    • Fire resistance can be rated for building structure by providing or having made available, and applying or noting application or presence of fire control agent(s) to or with component part(s) of the structure; providing a fire resistance rating format of a comparative structure; and comparing for a fire resistance classification rating (FRCR). Certification can be effected by providing a security code specific for one-time use in relation to a building structure by a user; entering an FRCR of a building structure rated for fire resistance at a first location and the security code to a communication medium; transmitting by the medium the entered rating and the security code from the first location to a second location; and checking the security code of the user to insure it is authorized and specific to that user; if so, recording the rating supplied by the user; if not, notifying an appropriate monitor.
    • 可以通过提供或提供可用的建筑结构来对建筑结构进行评级,并向施工结构的组成部分或与其结构的部件应用或注意使用或存在防火剂; 提供比较结构的耐火等级格式; 并对耐火等级(FRCR)进行比较。 认证可以通过提供用户对建筑结构的一次性使用特定的安全代码来实现; 在第一位置进入被评为耐火建筑结构的FRCR,并将密码输入通信介质; 由介质将输入的评级和安全码从第一位置传送到第二位置; 并检查用户的安全代码,以确保其被授权并且对该用户具体; 如果是,记录用户提供的评级; 如果没有,通知适当的监视器。

    • A circuit board for wireless communications includes communication circuitry for modulating and/or demodulating a radio frequency (RF) signal and an antenna apparatus for transmitting and receiving the RF signal, the antenna apparatus having selectable antenna elements located near one or more peripheries of the circuit board. A first antenna element produces a first directional radiation pattern; a second antenna element produces a second directional radiation pattern offset from the first radiation pattern. The antenna elements may include one or more reflectors configured to provide gain and broaden the frequency response of the antenna element. A switching network couples one or more of the selectable elements to the communication circuitry and provides impedance matching regardless of which or how many of the antenna elements are selected. Selecting different combinations of antenna elements results in a configurable radiation pattern; alternatively, selecting several elements may result in an omnidirectional radiation pattern.
    • 用于无线通信的电路板包括用于调制和/或解调射频(RF)信号的通信电路和用于发送和接收RF信号的天线装置,该天线装置具有位于该电路的一个或多个周边附近的可选天线元件 板。 第一天线元件产生第一定向辐射图; 第二天线元件产生偏离第一辐射图案的第二定向辐射图。 天线元件可以包括被配置为提供增益并扩大天线元件的频率响应的一个或多个反射器。 开关网络将一个或多个可选元件耦合到通信电路,并提供阻抗匹配,而不管天线元件中哪一个或多少个被选择。 选择天线元件的不同组合导致可配置的辐射图; 或者,选择几个元素可以导致全向辐射图。
