Next-Generation Thermo-Electric Digital Time Delay Device. Replacement for Current Pyrotechnic Delay Cartridges

Abstract

What is the digital time delay or DTD? (1) A new thermo-electric device which can directly replace many existing pyrotechnic time delay cartridges. (2) Requires no external source of power and does not contain batteries. (3) Provides order of magnitude improvement in timing accuracy. How does it operate? (1) It converts heat energy into electric power using a thermoelectric module. (2) It uses a low power digital micro-controller with a crystal oscillator to accurately measure delay time.
