  • Publication number: 20100073767
    Abstract: A transmission type screen for stereoscopic images having a transmission layer includes an incident surface having a gloss surface, a transmission layer having a refractive index less than 1.55, a transmissivity more than 60%, and an imaging surface having surface particle sizes of 40 to 400 mesh that avoids a hot spot. The imaging surface is formed on the final surface through which images are transmitted, so that the components operate in an organic fashion with respect to each other. The polarization degree of stereoscopic images is maximized thereby increasing the three-dimensional effect and the transmissivity, and enables viewers to view images clearly several times better than with a conventional screen.

  • Publication number: 20100053105
    Abstract: A song writing method and apparatus using a touch screen in a mobile terminal are disclosed. The song writing method includes: displaying, upon activation of a song writing mode, an onscreen musical keyboard of an octave on the touch screen; identifying, when a key of the onscreen musical keyboard is touched, a musical note mapped to the touched key through computation of coordinates of the touched key; creating musical interval data on the basis of the identified note and the current octave level; and converting the musical interval data into sound data recognizable by the mobile terminal and outputting the sound data. Hence, various types of songs can be conveniently composed through the song writing method employing the onscreen musical keyboard. The applicability of the mobile terminal can be extended through a function that can mix a written song with contents generated through various musical instruments.

  • Publication number: 20100018817
    Abstract: A pneumatic active engine mount has a middle fluid chamber and a pneumatic chamber inside an orifice module using a pneumatic plate. The orifice module divides an inner space in which working fluid is encapsulated into an upper fluid chamber and a lower fluid chamber. A change in the air pressure of the pneumatic chamber causes a change in the pressure of the middle chamber to thereby introduce a flow of working fluid between the upper fluid chamber and the middle fluid chamber. Various frequencies of vibration in an engine of a vehicle are reduced, and in particular, engine vibration in a middle-to-idling range is actively reduced.
