摘要： Multi-phase thermal control systems, evaporators, variable porous wick elements, heat transfer structures, and methods for their production are provided. Two-phase evaporators for use in such multi-phase thermal control systems are also provided. Two-phase evaporators incorporate a vapor plate body having there three major layers: a vapor channel network, a wick, and a liquid channel. The vapor channel network comprises a plurality of extrusions (e.g., vapor pillars) and associated channels (e.g., vapor channels) configured to allow a vapor to flow therethrough. The wick comprises a porous body configured to be disposed between the vapor channel network of and the liquid flow reservoir.

摘要： Amorphous metal thermal management devices are described. The amorphous metal thermal management devices are advanced heat transfer systems that utilize the unique properties of amorphous metal to transfer heat away from components that generate heat in numerous applications. These devices feature either rigid or flexible vapor chambers, for dissipating heat and can be used to cool a wide range of devices. The resulting cooling solution is both effective and reliable.

摘要： An apparatus and method of uniformly heating, rheologically softening, and thermoplastically forming metallic glasses rapidly into a net shape using a rapid capacitor discharge forming (RCDF) tool in combination with an electromagnetic force generated by the interaction of the applied current with a transverse magnetic field. The RCDF method utilizes the discharge of electrical energy stored in a capacitor to uniformly and rapidly heat a sample or charge of metallic glass alloy to a predetermined “process temperature” between the glass transition temperature of the amorphous metal and the equilibrium melting point of the alloy in a time scale of several milliseconds or less, at which point the interaction between the electric field and the magnetic field generates a force capable of shaping the heated sample into a high quality amorphous bulk article via any number of techniques including, for example, injection molding, dynamic forging, stamp forging, and blow molding in a time scale of less than one second.

摘要： Harmonic drives are used widely in robotics as a method for achieving high gear reductions and for driving force transmissions. The harmonic drive is made a three components: a wave generator, a flexspline, and a circular spline. Embodiments described flexsplines for a metal strain wave gearing. The cup of the flexspline is free from sharp edges and with a rounded bottom with a curvature maximized based on the geometry of the flexspline. Compared to a steel flexspline, implementations of flexsplines will have the same outer diameter, the same number of teeth and profile, the same input shaft/base, the same wall thickness near the teeth, but comprise a rounded bottom where the input shaft/base transitions to the straight wall of the flexspline, providing improved performance of BMG flexsplines by reducing low cycle fatigue failures due to stress concentrations.
