Abstract: A method of designing a fuel cell includes executing one or more programs on one or more computing devices having one or more processors to predict a location of one or more liquid regions and one or more vapor regions in microchannels at an air layer of a plate of the fuel cell. Based on the prediction, fluid flow networks for the air layer, a hydrogen layer, and a coolant layer of the fuel cell are simultaneously optimized via homogenized flow optimization. In response to the results of the homogenized flow optimization, one or more multi-scale Turing-patterned microstructures are generated for the air layer and the hydrogen layer. One or more multi-scale Turing-patterned microstructures are generated for the coolant layer by stacking the air layer and the hydrogen layer.

Abstract: Apparatuses and methods for monitoring vital signs. Movement data for a selected body location of a person in a vehicle is generated using a movement sensor positioned remotely with respect to the person. Input data is formed for a machine learning system using the movement data. The input data is processed using the machine learning system to remove noise from the input data and generate a target output that identifies a vital sign of the person.

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: An apparatus comprises a first plurality of optical fibers embedded in a first plurality of fabric strands, a second plurality of optical fibers embedded in a second plurality of fabric strands, and a detector. The first plurality of optical fibers are positioned adjacent to each other and oriented along a first direction and the second plurality of optical fibers are positioned adjacent to each other and oriented along a second direction orthogonal to the first direction. The first and second plurality of optical fibers are configured to receive ambient light emitted onto them. The detector detects the light received into at least some of the first and second plurality of optical fibers and creates data configured to be processed to identify an object adjacent to the apparatus. The data is based on the light received into the first plurality of optical fibers and the second plurality of optical fibers.

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: 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. The coolant layer includes a plurality of coolant microchannels that facilitate flow of a coolant. A permeable support layer is arranged between the air layer and the hydrogen layer to define a gap therebetween to prevent flow blockage of the coolant microchannels while facilitating coolant flow therethrough.
