Abstract: A computer mouse having a unique identification that uniquely identifies the computer mouse and is readable by a computer to which the mouse is coupled. The computer mouse is provided with a processor, a memory and a mouse interface and may be used for controlling data transfer between the mouse and a computer to which it is coupled, by receiving from the computer a data transfer request and using the mouse interface to authorize the data transfer request. The mouse may be used to provide personal and secure control of an application that is distributed between the mouse and the computer so as to allow use of the mouse to control a software application running on the computer and at the same time to allow the computer to control the behavior of the mouse by interacting with software run thereby.

Abstract: A built-in auto-tuning system of a motor control system provides an auto-tuning of the motor control system. The built-in tuning system generates and applies a random noise test signal to the controller. In response to the test signals, the tuning system obtains response data such as the gains and phases over a wide range of operating frequencies. Based on the received data, the tuning system generates an open-loop Bode plot of the control system. The tuning system then calculates the phase and gain margins of the control system. The calculated gain and phase margins are compared with a set of predetermined values by the tuning system to automatically adjust the compensation parameters of the motor control system for a stable operation.
