Title: Innovations of Chao N Liu

Introduction

Chao N Liu is a notable inventor based in Yorktown Heights, NY (US). He has made significant contributions to the field of technology, holding a total of 5 patents. His work primarily focuses on data archiving methods and pressure sensing devices.

Latest Patents

One of Liu's latest patents is titled "Scan-free archiving." This method involves archiving data in a storage server using a runtime monitoring system. The process includes providing multiple data files and creating access logs in a specified format. The method examines at least one access log to determine which files should be archived based on their access history. If a file has not been accessed for a specified period, an archive procedure is initiated. Additionally, the method checks for duplicate entries in the access log before archiving the file.

Another significant patent is the "Pressure sensing device and transducer arrangement." This device serves as a simple pressure sensor, particularly useful in Signature Verification Systems. It features a unique mounting structure for the pressure sensing stylus, supported by flexible means mounted on a rigid base. The design ensures that the deflections of the support members and the output of the pressure sensing element remain independent of the angle of pressure applied to the stylus. In this special purpose embodiment, the stylus functions as a pen, and the device includes two orthogonally disposed accelerometers to sense the pen's movements during signature writing.
