Abstract:
An RFID tag verifier includes an RF interrogator that transmits a first and second interrogation signal each having a first operational characteristic that differs from the other by a known amount. The RF interrogator receives a first and second return signal corresponding to the respective interrogation signals. A processor determines a response of the RFID tag as defined by a second operational characteristic of the first and second return signals. The verifier can determine the signal strength of the return signal for varying strengths of the interrogation signal. Typically, a flat response is desired Additionally, or alternatively, the verifier can determine the response in terms of signal strength of the response signals for interrogation signals having different frequencies. In some applications frequency selectivity may be desirable. Additionally, or alternatively, the verifier can determine the response in terms of frequency for interrogation signals having varying strengths. A machine-readable symbol verifier can be coupled to, or formed as part of, the RFID verifier. A printer can be coupled to, or formed as part of, the RFID tag verifier.
Abstract:
A method and apparatus for providing a user product information via scanning of a machine readable symbology on a product. A symbology, for example a bar code, is scanned and the data therein passed into a URL which is used to present related product information to a user via the internet. The URL may directly link to the information or be a look up database for further redirection.
Abstract:
One or more reading devices are disposed within a hollow case sized and shaped to be held in a user's hand. A supplemental switch is also disposed in the case and is manually activatable by a user, such as by the user's thumb. Logic disposed in the case is connected to a reading device and the supplemental switch for taking a first action when the switch is activated and taking a second action when it is not. The first and second actions may comprise first and second modes of operation of the reading device. When two or more reading devices are provided, the first and second actions may include reading operations of the first and second devices, respectively. Types of reading devices that may be incorporated into embodiments of the invention include bar code scanners, RF ID interrogators, and smart card scanners.
Abstract:
An optical system, such as a bar code scanner, illuminates an image with a multi-wavelength device. Under a first embodiment, a tunable laser is optically coupled with a prism or other wavelength separation device. As the laser beam wavelength varies, the transmission path through the prism changes, resulting in a scanning of the beam across an image. A photodetector captures light reflected from the image and sends it to a microprocessor for decoding. Under another embodiment, a broad band light source transmits light through a prism, thus shining a “rainbow” on the image. A spectrometer measures reflected light as a function of wavelength and sends the resultant signal to a microprocessor for decoding. Neither embodiment relies on moving parts to scan the image.

A method and apparatus for error correction enhancement for decoding data collection symbols encoding data characters, special function characters, and error correction characters comprising: (i) reading a machine readable symbol; (ii) attempt to decode the symbol; (iii) selecting a group of n successive characters, where n is equal to the number of error correction characters in the symbol; (iv) attempt to solve an error correction equation while treating the group of characters as erasures; and (v) repeatedly selecting groups of successive characters and attempting to solve the error correction equation until the equation is solved or until there are no more groups of n successive characters. The method may further comprise: (vi) selecting a combination of n characters; (vii) attempting to solve the error correction equation while treating the combination of characters as erasures; and (viii) repeatedly selecting combinations of n characters and attempting to solve the error correction equation until the error correction equation solves, or until there are no more combinations of n characters, or until a timeout condition is reached.
Abstract:
A smart label printing system and method for printing smart labels is provided. The smart label printing system enables the expedited programming of the RFID tag component of the smart label so that delays due to the unequal time between printing the exterior of the smart label and encoding the smart label are avoided. The smart label printing system comprises a thermal printing unit to print the exterior of the smart label as well as an RF driver to program the RFID tag embedded inside the smart label. Methods are provided to increase overall throughput speed of the smart label, including prioritizing RFID tag data over exterior printing data in a RAM, compressing RFID tag data sent from a host computer, pre-loading fixed and regularly varying data, and predicting variable unknown data through the use of an artificial intelligence model. In addition, methods for uniquely arranging programming antennas and media pathways which act to speed up overall programming speed are also provided.
