Title: Xian-Hong Shen: Innovator in Computer Technology
Introduction
Xian-Hong Shen is a notable inventor based in Shanghai, China. He has made significant contributions to the field of computer technology, particularly in testing methodologies for personal computers and floppy disk units. With a total of 3 patents to his name, Shen continues to push the boundaries of innovation in his field.
Latest Patents
One of Shen's latest patents is a PC interval timer test method. This method is designed to test the abnormality of the interval timer of a personal computer by calculating the difference between the periodic interrupt frequency of the PC's CMOS Real Time Clock (R.T.C.) and the interval timer interrupt frequency within the same time period. The results are then judged by comparing the value of the difference with the set maximum allowable value of error of the CMOS R.T.C.'s periodic interrupt frequency. The maximum frequency of the CMOS R.T.C. can reach up to 8192 Hz, allowing for a test error as minor as below 1/8192.
Another significant patent is a methodology for testing a high-capacity floppy disk unit installed in a notebook computer. This methodology involves giving corresponding commands to a multi-purpose connector for the disk unit to confirm proper connection. It also tests the operation capabilities of the disk unit for various types of diskettes, ensuring that the disk head can read, write, and seek on each track in various movement modes. Additionally, it verifies the disk unit's eject and format functions to ensure normal operation.
