Abstract: In an embodiment, a method includes: heating a byproduct transport ring of an extreme ultraviolet source, the byproduct transport ring disposed beneath vanes of the extreme ultraviolet source; after heating the byproduct transport ring for a first duration, heating the vanes; after heating the vanes, cooling the vanes; and after cooling the vanes for a second duration, cooling the byproduct transport ring.

Abstract: A roadside apparatus and a communication beam pointing direction adjusting method thereof are provided. A first radio frequency identification reader detects a first response signal of a wireless identification tag of a first mobile vehicle to obtain first signal strength information. The first signal strength information corresponds to strength of the first response signal. A first roadside unit determines a position of the first mobile vehicle according to the first signal strength information, and directs a communication beam of the first roadside unit to the first mobile vehicle.

Abstract: A data transmitting method, a data controlling module and a mobile device using the same are disclosed for transmitting data from the mobile device to a destination on an internet. The mobile device includes a first communication module and a second communication module. First, a first internet connection between the first communication module and the internet is established. Next, a second internet connection between the second communication module and the internet is established. Then, a local area connection between the first and second communication modules is established. The data to be transmitted are divided into several packets. A first part of the packets is transmitted from the first communication module to the destination through the first internet connection, and a second part of the packets is transmitted from the first communication module to the destination through the local area connection and the second internet connection.
