A method of identifying injury to soft connective tissues in complicated body joints deploys use of motion x-ray images as the joint moves to identify suspected abnormal pathology followed by Dynamic Upright MRI images of the joint under conditions that express the abnormal pathology. The first layer includes a porous layer consisting of a carbide, nitride or carbonitride of at least one of the metals titanium, vanadium, zirconium, niobium, molybdenum, hafnium, tantalum or tungsten. A printing device is provided in the printing region to form an image on the sheet. An additionally recordable apparatus according to the present invention also includes means for updating the location information of the recorded area so that the recorded area located at the rearmost location in the user data area is always managed. The proposed CATT cells by elimination of high voltage requirements are scalable with technology and easily manufacturable using current processes technologies. Left and right steering may be performed by twisting the feet placed on the foot placement sections by the driver.
