Abstract: A barrier system which provides a new and unique approach to separating traffic and provides a safe, convenient and effective means of controlling traffic. Segmented continuous interlocking barriers embedded in the roadway rise out of the roadway to prevent head-on collisions between opposing lanes of traffic to aid in the prevention of serious accidents and loss of life on any undivided roadway on a suspension or truss bridge. All electro-mechanical mechanisms are controlled by PLC programmable controllers, automation software and a data processor control system link with mobile end-system wireless link compatibles in a multi-capability environment to perform the electro-mechanical tasks in altering traffic lane configurations. A set performance schedule is set up according to traffic flow by user in the alternating of its mechanical barrier devices in sequential order, with means from pneumatic air cylinders.

Abstract: A locking apparatus secures a portable hand held object such as a tape measure to a support strip such as the belt of a wearer, some other portion of a wearer's clothing, or a wearer's tool pouch. The apparatus is constructed to provide full encirclement of the belt or other support, eliminating the danger of inadvertent dislodgement while permitting one-hand release. The apparatus consists of a plate bent over at one end to form a lip and at the other to form an angled extension, and mounted in a spring-biased manner to the lateral face of the object such that the lip abuts the lateral face while the angled extension extends over the top, leaving the gap between the plate and the lateral face to receive the belt and a further gap between the angled extension and the top surface of the object to permit manipulation by compressing with the heel of one's hand while one's fingers grip the bottom surface of the object.
