摘要:
Featured is a portable planetarium device suitable for use in projecting clear bright images of stars, planets, and other celestial objects onto a curved viewing surface. The portable planetarium devices of the invention comprise a point light source generator (56), a light dispersing lens assembly (110), and an opaque enclosure (120) having transparent domains surrounding the light dispersing lens assembly. Also featured is a portable point light source comprising a light source (56) , a light collection element (58) and a light conducting conduit (80) suitable for use in providing high intensity light with a small cross-sectional area.
摘要:
A mobile terminal and a method of outputting celestial information using the terminal are disclosed. The mobile terminal includes a memory unit storing celestial information, an information acquiring unit acquiring terminal position information, terminal direction information including an azimuth and an altitude of the terminal, and time information, and an information processing unit searching the memory unit and outputting the celestial information corresponding to the position information, the direction information and the time information received from the information acquiring unit. It is possible to provide the celestial information of the sky located in a direction corresponding to the azimuth and the altitude of the terminal and to rapidly and conveniently find a celestial body a user wishes to observe.
摘要:
A method and portable terminal for searching for a constellation using the portable terminal are provided, in which position information, direction information, and time information of the portable terminal are extracted, a constellation corresponding to the extracted position information (170), direction information (180), and time information of the portable terminal is searched, a shape of the searched constellation is displayed (160), an enlargement/reduction function is performed while displaying the constellation shape, detailed information regarding the displayed constellation is displayed, position information, direction information, and time information of the portable terminal, and the shape of the constellation and the constellation information are stored, the position information, the direction information, and the time information of the portable terminal, and the shape of the constellation and the constellation information are transmitted to a receiver, and the constellation shape is set and displayed as a background image of the portable terminal.
摘要:
It's a device to find out and highlight the visible portion of sky, it consists of a mobile disc (1) that has got a representative map of stars of a celestial hemisphere, a fixed disc (2) overlapped to the map with a window (3) modelled to circumscribe a portion of correspondent shape and dimension to the portion of sky normally visible. A half temporised engine (8) is prearranged to make the fixed disc and the mobile one rotate of complete turn in 24 hours -4' so that the window (3) could permanently find out the portion of sky (4) currently visible. The fixed disc and the mobile disc can be entered according to the period of the year.

摘要:
A projection apparatus for generating a moving star field and a cloud-like effect comprises a means for generating a cloud-like effect using at least one non¬ coherent light source, a means for generating a moving star field using at least one coherent light source and a means for regulating and supplying electric power. The means for generating cloud-like effect using at least one non-coherent light source comprises at least one pair of condenser lenses and an interferential filter wheel rotated by a motor, disposed between at least one pair of condenser lenses. The means for generating the moving star field using a coherent light source comprises a grating wheel rotated by a motor and a diffractive optical element disposed between the at least one coherent light source and the grating wheel.
