摘要:
The present invention relates to a process and plant for storage and recovery of energy using a combined plant that comprises a gas treatment unit and an energy generation unit, wherein in a first operating mode, a low-temperature gas liquefaction product is generated from compressed feed gas that is cooled in a heat-exchange system, and using the gas liquefaction product, a storage liquid is provided, and in a second operating mode, using the stored liquid, a low-temperature process liquid is provided that is warmed in the heat-exchange system, obtaining a pressurized fluid that is work-producingly expanded in the energy generation unit.
摘要:
A method for producing electrical energy in a combined energy generation plant which comprises an air treatment unit and a power station unit is proposed. In a first operating mode, air is liquefied to form an air liquefaction product (LAIR) and, in a second operating mode, an air liquefaction product is converted into a gaseous or supercritical state, in which said product is introduced into the power station unit and is used for producing electrical energy. In a third operating mode, air is condensed in the air treatment unit and used in the power station unit directly for producing electrical energy. It is envisaged that, in the first operating mode, the air is cooled to severa temperature levels by two liquid coolants and the air liquefaction product is correspondingy heated. In addition, in the first operating mode, the air is condensed stepwise over several pressure levels.

Method and device for manipulating at least one parameter of a vehicle and used to improve active and passive occupant safety. The vicinity of a vehicle being monitored for the occurrence of at least one relevant event. A vehicle interior being monitored for the actual position of at least one person (vehicle occupant). Signals corresponding to the event or the actual position being supplied to an evaluation unit upon the occurrence of the at least one relevant event and/or on detecting the actual position. The evaluation unit activating at least one active and/or passive safety system of the vehicle as a function of the at least one detected relevant event and the detected actual position of the at least one person.

摘要:
A method of calibrating a sensor system which is used to detect and analyze objects in the path of a vehicle is described. In this method, characteristic data of the objects is detected with the sensor system, and data interpreted as stationary or quasi-stationary objects, taking into account the vehicle's own motion, is sent to a calibration unit. In the calibration unit, the deviation of the instantaneously measured data from data of a model of the objects is determined as the error vector and used for correcting the data of the model for the purpose of minimizing the deviation.
