Abstract: A protector for protecting aircraft, particularly helicopter rotor blades, from absorbing the sun's infrared rays and the accompanying heat build-up in order to keep adhesive material between spar connections from debonding and to avoid delamination from the rotor blade's composite skin. The rotor blade protector includes a cover configured to encircle the length of the rotor blade and a guide form for installing and removing the cover. The inner surface of the cover is coated, by vacuum deposition technology, with aluminum, titanium, or other metals or alloys. The coating thickness will be in the order of 9-30 billionths of a meter thick. A stripper rod is attached to the guide so that aircraft personnel can install and remove the protector from the helicopter rotor blade while standing on the ground. Optionally, a series of ribs can be provided along the cover to provide increased air insulation around the rotor blade.

Abstract: A helmet restraint device for operationally securing a helmet worn by a driver, pilot, or occupant of a high-performance vehicle (such as a racecar, aircraft, or boat) to the vehicle's seat belt assembly. The helmet restraint device reduces potentially injurious forces to the occupant's head and neck during high-deceleration of the vehicle, particularly a frontal collision. The helmet restraint device includes a high strength, lightweight rod disposed behind and below the occupant's neck, just beneath the shoulder harness, and a strap that attaches between the occupant's helmet and the rod. The strap is connected to the helmet via attachments in the helmet and a cable assembly so as to allow the occupant's head to move freely from side to side.

Abstract: A disc golf target having an improved configuration for providing uniform, more consistent disc capture. The target includes a canopy assembly and a basket assembly attached to a center pole. A tripod base is used to support the target. A chain assembly is attached between the canopy and basket assemblies for absorbing kinetic energy from an incoming disc thereby capturing the disc. The chain assembly includes a continuous upper chain, attached to the canopy assembly and extending 360 degrees, a plurality of deflection members hanging from the upper chains, and a continuous lower chain functionally coupled to the lower end of said deflection members. The deflection members are attached to the canopy and basket assemblies in an alternating pattern in which a first deflection members are attached at the canopy assembly and adjacent second deflection members are attached at the basket assembly. The canopy and basket assemblies are quickly collapsible.
