Abstract: Systems and techniques for using signal to noise ratio information to enhance bar code scanning accuracy. Noise information affecting bar code scanning operations is stored and a scan signal is monitored. Upon detection of a scan of a bar code, the signal strength of the scan signal is evaluated and signal to noise ratio values are computed. Signal to noise ratio information is used to favor or disfavor candidate decoding results. In addition, signal to noise ratio thresholds are set according to appropriate criteria. Decoding results are evaluated using the signal to noise ratio thresholds and accepted or rejected depending on whether the thresholds are met. In addition, thresholds for recognition of transitions based on peaks may be set based on expected noise affecting the scan signal, and allowed or excluded based on whether a rise from a negative peak, or fall from a positive peak, meets the threshold.

Abstract: A method of indicating the condition of an item comprises illuminating the item to excite one or more photoluminescent markers incorporated within the item. Photoluminescent emission from the markers in response to the excitation is compared to one or more pre-defined photoluminescent signatures indicating different conditions of the item.

Abstract: A method of optimizing data streaming in a peer-to-peer architecture that comprises a plurality of clients in a chain, a peer-to-peer data streaming system having such architecture, and a client terminal for use in that system. Each client monitors its own bandwidth, informs a succeeding client in the chain of that bandwidth, compares its own bandwidth with the bandwidth of a preceding client in the chain and, in response to a difference between the compared bandwidths, reorders its position among the clients in the chain. The chain thus dynamically self-organizes itself to stream data more efficiently and with higher, more reliable throughput, reducing the processing power necessary to stream the data and enabling higher quality to be achieved within the existing internet infrastructure. This also solves the ‘bottle-neck’ problem within the cascaded streaming path by continuously organizing the participating terminals into the most efficient configuration, without interrupting the streamed data.

Abstract: Systems and techniques for retail product transaction processing and security tag deactivation analysis. Upon detection of a security tag deactivation associated with entry of product information into a retail transaction, product information for the product is analyzed to determine whether the security tag deactivation is legitimate or possibly illegitimate. Upon identification of a deactivation as possibly illegitimate, an alert is issued to a retailer employee to investigate the transaction. The product information may be updated according to an entry made by the retailer employee identifying the deactivation as legitimate or illegitimate. Product information for a product may include a deactivation count for a product, with a deactivation being identified as possibly illegitimate if the deactivation count does not meet a predefined threshold, the deactivation count being incremented if a deactivation identified as unexpected is determined to be legitimate.

Abstract: A method of controlling an inkjet mechanism having an inkjet head movable between a capped position and a print position comprises the steps of receiving a first switch signal indicative of the inkjet head moving into the vicinity of one of the positions of the inkjet head as the inkjet head is moving towards the one of the positions of the inkjet head, and moving the inkjet head a learned amount towards the one of the positions of the inkjet head after the first switch signal has been received. The method may further comprise the steps of receiving a second switch signal indicative of the inkjet head moving into the vicinity of the other one of the positions of the inkjet head as the inkjet head is moving towards the other one of the positions of the inkjet head, and moving the inkjet head another learned amount towards the other one of the positions of the inkjet head after the second switch signal has been received. The learned amounts may be substantially the same.

The system includes a good read indicator, a bad read indicator, and control circuitry for notifying an operator of a result of attempting to read a number of product labels, including at least one of a barcode label and a radio frequency identification label on an item. The control circuitry activates a bad read indicator to indicate a single bad read indication if the control circuitry fails to receive item identification information from at least one of the barcode label and the radio frequency identification label, and activates a good read indicator to indicate a single good read indication if the control circuitry receives item identification information from at least one of the barcode label and the radio frequency identification label.

Abstract: Systems and techniques for coordinating data received from radio frequency identification (RFID) tags and additional data input devices. An RFID reader communicates with RFID tags and also receives data from additional input devices that may be correlated with the RFID data. The reader correlates information received from various data sources. Correlation may include validation of RFID data with corresponding data received from other devices. Once data has been received and correlation has been performed, transaction entries are prepared based on the correlated and validated data. Transaction entries may be passed to a data station for processing or logging, or to allow the data station to indicate appropriate actions to be taken. Appropriate software modules used by the reader are changed in response to changes to data input devices or the data station used with the reader.

Abstract: An electronic price label (ESL) system providing a delta update of an ESL's registers. In one aspect, an ESL manager receives and indication that an update to one or more of the registers of the ESL may be necessary. The ESL manager sends a data request to a data reader to provide a data reader image to the ESL manager. The data reader image contains a complete listing of the intended or planned contents of all the ESL's registers, some of which may require an update. The ESL manager reads a copy of an ESL data image from an ESL table which includes the current contents of all the ESL's registers. The ESL manager compares the data reader image with the ESL data image to determine an update data image which includes a subset of only those fields which have different content in the data reader image and the ESL data image.

Abstract: A method of operating Automated Teller Machines, ATMs. An ATM dispenses currency, thereby depleting its supply, and requiring replenishment. Replenishment currently involves humans who (1) measure the currency content of an ATM, (2) compute an amount to be replenished, and (3) report the amounts replenished, when replenishment occurs. These human actions are error-prone. The invention eliminates all three steps. Under the invention, no actual measurement is made of currency content, for replenishment purposes. Instead, the content is estimated. Then, the estimate is used to compute an amount for replenishment. Replenishment occurs, but the fact of replenishment is inferred from signals received from the ATM, and not from a report from a human.
