Physical-fitness test system using acceleration sensor
First Claim
1. A fitness measurement system, comprising:
- an acceleration sensor device having a 3-axis acceleration sensor and configured to measure 3-axis acceleration signals according to the movements of a test subject on whom the acceleration sensor device is attached and transmit the signals through RF communication, the acceleration sensor device including a belt insertion unit to support a belt;
an RF channel selector configured to arbitrarily set an identification number of the acceleration sensor device for the RF communication; and
an assessment and analysis unit configured to receive the 3-axis acceleration signals via a host gateway and detect a maximum acceleration from the 3-axis acceleration signals as an intensity of the exercise,wherein the belt insertion unit of the acceleration sensor device includesa groove formed across a middle part of a front side of the acceleration sensor device with a predetermined width and depth, anda belt holder including four strips disposed around four corners of the groove, respectively, wherein each of the four strips extends over the groove from the acceleration sensor device such that an outer surface of said each of the four strips is on the same plane with the front side of the acceleration sensor device, and an inner surface of said each of the four strips is apart from a surface of the groove with a gap through which a belt passes,wherein the RF channel selector is disposed on the surface of the groove, andwherein the belt is configured to attach the acceleration sensor device to the test subject.

Abstract
The present invention relates to a fitness testing system using an acceleration sensor, of which a mobile device containing an acceleration sensor is attached to the body of the test subject and the test subject is induced to perform an exercise according to the fitness test instructions provided through the fitness testing process installed in a personal computer during which the acceleration signals are measured through RF communication for an output of the fitness test and assessment results. For this purpose, the present invention embodies a fitness measurement system consisting of an acceleration sensor device with a 3-axis acceleration sensor that is attached to the test subject to detect the 3-axis acceleration signals produced according to the test subject'"'"'s movement and transmits the signals through RF communication; and an assessment and analysis unit that receives 3-axis acceleration signals from the acceleration sensor device through a host gateway and detects the maximum acceleration from the 3-axis acceleration signals received as the exercise intensity; wherein the execution processing unit of the assessment and analysis unit, in case the test items is “balance”, receives the x-axis acceleration signals, which are related to the left and right movement of the test subject, and z-axis acceleration signals, which are related to the forward and backward movement, via the host gateway and detects the trajectory according to the input x- and z-axis acceleration signals and the maximum acceleration value according to the forward, backward, left and right movements.
