Abstract: An automatic assembling system and method for camera lens units are provided. The system includes a main workstation, a barrel-feeding station, a lens-feeding station, and a camera lens-removing station. The method includes (A) operating a plurality of barrel-clamping units of the main workstation cyclically and intermittently along a feeding direction; (B) moving a plurality of barrels from a barrel standby area of the barrel-feeding station onto the barrel-clamping units in sequence; (C) moving a plurality of lens units from a lens standby area assembly of the lens-feeding station into the barrels to form the camera lens units; and (D) moving the camera lens units from the barrel-clamping units into a camera lens-collecting area of the camera lens-removing station. The steps (B, C, D) are performed in cooperation with the intermittent operations of the barrel-clamping units.

Abstract: A high precision molding device for insert-molding optical lens comprises a stationary sub-mould and a movable sub-mould for engaging with the stationary sub-mould thereby forming a mould cavity therebetween for molding an optical lens. The molded lens has a body and a protection ring extending outside from the body, and is separated from the stationary sub-mould together with the movable sub-mould. The movable sub-mould includes a mould base, a core fixed with the mould base and a pushing means for pushing the molded lens off the movable sub-mould. The pushing means is circumferentially positioned at the mould base. The upper and bottom surfaces of the protection ring of the molded lens form textures to be foggy.

Abstract: A linear voltage regulator, such as a low-dropout regulator, supplies power to one or more digital circuits within a computer system. The low-dropout regulator provides a substantially constant output voltage independent of loading conditions. The low-dropout regulator is biased at a relatively low operating current for steady-state operation to improve power efficiency of the low-dropout regulator. During a loading condition change, an adaptive biasing circuit senses the loading condition change and provides additional biasing current to momentarily increase the operating current of the low-dropout regulator to improve transient response.
