Abstract: Embodiments described herein generally relate to a multi-mode heat transfer system. The heat transfer system includes an emitter device. The emitter device includes an inner core surrounded by an outer core having a thickness and an outer surface. A composite material pattern extends through at least a portion of the outer surface and at least a portion of the thickness of the outer core and is thermally coupled to the inner core. The composite material pattern in combination with an optimized emissivity surface coating/paint profile directs a heat from the inner core to an object other than the emitter device.

Abstract: Disclosed herein are an apparatus and method fluid flow measurements which include a pressure transducer and a flexible tube. The pressure transducer is tuned to measure flow speeds having a Reynolds number less than 100 and include an inlet. The flexible tube has a first end fluidly coupled to the inlet and a second end positioned adjacent to and in fluid communication with a plurality of fluid outlets of a microchannel flow structure. Each of the plurality of fluid outlets has a cross section defining an outlet area. The second end has a cross section defining a flexible tube area that is larger than the outlet area.

Abstract: A tunable optical metamaterial system includes a tunable optical metamaterial, an actuator module to selectively activate the tunable optical metamaterial, and a control system to selectively control the actuator module. The tunable optical metamaterial includes a substrate defined by one or more fluid-filled pockets formed by one or more electroactive polymer (EAP) layers defining a reservoir containing a fluid that is induced to a change in volumetric configuration or 3D orientation when electrically activated. The optically active array of resonators are populated on an electroactive surface of the one or more fluid-filled pockets and are optically responsive to the change in volumetric configuration of the one or more fluid-filled pockets. The control module is to selectively control, via the actuator module, the optical properties of the tunable optical metamaterial by causing the electrical activation of the fluid-filled pockets.

Abstract: Embodiments described herein generally relate a multi-mode heat transfer system. The heat transfer system includes an emitter device. The emitter device includes an inner core, a composite material pattern, and a surface coating pattern. The inner core is surrounded by an outer core having a thickness and an outer surface. The composite material pattern extends through at least a portion of the outer surface and at least a portion of the thickness of the outer core and is thermally coupled to the inner core. The surface coating pattern is on the outer surface and is changeable between a low emissivity state and a high emissivity state based on a surface temperature of the emitter device. In the low emissivity state, the emitter device transmits an omni-directional radiation and, in the high emissivity state, the emitter device transmits a focused radiation via the composite material pattern.

Abstract: Embodiments disclosed herein describe manifold microchannel heat sinks having a gridded microchannel assembly with free-form fin geometries for cooling heat-generating devices in the electronics modules. In an embodiment, a manifold microchannel heat sink includes a target surface and a gridded microchannel assembly comprising a plurality of microchannel cells. Each microchannel cell is surrounded by thermally-conductive sidewalls and includes a fluid inlet, a microchannel structure fluidly coupled to the fluid inlet and a fluid outlet. The microchannel structure extends from the target surface and defines a microchannel extending in a normal direction with respect to the target surface. The microchannel structure includes a base plate disposed on the target surface and a three-dimensional fin structure disposed on the base plate. The three-dimensional fin structure has a shape optimized for thermal performance and fluid performance.

Abstract: A fuel cell may include a first fuel cell bipolar plate defining an air layer, a second fuel cell bipolar plate defining a hydrogen layer, and a coolant layer defined by the air layer and the hydrogen layer. A permeable support infill structure, composed of sintered thermally conductive powder particles, is arranged at the cooling layer to prevent flow blockage at the coolant layer, define a thermally conductive path between the air layer and the hydrogen layer, and facilitate coolant flow through the permeable support infill structure.

Abstract: Systems and methods for detecting an anomaly in a power semiconductor device are disclosed. A system includes a server computing device and one or more local components communicatively coupled to the server computing device. Each local component includes sensors positioned adjacent to the power semiconductor device for sensing properties thereof. Each local component receives data corresponding to one or more sensed properties of the power semiconductor device from the sensors and transmits the data to the server computing device. The server computing device utilizes the data, via a machine learning algorithm, to generate a set of eigenvalues and associated eigenvectors and select a selected set of eigenvalues and associated eigenvectors. Each local component conducts a statistical analysis of the selected set of eigenvalues and associated eigenvectors to determine that the data is indicative of the anomaly.

Abstract: Methods, systems, and device for wirelessly charging a device. The inductive charging system includes a power source for providing an electrical charge that is wirelessly transferred or emitted to charge a first device. The inductive charging system includes a configurable grid that is configured to form a first inductive loop and multiple switches. Each switch is configured to open and close to electrically connect different portions of the configurable grid. The inductive charging system includes a processor connected to the multiple switches. The processor is configured to operate the multiple switches to open and close the portions of the configurable grid to form the first inductive loop that wirelessly transfers the electrical charge to the first device.
