A processor-implemented method, system, andor computer program product deploys software images onto a computing system. Under the control of a bidirectional precision pump, a stream-selection valve, and a microprocessor, a series of liquid zones is built up in a holdingmixing coil. The sensor element has a boundary location between a first sensor element region, which faces the process and which is embodied with a high thermal resistance, and a second sensor element region, which faces away from the process and which has a low thermal resistance, and that the temperature sensitive element is arranged in the sensor element at the boundary location. The emissive organic electron transporting layer comprises an organic electron transporting material and an organic hole-trapping emissive material, for example, an organic phosphorescent material that produces emission from a triplet excited state of an organic molecule. The invention makes available an advantageous emergency power supply system for a hydraulic steering system of an industrial truck. An apparatus may include a main body and a transfer unit disposed in the main body.
