The composite electrolyte includes a ceramic electrolyte scaffold defining a plurality of interconnected pores having a porosity of 45 to 55%. A crosslinked polymer electrolyte is disposed within the plurality of pores. A surface protection layer, including a linear polymer electrolyte is disposed on an exterior surface of the ceramic electrolyte scaffold. A method of manufacturing a composite electrolyte is also provided. The method includes combining a ceramic electrolyte, a binder, and a solvent to give a ceramic electrolyte slurry cast to give a ceramic electrolyte layer. The ceramic electrolyte layer is sintered to give a porous ceramic electrolyte scaffold defining a porosity of 45 to 55%. A polymer precursor solution is prepared and used to infiltrate the ceramic electrolyte and then cured.

Abstract: Privacy-preserving security screening using facial images is disclosed. The screening may comprise encoding a facial image into a latent vector using a first pre-trained machine learning model, shuffling the latent vector using an invertible transformation in a latent space to generate a shuffled latent vector and converting the shuffled latent vector into a landscape image using a second pre-trained machine learning model. The landscape image may be used to security screening and compared with reference landscape images.

Abstract: A hybrid additive manufacturing and thermoforming method is provided. The method includes additively manufacturing one or more reinforcing structures directly onto a polymer sheet before shaping the polymer sheet onto a mold and/or while the polymer sheet is shaped onto a mold. By leveraging the design control of additive manufacturing, reinforcing structures can be deposited onto the polymer sheet as needed based on the intended application. These reinforcing structures can comprise standard infill patterns or complex custom core designs. The present invention provides an innovative way in which to mass produce custom thermoformed components with an optimal mechanical response.

Abstract: A Bayesian learning approach for stability boundary and optimal parameter identification in milling without the knowledge of the underlying tool dynamics or material cutting force coefficients. Different axial depth and spindle speed combinations are characterized by a probability of stability which is updated based upon whether the result is stable or unstable. A likelihood function incorporates knowledge of stability behavior. Numerical results show convergence to an analytical stability lobe diagram. An adaptive experimental strategy identifies optimal operating parameters that maximize material removal rate. An efficient and robust learning method to identify the stability lobe diagram and optimal operating parameters with a limited number of tests/data points.

Abstract: An improved power-split control system for managing a load profile of a fuel cell in a fuel cell electric vehicle (FCEV) is provided. The power-split control system is operable to actively manage the power demand between the fuel cell and the battery of a FCEV to optimize the operational life of the fuel cell. The power-split control system can use information gathered solely from historical drive cycle data or from historical drive cycle data combined with look-ahead eHorizon data. The power-split control system meets a power demand by operating the powertrain in either a battery charge sustaining mode or a battery charge depletion mode. The power-split control system is also configured to control the power distribution (to the electric motor) from the fuel cell and the battery in a manner that minimizes the degradation of the fuel cell.

Abstract: A wireless power transfer (WPT) device includes an in-wheel electric motor having a rotor and a stator having at least one phase coil, a resonant network, and at least one switch configured to selectively connect the resonant network to the phase coil and disconnect the resonant network from the at least one phase coil. A processing device is configured to determine that the at least one phase coil is adjacent to at least one transmitter coil of a WPT transmitter that transmits high-frequency AC power, and operate the at least one switch to close a connection between the resonant network and the phase coil. The phase coil is configured as a receiver coil to receive the high-frequency AC power from the at least one transmitter coil when the at least one switch is closed.
