Patent number: 11674784Abstract: Various types of structures, along with associated systems, are disclosed herein and configured for responding to an energy wave for changing a state of a mechanism to which said structures are operatively coupled. In at least one embodiment, the structure provides a material selectively changeable upon exposure to the energy wave to cause at least a portion of the material to mechanically degrade from a first state to a second state. When the material is in the first state, the material forms a mechanical or electrical link with the mechanism such that a force or an electrical current can be transmitted through the structure. When the material is in the second state, degradation of at least the portion of the material disrupts the mechanical or electrical link and inhibits transmission of the force or electrical current through the structure.Type: GrantFiled: June 24, 2019Date of Patent: June 13, 2023Assignee: JD Pharma, LLCInventor: Joseph Dan Palo

Patent number: 11543224Abstract: An explosive detonating system comprises connectable components to connect/disconnect a pathway that ignites an explosion. A firing actuator activates primers. An adapter connects the firing actuator to shock tube and channels the ignition force from the primers into the shock tube. A cap box houses blasting caps coupled to the end of the shock tube. A priming well is coupled to the cap box/blasting caps and detonating cord. When the firing actuator is initiated, the percussion caps ignite, sending an explosive jet of gas into the shock tube, which ignites an explosive liner. An explosive wave travels through the shock tube and activates the blasting caps, which activate the detonating cord in the priming well. The explosive is placed in a location to provide a desired explosive effect. For example, the system may be employed as a system to breach into structures, remove obstacles and/or barriers, or other applications.Type: GrantFiled: May 19, 2020Date of Patent: January 3, 2023Assignee: River Front Services, Inc.Inventors: Anthony Miles Brown, Toby Justin Harvey, Donald Ray Brown, Thomas Jeffrey Harvey
