Single-phase generator The early generators for those single-phase traction networks are single-phase generators. Even with newer three-phase motors which were introduced to some modern trains, the single-phases transmission for traction networks survive their time and are still in use in many railways today. However, many traction power stations have replaced their generators over time to use three-phase generators and convert into single-phase for transmission. In the early development of hydroelectricity, single-phase generators played an important role in demonstrating the benefits of alternating current. In 1891, a 3,000 volts and 133 Hz single-phase generator of 100 horsepower was installed at Ames Hydroelectric Generating
Single Use Medical Device Reprocessing these reprocessed devices on the market, under the condition that third-party reprocessors would be treated as the manufacturer and would meet the same criteria as the original equipment manufacturers (OEMs) of the medical device. Following the implementation of FDA regulation, the U.S. Congress codified these standards and other requirements in the Medical Device User Fee Act of 2002. Original equipment manufacturers undergo a thorough analysis to determine whether a device should be single-use or reusable. Factors in determining to label a device single-use include but are not limited to possible infection/sterility concerns and the risk of reduced efficacy. Depending on
