    摘要: A noise compensating device in a discrete time control system, such as a R/W system for hard disks, including: a control loop generating a first timing signal, a signal indicative of a quantity to be controlled, and a control signal, which have a first frequency; and an open loop control line which generates a compensation signal synchronous with the control signal and includes a sensor. The sensor includes a sensing element, generating an analog signal, an acquisition stage, connected to the sensing element and generating a disturbance measure signal correlated to the analog signal and synchronous with the control signal, and a synchronization stage. The synchronization stage includes a frequency generator having an input receiving the first timing signal and a first and a second output connected to the acquisition stage and generating, respectively, a second timing signal and a third timing signal.

    摘要: A user controlled device, movable into a plurality of positions of a three-dimensional space, includes a MEMS acceleration sensor to detect 3D movements of the user controlled device. The device, such as a mouse, sends control signals correlated to the detected positions to an electrical appliance, such as a computer system. A microcontroller processes the output signals of the MEMS acceleration sensor to generate the control signals, such as screen pointer position signals and “clicking” functions.
