A system for controlling the operation of an in-vehicle multi-media system based on identifying operating conditions for the vehicle. An optical film is a laminate of an absorptive dichroic polarizing plate and a brightness enhancement film. A control document specifies tasks to be performed on the database structure. An imaging device may image the person at the determined frame rate. Furthermore, a radiation source of generating pulsed coherent radiation is described, comprising a laser pulse source for generating laser light pulses, a resonant cavity including a non-linear medium for generating high harmonic pulses by an interaction of the laser light pulses with the non-linear medium, wherein the non-linear medium is arranged in an environment of reduced pressure.
