  • Publication number: 20130298324
    Abstract: A waterless toilet system with fece and urine separation, odor and vermin seal, thermal and biological disinfection, and gas ozonation includes a system of components. The feces and urine are kept separate by a ridge separating the urine bowl from the fece chute. The seat forms a temporary seal with the platform, and the lid forms a temporary seal with the seat when closed. The rest of the components are sealed to keep vermin outside and odors inside, with the exception of a gas vent hose with a screened opening. Biological disinfection is achieved with phage focused on human pathogens. Thermal disinfection of human pathogens is achieved by insulating the fece receptacle and containing metabolic heat. The air in the toilet is ozonated by electrical discharges from a hand operated device.

  • Patent number: 6106038
    Abstract: A collision damage reduction system to reduce contact velocities between a vehicle and a collidant by use of air bags on the exterior of the vehicle. The vehicle operator or an automatic collision imminence detection system e.g. radar, sonar, or an accelerometer and controller actuates a switch that actuates the air bag inflators when a collision is perceived imminent. The switch or controller can also interrupt vehicle motive power and actuate the brakes. The air bag has vents and shapes to steer it and its collidants. The controller can also actuate vehicle horns and lights to warn collidants when imminent collisions are detected.
