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: The invention is a machine used to test and sort small electronic components. The machine includes a feed station, a testing station and a sorting station. The components are carried between the different stations by a rotatable transport wheel that includes a number of peripherally-located and radially-aligned compartments.The testing station includes a top lead that is moved in a direction away from or toward the central axis of the wheel. The movement is controlled by a follower roller that is connected to the lead and that travels along a surface of a cam ring that is attached to the transport wheel. The testing station further includes a shielding strip that isolates the electronic component from surrounding fields during the testing operation.
