Ionic Liquids as Lubricant Additives for Tailoring the Lubricant Electrical Conductivity

202205091 // Chemicals?// Transportation

Electric vehicle drive fluids must have a high dielectric constant to avoid current leakage or even short circuits. On the other hand, lubricants should possess sufficient conductivity to allow static electricity to be released. Bearings and other moving parts often have a static charge built up that can break the lubricant film where it interfaces with the part, resulting in electrical arcing. Repeated arcing degrades the fluid and compromises the system. This technology consists of additives that manage lubricant electrical conductivity.

Integration of Coils and Capacitors in Wireless Charging Systems

202205252 // Energy and Utilities //?Transportation

Wireless charging systems work best when they operate at high frequencies that match their resonant frequency, which helps increase the distance over which power can be transferred and makes the process more efficient. However, operating at these high frequencies can lead to high voltages across the system's inductors and capacitors, which are the components that store and transfer energy. Using individual, separate components often makes the system less efficient and more complicated to manage. To improve this, the technology now integrates tuning capacitors directly with the transmitter and receiver coils. This integration leads to enhanced efficiency and better control of the charging system.

Method for Commissioning Power System Testbeds with HIL

202305372 //?Energy and Utilities?// Manufacturing

Electrical utility substations are wired with intelligent electronic devices (IEDs), such as protective relays, power meters, and communication switches. Substation engineers commission these IEDs to assess the appropriate measurements for monitoring, control, protection, and communication applications. But the meters and protective relays could measure the phase voltages and currents on buses with different error percentages. This technology provides a method for commissioning test beds of power systems with a real time simulator and hardware in the loop. This technique finds these errors and allows the system to perform the needed corrections based on the power system application.

Automotive Secure Hijack, Intrusion, and Exploit Layered Detector (Auto-SHIELD): A Vehicle-Agnostic Approach to Controller Area Network Intrusion Detection

202305427 // Security and Defense //?Transportation

Modern automobiles are operated by small?computers that?communicate critical information via a broadcast-based network architecture called controller area network (CAN). Previous research has demonstrated risks due to inherent vulnerabilities within CAN architecture. While automotive cybersecurity is growing as a critical national security asset, manufacturers' implementation of security controls is inconsistent and largely unregulated. Thus, after-market security technologies have become vital to the transportation cybersecurity ecosystem. Auto-SHIELD contributes to the cybersecurity posture of vehicles and fleet organizations by deploying an ensemble of CAN-based intrusion detection technologies on live CAN data. Auto-SHIELD is highly configurable and modular, focusing on the ease of development and implementation of new and current detection algorithms.

Self-Repairing Oxygen Evolution Reaction Catalysts for Electrolysis

202405572 //?Chemicals?//?Energy and Utilities

This invention improves the initial treatment process for stainless steel (SS) electrode activation, resulting in nickel-rich SS electrodes that perform exceptionally well in oxygen evolution reactions (OER), ranking among the best compared to all other nickel-iron-based catalysts. These electrodes are also highly stable, with a very slow degradation rate of 0.022 millivolts per hour under significant workload conditions for 500 hours. Further analysis of both the electrodes and the electrolytes before and after use confirms that the nanometer-scale NiFe catalyst layer can effectively rebuild itself from the underlying metal substrate even under severe OER conditions.
