Patents by Inventor Andreas Schellhorn

Andreas Schellhorn has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8820241
    Abstract: A safety device for a fuze of a projectile that includes a detonating device for detonating the fuze. The safety device has a safety unit with a processor for safeguarding a detonation process of the detonating device. The safety unit contains a sensor unit configured to output a disengagement signal at a predetermined acceleration state. The processor is set up to output a control signal to release the safety unit in accordance with the presence of the disengagement signal. A low-acceleration state of the flight of the projectile can thus be detected and used as release parameter.
    Type: Grant
    Filed: November 5, 2010
    Date of Patent: September 2, 2014
    Assignee: Junghans Microtec GmbH

  • Patent number: 8161878
    Abstract: A safety and arming unit for a fuze of a projectile has a rotor for interruption of a firing chain. The rotor can rotate from a safe position to an armed position. In order to allow the safety and arming unit to be designed to be physically compact and such that it can be assembled easily, it is proposed that it has a first and a second rotor safety device which each engage in the rotor in order to block rotor rotation to the armed position, wherein the first rotor safety device is designed to carry out a release movement by virtue of its inertia during a launch acceleration of the projectile, and the second rotor safety device has a pyrotechnic charge for producing a release movement.
