Abstract: A method for improving uniformity of an electromagnetic field inside a static microwave resonant cavity is provided. The overlap between a nodal point in one mode and an antinodal point in another node inside a microwave resonant cavity is realized by using two different types of anisotropic media, thereby improving distribution uniformity of an electromagnetic field inside a static resonant cavity. The method can reduce the complexity of cavity mechanisms of a microwave oven having a turntable and a flat panel microwave having an electromagnetic stirrer and improve static microwave treatment uniformity, thereby promoting the application of high-temperature and high-power microwave treatment in the fields such as microwave sintering, microwave smelting, and microwave chemical industry.

Abstract: Properly parking personal mobility vehicles (PMVs) is an important for safety and public satisfaction. The large number of daily rides of ride-share PMVs makes it impossible to verify manually that each PMV is properly parked. Aspects of this disclosure include systems and methods for verifying that PMVs are properly parked. These systems and methods can include training a machine learning model on a server. The system can request that users submit images to the server, such that the server can verify that the user properly parked the PMV. The server can transmit a finished indication when it determines that the user properly parked the vehicle. The server can transmit instructions to the user to take various actions when it determines that the user improperly parked the vehicle or when the image is insufficient to determine whether the user properly parked the vehicle.
