Abstract: A method is disclosed for operating a cooling system with a heater and a coolant pump for an internal combustion engine. The cooling system is switched into a predetermined operating mode as a function of a heater request and a temperature.

Abstract: The present disclosure relates to a method for determining an actuating value for a coolant pump or a control valve of a cooling system for an infernal combustion engine of a motor vehicle. In particular, a pre-control value for ascertaining the actuating value is determined in a first determination mode based on a prescribed first allocation as a function of an output variable of the infernal combustion engine and a temperature difference of a heat exchanger of the cooling system.

Abstract: A method is disclosed for operating a cooling system with a coolant pump for an internal combustion engine. The coolant pump is operated for a preset period of time after a starting of the internal combustion engine. The cooling system is switched over into a first warming-up operating mode, in which the coolant pump is not operated, in the case that a first warming-up condition is fulfilled.

Abstract: Seed pulse generators for fiber amplifier systems include a seed pump controller coupled to a seed pump laser diode. A photodetector is situated to detect seed pulse generation, and is coupled to the seed pump controller so that seed pumping is decreased upon pulse detection. For a laser diode pump source, a pump current can be pulsed to produce a seed pulse and then decreased to a bias level such as a DC bias current that is less than a pump laser threshold current. Single seed pulses can be generated with reduced pulse jitter.

Abstract: A program verification mechanism includes an external call reference verification mechanism that verifies external call references in a computer program. The external call reference verification mechanism checks the computer program after the computer program has been loaded by a loader/linker. The loader/linker stores a list of trusted entry points that specifies a trusted entry point for each external call reference, along with a list of allowable caller code for each trusted entry point. The external call reference verification mechanism determines the entry point for each instruction that is an external call reference, determines whether the entry point is listed as the trusted entry point for the external call reference, and whether the external call reference instruction is in the list of allowable caller code for the trusted entry point. If so, the computer program is verified. If not, verification of the computer program fails.
