  • Vehicle chassis control with coordinated brake and steering control on split coefficient surface
    Patent number: 6681167
    Abstract: A vehicle chassis control stores first and second calibrated values of a predetermined braking parameter and a steering correction parameter. The control includes apparatus for detecting a split coefficient condition with respect to the road surface; and, when it does and a braking signal is present, the control actuates braking apparatus for a wheel on the side of the vehicle having the higher coefficient of friction with the first calibrated value of the predetermined braking parameter and simultaneously actuates the steering apparatus with a steering correction to compensate for yaw induced by braking on the split coefficient road surface. If the steering correction is not available, however, the braking apparatus is actuated for the wheel having the higher coefficient of friction with the second calibrated value of the predetermined braking parameter without simultaneously actuating the steering apparatus with the steering correction.

  • Heated toilet seat
    Patent number: 5940895
    Abstract: A heated toilet seat with an outer clam shell type housing and an inner clam shell type housing. A heater wire is positioned in the inner housing to distribute heat. The inner housing is held above the bottom portion of the seat so that little heat is wasted by passing down through the bottom portion. The inner housing can be of essentially the same geometric configuration as the top and bottom portions of the outer housing, and groove and rib structures can tightly enclose the wiring in the inner housing.
