    摘要: A door includes a rectangular panel having a first face, a second face, and two pairs of opposing edges, in which the edges of each pair of edges are parallel and in which a first pair of edges is longer than a second pair of edges. The rectangular panel includes a layered composite material, in which a first layer of the composite material has a positive Poisson's ratio (PPR) and a second layer of the composite material is disposed in contact with the first layer and that includes a material having a negative Poisson's ratio (NPR). The door includes a hinge including plates joined together by a joint, in which a first one of the plates is attached to a first one of the edges of the first pair of edges and in which a second one of the plates extends beyond the first one of the edges. The door also includes a handle opening defined through a thickness of the rectangular panel.

    摘要: A security system having a device that attach directly to and locks on or around an object to be secured, or one or more parts of the system are integrated into a full or partial enclosure that fully or partially encloses or surrounds the object to be secured, that cannot be removed from the object or enclosure without disengaging the locking mechanism through a provided method, and when the device is attached to the object or integrated into the enclosure, the system renders the object unusable for its intended use, and the system is capable of determining location, has a radio transmitter and/or transceiver capable of processing, transmitting and/or relaying information, data and images over terrestrial and/or satellite communication networks, and can include various sensors and other data and image gathering methods, and can contain an audible alarm.

    摘要: The anti-theft device is configured in a door lock, and contains a first blocking piece, a second blocking device, a positioning piece, and a lever. The first blocking piece contains a first section and a second section bended and extended perpendicularly from the first section. The first section has a first through hole and a second through hole. The lever is engaged by a lock heart of the door lock. When the door lock is locked, the lock heart is turned to engage the lever so that the lever drives the first blocking piece downward by its first through hole. The second section of the first blocking piece as such blocks a lock tongue of the door lock so that the door lock cannot be opened without using key.
