Abstract: A system and method for providing updates to medical devices is disclosed. In one example, the medical devices are configured to pull update files in response to the reception of an update message from a server. Once the update files are downloaded by a medical device, the update files can be installed. While the medical device pulls the update files, the medical device can continue with its normal operation. If desired, a user can select which medical devices should be updated, based on any desired factors, such as the physical location of the device, the model of the device, the type of device, and the way the device is being used.

Abstract: A method for producing alane is provided. The method comprises forming a solution comprising an alane adduct and a Lewis acid. The alane adduct comprises alane and a coordinating ligand. The method further comprises exposing the solution to a laser or high-power light at a at least one wavelength selected to cause dissociation of a bond between the alane and the coordinating ligand, resulting in crystallization of the alane and binding of the coordinating ligand to the Lewis acid after dissociation and separating the crystallized alane from the coordinating ligand and Lewis acid.

Abstract: Disclosed are high enthalpy thermochemical energy storage materials that exhibit high thermal conductivity and stability at high temperature reaction conditions. Disclosed materials include hydride-based alloys that can undergo high temperature reversible hydrogenation/dehydrogenation reactions without phase change of any metal or metalloid components of the alloy. The materials undergo a reversible exothermic hydrogenation reaction to form a metal hydride and a ternary alloy that includes a high thermal conductivity metal that, in its pure state, would exhibit a phase change at the hydrogenation reaction conditions.

Abstract: Disclosed are thermochemical energy storage materials that exhibit high enthalpy of reaction for an exothermic hydrogenation reaction at high temperature reaction conditions. Disclosed materials include titanium-aluminum-vanadium based alloys that can undergo high temperature reversible hydrogenation/dehydrogenation reactions. The materials include aluminum and vanadium in conjunction with titanium in amounts designed to encourage the high enthalpy of reaction and are substantially free of materials that would lower the enthalpy of reaction.

Abstract: Disclosed are systems and methods that utilize a solid hydrogen storage material, e.g., a metal hydride as a fuel source for operating a vehicle. Disclosed systems utilize the pressure of a hydrogen storage tank as a controlling factor for release of hydrogen from a solid hydrogen storage material. Disclosed systems are particularly beneficial for use with unmanned aerial vehicles.

Abstract: Highly efficient and universal biomass conversion methods are described. Methods utilize a base-catalyzed decarboxylation reaction in a conversion process carried out in the presence of excess base to overcome carbonate formation from CO2. Methods can efficiently convert all components of a biomass feedstock to liquid hydrocarbons and carbon dioxide byproduct. The process has several versions: hydrolysis and alcoholysis, etc. The chemical process can be carried out with nearly 100% conversion for any type of biomass feedstock and requires no expensive or complicated pretreatment. The conversion reactions can be carried out at moderate temperatures of 170-300° C. and form a product that can include a mixture of hydrocarbons and oxygenated hydrocarbons, including alcohols and phenol derivatives.
