Abstract: A torque device can provide more control of the guidewire with less user effort. The torque device may include a first member, a second member, and a connecting member that couples the first member and the second member; and a locking member slidably coupled to the first member and/or the second member. The locking member may be configured to move along at least a portion of a side of the first member and the second member between one or more positions corresponding to operation states. The operation states may include a closed state in which the side of the first member and of the second member are fixedly secured with respect to the locking member, and one or more open states in which at least a portion of the side of first member and at least a portion of the side of the second member are separated.

Abstract: A strip material (18) for forming an inductive loop (10) adapted to be applied to the surface of a roadway (12). The strip material (18) consists of and the loop (10) is formed from a ductile, flexible, flattened, extensible conductor (20) and a protective covering (22). A protective underlayment (24) is optional. The conductor (20) may be formed from a compressed, flattened metallic wire braid (28) or from a wire mesh containing 25% to 75% voids. The protective covering (22) may be formed from either combination unvulcanized elastomer precursor base sheet (30) and a vinyl based polymer support film (32), or a covering (26) selected from the group of epoxy, polyester, urethane and polyurethane.

Abstract: Means for hinging or removably attaching a cover to a chassis comprising a retainer device including a pair of arms spring-urged away from one another. The retainer device is fixed to the chassis with the ends of the arms extending outward into openings in the cover. The arms can be manually pinched to disengage them from the cover openings to thereby permit the cover to be removed from the chassis. Utilization of a pair of retainer devices on the chassis enables one of the devices to be disengaged while the other remains engaged to thus hinge the cover relative to the chassis.
