An LED light unit, in particular for a passenger transport vehicle, such as an aircraft, a road vehicle, a ship or a rail car, is disclosed that has at least one LED and is configured to be used with a high intensity discharge lamp power supply that is adapted to monitor its output behavior. In an aspect, the housing is formed on the side of a board insertion opening with a recessed portion for conducting the board. The organic electroluminescent device display includes a substrate, an organic electroluminescent device disposed on the substrate, a sealing cap for sealing the organic electroluminescent device, and a getter disposed inside the sealing cap, the getter comprising a graphene layer. A real time dynamic analysis of a cardiac rhythm is applied to adjust and integrate CPR prompting of a medical device. The microprocessor includes a configurable clock and a routine structured to reduce current consumption from the power supply through modulation of the configurable clock. The audiovideo information is streamed at a constant rate from a source having an output buffer and so as to prevent overflowing of the output buffer, the streamed audiovideo information is received at a constant rate for storage into an input buffer, the streamed audiovideo information is for recording thereof onto the compact disc recorder so as to prevent underflowing of the input buffer.
