The invention relates to rubber mixtures, comprising: at least one rubber, at least one oxidic filler and at least one alkylpolyethersilane of the general formula Si\u2014RI-Hal. The lightly-doped amorphous silicon layer rests on a planar surface at least above and in the vicinity of the lower electrode. The evaluation and control unit have at least one interface, which receives signals from the at least one predictive sensor unit, and an arithmetic unit which is coupled to the at least one interface and analyses signals from the at least one predictive sensor unit for detecting an object in a lateral monitoring region and for determining information about the detected object. A composition with an agent active for relieving symptoms of a disease is also included. The second LGP guides a path of the infrared lights of the detected touch inputted in accordance with a touch operation. The resultant bag has the slider seated in the cut-out where it is readily visible to a consumer.
