It is an object of the present invention to provide an ink jet recording sheet which has high glossiness of the recording surface and is free from the bleeding of an image with time even under high temperature and humidity. The device comprises an upper thigh strap, a foot stirrup and a length of resilient elastic material adjustably secured therebetween and adjusted to maintain the user’s knee at a 90\xb0 angle during running. When the information is received, control channels are created, if they do not already exist. A performance function for the structural system is mathematically calculated based upon the measured drive point transfer functions and interface transfer functions.
