Latest Patents
One of Pieper's latest patents is the "Stagnation Sensing Control." This invention is designed to determine when a gas turbine engine has stagnated during the start phase of operation. It includes mechanisms for sampling engine speed at a predetermined point in time and holding that speed in memory. The system compares the engine speed at a later point in time with the stored speed, producing an engine shutdown signal if the speed increase is less than an established threshold.
Another notable patent is the "Torquemeter Circuit." This circuit generates a potential indicative of torque by responding to the phase angle between AC signals from two generating coils. These coils are excited by toothed wheels connected to different points along a shaft transmitting power between an engine and its load. The circuit is designed to be insensitive to variations in speed and ambient temperature, making it a reliable tool for torque measurement.
