An impact attenuator safety truck with a configurable flatbed capable of carrying a forklift. The safety truck provides a crash barrier for roadway construction projects using impact absorbing sections (TMAs) that are movable from a stowage position above the surface of the flatbed, thereby allowing the entire surface of the flatbed for storage. The forklift is secured to the flatbed when the impact absorbing sections are in the stowage position. When the impact absorbing sections are in a deployed position, the forklift can access the flatbed surface from either side. A pair of hydraulic cylinders in combination with pivot arms and a cradle allows rotating of the impact absorbing sections between the stowage position and deployed position.

The aircraft can include: an airframe, a tilt mechanism, a payload housing, and can optionally include an impact attenuator, a set of ground support members (e.g., struts), a set of power sources, and a set of control elements. The airframe can include: a set of rotors and a set of support members. By utilizing a larger rotor blade area (and / or larger rotor disc area) and adjusting the blade pitch and RPM, the rotors can augment the lift generated by the aerodynamic profile of the aircraft in the forward flight mode in addition to providing forward thrust. Variants generating lift with the rotors can reduce or eliminate additional control surfaces (e.g., wing flaps, ailerons, ruddervators, elevators, rudder, etc.) on the aircraft since the thrust and motor torque is controllable (thereby indirectly controlling lift) at each rotor, thereby enabling pitch, yaw, and / or roll control during forward flight.

A crash cushion includes a first barrier frame and a second barrier frame, each having laterally spaced first and second sides defining first and second planes that slope inwardly from a top to a bottom of each side of the first and second barrier frames. The first barrier frame is movable relative to the second barrier frame in response to a head-on impact. First and second side panels are attached to the first and second sides of the first and second barrier frames, respectively, wherein the first and second side panels are movable relative to the second barrier frame in response to the head-on impact. In one embodiment, the side panels can have a variable cross-sectional shape along their length. Further, each frame can include a plurality of longitudinally spaced guides for engaging a rail.

A crash impact attenuator system for deployment in front of a structure includes a rail and a plurality of diaphragms initially disposed in spaced relation along the length of the rail. Each of the plurality of diaphragms moves along the rail, so that when a front end of the crash attenuator system receives an impact force from a vehicle, a first one of the diaphragms moves rearwardly along the rail and impacts a second one of the diaphragms so that both the first and second diaphragms move further rearwardly along the rail, this process continuing with additional ones of the diaphragms until the impact forces have been fully attenuated. A tearing member on the crash attenuator system engages material forming a side or fender panel of the crash attenuator system, the tearing member tearing material forming the side panel to attenuate the impact force.

A safety helmet, for example, usable in sports such as football, is shown and described. The safety helmet includes an outer shell and an inner shell. The latter encircles a head of a wearer of the safety helmet. The outer shell is coupled in spaced apart relation to the inner shell by impact attenuators that include in one variation elastically deformable pins. The pins protrude through the inner shell to the inner head seating structure, and outside the inner shell to the outer shell. In another version of the impact attenuators, the pins are bound to a lattice construction providing openings further accommodating deformation responsive to impact forces. Inner and outer shells may have holes to accept ends of the pins. The number of holes may exceed those actually occupied by ends of pins, thereby providing adjustability in number and location of either version of impact attenuator.
