An image obtained when a rare or valuable thing is found is shared between users each wearing an image display apparatus on the head or face.When a man finds a rare or valuable thing, the man feels like telling it to his / her surroundings. For example, when the man finds a planet such as Venus or shooting stars in the night sky, fish or a fresh water crab in a pond or a river, a bird, a cicada, a unicorn beetle, or the like on a tall tree in the woods, the man feels like saying “Look there!” An image display apparatus 100 releases a captured image in a line-of-sight direction of the user to share a user's precious experience with other users.

The invention relates to an anti-mosquito bat cave comprising a shaft enclosure built on a vertical shaft in a little hill by using stones, an upper shaft wall, a lower shaft wall and a cave, wherein the upper shaft wall, the lower shaft wall and the cave are arranged in the vertical shaft; the shaft enclosure exposes out of the ground, is in a horn shape with a wide top and a narrow bottom, and can prevent snakes and rats from climbing therein; the upper surface of the shaft enclosure is provided with an opening, and the lower surface is provided with the vertical shaft; the upper shaft wall of the vertical shaft is in a horn shape with a narrow top and a wide bottom, and the abdomen part of the vertical shaft is provided with a plurality of caves distributed along the horizontal direction; the caves are provided with floors, side walls, bottom walls and top walls, and waterproof asphaltum layers are coated on the top walls of the caves; the connection position of the upper shaft wall and the lower shaft wall is provided with a water drainage pipe with grates, which can prevent underground water from immersing the caves; and the lower wall is vertically built and can receive water capable of adjusting the temperature and humidity. In the daytime, bats stick to the top walls by using double feet in the dark caves to evade wind and rain as well as the intrusion of the snakes and rats; and in the nighttime, the bats drop into half air by unclenching the feet and fly into the night sky through the cave opening and the shaft opening to capture flying mosquitoes. The anti-mosquito bat cave is arranged in gardens of residential areas or tourist areas, can eliminate mosquitoes, and has no electricity consumption and no pollution.

The present invention offers an improvement to existing canting, slope error, and / or pointing measurement approaches, by using one or more cameras to observe the reflections of points of light in the firmament, such as the reflections of stars and / or planets as visible within the night sky in the heliostat facets. An illustrative heliostat measurement system comprises a plurality of heliostats, and at least one camera that observes at least one heliostat. The heliostats reflect an image of the firmament that can be observed by the at least one camera. The system further comprises (i) at least one captured image of the firmament reflected from at least one of the heliostats; and (ii) a computer comprising programming that determines a heliostat imperfection from the captured image, wherein the heliostat imperfection is selected from at least one of a slope error, a canting error, and a pointing error.

The invention discloses a stationary transparent vacuum ger tent. The stationary transparent vacuum ger tent comprises a main tent and an attached tent, wherein the main tent comprises an annular wall and a taper head cover; the attached tent is a cylindrical body, the taper head cover is arranged at the top of the annular wall, the attached tent is arranged on the side of the annular wall, the three parts are made of the double-layer organic glass or double-layer glass, and a vacuum layer is formed between each of the double-layer organic glass or double-layer glass; the connecting parts among the annular wall, the taper head cover and attached tent are connected and sealed via the colloid, liquid holes are respectively formed in the annular wall and the bottom of the attached tent, and a liquid pipe is connected with the liquid holes. The stationary transparent vacuum ger tent adopts the vacuum design, the heat preservation performance of the tent is relatively good in winter, the tent is non-transparent in summer for reflecting the sunshine which cannot directly irradiate the tent, and the tent transparent degree can be adjusted at any moment, the tent can be adjusted into the transparent state for seeing sunrise / fall; the lower part of the tent for 2 / 3 can be adjusted in the non-transparent state for seeing night sky while the upper part of the tent for 1 / 3 can be adjusted in the transparent state for meeting the private space requirement for people.

The invention provides a rotary festoon lamp acoustooptical device on a model airplane, belonging to a sport entertainment model aircraft. Color light-emitting tubes and acoustic equipment are arranged on the positions which are seen easily on the body and wings of the model aircraft and propellers, therefore, when in flight, favorite songs and analog sounds can be heard in the air, and when in night flight, the light-emitting tubes arranged on the propellers rotate to form color light rings with different sizes, thus adding a beautiful and splendid view for night sky. In addition, operators can judge the flight direction and high-low orientation of the model airplane through the fixed festoon lamps and rotary festoon lamps on the model airplane in night flight. The rotary festoon lamp acoustooptical device on the model airplane has the advantages of enabling the model airplane to adapt to the flight environments in day and at night, greatly attracting and increasing the interests of people in the model airplane, and playing a promoting role in wide development of model airplane activities and promotion and popularization of model airplane equipment.
