  • Patent number: 8943871
    Abstract: A crash sled system for simulating the deceleration and pitching motion associated with vehicle crashes. A main sled is accelerated in accordance with vehicle deceleration that occurred during a crash event. A pitching platform is located above and moves with the main sled. Forward and rear guide assemblies are provided which are located along the sides of the pitching platform when the main sled and pitching platform are in the pre-launch position. When the main sled is launched, the front and rear ends of the pitching platform travel along paths established by the guide assemblies. Prior to launch, the guide assemblies are set to angles of inclination that provide linear approximations to paths for the forward and aft ends of the pitching platform that will result in pitching motion experienced by vehicles during the crash events being simulated. Variously configured guide assemblies are disclosed that provide design trade-off between simulation accuracy and system complexity.

  • Publication number: 20130200230
    Abstract: An adjustable step ladder paint bucket holder incorporates a support plate with an angled grasping flange to be secured to a step ladder top step. An adjustable can bottom support extends from the support plate and adjustable rim supports are attached to the support plate to tangentially receive the circumference of the can. An adjustable hook receives a handle on the can to secure the can to the holder.

During launch, the front and rear ends of the pitching platform travel along paths established by the guide assemblies. Prior to launch, the guide assemblies are set to angles of inclination that provide linear approximations to paths for the forward and all ends of the pitching platform that will result in pitching motion experienced by vehicles during the crash events being simulated. Variously configured guide assemblies are disclosed that provide design trade-off between simulation accuracy and system complexity.

  • Patent number: 6957715
    Abstract: A sound producing rock having a matching body and a cap such that the cap is supported above the body in a spaced relationship to give the illusion that the cap and body are a monolithic structure. The cap and body are produced by sawing the cap from the body. A cavity is formed in the body by drilling a borehole in the body which extends downwardly from the flat body surface. A speaker is mounted in the cavity to project sound upwardly against the flat surface of the cap so that sound is projected outwardly from the space formed between the cap and body.
