Latest Patents

One of Liu's latest patents is a power on reset circuit. This circuit includes a bias current generation module for generating a bias current, a power on reset module for generating a power on reset voltage signal, and a feedback latch module, which are electrically connected in sequence. The power on reset module features two series switches that can be turned on or off to adjust the bias current, thereby further adjusting the power on reset time. The feedback latch module is designed to latch the power on reset voltage signal, helping to restrain the jitter of the power voltage within the input voltage range of inverters in the power on stage and to avoid signal jumps. This module comprises a feedback branch formed by two NMOS transistors in series connection, achieving a rapid and stable output of the power on reset voltage signal through feedback.

Another notable patent is an aligning and matching system and method for wireless charging of automobiles. This invention includes a wireless charging receiver equipped with a receiving coil and an aligning detection module that features a first magnetic sensor chip array and a first solenoid set, which is positioned on the lower portion of an electric automobile. The wireless charging transmitter consists of a wireless transmitting panel with a transmitting coil, a matching detection module that includes a photosensitive chip array, a second magnetic sensor chip array, and a second solenoid set, along with a driving device for moving the wireless transmitting panel. The magnetic sensor chips and solenoids are strategically placed around the receiving coil to enhance the efficiency of the wireless charging process.
