Introduction

Chieh Changfan, an inventive mind based in Union City, California, has demonstrated remarkable creativity through his innovative contributions to technology. With a total of two patents to his name, Changfan is making strides in the fields of music technology and integrated circuit (IC) behavior analysis.

Latest Patents

Changfan's latest notable invention is the Melody-based music search. This groundbreaking music search engine allows users to locate desired songs within a database by comparing melodies. It operates through a dual architecture consisting of a client-end and a server-end. The client-end converts various input formats into a note sequence, which it then transmits to the server-end engine. The server-end efficiently compares the generated note sequence against the melodies stored in the database, ensuring that users can find songs based on melodic content rather than relying solely on titles or lyrics. Notably, this invention is designed to tolerate inaccurate inputs, making it accessible to less skilled users who may only be able to hum an approximate melody.

Another significant innovation by Changfan is the IC behavior analysis system. This system utilizes a debugger that generates a display based on instructions executed by a circuit simulator or verification tool. It also incorporates waveform data produced during the evaluation of these instructions. The debugger identifies a set of statement event symbols corresponding to various evaluations of circuit signals, presenting them in a manner that indicates the simulation times at which they occurred. This invention enhances the analysis of circuit behaviors, providing a comprehensive overview of signal values and their interdependencies throughout the simulation.
