Title: Chieh-Hsun Hsiao: Innovator in Wireless Detection Technologies

Introduction

Chieh-Hsun Hsiao is a prominent inventor based in Kaohsiung, Taiwan. He has made significant contributions to the field of wireless detection technologies, holding three patents that showcase his innovative spirit and technical expertise. His work has implications for various applications, particularly in communication and signal processing.

Latest Patents

One of Hsiao's latest patents is a wireless detection apparatus and method. This apparatus includes an antenna, a voltage control oscillator, and a processing unit. The antenna receives a first wireless signal and generates an electrical signal based on that signal. The first wireless signal is produced by reflecting a second wireless signal from an object under test. The voltage control oscillator is connected to the antenna to generate an oscillating signal influenced by the electrical signal. This oscillating signal changes with variations in the electrical signal. The processing unit evaluates a parameter of the object under test based on the oscillating signal's variations.

Another notable patent is the polar receiver using injection-locking technique. This receiver comprises an antenna, a first filter, a first voltage-controlled oscillator, a first mixer, a frequency discriminator, two additional filters, and two analog-digital converters, along with a digital signal processing unit. This polar receiver effectively separates an envelope signal and a frequency-modulated signal from a radio frequency signal received by the antenna. The separation is achieved through the injection locking technique of the first voltage-controlled oscillator and the frequency discriminator. The envelope and frequency-modulated components can be digitally processed by the digital signal processing unit to accomplish polar demodulation.
