Title: Innovations of Robert B Gelenius
Introduction
Robert B Gelenius is an accomplished inventor based in Davison, MI (US). He has made significant contributions to technology, holding a total of 3 patents. His work primarily focuses on innovative solutions in detection systems and motor drive technology.
Latest Patents
One of his latest patents is a threshold detector for a condition indication. This invention features a capacitive probe that senses the presence of water in a fuel tank. The probe increases in capacitance when water is present, and the threshold detector circuit includes the capacitive probe, a reference capacitor, and an oscillator. This setup periodically charges them to the same voltage, while a comparator determines when the probe capacitance exceeds the reference capacitance. The comparator controls a lamp driver connected to a remote indicating lamp, which is powered through a single conductor. This design allows for partial regulation of the voltage presented to the detector circuit, ensuring stability despite changes in power supply voltage.
Another notable patent is a commutatorless direct current motor drive system. This system initiates the rotation of a permanent magnet rotor from a standstill upon the application of supply potential. It sustains rotor rotation by sequentially energizing the polyphase stator phase windings in response to the alternating current potential waveforms induced by the rotor's magnetic field.
