20090237626 | PROJECTION OPTICAL SYSTEM AND LIGHT AMOUNT ADJUSTING COMPONENT USED IN THE SAME - A light amount adjusting component adapted a projection optical system is provided. The light amount adjusting component has a light incident surface upon which a light beam impinges, and the light incident surface is provided with a surface structure for irregularly dispersing the light beam. A slot that permits the light beam to pass therethrough and enter a light-receiving element is formed on the light amount adjusting component, and a width of the slot changes along an extension direction of the slot to allow control of the amount of the light beam entering the light-receiving element when the light amount adjusting component moves or rotates. | 09-24-2009 |

20120225681 | Method of Providing a Vehicle with Communication Service and Micro Base Station Applied to Vehicle - A method of providing services to a vehicle and a micro base station applicable to a vehicle. The micro base station is disposed on the vehicle and is connected to the core network and the mobile communication device, either with different or the same wireless communication techniques. The mobile communication device is then enabled to communicate with the core network according to a connection relation between the first wireless communication technique and the core network. With the micro base station and the method of providing services to the vehicle, chances of performing a handshaking process between the communication device installed on the vehicle and the core network base station are greatly reduced, and the stability of signals received by the mobile communication device is highly improved. Therefore, the communication quality between the mobile communication device and the core network is enhanced. | 09-06-2012 |
