Abstract: A system and method is provided for use in a control system, such as a steering control system, for validating quadrature signals. A system makes a determination of validity based on the timing of detected state changes in the quadrature signals. To accomplish this, the amount of time that elapses between successive transitions is compared to the amount of time that elapses in an adjacent time period. If the two time periods are close enough, the signals are considered valid.

Abstract: The present invention is a transparent deodorant cosmetic stick product with at least 3.5% by weight of the formulation being an alkali metal bicarbonate. The product contains about 1.25% to about 6.5% of a polyamine as a mandatory clarifying component. Other required components of the formulation are a polyhydric alcohol, a C.sub.14-22 fatty acid salt, of a clarifier surfactant, and less than about 42% by weight water. Optional ingredients include antibacterial or bacteriostatic agents, a silicone copolyol, zinc pyridinethiol oxide, fragrance and color.
