Latest Patents

One of his latest inventions is an infrasound generating device based on a displacement-feedback type vibration exciter. This device comprises a displacement-feedback type vibration exciter system, an infrasound generating chamber, and a laser vibrometer. The system utilizes a displacement feedback mechanism to achieve a standard infrasonic pressure signal with low harmonic distortion. The piston is driven by the vibration exciter to move sinusoidally within the airtight infrasound generating chamber. The laser vibrometer measures the displacement of the moving part, allowing for precise calibration of infrasound sensors. This invention boasts advantages such as technical maturity, high feasibility, and calibration accuracy.

Another notable patent is the vibration exciter system with a feedback control unit based on an optical linear encoder. This system includes a vibration exciter, a signal generator, and a power amplifier. The optical linear encoder converts the displacement of the moving component into A/B pulses, which are then processed to produce a standard signal. This standard signal is used to drive the vibration exciter, ensuring accurate performance.
