Latest Patents

One of Lei He's latest patents is focused on in-place resynthesis and remapping techniques for soft error mitigation in FPGA. This innovation addresses the sensitivity of static memory (SRAM) based Field Programmable Gate Arrays (FPGAs) to single event upsets (SEUs). The methods described, including in-place reconfiguration (IPR), in-place X-filling (IPF), and in-place inversion (IPV), allow for the reconfiguration of LUT functions without the need for rerouting, thus improving FPGA designs efficiently. Additionally, for FPGAs with a decomposable LUT architecture, an in-place decomposition (IPD) method is introduced, which remaps a LUT function into multiple smaller functions, utilizing the unused outputs of the LUT.

Another significant patent by Lei He is related to smart electric vehicle (EV) charging and grid integration apparatus and methods. This expert system manages a power grid with charging stations connected to electric vehicles. It selectively backfills power from connected EVs to the grid through a grid tie inverter. The system accommodates user preferences regarding charge time, cost, and station capabilities while ensuring that the power grid capacity is not exceeded. A robust state of charge (SOC) calculation method is also presented, which can accommodate various battery types and current profiles.
