  • ELECTRONICALLY GENERATED/INITIATED SIGNATURE PRODUCING TRAINING CARTRIDGE
    Publication number: 20240102777
    Abstract: Training ammunition that may be utilized by the U.S. Army, Marines and other Armed Forces that conduct training exercises with about 20 mm to 155 mm cartridges. The munition would electronically generate/initiated a signature that would become present at the target. The user would be able to observe the signature with the unaided eye during day or night training, or with devices such as night vision goggles/monocular or thermal sites. The generated signature would not utilize any explosives or pyrophoric iron powders, and would not create an increased fire hazard risk to the user. The munition would be able to survive typical rough handling and firing weapon malfunctions without becoming unusable, or causing delays in training exercises.

  • Titanium alloy contact ring element having low modulus and large elastic elongation
    Patent number: 10576266
    Abstract: A method of forming a medical device contact element includes annealing an elongated rod of Ti-15Mo alloy material to form an annealed rod having a Young's Modulus of less than 13.5 Mpsi and an elastic range or strain of at least 0.7%. Then forming a contact ring element from the annealed rod and assembling the contact ring element into a medical device. Contact rings and lead receptacles including the same are also described.
