Abstract: The invention relates to a coin verifier which comprises a support for supporting a coin during verification. The coin verifier is characterised in that the support comprises two shutters which are arranged opposite to each other. The shutters support the coin in a v-shaped manner when closed. The inventive coin verifier comprises a recess for retaining a coin during verification and is characterised in that the recess is terminated by two outlets. The outlets are closeable by the shutters for selectively dumping the coin through one of the two outlets. Further, a method for verifying a coin is disclosed which comprises the steps of maintaining/retaining the coin in a retainer equipped with sensors, verifying the coin by the sensors and selectively opening one of two shutters. The choice of the shutter which is opened depends on the result of the verification, in particular whether or not the coin is accepted.

Abstract: A method of monitoring pressure of a gas species up to at most a predetermined maximum pressure value is disclosed. The method includes exposing the gas species to transmission of laser light, periodically modulating the wavelength of the laser light over a wavelength band including at least one absorption line of the gas species, optoelectrically converting the transmitted laser light, thereby generating an electric output signal, performing at least one of first filtering the electric output signal with a filter characteristic having a lower cut-off frequency not lower than a transition frequency and of second filtering the electric output signal with a bandpass filter characteristic having an upper cut-off frequency not higher than the transition frequency and a lower cut-off frequency above the modulation frequency of the periodic wavelength modulation. The output of at least one of the filterings is evaluated as a pressure indicative signal.
