Publication number: 20160110166Abstract: A device for true random number generation is disclosed. The device comprises an antenna and an analog processing unit for analog processing of a signal received from the antenna. An analog to digital (AD) converter is used for converting an analog signal generated by the analog processing unit into a digital signal. An isolation means is applied for temporarily isolating the antenna from the analog processing unit and the AD converter to generate a noise signal. A sampling means is used for sampling output values generated by the AD converter when the antenna is isolated from the analog processing unit and the AD converter. A digital processing unit is used for processing the sampled output values generated by the AD converter. The digital processing unit is configured to generate a random number based on one or more of the output values generated by the AD converter.Type: ApplicationFiled: October 15, 2015Publication date: April 21, 2016Inventors: Nikolaos Moschopoulos, Jan Geert Prummel, Michail Papamichail

Publication number: 20150238714Abstract: A dose counter for a metered dose inhaler includes an incremental counting system for counting doses. The incremental counting system has a main body, an actuator arranged to be driven in response to canister motion and to drive an incremental output member in response to canister motion. The actuator and incremental output member are configured to have predetermined canister fire and count configurations in a canister fire sequence. The canister fire configuration is determined by a position of the actuator relative to a datum at which the canister fires medicament and the count configuration is determined by a position of the actuator relative to the datum at which the incremental count system makes an incremental count. The actuator is arranged to reach a position in the count configuration at or after a position in the canister fire configuration.Type: ApplicationFiled: April 29, 2015Publication date: August 27, 2015Inventors: Declan Walsh, Derek Fenlon, Simon Kaar, Jan Geert Hazenberg, Dan Buck, Paul Clancy, Robert Charles Uschold, Jeffrey A.
