Abstract: A method for managing a web application initiated by a user is disclosed which enables navigation between two or more wizards while executing said web application. Predefined instructions ensure that a user can execute a plurality of steps in different orders when navigating between two or more wizards without losing any data that has been executed in a previous step. A wizard engine is also disclosed which is adapted to execute the suggested method.

Abstract: A device for counting the edges of electric pulses is disclosed and comprises a first capacitor connected in series with a pump circuit, which comprises a first resistance in series with a first diode connected in parallel with a second resistance, and a second capacitor connected in parallel with the first resistance. When a voltage, which is caused by one of the edges of an electric pulse, is applied across the first capacitor and the pump circuit, the first and second capacitors are charged in series with a charge that is essentially determined by the second capacitor. A first input of a comparator is connected to the connection point between the first capacitor and the pump circuit and a second input of the comparator is connected to a comparison potential, in order to indicate that a given approximate number of pulses have been counted when the voltage across the first capacitor exceeds a threshold level determined by the comparison potential.
