Latest Patents
Farstad's latest patents include a piezoelectric transducer for measuring instantaneous vibration velocity. This innovative device employs a stack of piezoelectric crystals interposed between electrodes and maintained under compression. It develops an electrical charge that corresponds to the acceleration of the device. The output charge, which is proportional to the velocity of the device, is delivered to a charge converter that can be located remotely. This assembly allows for the use of high-sensitivity piezoelectric crystals.
Another notable patent is the low-frequency, high-sensitivity electromechanical transducer. This device utilizes an Eddy current type displacement sensing device mounted in relation to a seismically supported, nonmagnetic metal beam within an enclosed chamber. The movement of the metal beam is damped, and its instantaneous displacement is proportional to the instantaneous acceleration applied to the transducer. The output electrical signal can be integrated to provide a signal directly proportional to the instantaneous velocity of the transducer.
