  • Patent number: 12035887
    Abstract: An endoscopic system may include an endoscope including a handle and an elongate shaft extending distally therefrom. The handle may include a non-motorized and non-ratcheting actuation mechanism configured to articulate a distal tip portion of the elongate shaft. The distal tip portion may be articulatable in response to a manually applied force exerted upon the actuation mechanism. Removal of the manually applied force may lock the distal tip portion in its then-current configuration. The non-motorized and non-ratcheting actuation mechanism may include a clutch mechanism actuatable in response to an electrical signal generated in response to sensing a user-applied force to the actuating mechanism by a strain gauge.

  • Publication number: 20220375630
    Abstract: Techniques are described for delivering a metered flow of tritium gas to a fusion power system at a constant (or substantially constant) flow without feedback control being necessary, and while allowing all (or almost all) of the tritium in a reservoir to be delivered to the system. A constant pressure (isobaric) tritium injection system is described comprising a process chamber, at least part of which is flexible, and a regulating chamber arranged adjacent to the process chamber. Tritium in the process chamber may be pushed out of the injection system by managing the pressure of a regulating gas in the regulating chamber. As the pressure of the regulating gas increases, this causes the process chamber to be compressed due to the flexible portion(s) of the process chamber, thereby increasing the pressure of the tritium gas.
