Systems and methods are disclosed for controlling a torque output of a motorgenerator via one or more torque commands generated by a controller. The arithmetic unit includes a multiply adder and a non-restoring divider. These methods and systems may comprise capturing an image of a document using a mobile communication device; transmitting the image to a server; and processing the image to create a bi-tonal image of the document for data extraction. Topical leads, percutaneous leads, subcutaneous leads, intraosseous leads, or leads can be placed in proximity to the operative field corresponding to the prosthetic component installation. The encoding methods are essentially based on block-based motion estimation and grouping of motion estimations of various video frames. The securing and releasing of the longitudinal and vertical adjustments takes place via a cam disc actuatable by the operating lever.
