    摘要： A low product stock display system for detecting at least one of fully stocked, partially stocked, and empty (no stock) shelf has been described. The presence/absence of stock can be detected by conductive contact sensors, inductance sensors, weight sensors, optical sensors, and, in the preferred embodiment, with an RF transmission line. The data from a sensor is wirelessly relayed to an external server for processing across a plurality of facilities, and can provide alerts to personnel or systems responsible for reordering or restocking the particular shelf or display at the facility.

    摘要： A system for conserving battery life in a battery operated device such as a tire tag where there are several modes of operation. The typical mode is the deep sleep mode where the tag is generally inactive (no clock is running; however, an RC watchdog timer is running, which uses very little power). The tag spends most of its time in this low power mode. The tag periodically partially awakens to a lucid sleep mode (when the watchdog timer times out), initiates a low-speed clock, determines if it is time to enter a search mode by examining a search mode counter and, if it is not time, adjusts the search mode counter (e.g., decrements the counter by one), and returns to the deep sleep mode. The tag sleeps in the deep sleep mode most of its life in an effort to conserve battery power. During the deep sleep mode, because the clock oscillators are OFF, a deep sleep counter is adjusted (incremented or decremented) periodically (e.g., about every 18 ms) by an internal R/C oscillator. The internal watchdog timer (WDT) monitors the deep sleep counter and when the deep sleep counter, for example, contains a NULL value (all zeroes) the WDT wakes up the microcontroller (i.e., the WDT initiates the low-speed clock so that the tag cannot enter the lucid sleep mode). The tire tag delivers data at a slower or faster rate to achieve the important advantage of extending battery life. Also to extend battery life two oscillators are desirable because they allow two clock speeds. Having two clocks allows a designer to minimize use of the high-speed clock, thus conserving battery power.

    摘要： Systems and methods are provided for monitoring a plurality of RFID tags. A system includes a plurality of serially connected transmitters along a transmit path, where each of the serially connected transmitters are configured to relay a received transmitter selection signal when the transmitter selection signal identifies a selected transmitter as being further along the transmit path than the serially connected transmitter and transmit an identification impulse using a transmit antenna when the transmitter selection signal identifies the serially connected transmitter as being the selected transmitter. A system further includes a control unit responsive to a plurality of transmit paths, the control unit being configured to send the transmitter selection signal along a selected transmit path, where the transmitter selection signal identifies one of the plurality of serially connected transmitters along the selected transmit path as the selected transmitter for transmitting the identification impulse.
