Abstract: Systems and methods are provided for a high efficiency cold plate system. A high efficiency cold plate system may include an interior surface. A heat source may be configured adjacent to a lower portion of the interior surface. The interior surface may enclose an interior region. The interior surface may also include members extending across the interior surface. The members may be separated by an orifice. The members and interior surface may defined an inlet region and an outlet region. The inlet and outlet regions may be fluidly joined by an orifice separating the members extending across the interior surface. The members may be angled relative to a lower portion of the interior surface. Angling the members may allow the system to constrain and direct fluid flowing through the system to achieve efficient cooling.

Abstract: An exoskeleton system comprising a fluidic actuator and a power transmission that includes: a transmission body that defines a transmission chamber configured to hold a fluid, the transmission body having a first and second end, and a piston that translates within the transmission chamber between the first and second ends of the transmission body, with translation of the piston within the transmission chamber changing a volume of the transmission chamber. The exoskeleton system also includes a mechanical power source coupled to the power transmission configured to cause the piston to translate within respective transmission body to change the volume of the transmission cavity; and a first fluid line that couples the power transmission to the fluidic actuator.

Abstract: Embodiments relate to architectures for pumps responsible for introducing liquid into cylinders reversibly configurable to perform gas compression or expansion. Particular embodiments maintain liquid flow rates in the face of the different pressure profiles (?-P) encountered during various portions of gas compression and gas expansion cycles. In some embodiments, the pump comprises multiple pumping elements per cylinder, at least one pumping element separable with a clutch and designed to spray/not spray during portions of compression/expansion cycles. Embodiments may employ phase difference(s) between the multiple pumping elements to introduce liquid in a desired manner. Mechanisms allowing adjustment in phase of multiple pumping elements, are also disclosed. The liquid may be introduced through sprayers arranged in rings in the cylinder, with rings (or partitions thereof) dedicated to spraying during different portions of compression and/or expansion.
