    摘要: A single phase redundant power supply system may include a first power supply having an input coupled to a first phase voltage in a polyphase power distribution system and an output coupled to a load for supplying an amount of DC power to the load, and a second power supply having an input for coupling to a second phase voltage in the polyphase power distribution system and an output coupled to the load for supplying an amount of DC power to the load. At least the first power supply is configured to reduce phase current imbalances in the polyphase power distribution system by adjusting the amount of DC power supplied to the load by the first power supply and the amount of DC power supplied to the load by the second power supply.

    摘要: The liquid crystal grating substrate includes a base substrate, and several bar-like signal electrodes and several bar-like common electrodes formed at an identical layer on the base substrate. The signal electrodes and the common electrodes are arranged alternately and parallel to each other. The liquid crystal grating substrate further includes a signal electrode input line connected to a first end of the signal electrode and a common electrode input line connected to a second end of the common electrode. Respective first ends of the signal electrode and the common electrode are arranged close to one side of the base substrate, respective second ends of the signal electrode and the common electrode are arranged close to the other side of the base substrate opposite to the side, and the signal electrode input line and the common electrode input line are arranged at a layer identical to the signal electrode.

    摘要: A method may include mapping a first program to a context-free grammar. Grammar transformations may be performed on the context-free grammar to produce a transformed context-free grammar representing the first program. A second program having a program structure different than a program structure of the first program may be constructed from the transformed context-free grammar.
