Abstract:
The invention relates to a beam-forming array for projecting a divergent isotropic cloud of light points. Said array comprises a source (4) for emitting electromagnetic radiation, a receiving or connecting possibility for a power source (2), an electrical or electronic subassembly (5), and an optical unit (6) that is arranged in a housing (1) along with the radiation source (4). The radiation source (4) is a semiconductor diode laser or a light emitting diode (LED) while the optical unit (6) is composed of at least two superimposed and grid-shaped spectral films that are offset relative to each other or a diffractive optical element. The optical unit (6) limits the intensity of the emitted radiation and the distance of the light point beams relative to one another to a value that does not pose any risk to a human eye. The invention has the advantage of providing a miniature portable array that is inexpensive to produce and easy to handle for a large spectrum of indoor and outdoor uses in order to project any clouds of light points, particularly of real constellations.
Abstract:
The information on the constellations is given on a table (5) of constellations. The table (5) of constellations is illuminated by the light emitted from a light source, which consists of a bulb (7), and passed through a semi-transparent plate which is capable of diffusion-permeating the light from the light source therethrough. The table (5) of constellations is viewed through a magnifying lens (2). According to this invention, a bulb is used as the light source, and the information on the constellations is magnified by a lens. Therefore, a light, handy, miniaturized star chart device can be obtained.
Abstract:
The present invention relates to a utensil for learning constellation of four seasons whereon a constellation-plate with constellations of four seasons being arranged on Polaris's axis in circular shape is formed, and on it a confirming window is formed for learners such as infants or elementary school pupils to discern constellation easily according to seasons or months, which has superior effect to supply a utensil for learning constellation of four seasons consisting of a circular constellation-plate formed with a constellation part whereon constellation is expressed with Polaris as a center figure according to months in difference according to luminosity, a month index-band whereon 12-months is expressed in different colors according to seasons around said constellation part, a interpretation part whereon the way to find constellation according to seasons is written outside of month index-band, an index-plate formed with luminosity-expressing part inward of the month index-band on Polaris's axis, center of said circular constellation-plate, a confirming window formed comprised of a direction-expressing part which indicates the cardinal points (east, west, south and north) with Polaris as a datum and a transparently coated part on the index-plate and a joint material piercing Polaris on the circular constellation-plate through the transparently coated part of the confirming window and fixing it for rotation.
Abstract:
This apparatus, as it is arranged, allows one to observe in a simple and clear manner the stellar dome, in a way which was not possible with available clocks and apparatuses. No exact precision can or should be expected from this apparatus, as it is only meant to provide a visual background for a deeper insight into celestial mechanics. Exact data can be found in the already published tables of calculations.
Abstract:
In general, this disclosure describes techniques for providing a user of a computing device with the ability to view a realistic map of the sky based on information associated with the current location of the user. The information may be geographical information, orientation or directionality of the computing device, time and date, and zoom settings of the computing de vice. The computing device may use built- in capabilities (e.g., compass) and applications (e.g., maps and GPS) to determine the current location information. The computing device then uses the current location information to obtain celestial and topographical information. Using the celestial information, the computing device displays a map of the sky with the appropriate celestial bodies. Additionally, the computing device uses the topographical information to display a realistic rendering of the horizon, such that objects in the horizon may be displayed to render a realistic representation of the sky from the current location.

Abstract:
Dispositif pour simuler les mouvements apparents des planètes du système solaire, y compris ceux de la Lune et du Soleil. L'invention concerne un dispositif mécanique permettant à une personne profane en astronomie, de simuler dans l'espace à trois dimensions, les mouvements apparents des planètes du système solaire, et de définir leurs directions respectives à un instant donné et pour un lieu donné. C'est un planétarium simplifié qui ne nécessite pas de salle obscure, ni de personnel qualifié pour son fonctionnement. Le dispositif, porté par un socle (10) orientable selon le nord géographique du lieu d'observation, comprend pour l'essentiel un globe terrestre (1), une rosé des vent (2) et un zodiaque (3). Le dispositif est réglable de façon à ce que l'axe (5) portant le globe terrestre (1) et l'axe du dispositif soit parallèles à l'axe de rotation de la Terre, et que la rosé des vents (2) soit orientée selon les quatre points cardinaux du lieu d'observation. Ainsi, les fiches (24) représentant les planètes portées par le zodiaque (3), donnent, les directions des planètes telles qu'elles sont observables dans notre environnement céleste et permettent de simuler leur mouvement apparent respectif.
Abstract:
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.

Abstract:
The disclosed planisphere has three superimposed sheets (1, 2, 3). The lower sheets represent the two planispheres, the terrestrial (1) and the celestial (2) planispheres which are joined by a common rotation center (4) coinciding with the poles. The upper sheet (3), which is transparent as is (2), is excentric with respect to the prior ones since its rotation center is the pole of the ecliptic (5) situated in the parallel 66.5 of the celestial planisphere (2). Said sheet (3) is intended to mark out on the terrestrial planisphere (1) the areas which are illuminated (6) or which are not illuminated (7) by the sun (8). It has scientific-didactic applications since it simulates the night-day succession and the process of the seasons, while relating the positon of the stars and the height of the sun at midday with respect to places on earth. It also has industrial applications since it can be used as a watch face. Alternatives of said planisphere are obtained by suppressing any one of its three components or by providing said components as the surfaces of spherical caps.
