METHOD FOR FILTERING WEB PAGE CONTENT AND NETWORK EQUIPMENT WITH WEB PAGE CONTENT FILTERING FUNCTION
Publication number: 20130067591Abstract: A method for filtering web page content is disclosed in this invention. In the method, a web page request to obtain a web page from a web server is received from a client through a network equipment after the client builds a connection with the web server. The network equipment transmits the web page request to a cloud server for determining if the web page needs to be blocked according to the web page request. A first disconnection request and a second disconnection request is generated according to the web page request if it is determined that the web page needs to be blocked. The first disconnection request is transmitted to the client and the second disconnection request is transmitted to the web server through the network equipment. Subsequently, the connection between the client and the web server is disconnected.Type: ApplicationFiled: September 29, 2011Publication date: March 14, 2013Applicants: PROSCEND COMMUNICATIONS INC., NATIONAL CENTRAL UNIVERSITYInventors: Li-Der CHOU, Hua-Rong CHU, Hsu-Chuan WEI, Neng-Hsing CHEN -
Patent number: 8321298Abstract: A real-time, localized and mobile matching method for proxy purchase includes the following steps: position information of several default purchasing agents is received. At least one purchase request is received from at least one client. The purchase request includes information of at least one product to be purchased and location of at least one vendor of the product to be purchased. Candidate purchasing agents, position information of which corresponds to the location of the vendor of the product to be purchased, are filtered from the default purchasing agents. The information of the candidate purchasing agents is transmitted to the client, such that a selection signal, which includes information of a selected purchasing agent selected from the candidate purchasing agents, is received from the client. The purchase request is transmitted to the selected purchasing agent through a wireless communication network.Type: GrantFiled: April 26, 2010Date of Patent: November 27, 2012Assignee: National Central UniversityInventors: Li-Der Chou, Yu-Hong Lin

Publication number: 20100185501Abstract: A mobile advertising device includes an e-paper, a display control unit, a wireless communication unit and a processing unit. The display control unit controls the e-paper. The positioning unit receives a positioning signal and calculates the present location of the mobile advertising device according to the positioning signal. The wireless communication unit builds a connection with a server through wireless communication and transmits the present location of the mobile advertising device to the server. The processing unit includes an advertising module to obtain at least one advertisement of at least one store corresponding to the present location of the mobile advertising device from the server through the wireless communication unit. Then, the advertising module displays the advertisement of the store on the e-paper through the display control unit.Type: ApplicationFiled: May 27, 2009Publication date: July 22, 2010Applicant: National Central UniversityInventors: Li-Der Chou, Wei-Sheng Chen, Yao-Tsung Yang

Patent number: 7664500Abstract: A network service control method detects whether a mobile node communicating with a corresponding node is trending to a second local area network from a first local area network and forks and transmits a user agent and a server agent to a proxy when the mobile node is trending to the second local area network. After that, the user agent registers onto the proxy according to a result obtained by the handshaking. Finally, when the mobile node moves into the second local area network, the mobile node communicates with the user agent for obtaining a connection tunnel reserved by the user agent to communicate with the corresponding node.Type: GrantFiled: January 27, 2006Date of Patent: February 16, 2010Assignee: Industrial Technology Research InstituteInventors: Li-Der Chou, Wei-Cheng Lai, Chen-Hau Lin
