Abstract: Provided are a grounding impedance measurement circuit and a grounding impedance measurement method. The grounding impedance measurement circuit detects a power supply voltage of an isolated alternating current power supply by means of disposing a power supply voltage detection circuit between a live wire and a neutral wire at the isolated alternating current power supply. Furthermore, by forming an alternating current positive half-cycle detection branch and an alternating current negative half-cycle detection branch between the live wire and the neutral wire at the isolated alternating current power supply as well as between a live wire and a neutral wire at a power wire of an electrical device, the grounding impedance value of the live wire and the grounding impedance value of the neutral wire can be accurately detected, such that an output line having an abnormal grounding impedance can be quickly identified.

Abstract: An Operational Technology (OT) device database is trained by interrogating physical OT devices over the data communication network, and from responses, generating a profile for each interrogated physical OT device, each profile comprising at least data used to set up decoy OT devices that are virtualized to mirror each interrogated physical OT device.

OT device profiles are selected from the OT device database based on the list of local physical OT devices. The selected OT device profiles are transmitted to the specific deception appliance, at the remote private network. The specific deception appliance maintains VM machines for running decoy OT devices, based on the selected OT device profiles, on the remote private network.

Abstract: Embodiments of the present disclosure propose an Erasing-based Lossless Floating-point compression method, i.e., Elf. The main idea of Elf is to erase the last few bits (i.e., set them to zero) of floating-point values, so the XORed values are supposed to contain many trailing zeros, where the erased bits are determined based on the decimal place count and the digits on the exponent bits.

Abstract: The present invention provides a multi-load wireless power transfer system based on high-order Anti-PT symmetry. By introducing a “W-shaped” anti-resonance mode into a basic WPT platform, an effective Anti-PT non-Hermitian system is conveniently constructed. The “level attraction” of the anti-resonance mode is combined with the “level splitting” of the anti-resonance mode and the resonance mode, to study the “level pinning” effect of high-order Anti-PT symmetry. Compared with the traditional resonant WPT, the anti-resonant WPT has higher security, stability, transfer efficiency, and flexibility. Considering the miniaturization and integration of devices, a “meta coil” is designed by using a “synthetic dimension”, and used to construct a high-order Anti-PT symmetric system, thereby achieving multi-load efficient WPT. The new WPT technology based on the “level pinning” effect of high-order Anti-PT symmetry provides a good application research platform for enriching non-Hermitian physics.
