An apparatus for assembling a solid hydrogen storage system includes a lower support installed to support a lower side of material blocks to be assembled, split covers assembled in multiple stages on an upper side of the lower support and forming therein a closed space in which the material blocks are capable of being assembled, the split covers being configured to be separated in a horizontal direction, and gas injection ports provided in the split covers to inject an inert gas into an inner space of the split covers.

A method for sealing surgical instruments, particularly reusable electric surgical instruments sterilized using an autoclave process, includes providing at least two body shells having a runner system on the mating surfaces, aligning the body shells, securing the body shells in position relative to each other, inserting an injection device into the runner system, injecting an elastomer material from the injection device into the runner system, removing the injection device from the runner system, and curing the elastomer material. The elastomer material seals the housing chamber of the instrument. The elastomer material may bond the body shells together.

Systems and methods for adding buoyancy to an object are described herein. A buoyant material may be enclosed inside a flexible container, heated, and inserted into a free flooded cavity inside the object. The flexible container may then be formed to the shape of the cavity. After the flexible container is formed to the shape of the cavity, the flexible container may be cooled. The flexible container may hold a pre-determined amount of the syntactic material that provides a fixed amount of buoyancy. According to another aspect, systems and methods for packing a vehicle are described herein. In some embodiments, a buoyant material may be molded into the shape of a hull of a vehicle, and a plurality of cutouts may be extracted from the buoyant material which are specifically designed to incorporate one or more instruments.

Systems and methods are disclosed herein for a pressure tolerant energy system. The pressure tolerant energy system may comprise a pressure tolerant cavity and an energy system enclosed in the pressure tolerant cavity configured to provide electrical power to the vehicle. The energy system may include one or more battery cells and a pressure tolerant, programmable management circuit. The pressure tolerant cavity may be filled with an electrically-inert liquid, such as mineral oil. In some embodiments, the electrically-inert liquid may be kept at a positive pressure relative to a pressure external to the pressure tolerant cavity. The energy system may further comprise a pressure venting system configured to maintain the pressure inside the pressure tolerant cavity within a range of pressures. The pressure tolerant cavity may be sealed to prevent water ingress.
