Provided is a base material having a conductor pattern formed thereon, which is obtained by forming, at a high productivity on a base material, a conductor pattern having a lower surface resistivity and a higher conductivity than in the related art. The systems further include a guide track configured to slidably receive the distal end of the tether, the guide track defining a motion path over which the platform slides freely in response to forces applied by a user’s foot while the gliding board is traversing a supporting surface. Several different methods can be used to produce the prosthesis, including a fiber winding and extraction technique, a melt extrusion technique, and a particle and fiber extraction technique using either a layered method or a continuous method. The electromagnet is disposed to generate first magnetic field that, via the permanent magnet, drives the rotatable shaft away from the closed position. A system of mutually separate units, whereof each unit operates with a CAN-signalling protocol, intercommunicable by means of radiocommunications operating with an identification system in which a key allocation between the units is based upon identities that are assigned by a module in the unit or a master system.
