    • An input device for screen navigation. The input device includes a light source for emitting light onto a surface over which the input device move, a power port for receiving electric power to operate the input device, and an optical module. The input device includes, a voltage regulator formed on a substrate for regulating the voltage of electric power to the desired level, an optical imaging module formed on the substrate for capturing successive images of the surface and producing imaging signals corresponding to the captured images, a motion determining circuit formed on the substrate for producing a motion signal of the input device based on the successive imaging signals, and a modulating circuit formed on the substrate for modulating the motion signal. The input device also includes a RF module for transforming the modulated motion signal into a RF signal to be transmitted to a receiver for screen navigation.

    • A control system for a feedback controlled LED driving circuit, which includes a valley detect regulator unit and a control and feedback unit. The valley detect regulator unit detects a sine-like DC voltage input by a rectification unit, and stores the electric energy in the storage capacitor when the input voltage is lower than a preset valley voltage. The stored electric energy converted into the system required voltage by a system power supply unit. The control and feedback unit electrically connect to the feedback controlled LED driving circuit, providing PFC, step dimming or color temperature adjustment for driving the LED light-emitting element and detecting a feedback signal of the LED driver circuit for controlling an output current of the LED driver circuit or providing protective measures.
