An improved brassiere of the type having a pair of cups, torso bands, and shoulder strap, and apparatus for connecting the pair of shoulder straps. In the chuck, fluid paths are formed. For example, when there is a fault, a transparent heater is operated to heat a liquid crystal layer to set a transparent-scattering changing element to a transparent state and forcibly set the display device to a narrow vision display. The first solvent and the second solvent have different evaporation temperatures. Under a condition of outputting high current, the present invention can greatly reduce power-consumption of rectifying and enhance efficiency. The method can include performing a non-difference comparison between a first received sound and a second received sound, determining if speech exists based on the comparison, and transmitting or providing a decision that the speech is present to at least one among the device, a cell phone, a media player, or a portable computing device.
