Abstract: A new species of capacitive mass energy storage system employing eutectic liquid metallic materials and 2D/2.5D electrode structures to achieve energy densities capable of replacing battery chemistries as well as petrochemical fuels. The system utilizes metallic bonding principles and submicron-scale electrode separation to sequester high electrical and ionic charge values. Operating at substantially higher voltages than conventional capacitors, the system employs synergistic charge storage mechanisms, and specialized fabrication techniques including capillary printing. Simulations show that the technology provides high energy density simultaneous with rapid charging and near instant discharging capabilities, configurable power output in DC or AC forms, and thermal stability at elevated temperatures. Applications include electric vehicles, autonomous robotics, and medical devices, among others.

Abstract: Embodiments of the present invention provide a cooling module for cooling heat-generating electronic devices in an immersion cooling system. The cooling module includes an integrated pump, which draws immersion fluid from the surrounding dielectric bath and drives it into a pressurized plenum to pressurize the coolant fluid and drive the pressurized coolant fluid through a nozzle plate containing a microconvective nozzle array. The array accelerates the fluid to produce a multiplicity of microjets that impinge on a surface of the heat-generating electronic device to be cooled. The effluent from the cooling module may be directed to flow into and wash over nearby heat-generating devices to help cool the nearby heat-generating devices. The effluent may also be directed to the inlets of daughter cooling modules attached to other heat-generating electronic devices.

Abstract: A liquid cooling system for an electronic device includes a bleed-in reservoir configured to facilitate the separation and removal of entrained gases from a circulating liquid coolant. The bleed-in reservoir is fluidly connected to the main cooling loop of the cooling system via a parallel branch comprising smaller-diameter fluid conduits to ensure a reduced flow rate of liquid coolant through the parallel branch compared to the flow rate through the main cooling loop. The bleed-in reservoir includes an internal chamber configured to receive and hold liquid coolant and a compressible gas volume, and may incorporate internal flow modifying features, such as flow diverters, baffles or perforated plates, to increase residence time, induce turbulence, and enhance gas-liquid separation. Strategic placement of the inlet and outlet ports along the vertical height of the internal chamber walls promotes gravitational separation by leveraging the buoyancy properties of the gas.

Abstract: Embodiments of the present invention provide a reservoir with a flow tunnel for AIO cooling systems. The flow tunnel inside the reservoir is configured to reduce turbulence and air entrainment at the air-coolant interface (ACI) inside an internal chamber of the reservoir body, which maximizes the volume of liquid coolant fluid that is available to be pumped from the reservoir to a fluidly connected cooling module in the closed loop of an all-in-one (AIO) cooling system combatting fluid loss from permeation and transpiration that may occur in the closed loop cooling system, and limits pressure excursions that might otherwise occur in the closed loop through volumetric expansion of the liquid coolant fluid as the temperatures of the AIO system rise from ambient to normal operating temperatures.

Abstract: A portable VOG device is disclosed that will facilitate the effective and efficient screening for TBI in military personnel in forward deployed military settings or remote locations using minimally trained staff. This includes the establishment of a protocol that will provide cost effective pre-screening of military personnel prior to deployment to establish a baseline of brain function prior to possible future injury. The efficiency of the device will promote subsequent follow-up screening to assess the effectiveness of prescribed TBI treatment. Further protocols for diagnosis and rehabilitation applications using the same virtual reality portable device will allow more advanced usage for clinicians providing ongoing evaluation and treatment.

Abstract: Energy storage and conversion systems are, formed when tightly integrated components including thermochemical storage subsystem with a concentration cell to provide very high capacity and high energy density systems. Systems taught here include the unique combination of a thermochemical energy storage module in close thermal communication with a direct energy converter in the form of a concentration cell. A closed-loop thermochemical module receives heat input at a receiving port to drive a reversible chemical reaction. The end-to-end system achieves an ‘on-demand’ functionality because the reagents of said chemical reaction may be safely stored for long periods of time without detrimental effect. When these reagents are again reunited, they produce heat that may be transmitted to the direct energy converter arranged to convert so received heat directly into an electric output suitable for doing work on an external system.
