Apparatus for measuring activity
First Claim
1. An activity measuring device for recording the activity of a test subject, wherein the activity measuring device is securable to a buckle of a belt that is configured to be fitted to the body of the test subject such that the activity measuring device can be carried on the body of the test subject, the activity measuring device includes at least one acceleration sensor configured to detect acceleration in all three spatial directions at right angles to each other, and the activity measuring device is configured to distinguish between states of motion of lying, standing and sitting associated with the test subject for each spatial axis direction by determining a mean for each spatial axis direction from a corresponding series of measurements determined for each spatial axis direction, and by further comparing each mean with a corresponding assigned threshold value for each spatial direction.

Abstract
An activity measuring device (1) is used for recording the activity of a test subject, where the device (1) is attachable so as to be carried on the body of the test subject. According to the invention it is planned that the activity measuring device is located on a buckle (2) of a belt (3) which can be fitted to the body of the test subject, and that it has acceleration sensors (10, 10′) for detection of acceleration in all three spatial directions at right angles to each other. Furthermore, the activity measuring device (1) telemeters the recorded measurement data via a radio link to a central server (7), by virtue of the fact that the measurement data recorded by the activity measuring device (1) can be transmitted by means of a connecting cable (5) to a mobile telephone (4) via a device interface of the mobile telephone (4), which is arranged so as to be carried on the belt, and can be sent from there to the external server (7) via a radio link.

14. A method for recording an activity of a test subject, the method comprising:
-
continuously measuring, in three spatial directions that are at right angles to each other, body accelerations underlying the momentary physical activity of the test subject; and determining a current state of motion based upon the continuous measurements of the body accelerations of the test subject; wherein, in order to distinguish states of motion of walking and jogging associated with the test subject, a mean difference from a mean of measured values in a series of measurements is determined for each spatial axis direction, and the mean difference determined for each spatial axis direction is compared with a corresponding threshold value assigned to each spatial axis direction. - View Dependent Claims (15, 16, 17, 18)
