Abstract: The present invention may provide a surge current sensor and a surge protection system that deploys one or more surge current sensors. The surge current sensor may be placed on or near to a conduit, and it may be used for sensing the surge current conducted therein. The surge current sensor may include a current transformer and a processor. The current transformer may be used for receiving a magnetic flux generated by the surge current and transforming the received magnetic flux to a voltage. The processor may be coupled with the current transformer, such that it may be configured to generate a digital signal based on the voltage. Once the digital signal indicates that the magnitude of the surge current has exceeded a predefined threshold, the surge protection system may initiate a surge protection mechanism.

Abstract: Apparatus for protecting electronic components and equipment and method of manufacturing the apparatus. A transient protection device capable of mounting onto a circuit board. The transient protection device includes first and second conductive paths. The first conductive path lies in a first plane and the second conductive path lies in a second plane spaced apart from the first plane. Furthermore, a dielectric material lies in a third plane disposed between the first and the second plane. A ground plane is coupled with said first conductive path to discharge an electrical surge.

Abstract: A hinge assembly rotatably connects one end of a cover to a phone body for rotation about a hinge axis between a closed position and an open position. The hinge assembly has a first part secured to the phone body, a second part rotatably secured to the first hinge part and rigidly secured to the cover, and a hinge release shaft secured against rotation relative to the first hinge part and extending into the second hinge part. The release shaft and second hinge part have interengageable latch formations for preventing rotation between the hinge parts when the cover is in the closed position. The release shaft is movable between an extended position in which latch formations engage and a retracted position in which the latch formations are released. A spring part rotates the cover into the open position when the latch is released. A manual override of the latch is provided.
