Latest Patents
One of her latest patents is the "Fluid particle sensor apparatus and method for detecting ferrous and non-ferrous metals." This invention features a sensor apparatus designed to detect both ferrous and non-ferrous particles in a fluid. The apparatus includes a housing that can be inserted into a fluid line, with a collection cavity that traps metallic particles suspended in the fluid. The design incorporates two coils that respond to the temperature of the fluid and the accumulation of particles, allowing for precise measurements. Additionally, an electromagnetic coil is used to attract ferrous particles, enhancing the sensor's functionality. The microprocessor connected to the coils calculates the percentage of ferrous and non-ferrous particles, providing valuable data for diagnostic and prognostic analysis.
Another notable patent is the "Inductive sensing apparatus for a hydraulic cylinder." This invention determines the extended length of a hydraulic cylinder using a coil wound around the rod, which moves with the piston. An oscillator produces a position signal based on the inductance of the coil, allowing for accurate measurement of the piston and rod's position and velocity relative to the housing.
