Abstract: A sterilization, disinfection, sanitization, or decontamination system having a chamber defining a region, and a generator for creating a free radical effluent with reactive oxygen, nitrogen, and other species and/or a vaporizer. A closed loop circulating system without a free-radical destroyer is provided for supplying the mixture of free radicals from the generator mixed with the hydrogen peroxide solution in the form of the effluent to the chamber. The system is used in sterilizing, disinfecting, sanitizing, or decontaminating items in the chamber or room and, with a wound chamber, in treating wounds on a body. The wound chamber may be designed to maintain separation from wounds being treated. Various embodiments can control moisture to reduce or avoid unwanted condensation. Some embodiments can be incorporated into an appliance having a closed space, such as a washing machine. Some embodiments may include a residual coating device that deposits a bactericidal coating on sterilized items.

Abstract: An immersion cooling system and methods for operating the system are described. The system can comprise a vessel configured to hold thermally conductive, condensable dielectric fluid; a pressure controller to reduce or increase an interior pressure of the vessel; a computer component configured to be at least partially submerged within the dielectric fluid; and a fluid circulation system configured to draw the dielectric fluid from a sump area of the vessel, pass the dielectric fluid through a filter and deliver the dielectric fluid to a bath area of the vessel.

Abstract: A system for generating a hash tree with components grouped by component type is provided. Each non-leaf node of the hash tree has a hash of the hashes of its child nodes, and a leaf node has a hash of a component of the hash tree. The system generates, for each component type, a component subtree for that component type based on the leaf nodes that have hashes of the components of that component type. The system then generates a root subtree of the hash tree based on leaf nodes that are the root nodes of the component subtrees. The combination of the root subtree and the component subtrees form the hash tree.
