摘要： A scanner such as a bar-code scanner includes a scan-beam generator, a beam reflector having a first magnet, and a beam-sweep mechanism having a second magnet. The beam-sweep mechanism causes the reflector to sweep the scan beam across a target such as a bar-code symbol by exerting a force on the first magnet with the second magnet. In one example, attraction between the magnets holds the reflector steady in a non-sweep position. Conversely, in a sweep position, repulsion between the magnets causes the reflector to oscillate and sweep the scan beam across a target such as a bar-code symbol. Because it does not include a motor for rotating a beam-sweep mirror, the scanner is often smaller and uses less electrical energy than motorized bar-code scanners.

摘要： An apparatus, such as a printer or reader receives a data stream from a memory, such as from an RF or photonic memory, and compares portions of the data stream to a table of data. If a portion of the data matches an entry in the table, a corresponding entry in the table causes the apparatus to be automatically configured. Alternatively, an apparatus receives a data stream to be written, such as in a bar code symbol or tag memory. The apparatus analyzes portions of the data, comparing portions of the data to a reference table. If the apparatus identifies a match, the apparatus adjusts the writing of such data. For example, the printer writes a portion of the incoming data stream to both fields in a bar code symbol and in a portion of the memory in an adjacent RF readable tag.

摘要： A data carrier reader is capable of executing a number of different reading methods. One method performs an inclusive search, identifying all RFID tags having a characteristic data string that appears on a list of characteristic data strings, for example, stored in a buffer. Another method performs and exclusive search, identifying any RFID tags having a characteristic data string that does not appear on the list. In each method, the data carrier reader provides a consistent and intuitive output the user to identify the successful and unsuccessful operations such as locating a desired RFID tag on the list or missing from the list.

摘要： A dual technology printer includes first and second print stations having a polychromatic print engine and a monochromatic print engine, respectively. The print engines are preferably an ink jet print engine and a thermal print engine. A variable length media queue is formed between the two print stations. The queue may be formed by a guide roller that defines a loop of media between the stations and that is movable to adjust the length of the loop and thereby the length of the queue. Preferably, the second print station has a predetermined pixel addressability and a resolution substantially equal to the addressability to produce sharp borders for machine readable symbologies. In a printing operation, the printing of color images at the first print station may be carried out ahead of demand for a particular batch printing operation during which monochromatic images are printed at the second print station.

摘要： A printhead having multiple print lines of conventional design and a printhead control system for using the multiple print lines in a variety of operations. In one embodiment, the printhead control system prints an image by superimposing the printing from multiple print lines. In another embodiment, the image is printed by alternating the energization of one print line so that each print line is used to print only ⅓ of the image lines. As a result, the print lines are allowed a relatively long time to cool, thus allowing the printhead to be operated at a faster speed. In another embodiment, the printing elements of each print line print with a different image density, and images printed by superimposing the printing elements in the print lines with a variety of combinations depending upon the desired magnitude of the image density. In still another embodiment of the printhead control system, the resistance of each printing element is checked and, if found to be unacceptably high, corresponding printing elements of other print lines are used for printing.

摘要： An RF tag for inclusion in a smart label comprises a stiff substrate sized to be received in the smart label, an antenna carried by the substrate and an integrated circuit having a memory circuit carried by the substrate and coupled to the antenna by wire bonding. The substrate may be strain relieved, for example, by forming a pair of generally opposed serpentine edges on the substrate, or forming a plurality of grooves in at least one surface of the substrate. A smart label comprises the RF tag between a face sheet and an adhesive. A release liner may cover the adhesive. A compressably deformable material having a low viscoelastic modulus is received between the first surface of the substrate and the face sheet partially surrounding the circuit structure and wire bonds to hydrostatically protect against damage. A film layer with a blister may envelop the low viscoelastic modulus material.

摘要： A printer for printing on a manually moved print medium. The printer may use thermal or inkjet printing and has user feedback and input. A roller-type position detector enables the printer to be used without a mechanical paper drive mechanism. The printer monitors the print medium as the print medium is propelled through the printer to identify when particular printing fields are aligned to the printhead. The printer then activates the printhead to print image portions in the printing fields. An alternative embodiment of the printer uses a flexible mounting of the printhead. In this embodiment, the paper roll diameter is determined in conjunction with monitoring the rotation of the paper roll to determine the position of the paper without requiring a roller-type position detector.

摘要： An apparatus for use in a thermal printer for printing information onto a paper substrate material is provided. The apparatus enables the thermal printer to compensate for the variable payout force of the paper substrate material. The apparatus comprises a platen in contact with the paper substrate material at a print region of the thermal printer. A motor and a roller mechanically coupled to the motor are used to transport the paper substrate material through the print region. A rotational rate detector comprises a light source, a disk having alternating radially disposed regions of different light conductivity, and a photodetector adjacent to the disk. The disk is at least partially illuminated by light provided by the light source and the photodetector to provide an electrical signal corresponding to detected periodic changes of the light illuminated onto the disk during rotation of the disk in cooperation with the platen. A central processor is adapted to receive the electrical signal and provide a driving signal to the motor. The driving signal compensates for the variable payout force by altering a corresponding transport rate of the paper substrate material in accordance with the detected rotational rate of the disk, an event model stored in a RAM, and/or a harmonic model stored in the RAM.

摘要： A method and apparatus for maximizing print quality in a thermal printer uses a ribbon condition monitor to detect the condition of a multipass thermal ribbon. Data related to the condition of the thermal ribbon at each individual pixel is used to determine a custom energization signal for each thermal print element. In one embodiment, the system utilizes a history memory to track the prior heating history of each thermal print element and an ink memory to track the prior use of each location on the thermal print ribbon corresponding to the thermal print elements. The data from the history memory and the ink memory are combined to form an index to a table memory containing data corresponding to a plurality of energization signal levels for a particular print medium. The data in the table memory provides the custom energization signal for each of the thermal print elements. In an alternative embodiment, a light source and detector are used to determine the thickness of ink remaining on the thermal ribbon. The energization signal is adjusted to compensate for variations in the thickness of the thermal ribbon. In yet another embodiment, data is encoded at one end of a multipass thermal ribbon. The encoded data provides information related to the amount of usage of the thermal ribbon. The energization signal may be boosted for pixels along the edge of a graphic image so as to maximize the contrast of image edges. The system determines whether a particular pixel is located at the edge of a graphic image area and adjusts the energization signal correspondingly.

摘要： A symbology reader uses a linear detector to image a two-dimensional area by scanning the field of view of the linear detector across an image field. In one embodiment, the reader simultaneously decodes data from the linear detector according to two-dimensional techniques and linear and stacked symbology techniques. If the reader identifies a linear or stacked symbology, the two-dimensional processing is interrupted. As the reader scans the field of view of the linear detector across the image field, the scanning mirror simultaneously sweeps a light plane across the image field so that only the imaged region is illuminated, thereby improving the dynamic range of the reader.
