摘要： A motor control system accurately and reliably controls the speed of a motor so that the motor operates in accordance with a predetermined motor speed profile, and therefore does not exceed a predetermined safe speed, decelerates at a controlled rate, maintains a safe minimum speed, and does not turn in reverse. If the motor operates out of these limits, a malfunction is indicated and the control system halts operation of the motor. The motor speed is determined using an electronic tachometer that analyzes the current in at least two phases of the motor to provide extremely precise and reliable velocity information for the motor.

摘要： There is provided a method for use by a content navigation module for managing delivery of content. The method comprising communicating an identifier contained in the content navigation module with a first computing device to enable the first computing device to receive a selected content from a presentation server over a network; receiving a delivery progress of the selected content from the first computing device periodically; storing the delivery progress of the selected content; losing communication with the first computing device after storing the delivery progress; and communicating the identifier contained in the content navigation module and the delivery progress of the selected content with a second computing device to enable the second computing device to resume receiving the selected content from the server over the network according to the delivery progress of the selected content stored in the content navigation module.
