Patents by Inventor Diana P. Schaeffer

Diana P. Schaeffer 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: 8479651
    Abstract: A pyrotechnic training system includes a firing block assembly housed in a first container, a pressure-armed trigger module having two triggers housed in a second container, and a power pack/switch system that connects the firing block assembly and triggers. The first and second containers are remote from each other, and may be made from common objects that might be found in combat zones. Quick-release pins inserted through components of the firing block prevents their separation by exploding ordinance within the firing block, maintaining close electrical contacts within the firing block. The pressure-armed triggers employ a mechanical system that energizes an electrical circuit when pressure is released. Such triggers are arranged such that opening or moving the container triggers an explosion at the remote firing block assembly.

  • Patent number: 8011928
    Abstract: Mine-like explosion simulators are disclosed herein. According to aspects illustrated herein, a landmine simulator device includes a blast fixture; a lower portion of said blast fixture having a proximal end, a distal end and a hollow area therebetween, said hollow area being configured so as to direct channeling of an audio signature internally for maximum sound; and a top portion of said blast fixture having a top plate and a blast cover, said top plate having an opening for engaging and aligning with said proximal end of said lower portion, and said blast cover being configured so as to release a visible signature externally for maximum exposure.

  • Patent number: 7597047
    Abstract: According to one embodiment, a system for simulating an actual explosion of an explosive device includes one or more firing devices and a control module. A firing device comprises a pyrotechnic device operable to direct a pyrotechnic explosion in a predetermined direction to simulate the actual explosion of the explosive device. The control module receives a trigger signal from a trigger device, which is operable to send the trigger signal in response to a trigger event. The control module detonates the firing devices in response to the trigger signal.
