  • Publication number: 20070045309
    Abstract: 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.

  • Patent number: 4953052
    Abstract: 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 con
