Abstract: The invention relates to a method and a device for enabling a validated money transfer between a sending and a receiving person via a sending and a receiving financial institution, where a request to a validation agent for validation of a money transfer replaces normal time consuming cross border security checks. The validation agent, being unaffiliated with the sending financial institution and the receiving financial institution, administers a data base comprising validated transfer agreements, which agreements specifies at least the identity of a sending person and of a receiving person. A validation of a transfer is executed at the validation agent by comparing current transfer data with information specified in the validated transfer agreements.

Abstract: An arrangement for wireless transmission of signals using a serial two-conductor data bus, the arrangement including a clock conductor and a data conductor connected to a transmitter, a receiver and a demodulator, the transmitter including an oscillator, and further including a modulator which effects modulating the oscillator generated signal in dependence on the clock conductor signal and the data conductor signal respectively. The modulator (3) is operative in carrying out on the oscillator generated signal two significant, separate modulation steps which do not coincide in time, thereby to form two mutually independent signal channels (4,8;5,10), of which a first channel (4,8) is intended for data signals and the other channel (5,10) is intended for the clock signals.

Abstract: An arrangement for monitoring a transducer, or detector, which produces an analogue or digital output signal corresponding to a state sensed by the transducer. The invention is characterized in that the transducer includes activatable and deactivatable elements (RB 3, 23) which are intended to influence the transducer in a manner to cause the transducer to produce a signal which deviates from the actual state detected by the transducer, and in that there is provided a control circuit (10) which is intended to activate and/or deactivate the elements in a predetermined sequence, in response to the signal produced by the transducer. The arrangement also includes a control device for detecting the transducer output signal and comparing changes in the output signal in dependence on the activation and/or deactivation of the elements (RB 3, 23). The control device is constructed to detect whether or not the function of the transducer is correct, on the basis of this comparison.
