To provide a more consistent experience between devices, Windows Phone 7 devices are required to meet a certain set of hardware requirements, which Andy Lees, Microsoft's senior vice president of mobile communications business, described as being "tough, but fair." [75] All Windows Phone 7 devices, at minimum, must include the following: [76] [77]
Windows Camera is an image and video capture utility included with the most recent versions of Windows and its mobile counterpart.

The C-rate is defined as the charge or discharge current divided by the battery's capacity to store an electrical charge. While rarely stated explicitly, the unit of the C-rate is h −1, equivalent to stating the battery's capacity to store an electrical charge in unit hour times current in the same unit as the charge or discharge current. The ...
2009 Nobel Prize in Physics laureates George E. Smith and Willard Boyle, 2009, photographed on a Nikon D80, which uses a CCD sensor. The basis for the CCD is the metal–oxide–semiconductor (MOS) structure, [2] with MOS capacitors being the basic building blocks of a CCD, [1] [3] and a depleted MOS structure used as the photodetector in early CCD devices.
Trickle charging is the process of charging a fully charged battery at a rate equal to its self-discharge rate, enabling the battery to remain at its fully charged level. This state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.
