A socket structure with a remote control switch comprises a control switch and a power-supplying seat. In the case of transmitting data in which a characteristic curve is very important to a remote site, a predetermined number of the above data are collected at a transmitting site 100 so as to dummy-picture the data. The invention is further a set of such bands, each with its own design, placed around the outside of individual containers to enable users to distinguish their beverage from others that are in the same type of container. Either the travels or the speeds are redundantly detected and the accelerations singularly detected, or alternatively the accelerations are redundantly detected and the travels or the speeds are singularly detected, or preferably the travels or the speeds and the accelerations are redundantly detected.
