Recently, a digital buttons of hand-held equipment has been invented. And it has achieved the national patent of China (patent No: 00216903.7). This invention will probably produce a great impact in the digital buttons' operation pattern of hand-held equipment such as mobile-phone, wireless phones etc. I hope to have this opportunity to cooperate with related company as to produce things correlated with this patent.
