Abstract: A method for operating a vehicle electrical system, which includes an energy store. The energy store is assigned a sensor processing unit, and an electronic load distributor. At least one measured variable is detected using the sensor processing unit, and a parameter of the energy store is calculated taking the at least one measured variable into account. A plausibility check of the at least one measured variable is carried out, and a plausibility check of the calculation is carried out, for which purpose the electronic load distributor is used.

Abstract: A method for monitoring a cable harness. In the method, at least one value of at least one electrical variable in the cable harness is acquired and at least one signal, which represents this at least one value, is transmitted to at least one evaluator. A number of containers, which in turn represent a value range for the allocated electrical variable in each case, is allocated to each evaluator. The at least one signal is evaluated in such a way that the acquired values are allocated to the containers while taking the respective value range into account. The values allocated to the container are counted in each container. If a threshold value allocated to the container is exceeded, an action is triggered.

Abstract: A method for configuring a vehicle electrical system of a motor vehicle, at least one consumer being provided in the vehicle electrical system. Within the scope of the configuration of the vehicle electrical system, at least one of the at least one consumer is assigned an electrical module, which in turn is selected from a group of modules. A first consumer criterion, which refers to a supply requirement of the at least one consumer, and a second consumer criterion, which refers to a degree of feedback of the at least one consumer, are taken into consideration in the selection of the electrical module.

Abstract: An optically pumped semiconductor disk laser including a pump light source, at least one semiconductor body (2), which semiconductor body (2) has at least one window region (8), an active region (7) and a reflection device (P), which reflection device has at least one first P-reflection element (P1) for the pump wavelength. The first P-reflection element (P1) is embodied and arranged such that pump light emerging from the pump light source (3) can be guided for at least two passes through the active region (7). A total thickness of the active region (7) and of the window region (8) in the direction of an optical axis of the semiconductor disk laser is less than three times the laser wavelength in the active region (7).
