  • Patent number: 11123250
    Abstract: A powered ambulance cot and methods of raising and lowering the cot as well as loading and unloading the cot are disclosed. The cot includes a support frame and legs, each leg having a wheel. An actuator of an actuation system interconnects the frame and legs, and is configured to effect changes in elevation of the frame relative to the wheel of each of the legs. A control system controls activation of the actuation system, and detects both the actuator at a first location relative to the frame, where the first location is remote from a second location and which situates an end of the actuator that is remote from each wheel closer to the frame, and a presence of a signal requesting a change in elevation of said support frame to thereby cause the legs to move relative to the support frame.

  • Patent number: 5876023
    Abstract: An insert used to connect aircraft floor panels, and the like, to supporting structure includes features which function to isolate the supported panel from vibrations in the supporting structure. The isolation of the panels leads to reductions in SIL (Speech Interference Level) noise within aircraft cabins. The insert consists of internal and external rigid components separated by a contoured elastomeric component. The elastomeric component is preloaded when installed via a fastener extending through the inner rigid component and attaching to the supporting structure. The outer and inner rigid components are sized such that the inner rigid component will not pass through the outer rigid component, thus providing a safetied installation of the panel. The elastomeric component extends below the bottom of the outer rigid component and provides soft snubbing against the supporting structure during loading of the panels. This allows some level of isolation while restricting motion of the panels.

  • Patent number: 4747475
    Abstract: The capability of this shock absorber or damper changing the energy of motion into heat progressively increases as the suspension components progressively wear and become more flexible over their service life. This is accomplished by the use of flow controlling concentric seats of different heights on the rebound valve element. As the outer and higher seat wears down, the working area of the valve element decreases with the inner seat being operative to increase the load to generally compensate for the reduction in friction in the suspension thereby providing a more consistent ride as a function of use.
