Abstract: A monitor configured to be removably coupled to a strut that forms part of a temporary support structure. The monitor may include an electronic monitoring device that includes a load cell. The monitor may be configured to be position in-line with strut and subject to the same forces exerted upon the strut. Further the monitor may be configured to wirelessly communicate the sensor information to a user.

Abstract: An adjustable strut that includes an outer housing configured to receive an extendable member, and an extending mechanism with a gear system configured to convert rotation motion of an input mechanism into linear translation of the extendable member.

Abstract: An air pressure controller having an inlet and an outlet, the controller may be configured to reduce air pressure between the inlet and the outlet and includes an exhaust port configured to exhaust air if a pressure at the outlet rises above a predetermined level.

Abstract: A lifting device including a recessed inlet molded into an envelope structure of the lifting device at a notch section. The notch section, in turn, may include one or more protruding surfaces configured to protect the inlet, or air hose coupling attached to the inlet, from contact (e.g. falls/bumps) that may otherwise damage one or more of the air hose coupling or the recessed inlet while the lifting device is being stored, deployed, or used.

Abstract: A shaft adapter configured to be removably-coupled to shafts of differing diameters. The shaft adapter may have a stepped cylinder cavity with multiple inner diameters. The shaft adapter may further have a spring-loaded adapter ring configured to translate along an inner wall of the stepped cylinder cavity, and may be configured to support an outer wall of a first shaft received into the shaft adapter, or may be configured to be urged into a compressed position when the shaft adapter receives a second shaft.

Abstract: A lifting device, configured to expand in a first direction between a deflated configuration and an inflated configuration upon being filled with compressed gas, may have a continuous surface including a bottom surface, a lower and upper intermediate surfaces and a top surface. A bottom plate may be coupled to at least part of bottom surface and a top plate may be coupled to at least part of the top surface. The continuous surface may include a plurality of surface undulations that provide a low height profile when in the deflated configuration and a higher height profile when in the inflated configuration. The plurality of surface undulations may vary between a first and second height when in the deflated configuration, but in the inflated configuration the variance between the relative heights of any remaining undulations is relatively smaller.

Abstract: An adjustable strut having a locking mechanism configured to removably-secure a pair of telescopic structural members to one another when positioned in a contracted configuration for transport and storage. Further, the locking mechanism allows for fast and intuitive unlocking of the pair of telescopic structural members for adjustment of a length of the strut for structural bracing.

Abstract: A manual emergency tool assembly including a pair of tools, each of which has an operating head and a handle. The handles are formed to be telescopically engaged with each other. A locking arrangement is provided to secure the handles to each other in a fully telescoped relationship, and in intermediated telescoped relationships. A further locking arrangement provides for limited axial movement of the handles with respect to each other. The locking arrangement also provides for separating the tools for independent use of each tool or for use of the tools together in a configuration other than with the handle in a telescopic relationship.

Abstract: A hand-held pneumatic rescue tool may be driven from a bottled compressed gas. The driving gas is used only for the blow-striking stroke, while a compression spring is used to provide a force for the return stroke that is independent of the pressure of the driving gas. Thus, the pressure of the driving gas may be varied to adjust the impact force of the blows struck, without adversely affecting operation of the tool. By appropriate valving, the tool will operate continuously and automatically so long as driving gas is supplied, as determined by the operator.

Abstract: Control valves for a plurality of outlets supplied from a single fluid source are combined in a single manifold. Each outlet conduit is selectively connected to an inlet conduit by an independently actuatable source valve. Each outlet conduit is also provided with an independently actuatable discharge valve and a safety relief valve. A pressure gauge may also be connected to each of the outlet conduits. The conduits may be channels formed in a solid manifold, and the independently actuatable valves may be manually actuatable push button valves. A locking mechanism is provided for each of the push button valves.

Abstract: A rescue tool with an extended hollow housing has the shaft of a tool bit mounted in one end thereof for reciprocable motion. A substantially solid hammer is manually driven to strike the tool bit, the hammer extending the greater portion of the length of the housing when striking the tool bit. Manual actuation of the hammer is achieved by means of a shroud having a handgrip on its outer surface, the shroud being secured to the hammer at the end away from the tool bit. The hammer may be locked with respect to the housing to provide a pry bar of two different lengths. Securing the hammer to prevent complete withdrawal of the hammer from the housing is achieved by an easily removable snap ring arrangement.
