A gliding board including a longitudinal beam having a laminated structure that includes a bottom surface layer possibly edged with lateral running edges, reinforcing layers, a decorating layer, and a central core, the board being equipped with a data exchange label. The apparatus includes a first probe having a loop structure that supports electrodes or other operative elements against the body tissue and a second probe with an expandable push structure that may be used to urge the loop structure against body tissue. The base plate is formed with a generally elliptical through-hole, while the fastening plate is provided with a locking protrusion to be fitted into the through-hole of the base plate when the base plate and the fastening plate are superposed on each other. Power drive structure is mounted with respect to the main frame structure and is constructed and arranged to drive the wheels and the track simultaneously so as to move the vehicle along the ground. The circuit unit has several first positioning portions and the predetermined element has several second positioning portions. Drives are provided to move the base plate in longitudinal direction and to rotate the turntable.
