Latest Patents

Liu Qiyuan holds a patent for an error-correcting torque sensor. This invention measures the amount of torque applied to a rotatable shaft fitted with a torsion bar between two separate shaft segments. The sensor features a first rotor attached to a first shaft segment, translating angular rotation to the rotor. A second rotor is connected to the second shaft segment, allowing for similar translation. The design includes two pairs of signal voltage references and a resistive track that extends between these references. The output voltage signals developed from the signal contacts are proportional to the relative position of the contacts between the voltage reference pairs. A method for correcting signal errors due to misalignment of the shaft segments is also provided.
