Abstract: A method and an apparatus for setting a sports mode are provided. Two metal endpoints on an outer surface of an intelligent device are respectively used as an output end and a receive end of signals. A signal sent by the output end is compared with a signal received by the receive end to determine whether the intelligent device currently meets a preset condition. First sports characteristic data detected by a sports sensing apparatus is obtained to determine whether the first sports characteristic data matches preset sports characteristic data corresponding to a swimming mode. When two determining results are both “yes”, it can be determined that the intelligent device meets a setting condition of the swimming mode.

Abstract: A signal measurement method and a signal measurement apparatus (1000) are provided. A mode selection switch (11) may be used to enable a multi-lead measurement mode, to obtain signals of a plurality of leads and a status of a user. When quality of the signals of the plurality of leads is good or the user is in a static state, extracted features of the signals of the plurality of leads are output. When the signals of the plurality of leads are poor and the user is in a moving state, the mode selection switch (11) is used to switch to a single-lead mode with right leg drive, to obtain a signal of a single lead. A common-mode signal is eliminated from the signal of the single lead by using a negative feedback of a right leg drive electrode, and a feature of the signal of the single lead is output.
