Latest Patents
Among Ernst H. Nordholt's latest patents is a groundbreaking design for a voltage-controlled oscillator featuring a resonant network. This invention includes an amplifier and a reactive network integrated into an oscillator loop. The reactive network is equipped with reactive components whose values vary based on a control signal fed into a control input, enabling the regulation of the oscillator frequency in accordance with the control signal. Additionally, a control loop is established between the resonant network and the reactive network, determining the difference between the measurement of the imaginary part of the impedance or admittance of the resonant network and the control signal that serves as a reference quantity. This technological advancement incorporates a derivation circuit and a differential amplifier to ensure precise functioning.
In the realm of sensors, Nordholt has developed an inductive proximity sensor designed to detect objects with electrical conductivity. This sensor consists of a housing, a measuring coil, and a reference coil symmetrically positioned around a central plane. Each coil is partially encased with magnetic material, optimizing detection efficiency as objects approach. The sensor employs an electronic circuit to apply an AC signal to both coils while measuring variations in specific properties, facilitating accurate identification of object presence or distance. Moreover, the design integrates means for screening magnetic fields to mitigate mutual crosstalk, along with separate synchronous detectors containing frequency-selective measurement capabilities.
