Abstract: A control method of a driving mechanism is provided, including: the driving mechanism provides a first electrical signal from a control assembly to the driving mechanism to move the movable portion into an initial position relative to the fixed portion, wherein the control assembly includes a control unit and a position sensing unit; the status signal of an inertia sensing unit is read; the control unit sends the status signal to the control unit to calculate a target position; the control unit provides a second electrical signal to the driving assembly according to the target position for driving the driving assembly; a position signal is sent from the position sensing unit to the control unit; the control unit provides a third electric signal to the driving assembly to drive the driving assembly according the position signal.

Abstract: A system and method for restricting and controlling access to electronic devices, the system includes a database of workers, a fool-proofing unit, and a controlling unit. The fool-proofing unit includes an information input module collecting information as to an electronic device and identity and extent of authority of a worker requesting to use such electronic device. A query module to search the database is also included, the query module can determine whether the worker has the authority to sign in to use a certain electronic device. The controlling unit can power on the electronic device when a given worker with necessary authority signs in to use the electronic device. The method is also disclosed.
