摘要： A method is disclosed of controlling a LED, comprising driving the LED with a DC current for a first time, interrupting the DC current for a second time such that the first time and the second time sum to a period, determining at least one characteristic of the LED whilst the DC current is interrupted, and controlling the DC current during a subsequent period in dependence on the at least one characteristic. The invention thus benefits from the simplicity of DC operation. By operating at the LED in a DC mode, rather than say in a PWM mode, the requirement to be able to adjust the duty cycle is avoided. By including interruptions to the DC current, it is possible to utilise the LED itself to act as a sensor in order to determine a characteristic of the LED. The need for additional sensors is thereby avoided.

摘要： The invention is directed to a method for controlling a deceleration process of a DC motor (20), wherein the DC motor (20) is driven by a bridge driver (18) coupled to a power supply (12) intended to provide a supply voltage VDD at a power supply output (14), the method comprising the following steps: applying a deceleration PWM signal to the bridge driver (18) for decelerating the DC motor (20), and controlling the bridge driver (18) such that a motor-induced back current is reduced, if the voltage at the power supply output (14) exceeds a voltage threshold which is higher than VDD. In accordance with the invention the step of controlling the bridge driver (18) such that a motor-induced back current is reduced, if the voltage at the power supply output (14) exceeds a voltage threshold which is higher than VDD comprises: if the voltage at the power supply output exceeds the voltage threshold, changing stepwise the pulse width of the deceleration PWM signal in a first direction until the voltage at the power supply (14) output reaches or falls below the voltage threshold, and then, if the voltage at the power supply output (14) has fallen below the voltage threshold, changing stepwise the pulse width of the deceleration PWM signal in a second direction opposite to the first direction until the voltage at the power supply output (14) again reaches or exceeds the voltage threshold. The invention is also directed to a controller suitable to carry out the above method.

摘要： Method and apparatus for controlling the rotation velocity of an optical disc in a wide range of velocities, including low velocities. In a first range of velocities, a first sensor, for example an EMF sensor, is used to control the commutation moments of a turntable motor. For velocities outside the first range, a periodic control signal based on a periodic second signal generated by a second sensor and a mapping between the first and second periodic signal are used. The method and the apparatus are suitable for LightScribe™ applications.
