    摘要： A distributed antenna array with a centralized data hub for determining the presence and location of RF tags has been disclosed. This antenna array centralizes electronics and distributes the RF to zones in a facility to greatly reduce the expense of recurring components for monitoring RF tags. A single BRT/hub with multiple antennas attached to transmit and receive ports is used to cover an entire facility. Large facilities are covered by a small number of the BRT/hub combinations. The BRT/hub has transmit antennas coupled thereto, preferably by co-axial cable, that transmit signals to a portion or all of the RF tags and all or a portion of them modulate and reflect the RF signal to a particular receiving antenna. The receiving antenna then returns the RF signal with tag data to the BRT/hub, preferably by co-axial cable. Also disclosed is an RF backscatter tag that cleanly switches a resonant aperture antenna on and off, thereby greatly increasing the mark-to-space ratio of the backscatter data. This enables tags to be detected by the BRT at much greater distances.

    摘要： An in-line directional radio-frequency (“RF”) power meter for measuring power and other parameters in a transmission line. The meter simultaneously measures complex voltage-waves traveling in the forward and reverse directions of a connected transmission line and processes measured voltages to compute forward and reverse power, standing wave ratio, and impedance values. The apparatus includes a microprocessor having microcode for digitally computing RF power parameters, and a field programmable gate array (“FPGA”) having microcode for executing complex Fast Fourier Transforms (“FFT”) to calculate voltages and frequencies, a microprocessor with attached firmware to make a series of complex calculations relative to sensed electrical values in the transmission line and to pass certain calculated values to the device to communicate RF power parameters to a user. The configuration of the apparatus allows for measurement of RF power parameters in a relatively economical package.

    摘要： An electronic tire maintenance system is provided for measuring a parameter of a device at a first location. The system includes a sensor for measuring the device parameter and generating a data signal representing the measured parameter. The system also includes a microprocessor coupled to the sensor for activating the sensor on a first periodic basis to measure the device parameter. The microprocessor includes a memory for storing the generated data signal representing the measured parameter. A transmitter and a receiver are coupled to the microprocessor. The microprocessor periodically partially awakens to determine, on a second periodic basis, if a received transmission is a valid interrogation signal and, if so, fully awakens and responds to the valid interrogation signal, via the transmitter, by at least transmitting the last stored measured parameter. In one embodiment, the device is a tire tag mounted inside a tire that measures tire data and transmits that data to a remote source in response to an interrogation request, an alert condition, or automatically on a periodic basis.

    摘要： A pneumatic tire and monitoring device for monitoring an engineering condition of a pneumatic tire includes a pneumatic tire having a sidewall and a plurality of reinforcing cords carried in the sidewall. The monitoring device includes a sensing element that senses at least an engineering condition of a pneumatic tire and transmits the gathered data from the monitoring device to a data gathering device outside of the tire. The transmission occurs through a dipole antenna that is in communication with the sensing element. The dipole antenna is disposed substantially perpendicular to the reinforcing cords in order to maximize the probability of signal propagation through the tire sidewall.

    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.

    摘要翻译： 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。
