|Abstract||An initiator is provided for a munitions device that is intended to strike a target substantially along a trajectory direction and contains an explosive within a case. The initiator includes a sleeve, first and second anvils and an initiation pellet disposed between the anvils. The sleeve is disposed within the case and adjacent to the explosive, and defines an initiator interior aligned substantially parallel to the trajectory direction. The sleeve includes one or more orifices that extend therethrough between the explosive and the interior, the orifices being disposed adjacent to the pellet. The pellet is composed of a reactive material that chemically responds as a non-explosive to kinetic and thermal stimuli. The first anvil is disposed transverse to the interior and forward of the pellet, while the second anvil is disposed within the interior behind of the pellet, wherein the second anvil translates towards the first anvil substantially along the trajectory direction in response to the device striking the target. The pellet discharges particles through the orifices, the particles being directed into the explosive in response to the second anvil translating towards the first anvil. The sleeve can be disposed within the explosive. The reactive material can be a solid or powdered mixture of powdered aluminum and polytetrafluoroethylene or other fluoropolymer, or alternatively a thermite mixture of powdered metal and metal oxide and may include added polytetrafluoroethylene or other fluoropolymer.|

This patent was granted in 1 year, 354 days, which is a much faster than average speed.
It has 20 claims, which is fewer than average for this category.
Its proximity to basic research is much less than others in this category, and it displays a slower than average technology cycle time.
This patent received far fewer citations from other patents, and references far fewer other patents, as compared to other patents in this category.
This patent had a much faster than average grant time compared to others in this category.
Patent grant time can be influenced by many factors. Activities within the USPTO that are beyond the control of patent attornies can influence grant time, but short grant times can also indicate well-written patents and dedicated efforts to respond rapidly to USPTO office actions with strong arguments. Shorter grant times are preferable, and the scores for this section are inverse measures — higher scores are better.
This patent has fewer claims compared to others in this category.
The number of claims in a patent is correlated with its strength. Because greater claim counts increase the cost of a patent, more claims can indicate the importance an applicant assigns to a patent. Importantly, some may elect to file claims across multiple patents. A higher score in this metric indicates more claims, relative to others in this category.
This patent has received far fewer citations from other patents, than others in this category.
Citations from other patents are an important measure of the significance of a patent. More citations indicate that other technologies build on a patent. Higher scores in this metric are better, and indicate more citations from other patents.
This patent referenced many more citations to other patents, than others in this category.
A lower number of citations to other patents can be a sign of diminished patent strength. More citations indicate dependence on more other technologies. Higher scores in this category are better, and indicate fewer citations to other patents.
This patent has much less proximity to basic research compared to others in this category.
Proximity to basic research is measured by comparing the number of citations to non-patent literature among a cohort of patents. Because most non-patent citations are primary research papers, a higher count indicates greater proximity to basic research.
