摘要:
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.

An apparatus, medium, and method for calculating calorie consumption of a user performing physical activity. More particularly, an apparatus, medium, and method for calculating calorie consumption can determine a user's activity pattern via an acceleration sensor attached to the user, and calculate the user's calorie consumption by using a predetermined slope value according to the activity pattern and a heart rate measured via a heart rate sensor attached to the user. Accordingly it is possible to calculate calorie consumption of a user performing physical activity by considering the user's heart rate and the type of physical activity and accurately calculate the calorie consumption by using both an acceleration sensor and a heart rate sensor.

A circuit and method for compensating for an electrode motion artifact in which the electrode motion artifact is generated because impedance between a subject and a measuring electrode changes during measurement of the subject's biosignal, and the electrode motion artifact can be differentially measured and an electrocardiogram signal can be compensated by introducing a predetermined voltage or an electric current to the subject. A circuit and method for compensating electrode motion artifact, which can differentially measure the difference information between impedance components by introducing a predetermined voltage or electric current to a subject, in association with the electrode motion artifact. In this instance, the impedance component is a component of electrode motion artifact and the electrode motion artifact is generated when measuring a biosignal.
