The disclosed water barrier systems may include a first mobile water barrier, and adjacent second mobile water barrier, and a translation mechanism for translating the first mobile water barrier and the second mobile water barrier toward each other. Lowering mechanisms may be configured to lower sidewalls of the mobile water barriers. The mobile water barriers may include sealing elements to form water seals between the adjacent mobile water barriers and between the sidewalls and a surface. Related methods of forming a water barrier assembly are also disclosed.

A movable body includes an imaging system which acquires an image formed by a terahertz wave, wherein the image is an image obtained by capturing an inspection object inside the movable body.

A fall arrest system for arresting the fall of a user. The system may arrest movement of a worker after falling from an elevated work surface. The system may include a rail; a trolley having a body in rollable contact with the rail, a brake sub-system, and a plurality of wheels. The brake sub-system may include a brake rod, a brake pad connected to the brake rod, a lanyard connector connected to the brake rod, and a resilient element. The brake rod may be slidably coupled to the body so that the brake sub-system is alterable between: (1) a free state in which the brake pad is spaced a distance above the rail; and (2) an arrest state in which at least a portion of the brake pad frictionally engages the rail. The resilient element may bias the brake sub-system into the free state.
