Methods and systems for provisioning online services are described. The images can then be integrated into composite images for browsing to simulate viewing an item, such as a biological sample, under a microscope. A first brake system is selectively operable to rotationally lock an output ring gear of the planetary gear system, and a second brake system is selectively operable to rotationally lock the planet carrier of the planetary gear system. The server may associate the received machine fingerprint with the appropriate online account information received from a host server or the like. The serial bus control scheme allows for information to be written to or read from individual regulators or be written to read from all regulators that are coupled to the master controller.
