  • Publication number: 20070018959
    Abstract: A computer mouse interface system has a mouse section which includes a tactile feedback section arranged to stimulate a finger of a user through a plurality of pins, so that the user can feel the nature of a virtual object displayed on a computer screen. The system further has a thermal feedback section arranged on a side of the mouse section to provide thermal information of the virtual object to the finger of the user. The thermal feedback section comprises a thermoelement for discharging or absorbing heat in response to a control signal according to a temperature variation when a users finger is contact with the virtual object, a cover brought into contact with a surface of the thermoelement to receive heat from the thermoelement, and a cooler brought into contact with another surface of the thermoelement to absorb heat discharged from the thermoelement.

  • Publication number: 20060280678
    Abstract: Disclosed are an apparatus for preparing hydrogen and carbon monoxide (hereinafter, referred to as “synthesis gas”) from methane and an oxygen containing compound using an atmospheric pressure barrier discharge reaction and a method for preparing the synthesis gas using the same. According to the invention, when the synthesis gas is prepared from the methane and the oxygen containing compound using the barrier discharge plasma at the low temperature, it is possible to obtain the same performance as the case using a high temperature catalyst reaction more economically at a time. In particular, according to the invention, it is possible to save the energy by about 35%, compared to the case using the prior heating only.

  • Publication number: 20060056415
    Abstract: A method and apparatus for detailed accounting of packet data are disclosed. According to one embodiment of the present invention, on receiving a duplicated HTTP request from a packet duplication apparatus, a billing apparatus extracts an access address to generate a first hash value. Then, on receiving a converted HTTP response from the packet duplication apparatus, the billing apparatus extracts a second hash value from the duplicated HTTP response to compare with the first hash value. If the first hash value and the second hash value are the same, the billing apparatus sets the HTTP REQUEST and the converted HTTP response as a transaction to generate billing data. Thus, the billing apparatus can generate accurate billing data.
