Abstract: The invention relates to a heatable touch sensor and a steering wheel. It has an optical waveguide which is connected to an electrical heat conductor. The optical waveguide changes its transmission behavior, which is determined, with a change in position or bending. The heat conductor is a resistance heater which emits heat by applying an electrical voltage and by the associated current flow. The touch sensor operates by means of optical interferometry, which enables a very high sensing accuracy.

Abstract: In a container (3) for a plurality of single doses of a fluid active substance, in which the single doses are separately packaged in a gas-tight manner and can be released separately, the container (3) comprises a substantially flat carrier film, which carries a plurality of gas-tight cavities (33) including discharge channels (32) oriented to the periphery of the carrier film and opening at a distance from the periphery of the carrier film. Incisions (30) departing from the periphery and ending transversely to the discharge channels (32) at a distance from the same are provided, which discharge channels (32) are releasable by tearing and separating transversely to the axis of the discharge channels (32) upon bending and pulling on the tabs formed by the incisions (30).
