Title: Chia-Chi Chang: Innovator in Weighing Systems and Automatic Detection Technologies

Introduction

Chia-Chi Chang is a notable inventor based in Tainan, Taiwan. He has made significant contributions to the fields of weighing systems and automatic detection technologies. With a total of 3 patents, his work showcases innovative solutions that enhance functionality and efficiency.

Latest Patents

One of Chia-Chi Chang's latest patents is a weighing system that includes a processor, a display, a reader, a switch, a scale, a memory device, intake-type buttons, and output-type buttons connected to the processor. This system allows the processor to control the display to show an identification number obtained by reading an identifier. The switch enables the processor to operate in either intake or output mode, displaying corresponding symbols based on user interaction. The processor also manages weight data from the scale, storing pre-intake and post-output weight values in the memory device.

Another significant patent is an automatic detecting method and apparatus. This apparatus comprises an inputting unit, a dividing unit, a contouring unit, a range analyzing unit, a boundary analyzing unit, an edge detecting unit, an expanding unit, and an overlapping unit. The dividing unit segments an overlooking image into four clusters using a clustering algorithm. The contouring unit obtains a contour, while the range analyzing unit determines a detecting range. The boundary analyzing unit identifies a circular boundary, and the edge detecting unit finds multiple edges within that boundary. The expanding unit expands these edges, and the overlapping unit combines the expanded edges with the contour to create a defect pattern.
