A motion detector and method with low power consumption in an inertia sensor. The motion detector is selectively supplied with power for operation of the inertia sensor according to a power control signal. While the inertia sensor is supplied with power, three-dimensional analog signals are sampled, A/D converted, and outputted via a controller. A pulse width of the power control signal is determined by reflecting the sampling and A/D conversion period and reflecting the operation preparing period of the inertia sensor from the A/D converted value.

A noise removal method and system using a change in activity pattern, in which it is recognized that noise components exist in different frequency bands and different filters for removing noise are stored according to each activity pattern, thereby optimally removing the noise components. A method of removing noise by using a change in an activity pattern includes: recognizing an activity pattern of the subject using an activity sensor; sensing a first bio signal corresponding to the activity pattern from the subject using an electric potential sensor; recognizing a noise generation pattern according to the activity pattern by analyzing a noise component for each section of the first bio signal; selecting filter information for each section according to the noise generation pattern; storing the filter information selected for each section in association with the activity pattern; and removing noise from a second bio signal sensed from the subject by applying the stored filter information.

Provided is a physiological signal detection module which has a heating member and a multi-channel connector. The heating member maintains an electrode's contact with a user skin at a constant temperature, and the multi-channel connector module for electrical connection transmits the physiological signal to an external physiological signal detection apparatus. It is possible to prevent the skin from being directly contacted with the electrode in the cold state and have a less impact given by a change of the impedance due to a skin temperature based on the change of the season and external temperature, so that the stable physiological signal can be detected without distortion.
