Latest Patents

Andrew James White's latest innovations include two remarkable patents: a position sensor and a position encoder.

The **position sensor** is designed for use in a piston and cylinder assembly. This invention features a movable field modifying member that can vary the inductance of a sensor winding. By monitoring the inductance, the position of the field modifying member relative to the sensor winding can be identified. Additionally, this position sensor incorporates a compensation winding that is linked to the field modifying member. This setup allows for compensation of signal variations, such as those arising from temperature fluctuations within the system.

The **position encoder**, on the other hand, is a linear position sensor that utilizes phase quadrature sensor windings along with an excitation winding and a resonator. When an excitation current is applied, the resonator resonates and induces signals in the sensor windings. The arrangement of these sensor windings ensures that the electromagnetic coupling varies with the resonator's position, while also aligning magnetic fields involved in the sensor's operation. This alignment reduces the impact of both rotation and lateral movement, resulting in enhanced performance.
