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.

Abstract: The present invention assures the integrity of state information retained by a Radio Frequency Transponder during a loss of power. During the regular operation of the Transponder power is provided to a voltage-storing device powering an information retention mechanism of the Transponder. After the loss and reestablishing of power to the Transponder but before the Transponder is restarted, the voltage-storing device is checked to determine whether sufficient power is present in the information retention mechanism to retain information without corruption. If sufficient power is present, a signal to indicate that fact is communicated to the Transponder and the stored information is restored. The Transponder is then restarted.

Abstract: An optical assembly includes a first tubular member having a pitched bearing surface proximate one end; a second tubular member having a pitched bearing surface proximate one end; a coupling tubular member fixedly coupled to the second tubular member and rotatably and slideably coupled to the first tubular member; and an optical element received in at least one of the first, the second or the coupling tubular members. At least a portion of the pitched bearing surface of the first tubular member is in engaging contact with at least a portion of the pitched bearing surface of the second tubular member. Rotating the first tubular member with respect to the second tubular member smoothly varies a distance between the first and second tubular members and allows a large, smooth adjustment with little effort. Rotation in a single direction returns the distances to an initial starting point.

Abstract: A proxy RFID read/write unit is used in conjunction with a non-RFID enabled network printer to add a capability to a local area network (LAN) to encode RFID transponders that are either embedded in print media or separate from the print media. The proxy RFID read/write unit is adapted perform the following functions: (a) detecting a message packet directed to the network printer containing a command to print a bar code label; (b) recovering information from at least one data field of the message packet; and (c) writing the information to an RFID transponder. If the network printer is adapted to print onto label media containing embedded RFID transponders, and the RFID interrogator is oriented with respect to the network printer so that a mouth of the printer is disposed within the interrogating range, the information can be written to an RFID transponder embedded in a corresponding print label of the label media.

Abstract: A method for reading optical indicia involving the application of different symmetrical transforms to each of a plurality of images of an optical indicia. Characteristic features are identified in the transformed frequency domain representation of each transformed image, the characteristic features corresponding to repetitive features found in the original non-transformed representation of each image. Modified images are created by subjecting the frequency-domain representation of each image to an inverse transformation. The modified images can be combined to create an improved representation of the optical indicia being read. Thus, the depth of field and efficiency of an optical indicia reader can be enhanced.

Abstract: Buildings such as residences and commercial locations may have a data marker such as a barcode and/or RF device. A data marker may store/carry data indicative of an address. This allows verification of a physical address of a location and/or a name of an owner, business(es), residents, and/or employees at that location. A service provider may utilize the data marker during the provision of services. For example, when a package is to be delivered, the data marker may be scanned/interrogated for address verification and then the item may be delivered. This speeds up the tracking and delivery of goods and services. It also reduces or eliminates human error during delivery as every residence and business has an address.

Abstract: A process for detection of straight-line segments in a stream of digital data that are representative of an image (m, n) in which the contour points of said image each defined by the modulus and the orientation ? of their gradient in relation to a horizontal axis are identified. The stream of digital data is stored in the form of two successive lines, each of n points P(i, j), for each of the lines the n points of said line are extracted successively, and for each point Pc(i, j) extracted, the so-called current point, the three points having inferior coordinates Pa(i?l, j?l), Pb(i, j?l), Pd(i?l, j) directly neighbouring said current point are extracted, successively the value of the orientation of the current point Pc is compared with that of the neighbouring points Pa, Pb and Pd. The values of the orientations of the points Pb and Pd are compared, the result of a comparison is validated if the points are contour points and if the values of their orientation are close.

Abstract: A media processing apparatus includes a self-calibrating encoding assembly that send read/write inquires to determine appropriate power levels for encoding encodable objects. The apparatus includes a control subsystem that tracks the power levels of the encoding assembly and the corresponding positions of media carrying the encodable objects. The controller then determines an encoding window and an encoding power level at which the encoding assembly encodes an encodable object in the encoding power window without unwanted communication to encodable objects outside of the window.

Abstract: A laser scanner with a 2D resonant electrostatic micro-mirror has improved aiming visibility, reduced tilt dependence and improved read range. The laser scanner has a field of view that defines a 3D volume and utilizes a laser beam in a light path that is thin relative to the 3D volume. Physical pixel height is enlarged to aid optical imaging plane alignment. A selective filter centered on the lighting wavelength is placed in the image path. The height of the pixel may be artificially induced to be m*w, where m is the lens magnification and w is the light thickness. Diagonal progressive scanning is used to maximize the frequency values so shock resistance of the mirror is increased.
