  • Publication number: 20130067591
    Abstract: 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.

  • Patent number: 8262444
    Abstract: An electronic device includes a housing, and an active fan and an airflow reversal prevention assembly installed in the housing. The assembly includes a first grid plate defining a plurality of vents, a second grid plate abutting against the first grid plate, a passive fan, and an elastic member. The second grid plate defines a plurality of vents being selectively aligned with the vents of the first grid plate. The passive fan is driven by air from the active fan to rotate, thereby driving the second grid plate to slide relative to the first grid plate. Thus the vents of the second grid plate are aligned with the corresponding vents of the first grid plate. The elastic member is capable of urging the second grid plate to slide to return, whereby the vents of the second grid plate are out of alignment with the vents of the first grid plate.
