Abstract: A cooktop has a plurality of reflection-sensitive infrared sensors. A plurality of IR receiving elements is arranged along an operating line having a density such that an operator's finger placed on the operating line necessarily covers at least one of the IR receiving elements. A smaller number of IR transmitter diodes is arranged in correspondingly lower density next to the operating line. In the setting process, two effects are used on the operating line, specifically both the radiation of the optical transmitter reflected by the finger and also the radiation of the ambient light that is thrown into shadow by the finger. The resultant signal distribution on the optical receivers can be used for reliable evaluation of the finger's position in nearly all environmental conditions.

Abstract: A micromechanical component (10) in which lateral deformations, i.e., deformations of the component (10) parallel to its two main surfaces, are concentrated in a defined area of the component structure, making it possible to decouple lateral and vertical stresses in the component (10). The component structure includes at least one bellows-like structure (11) in which lateral deformations of the component (10) are concentrated.

Abstract: A puncture resistant footwear sole composite is disclosed with a plurality of layers of woven aramid yarn fabric combined with a matrix resin in an amount adequate to adhere adjacent fabric layers together but not so much that the composite is saturated by matrix resin.
