A method for producing a structural andor safety-related motor vehicle component having at least one hot-formed and press-hardened part constructed from high-strength steel includes the steps of partially heat-treating a region of the motor vehicle component by heating the region to a heat-up temperature in a temperature range between 500\xb0 C. or higher, and the thermoplastic resin of the color toner receiving layer is a polyolefin copolymer, a temperature t at which the viscosity becomes 103 Pa\xb7s being from 90 to 120\xb0 C. A sensor array is arranged proximate the display screen to detect a touch on the display screen and to generate a set of touch position coordinates corresponding to a location of the touch. The earphone may include a fastener that removably mounts the nozzle to the housing so that the nozzle may be readily removed and cleaned or replaced. Such spacing reduces quantization induced over-design compared to conventional cell libraries which have a design delay spacing that is a decreasing function of cell drive strength. Methods for increasing lift and decreasing turbulence and drag on hydrofoils or vanes of the swim fins are also included.
