For example, an application for a patent for this paper summarizes the equipment to ensure that solar cells have enough voltage power supply or battery charging method. When the application is released in 2008, battery maintenance method of battery maintenance engineer method it can be traced back to the apple iPod. Apple to look at the sun, the grass incense plate exposure as ipod source of energy. The '& other; Power management circuits and solar cells & throughout; Applications can be traced back to August 2008, grain fragrant plate exposure and officially released on Thursday. A week ago, the company announced a patent application about home energy management. A recent patent application involves the power electronic equipment, used to manage multiple current of solar cells on equipment. In this case, the solar net, apple engineers describes a method of China solar energy network, can effectively use the wire in the home to manage the power and data flow, solar portal, for a variety of electronic equipment power supply. Solar energy equipment, however, this does not seem to be apple first solar equipment related patent applications. Do cabinet diagonal techniques of apple employees have applied for a use integrated the patent of the solar cell power for electronic devices. 2006 patent applications are not separate solar panels, but imagine a small device, such as the iPod, the surface has a transparent solar cells. Power station in October 2006, the solar power network, a more general patent & other; Portable devices on the solar battery & throughout; Submitted by at least one of the same person.
