Latest Patents

One of Song Li's latest patents is a driving device and method. This invention includes a light emitter, a biasing circuit, a light receiver, an automatic control system, and an alternating current (AC) path. The light emitter generates an optical signal, while the biasing circuit produces a driving signal to activate the light emitter within a specific working range. The light receiver detects the output power of the optical signal, generating a corresponding electrical signal. The automatic control system adjusts the driving signal based on this electrical signal to ensure the output power of the optical signal approaches a preset value. The AC path connects the light emitter to an external signal source, allowing it to receive at least one AC modulated signal, resulting in the generation of modulated optical signals.

Another notable patent is related to systems and methods for distance measurement. This invention features a light signal generator with a first emission unit that outputs a light beam to a target based on a first frequency-modulation signal. Additionally, a light-mixing unit generates a light mixing signal from a second frequency-modulated signal and a reflection light beam from the target. An electrical mixing unit creates an electrical mixing signal based on both frequency-modulation signals. A processing unit then performs phase difference estimation to determine the distance between the target and the measurement system, compensating for the evaluated distance based on the amplitude of the reflection light beam.
