US12618655 - Shock initiation of non-electric shock tube

Embodiments of the disclosure are directed to a shock initiation system for initiating shock in a shock tube for demolition. In some embodiments, the shock initiation system comprises a reusable discharge unit and a replaceable shock initiation platform. The reusable discharge unit may comprise a power source, a timer, a switch, and user inputs and may function to store a time, countdown the timer, and generate and transmit an electrical energy to the replaceable shock initiation platform. The shock initiation platform may receive the electrical energy from the discharge unit overpowering a resistor disposed on the shock initiation platform. The resistor may then detonate providing an initiation shock to a proximally disposed shock tube, thereby initiating shock in the shock tube.

US12560415 - Integrally formed high-G shock metal isolator in a projectile

A projectile is integrally formed with a high-G shock isolator to isolate a protected device. The isolator includes a pattern of cut-outs formed around a circumference of a metal casing that defines flexures and supports and coupling paths that zigzag therethrough. Symmetry about the longitudinal axis of the projectile defines springs that are colinear with the principal axes of the projectile with a resonant frequency selected to attenuate shock inputs to levels acceptable to the protected device. The isolator is suitably provided with forward and aft stops to ensure isolator survivability. The aft stops are positioned in the cut-outs to prevent the flexures compressing beyond the yield strength of the casing material. The forward stop includes a structure rigidly attached behind the isolator that extends forward to engage a forward-facing surface of the isolator to prevent the flexures from stretching beyond the yield strength of the casing material.
