Latest Patents

One of his latest patents is a method for detecting a SNP site on the SMA gene. This method includes several steps: performing a PCR to amplify a nucleic acid fragment containing a SNP site, conducting a dephosphorylation reaction, and executing an extension reaction using an extension primer. The SNP site is identified by extending the 3'-end of the extension primer with a single nucleotide complementary to the base of the SNP site. The process concludes with a purification reaction and measuring the molecular weight of the extended primer to determine the type of base at the SNP site.

Another significant patent is a power control apparatus and method for an optical drive. This invention estimates the temperature rising effect of a laser diode and performs partial open-loop power control. It achieves accurate write power control, which is crucial for high-speed, high-density optical disk recording mediums. The invention ensures that even with a slower response speed of the front photodiode, accurate write power control can still be maintained.
