Introduction

John Wu is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of encoder technology, holding a total of 2 patents. His work focuses on improving the accuracy and reliability of detecting devices used in various applications.

Latest Patents

One of John Wu's latest patents is a detecting device of an encoder. This innovative device comprises a photodetector and a detection circuit. The photodetector features three active areas, and the detection circuit compares the electric signals outputted from these areas to derive a digital waveform with a desired phase and duty cycle. This advancement allows for the correct decoding of digital signals into vector data by a digital circuit in subsequent stages. Additionally, it addresses the issue of signal level shifts caused by LED decay, overcoming defects found in prior art optomechanical encoders. In traditional encoders, a fixed voltage is used for comparison, which can lead to encoded signals being too strong or too weak due to variations in photodetector sensitivities and LED light intensities.
