Abstract: A sterilization device for sterilizing open packaging containers with electron beams includes a chamber having at least one electron beam emitter adapted for sterilization of at least an interior surface of the packaging container through an opening of the packaging container, and a sensor configured to measure a dose parameter of the at least one electron beam emitter. A method of sterilizing open packaging containers with electron beams includes sterilizing at least an interior of the packaging container, through an opening of the packaging container, with an electron beam emitter arranged in a chamber, and measuring a dose parameter of the at least one electron beam emitter by a sensor.

Abstract: The invention relates to a sterilization device for sterilizing packaging containers with electron beams in a filling machine. The sterilization device comprises at least one first electron beam emitter adapted for sterilization of at least the interior of the packaging container and at least one electron beam emitter adapted for sterilization of at least the exterior of the packaging container. The invention further comprises a method for sterilizing packaging containers.

Abstract: To provide a voice response unit for use with a telephone communication system, which is able to authenticate a user. Information-providing sites 8, 11 which provide a service using the voice response unit, has user databases 9, 12 for storing the information identifiable of a service subscriber. On the other hand, a voice response unit 5 is provided with a similar user DB 6. If a new subscription or cancellation arises for the service using the voice response unit 5 in the information-providing sites and contents of the user database 9 is changed, a database update instruction is transmitted to the voice response unit 5, so that contents of the user DB 6 is synchronized with contents of the user database 9 or 12. The voice response unit 5 makes authentication of the subscriber using the user DB 6, and provides voice information only to a valid subscriber.
