Latest Patents

Vajgart's latest patents include a method and apparatus for determining engine oil change intervals. This innovative system utilizes engine lubricating oil temperature and the amount of engine usage to calculate when the oil has reached the end of its predicted wear life. The process involves multiplying each spark pulse by weighting factors that are periodically determined by sampling the engine oil temperature and the duration of continuous engine use above a predetermined speed. When the accumulated weighted spark pulses reach a specific level, a warning signal is triggered to indicate the need for an oil change.

Another notable patent is the motor control circuit for motor-driven power windows. This control circuit allows for one-touch operations of the motor, enabling the associated window to automatically lower to its full down position with a brief actuation of the control switch in the 'DOWN' position. Subsequent actuation and release of the switch will interrupt and inhibit the automatic lowering of the window. Longer actuations provide direct control of the window's downward movement, while stall current sensing and excessive time sensing protect the motor and drive circuitry.
