摘要： A method and system for obtaining motor current measurements from a DC bus current of an inverter that drives a pulse width modulated electric machine is disclosed. The method may include sensing a DC bus current in a sensor located on a bus of an inverter; sampling the DC bus current via an analog to digital converter wherein the sampling is controlled by sampling timing that is based on a pulse width modulation timing of the inverter; and determining three AC phase currents of the motor from the sampled DC bus current.

摘要： The present invention provides improved couplings for conduit systems. A male coupling and a female coupling may be mechanically engaged by inserting the male coupling into a receiver in the female coupling until fastening structures are aligned, and then rotating one or both of the male and female couplings until the fastening structures are overlapping and in interfacial engagement. The male and female couplings provide an efficient coupling solution for end-to-end conduit connection and also addresses a leakage problem in conventional irrigation pipe couplers.

摘要： A catalytic microscale reactor with spiral reactor geometry may have a high surface area to volume ratio, high catalytic surface area, high heat transfer surface area, long residence time, and high single pass conversion. The catalytic surface may be treated with microsphere spacer particles which serve to maintain the space between them at an engineered distance without the need for precise manufacturing techniques. The design of the reactor may allow for a catalyst surface to be removed, uncoiled, refurbished, and recoiled in an automated continuous process. An automated continuous process may be suitable both for initially preparing a new catalytic surface as well as refurbishing a fouled catalytic surface and may reduce the time and cost to prepare a new surface.
