Abstract: A wireless network in which wireless terminals associate with particular access points maintains information about the positions and associations of the terminals and calculates loads on access points. To provide increased bandwidth at a heavily loaded access point, terminals associated with adjacent access points are handed over to more distant access points, so that the adjacent access points become less active and generate less interference. The hand-over is initiated and carried out by the access points concerned, rather than by the terminal that is handed off. Loads can accordingly be balanced promptly and interference can be reduced.

The low temperature FBG-mounting structure includes an FBG module and a thermo module. The temperature of the FBG in the latter FBG module may be made lower than the environmental temperature by supplying heat from the latter thermo module to the heat-conducting portion. The FBG-mounting structures are provided in parallel on the inner bottom surface of the heat-conducting portion, part of the housing.
Abstract: An inflatable pneumatic bag includes two outer films up-down stacked, and two inner films located between them. By thermal-sealing means, an interval line is formed between upsides and downsides of the two inner films, while a pneumatic passage is formed between the upsides of the two inner films and the interval line. Air tubes are formed between downsides of the two outer films and the interval line, while the two inner films are bonded at the interval line to form air ingress for connecting through the pneumatic passage and the air tube. After thermal-sealing upsides of the two outer films and the interval line, a buffer space is formed between the outer films and the two films. When the air of the air tube is leaking to the buffer space, the air of the buffer space will press the inner films to seal the pneumatic passage and prevent from leaking.
