    • 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.

    • 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.

    • 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.
    • 一种用于在诸如轮胎标签的电池操作装置中节省电池寿命的系统,其中存在若干操作模式。 典型的模式是深度睡眠模式,其中标签通常是无效的(没有时钟运行;但是,RC看门狗定时器运行,使用的功率很小)。 该标签大部分时间在此低功耗模式下使用。 标签周期性部分唤醒到清醒睡眠模式(当看门狗定时器超时时),启动低速时钟,通过检查搜索模式计数器确定是否进入搜索模式的时间,如果不是时间, 调整搜索模式计数器(例如,将计数器递减1),并返回到深度睡眠模式。 标签睡眠深睡眠模式大部分时间是为了节省电池电量。 在深睡眠模式期间,由于时钟振荡器为OFF,所以通过内部R / C振荡器周期性地(例如大约每18ms)调整(递增或递减)深度睡眠计数器。 内部看门狗定时器(WDT)监视深度睡眠计数器,当深度睡眠计数器例如包含一个空值(全部为零)时,WDT唤醒微控制器(即,WDT启动低速时钟, 标签无法进入清醒模式)。 轮胎标签以较慢或更快的速率传送数据,以实现延长电池寿命的重要优点。 另外为了延长电池寿命,两个振荡器是可取的,因为它们允许两个时钟速度。 有两个时钟允许设计人员最大限度地减少使用高速时钟,从而节省电池电量。
