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.

The patent describes a shock initiation system designed to activate a shock tube for demolition purposes, featuring a reusable discharge unit and a disposable shock initiation platform. When electrical energy is supplied to a resistor on the platform, it detonates to generate a shock that initiates the shock tube positioned nearby.

Claim 1

1 . A shock initiation system for initiating shock in a shock tube, the shock initiation system comprising: a discharge unit, comprising: a power source configured to provide electrical energy; a switch; and discharge unit leads; a disposable shock initiation platform configured to support electrical components and further configured to selectively couple directly to the discharge unit; a resistor electrically coupled to the discharge unit leads of the discharge unit and disposed on the disposable shock initiation platform, wherein the resistor is configured to detonate when the electrical energy is provided by the power source to the resistor via the discharge unit leads when the switch is closed; and a housing configured to entirely house the discharge unit and the disposable shock initiation platform, the housing comprising a shock tube hole in proximity to the resistor, wherein the shock tube hole is configured to receive the shock tube and position a proximal end of the shock tube adjacent the resistor with the resistor positioned outside of the shock tube, wherein detonation of the resistor provides energy to the proximal end of the shock tube, thereby activating the shock tube. a discharge unit, comprising: a power source configured to provide electrical energy; a switch; and discharge unit leads; a power source configured to provide electrical energy; a switch; and discharge unit leads; a disposable shock initiation platform configured to support electrical components and further configured to selectively couple directly to the discharge unit; a resistor electrically coupled to the discharge unit leads of the discharge unit and disposed on the disposable shock initiation platform, wherein the resistor is configured to detonate when the electrical energy is provided by the power source to the resistor via the discharge unit leads when the switch is closed; and a housing configured to entirely house the discharge unit and the disposable shock initiation platform, the housing comprising a shock tube hole in proximity to the resistor, wherein the shock tube hole is configured to receive the shock tube and position a proximal end of the shock tube adjacent the resistor with the resistor positioned outside of the shock tube, wherein detonation of the resistor provides energy to the proximal end of the shock tube, thereby activating the shock tube.
