Title: **Innovative Contributions of Cheng-Nan Tsai in Smoke Detection Technology**

Introduction

Cheng-Nan Tsai, a prominent inventor hailing from Hsin-Chu County, Taiwan, has made significant advancements in the field of smoke detection technology. With a total of 27 patents to his name, Tsai's work reflects a deep commitment to enhancing safety and efficiency in smoke detection systems.

Latest Patents

Among his latest patents, two notable innovations stand out. The first is a **smoke detector having a light source surrounded by a wall with varied heights**. This innovative smoke detector design includes a substrate, a light source, and a light sensor. The asymmetric structure of the substrate is strategically designed to cause the illumination region of the light source to deviate toward the light sensor. This arrangement effectively increases the ratio of light intensity reflected by smoke in comparison to a reference light intensity.

The second patent is for an **optical machine of a smoke detector**. This optical machine features a substrate, a light source, a light sensor, and a light-blocking member. Here, the light source and light sensor are arranged in a specific first direction, while the light-blocking member strategically obstructs part of the emission angle of the light source, directing the remaining light toward the light sensor, hence enhancing the detection capabilities.
