Introduction
Chun-Fang Xi is a notable inventor based in Shenzhen, China. He holds a total of 8 patents that showcase his contributions to the field of technology. His work primarily focuses on developing advanced electronic devices and circuits.
Latest Patents
One of his latest patents is a digital multimeter. This device includes a single chip processor, a sound chip connected to the processor, a signal amplifying circuit, a speaker, and a power source. The single chip processor collects high and low level signals, converts them into codes recognized by the sound chip, and transmits these codes. The sound chip then converts the codes into audio signals, which are amplified by the signal amplifying circuit and output through the speaker. The amplified audio signals report the measurement values of the digital multimeter.
Another significant patent is a circuit for detecting computer states. This circuit can identify various states of a computer, including S3 and S4 states. When the computer is in an S3 state, a specific pin is at a low level, while another pin is at a high level. A light-emitting diode indicates the S3 state by emitting light. The circuit also detects other states such as network state, hard disk state, and low power state through additional light-emitting diodes.
