Latest Patents
One of Crosby's latest patents is a proximity sensor featuring a non-ferrous metal shield designed to enhance sensing capabilities. This innovative proximity sensor includes a transducer and a circuit with a switch that changes state in response to the presence of an object near the transducer. The transducer is equipped with a magnetic form that defines a generally planar surface facing the sensing zone. Additionally, the magnetic form has a side surface extending away from the sensing zone and an internal cavity that opens toward the sensing zone. A sensing coil is strategically positioned within this cavity. The sensor housing supports both the sensing coil and the magnetic form in relation to the sensing zone. The non-ferrous metal shield surrounds part of the magnetic form, enhancing the sensor's range by having an edge that aligns with the planar surface of the magnetic form. Another notable patent is a power supply that connects the rectified output of multiple transformer secondaries in series and parallel for each half cycle of an alternating current energization signal. The logic circuitry monitors the output and automatically switches connections to ensure a regulated power supply output.
