    • A traffic control marker includes an elongate flexible arrow member arranged for positioning upon a road surface to direct traffic flow therethrough. The marker provides for a removable forward head relative to the marker for use of the arrow head relative to the marker. A modification of the invention includes suction cup members molded into the bottom wall of the marker body and arrow head, as well as reflector housings mounting reflective lenses projecting rearwardly of the marker head, with a further organization to include the reflector housing positioned medially of speed-bump type boss members that in conjunction with the reflector housing are orthogonally oriented relative to the side walls of the body as a one-piece assembly.
    • 交通控制标记包括布置成定位在路面上以引导交通流过其中的细长柔性箭头部件。 标记提供相对于标记的可移除的前头,用于相对于标记使用箭头。 本发明的修改包括模制到标记物本体和箭头的底壁中的吸盘构件以及安装反射透镜从标记头向后突出的反射镜壳体,其另外的组织包括位于中间位置的反射器壳体 与反射器壳体相结合的凹凸型凸台部件作为一体式组件相对于主体的侧壁正交定向。

    • An apparatus is provided for monitoring the location of a person and for determining whether the person is in distress. The apparatus includes a transmitter and a transceiver, which are adapted to be worn at different locations on the person's body. The transmitter normally transmits a first electromagnetic signal, which is detectable by the transceiver and by at least one remote receiver. When the person is in distress, the transmitter transmits a second electromagnetic signal in lieu of the first signal. The transceiver is responsive to the second signal for generating a third electromagnetic signal, which also indicates that the person is in distress. The remote receiver is responsive to either or both of the second and third signals for generating an alarm signal indicating the distress condition. The transceiver also generates the third signal in response to the absence of the first signal, which may occur when the transmitter is removed from the person's body and the distance between the transmitter and transceiver becomes too great for the transceiver to receive the first signal, or due to transmitter malfunctional. The third signal therefore provides a redundancy feature in the event of failure of the transmitter to generate the second signal. The apparatus not only allows the person's location to be continuously monitored, but also indicates when the person is in need of assistance.
    • 提供一种用于监视人的位置并确定该人是否处于困境的装置。 该装置包括适于佩戴在人身上的不同位置的发射器和收发器。 发射机通常发射第一电磁信号,其可由收发器和至少一个远程接收器检测。 当人遇险时,发射机发送代替第一信号的第二电磁信号。 收发器响应于第二信号以产生第三电磁信号,其也指示该人处于困扰状态。 远程接收机响应于第二和第三信号中的一个或两者,以产生指示遇险状况的报警信号。 收发器还响应于不存在第一信号而产生第三信号,当发射器从人体移除时,发射器和收发器之间的距离变得太大以致于收发器接收第一信号,或者 由于发射机故障。 因此,第三信号在发射机发生故障以产生第二信号的情况下提供冗余特征。 该装置不仅允许该人的位置被连续监视,而且还指示该人何时需要帮助。
