|---|
| 434284000 | Astronomy | 6 |
| 20080261190 | APPARATUS AND RELATED METHODS FOR THE CONTROLLED ILLUMINATION OF A CONVEX SURFACE - Illumination provided to the interior of a convex surface can be controlled using a plurality of internal barriers separating light sources such as light emitting diodes. Such controlled illumination can simulate phases of the moon using logic which can be limited to yes or no Boolean decisions, thereby minimizing the complexity of required input. | 10-23-2008 |
| 20100124735 | HAND-HELD PERSONAL PLANETARIUM - Method and apparatus are provided for a hand-held planetarium which displays a sky pattern comprising graphical representations of one or more celestial objects. A sensing system comprising one or more sensors provides information about an orientation of the device. A controller receives the information about the orientation of the device from the sensing system and determines therefrom an altitude angle of a pointing axis and an azimuthal angle of the pointing axis. The controller accesses a database of celestial objects and determines, from within the database, one or more selected celestial objects for display based at least in part on a measure of proximity of the celestial objects to the pointing axis. Graphical representations of the one or more selected celestial objects are displayed on a display screen. The planetarium may switch between a normal orientation mode and a downward facing orientation mode. | 05-20-2010 |
| 20100291525 | Moon Gazers' Wheel Chart - An educational field chart used for observing the Moon. The two-piece chart has an indicator wheel joined with a background chart that depicts the Sun, Earth and the Moon in orbit. The pieces rotate to locate a moon phase illustration that matches the Moon in the sky. Once set, a user can automatically determine facts and aspects about the Moon during this phase. Information aligns on both pieces to tell the following about the Moon: a) the moon phase name, b) the position of the Moon in orbit going around Earth, c) the rise & set time of the phase, and when it is visible in the sky, and d) the approximate day of the phase in the lunar month. The illustrations on the chart also visually correlate the relationship of the Sun, Earth and Moon during each moon phase. | 11-18-2010 |

| 20120148995 | APPARATUS AND RELATED METHODS FOR THE CONTROLLED ILLUMINATION OF A CONVEX SURFACE - Illumination provided to the interior of a convex surface can be controlled using a plurality of internal barriers separating light sources such as light emitting diodes. Such controlled illumination can simulate phases of the moon using logic which can be limited to yes or no Boolean decisions, thereby minimizing the complexity of required input. | 06-14-2012 |

| 20180025668 | STARRY SKY REPRODUCING SHEET AND DEVICE | 01-25-2018 |
| 434287000 | Celestial globe | 1 |
| 20150104775 | CELESTIAL GLOBE - A celestial globe model includes several petal-shaped sheets and two circular sheets fabricated from transparent and flexible material. Each petal-shaped sheet has two opposite end portions respectively defining a notch and two long curved edges interconnected with corresponding long curved edges of an adjacent petal-shaped sheet to form a sphere like body with a circular opening confined by the notches. The inner surface of the sphere like body is formed with the first celestial coordinate pattern. The circular sheets are connected sealing to the peripheries of the notches of the petal-shaped sheets to form the sphere like body once inflated. Each circular sheet has an inner surface formed with the second celestial coordinate pattern. An inflate valve is mounted on one of the circular sheets for inflating and deflating the sphere-like body. | 04-16-2015 |
