摘要： A magnetic levitation imitation flame device includes a mounting base, a flame member, a positioning bracket, a first magnet, and a second magnet. The positioning bracket is fixed in the mounting base. The first magnet is disposed on the flame member. The flame member is disposed on the positioning bracket and protrudes outwards from the mounting base. The second magnet is fixed at a lower end of the positioning bracket. The first magnet and the second magnet are arranged up and down. Magnetic poles thereof facing each other have same polarity so that the flame member is levitated relative to the positioning bracket under a repulsive force of the first magnet and the second magnet. Thus, the flame member swings with big angle, naturally and realistically, and saves electric energy. In addition, an imitation flame lamp is also provided.

摘要： Various examples are provided for renewable energy control. In one example, among others, a system includes a PV source, a multi-core processor load, and a solar power manager configured to adjust an operating point of the PV source about a maximum power point by dynamically adjusting a transfer ratio and a load level. In another example, a method includes sensing an output current supplied to a multi-core processor load by a power converter at a first transfer ratio, sensing another output current supplied at a second transfer ratio, and determining an operating point of the PV source with respect to a maximum power point based upon the output currents. In another example, a system includes a power manager configured to switch servers between a renewable energy supply and a utility energy supply based at least in part upon a budget level and the load power consumption.

摘要： An endless electrophotographic member, such as a developer roller, which indicates an improved resistance to nip banding. The improvement to nip banding may be provided by the use of an organic salt within a roller surface region. The roller may provide, at a nip location, a resistive surface layer having an electrical resistance that avoids the development of nip banding and relatively dark regions on printed media.
