Patent number: 10805139Abstract: A software-defined radio system for detecting packets is disclosed, including: a transmitting end configured for assigning a preamble and a postamble to a start position and an end position of a packet of a signal, respectively, before transmitting the signal; and a receiving end configured for detecting if a packet exists in the air or in a channel based on the preamble and the postamble, wherein the receiving end stores the signal in memory when detecting the preamble, and stops storing the signal in the memory and transmits the signal to a computing device when detecting the postamble. A packet detection method for a software-defined radio system is also provided.Type: GrantFiled: December 27, 2018Date of Patent: October 13, 2020Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Chih-Ying Chen, Ren-Jr Chen, Zan-Yu Chen, Chung-Lien Ho, Wen-Chiang Chen

Patent number: 8404511Abstract: Disclosed is a method for making a solar cell. In the method, there are provided first and second substrates each including first and second faces. There are provided first and second coating devices and a joining device. The first coating device is used to form a transparent electrode layer on the first face of the first substrate. The second coating device is used to form an absorbing layer on the first face of the second substrate. The second substrate is selenized by hot pressing. The joining device is used to join together the first and second substrates by joining the transparent electrode layer with the absorbing layer. The transparent electrode layer is joined with the absorbing layer by hot pressing. Thus, the solar cell is not made by coating one layer on another. Time for making the solar cell is reduced.Type: GrantFiled: December 21, 2010Date of Patent: March 26, 2013Assignee: Chung-Shan Institute of Science and Technology, Armaments, Bureau, Ministry of National DefenseInventors: Wen-Chueh Pan, Feng-Yu Tsai, Kong-Wei Cheng, Sheng-Ming Yeh, Hung-Chuan Hsu, Zan-Yu Chen
