摘要： A protection system (80) for a first generator unit (12) connectible by a first switch (24) to a power generating system having at least one additional generator unit with the at least one additional generator unit being connectible in parallel to the first generator unit with the first switch being opened in response to a first control signal to enable the first generator unit to be disconnected from the parallel connection to the at least one additional generator unit in accordance with the invention includes a signal generator (12) for generating a reference signal having a frequency proportional to a frequency of a voltage generated by the first generator unit; a sensor (14) for sensing a common frequency at a point of reference of voltage generated by the generator units of the power generating system; and a controller (14) responsive to the signal generator and the sensor, for calculating a difference between the frequency of the reference signal and the common frequency and for generating the first control signal in response to the difference being greater than a threshold.
摘要翻译：一种用于第一发电机单元（12）的保护系统（80），其可由第一开关（24）连接到具有至少一个附加发电机单元的发电系统，所述至少一个附加发电机单元可与第一发电机并联连接单元，其中第一开关响应于第一控制信号而被打开，以使得第一发电机单元能够从与所述至少一个附加发电机单元的并联连接断开，根据本发明包括一个信号发生器（12）参考信号具有与由第一发生器单元产生的电压的频率成比例的频率; 传感器（14），用于感测由所述发电系统的发电机单元产生的电压的参考点处的公共频率; 以及响应于所述信号发生器和所述传感器的控制器（14），用于计算所述参考信号的频率与所述公共频率之间的差，并且响应于所述差大于阈值来产生所述第一控制信号。

摘要： A method and apparatus for tamper resistant packaging comprises a container (102) having a top (106), and a bottom (108). The container has a shape such that a top container perimeter has a first length, and a bottom container perimeter has a second length which is great than the first length. The container also has a tab (124) extending outward from a side surface of the container. The packaging further comprises a sleeve (104) adapted to slide over the top of the container, the sleeve having a bottom opening that has a sleeve bottom perimeter that has a third length that is greater than the first length and less than the second length such that the sleeve will not slide over the bottom of the container. The sleeve includes an engaging member (132) adapted to engage the tab.
摘要翻译：用于防篡改包装的方法和装置包括具有顶部（106）和底部（108）的容器（102）。容器具有使顶部容器周边具有第一长度的形状，并且底部容器周边具有大于第一长度的第二长度。容器还具有从容器的侧表面向外延伸的突片（124）。所述包装还包括适于在所述容器的顶部上滑动的套筒（104），所述套筒具有底部开口，所述底部开口具有套筒底部周边，所述底部周边具有大于所述第一长度且小于所述第二长度的第三长度，套筒不会滑过容器的底部。套筒包括适于接合突片的接合构件（132）。
