  • Patent number: 8256906
    Abstract: A sliding cover structure and an electronic apparatus are disclosed. The sliding cover structure is used for covering a lens, and includes a base, a first cover, a second cover and a swing part. The first cover slides forwards and backwards on the base, and slides between an opening position that does not cover the lens and a closing position that covers the lens. The second cover moves upwards and downwards on the base. The swing part is pivoted with the base and has a first contact end and a second contact end. The pivoting position of the swing part and the base is located between the first contact end and the second contact end so that the swing part can perform a seesaw operation. The first contact end is located below the second cover so that the first contact end drives the second cover to move upwards.

  • Patent number: 8245304
    Abstract: Methods for detecting an attempt to perpetrate fraud on a user utilizing a client-supplied link and a client-supplied IP address from a user computer. The method ascertains a first autonomous system number (“first AS number”) from the client-supplied IP address and a second autonomous system number (“second AS number”) from the client-supplied link. If the first AS number and the second AS number are not AS group peers, a pharming attempt is detected. Alternatively or additionally, the method includes analyzing a content of a webpage that is accessed using the client-supplied IP address to ascertain an identity of an apparent owner of the webpage and ascertaining a third autonomous system number (“third AS number”) from the identity of the apparent owner of the webpage. If the first AS number and the third AS number are not AS group peers, a phishing attempt is detected.

  • Publication number: 20120102990
    Abstract: The present invention discloses an adsorption type refrigerator that automatically determines the switchover point. The adsorption type refrigerator includes a first vacuum chamber, a second vacuum chamber, a third vacuum chamber and a waterway structure. The waterway structure is connected to a first adsorption bed in the first vacuum chamber and a second adsorption bed in the second vacuum chamber. The waterway structure simultaneously conveys hot water into the first adsorption bed and cold water into the second adsorption bed, or simultaneously conveys cold water into the first adsorption bed and hot water into the second adsorption bed so as to allow the first and the second adsorption beds to conduct adsorption and desorption alternatively. This alternation creates pressure variation in the three vacuum chambers, which is then utilized to automatically determine the switchover point at which the refrigerator can provide and maintain a cold, stable environment.

  • Publication number: 20120085111
    Abstract: An adsorption type refrigerator with thermostatic control includes a first vacuum chamber, a second vacuum chamber, a third vacuum chamber, and a passage structure. The first vacuum chamber accommodates a first adsorption bed, a first condenser, and a first evaporator, and the second vacuum chamber accommodates a second adsorption bed, a second condenser, and a second evaporator. The third vacuum chamber contains a third evaporator. The passage structure guides hot water into the first adsorption bed and guides cold water into the second adsorption bed simultaneously, or guides the cold water into the first adsorption bed and guides the hot water into the second adsorption bed simultaneously. According to the ambient temperature or the temperature of ice water produced by the adsorption refrigerator, the cold water is stopped being guided into the first or the second adsorption bed timely, thereby ceasing the refrigeration temporarily and achieving the thermostatic control.

  • Publication number: 20120006049
    Abstract: A split solid adsorption cooling system is disclosed. The split solid adsorption cooling system includes a first adsorption unit, a second adsorption unit, and a shell-and-tube heat exchanger. The first and the second adsorption units are connected to each other via a first pipeline and a second pipeline of the shell-and-tube heat exchanger. While adsorption and desorption take place alternately in the first and the second adsorption units, the temperature of the first and the second pipelines is lowered, thereby decreasing the temperature of water flowing in the shell-and-tube heat exchanger. In addition, the manufacturing costs of the split solid adsorption cooling system can be lowered because the shell-and-tube heat exchanger need not be operated in a vacuum environment. Furthermore, as the shell-and-tube heat exchanger is separate from the first and the second adsorption units, the overall system volume is reduced.

  • Patent number: 8089912
    Abstract: A multicast communication method for relaying a multicast packet from a first member node to a plurality of second member nodes in a wireless network is provided, wherein the first member node and the second member nodes belong to a same group and can communicate with each other via a plurality of non-member nodes. In the multicast communication method, a number and distances of the second member nodes are recorded. The multicast packet is received from the first member node, and a waiting time is determined according to the number and the distances of the second member nodes. Whether the multicast packet is broadcasted by any other relay node is monitored during the waiting time. If the multicast packet is already broadcasted to all the second member nodes by other relay node, the multicast packet is not broadcasted; otherwise, the multicast packet is broadcasted after the waiting time elapses.

  • Publication number: 20110309822
    Abstract: A sensor system for receiving an input signal and applying a digital control signal to adjust an output sensitivity of a triggering signal within the sensor system. The input signal includes a bias DC and a fluctuation bias voltage. The sensor system includes a first voltage contact, a normalized voltage contact, a normalized circuit and a comparison circuit. The first voltage contact provides a first comparison voltage based on the digital control signal, wherein the first comparison voltage defines a standby voltage region. The normalized voltage contact provides a reference voltage based on the digital control signal, wherein the reference voltage is located within the standby voltage region. When the fluctuation bias voltage is located outside of the standby voltage region, the sensor system outputs a triggering signal so as to adjust the digital control signal.
