A clip module and a heat dissipation device having the same are disclosed, wherein the heat dissipation device is suitable to dissipate the heat for a heat source on a circuit board. The method and system use a mathematical rotation between a first coordinate system and a second coordinate system in order to calibrate a camera with a map of an area. Two inputs of the communication module receive the connection with the pulse meter. At least a part of the modulation electrode includes a base 2a, 3a formed on the substrate 5 and a projection part 2b, 3b having a width narrower than that of the base. Accordingly, command collision can be avoided, and as a result, communication efficiency and communication stability can be improved. In the method, the serving BS broadcasts a neighbor advertisement message including the BS ID of at least one neighbor BS about which the serving BS wants to acquire information, and the BS ID of the at least one neighbor BS.
