Abstract: An assembly for adaptively controlling vibration, shock, acceleration and position of an item mounted to the assembly independent of varying operating characteristics of the item or a support base for the assembly is provided. The assembly comprises an item to be controlled, a support platform for supporting the item, a viscous spring damper mechanically intercoupled between the item and the platform, a first accelerometer for sensing vibration, shock, acceleration and position of the item, a second accelerometer for sensing vibration, shock, acceleration and position of the support platform, a gas supply source for selectively supplying gas to the viscous spring damper, a fluid supply source for selectively supplying fluid to the viscous spring damper, and a logic control circuit for adjusting inputs from the gas supply source and the fluid supply source to selectively adjust the operation of the viscous spring damper and the dynamic mechanical coupling of the item to the platform.

Abstract: A self powered tire condition indicator system is disclosed. The system comprises a plurality of wheel mounted transmitting assemblies which communicate by a radio frequency transmission to a receiver located within the operator compartment of a vehicle. Each of the transmitting assemblies generates its own transmitting power by converting the mechanical compression of a flat tire into electrical energy. The electrical energy is used to generate an intermittent characteristic tone associated with a deflated tire condition by the frequency modulation of a carrier.
