    摘要: In accordance with the teachings described herein, systems and methods are provided for approximating the location of an RFID tag in an RFID system. The RFID system may include a plurality of receivers that receive RF signals from the RFID tag. Tag read count data for two or more of the plurality of receivers may be used to identify a number of times that each of the two or more receivers has received an RF signal from the RFID tag over a period of time. Signal strength data may be used to identify the strength of the RF signals received from the RFID tag. A combination metric for each of the two or more receivers may be determined as a function of the tag read count data and the signal strength data. The combination metrics may be compared to identify one of the receivers that is closest in proximity to the RFID tag.

    摘要: A contact-based system for inexpensively monitoring the presence, location, and timing of various advertising and merchandising materials at a variety of retail facilities has been disclosed. This includes sign holders, display holders, stocking section identifiers, and the like that contain a plurality of contact point sensors that match or mate with contacts positioned on the material to be monitored. Identifying contacts are placed on the material to be monitored at a factory such that when they are inserted into a pre-specified location at a facility, contact is made. The contact data is then decoded data and relayed wirelessly to a device at the facility that in turn relays the data to a remote server to determine if the merchandising materials have been positioned in that facility and at a plurality of facilities at the right place and at the right time.
