Abstract: An LED curtain includes a plurality of transparent hollow tubes parallelly connected side by side to form an integral unit and serve as a basic curtain body; a plurality of light-emitting strings, each of which includes a plurality of serially connected light-emitting diodes (LEDs) sequentially disposed in each of the hollow tubes; and a light controller internally provided with a circuit board, from which a plurality of signal lines is extended to separately connect to the light-emitting strings. Multiple pieces of the LED curtain can be hung to a track via a plurality of hooks provided at upper ends of the light-emitting strings. By operating the light controller to control the LEDs, different patterns or animations can be displayed on the curtain via the light-emitting strings, and different brightness of LEDs can be regulated to illuminate a room or create a special atmosphere.

Abstract: A game doll authentication device includes a doll; a Bluetooth wireless transmission system based wireless sensing device implanted in the doll; a plurality of chip sensing sockets and memory chips implanted in the doll at different positions; and game-related items associated with the doll and having memory chips implanted therein. The memory chips stores authentication information in connection with an electronic game and the wireless sensing device is able to read the stored authentication information and transmits the same to a computer for a game player to complete login procedure on the computer. Any level-up data in connection with the game player can be transmitted from the computer via the wireless sensing device to the doll for storing in the memory chips. With these arrangements, the game player can play the electronic game with increased online security and virtual treasures in the electronic game can be given a real form.
