Title: Innovations of Peter L. Atkeson

Introduction

Peter L. Atkeson is a notable inventor based in Elkton, MD (US). He has made significant contributions to the field of electronic ignition systems, holding a total of five patents. His work has been instrumental in advancing technologies related to time delay initiators and igniter squibs.

Latest Patents

One of Atkeson's latest patents is the Programmable Electronic Time Delay Initiator. This innovative device includes a digital time-delay circuit that counts in response to a dual-resonator clock. At the end of the programmed time delay, it gates the pre-stored charge on a capacitor to a semiconductor bridge initiator to fire an explosive. The timer circuit features a combined crystal/RC oscillator that ensures high accuracy oscillations, even if the crystal fails. The timer is powered on initially to provide energy to the capacitor, which supplies power to the time-delay and related circuits. An initial ATTENTION pulse initializes the circuitry and starts a watchdog timer that counts a fixed number of clock cycles, resetting the logic if a following WRITE, ARM, or FIRE command is not received. The programming process involves a WRITE pulse and subsequent programming pulses that program a fusible link memory with time-delay information, while an ARM pulse charges the firing-charge capacitor, and a FIRE pulse gates the firing-charge to the bridge initiator to fire the explosive.

Another significant patent is the Low Cost Hermetically Sealed Squib. This electrically actuated igniter squib is created by welding a cup containing a pyrotechnic material to a header inserted in the cup, forming a hermetic seal. The design ensures that the diameter of the header exceeds that of the cup, and the two components are joined by forcing the header into the cup under pressure to achieve a tight, readily welded joint.
