  • Force-activated thermal battery for use in a wellbore
    Patent number: 10590746
    Abstract: A thermal battery positioned in a wellbore can be force activated by a device. The device can include a body coupled to a thermal battery positioned in a wellbore. The body can include a piston retained at a first position in an inner area of the body. The piston can move from the first position to a second position in response to a force applied to the body. The thermal battery can be activated by moving the piston to the second position.

  • Solid-state overvoltage firing switch
    Patent number: 10415945
    Abstract: An assembly can include solid-state overvoltage firing switch operable to control an explosive device. The solid-state overvoltage firing switch can include a substrate layer. The solid-state overvoltage firing switch can also include a conductive anode and a conductive cathode positioned on the substrate layer. A gap can physically separate the conductive anode from the conductive cathode. The conductive anode can be operable to receive a voltage from a power source. The solid-state overvoltage firing switch can further include an insulator layer adjacent to the conductive anode and the conductive cathode. At least part of the insulator layer can fill the gap. The insulator layer can cover a first portion of the conductive anode and a second portion of the conductive cathode.
