Latest Patents

Stafney holds a patent for a "Method of determining average current in a PWM drive." This invention provides a method for yielding the average current in a PWM driven coil for an electrohydraulic valve. The process involves transmitting a feedback signal into a Finite Impulse Response filter to take multiple signal samples. This allows for the calculation of an average value of current within one cycle. The average value is then transmitted to an algorithm that generates a pulse width signal, which drives the coil of the electrohydraulic valve in the subsequent system cycle.
