Abstract

A security lock includes a first lock component lockingly engagable within a second lock component. Locking engagement is provided by way of a deformable latch member on the first lock component engaging a latch retainer on the second lock component. The second lock component has a key-receiving configuration that accepts a key. The key is configured to deform the latch member in order to release the first lock component from the second lock component.

Abstract

A method for forming a permanent connection joint to interconnect structures. The method may include inserting a post on a first structure into a socket on a second structure, with one of the post or the socket being configured to form an integral chip retainer on the other of the post or the socket during the inserting that permanently locks the post in the socket. In another aspect, a permanent connection joint is provided. The connection joint may include a post disposed in a socket, a chip retainer integrally formed on one of the post or the socket, and a recess formed on the other of the post or the socket, the chip retainer being lockingly engaged in the recess. In example embodiments, the integral chip retainer is formed by broaching as the post is installed in the socket during connection formation.

Abstract

A manhole security cover includes a manhole cover body comprising a non-metallic RF signal transmissive material. The manhole cover body is seatable on a manhole frame to cover a manhole opening. In the seated position, the first side is accessible from outside the manhole, the second side is disposed within the manhole, and the peripheral edge portion engages a manhole cover support surface on the manhole frame. A manhole cover tamper sensor is responsive to a predetermined movement of the manhole security cover body. A transmitter is operatively connected to the manhole cover tamper sensor and configured to generate a radio frequency manhole cover tamper signal when the manhole cover tamper sensor detects the predetermined movement of the manhole security cover body. An antenna is operatively coupled to the transmitter to radiate radio frequency energy through the manhole cover body to a receiver located outside of said manhole.
