and horizontal lines, the intersection of each forming a cross-hair defining an X-Y positional data point; the collection of data points defining a data set. The geometric shape is in the form of a two-dimensional target having a plurality of concentric rings; an innermost one enclosing at least one of the X-Y positional data points in the data set. The printing element provides a marker onto the print medium. The positional location of the marker with respect to the one of the at least one enclosed X-Y positional data point defines a directional displacement vector for correcting registration and/or skew error between the print medium and the printing element.

A detector is used to capture images at different positions relative to the optical system. Transforms and blur spread parameters are calculated for the images for use in determining a position to which the detector should be moved to autofocus the system.

Abstract: Data carriers (such as RFID tags) are formed into clusters of data carriers. Each cluster has at least one bridge data carrier that can communicate with a bridge data carrier of another cluster, thereby allowing data carriers in each cluster to communicate directly or indirectly with each other using a stochastic communication protocol method. Direct tag-to-tag communication capability is provided between data carriers in each cluster and/or between clusters. The data carriers can backscatter and modulate a carrier wave from a source, thereby using the backscattered and modulated carrier wave to convey data to each other.

The enhanced level of security for the selected shipping items is based at least on the information gathered at the tracking stations. The enhanced security is provided in such a way that personnel of the shipping and delivery system cannot physically discern whether or not a shipping item is being shipped with enhanced security.
