| 20110083952 | KEY ASSEMBLY USED IN AN ELECTRONIC DEVICE - A key assembly used in an electronic device includes a printed circuit board (PCB) including two optical couplers, a key body and a supporting assembly. The key body is rotatably supported on the PCB and includes a circular disk and a plurality of teeth. The plurality of teeth extend from periphery edge of the circular disk toward the PCB and are spaced apart from each other. The supporting assembly supports the key body on the PCB. When the key body is rotated, the plurality of teeth interact with the two optical couplers to generate one or more control signals to control corresponding one or more operations of the electronic device. | 04-14-2011 |
| 20110133701 | DUAL-MODE CHARGER CIRCUIT - A dual-mode charger circuit includes a first charge circuit and a second charge circuit connected in parallel between a power source and a battery, to charge the battery under a slow charge mode and a quick charge mode. A central processing unit detects a capacity of the battery and determines whether the detected capacity exceeds a predetermined capacity, and outputs a mode control signal according to the determination. A mode switch circuit switches the second charger circuit on/off according to the mode control signal. When the second charge circuit is off, the battery is charged under the slow charge mode, and when the second charge circuit is on, the battery is charged under the quick charge mode. | 06-09-2011 |

| 20090009986 | Headlamp That may Be Dismantled - This invention relates to an illuminating tool and particularly to a headlamp that may be worn on a human head for use and may be dismantled. In a skill of this invention, the headlamp that may be dismantled comprises a fixture with a head strap, and a floodlight. The floodlight comprises a lamp body and a lamp receptacle, being characterized in that the head body and lamp receptacle of the floodlight is an all-in-one unit. The fixture mount may be dismantled from the floodlight or inserted to match with each other. In the manner, the floodlight may be taken apart from the fixture mount to serve as an ordinary flashlight for an extra use of the headlamp. | 01-08-2009 |

| 20100165481 | COMPACT ZOOM LENS - A zoom lens includes a substrate, an imaging unit, a stationary lens barrel, a cam lens barrel and a guide lens barrel. The substrate defines a plurality of openings thereon. The imaging unit is attached on the substrate. The stationary lens barrel is mounted on the substrate and surrounding the imaging unit. The cam lens barrel is rotatably received in the stationary lens barrel and movable along the optical axis of the zoom lens as the rotation thereof along the inner circumference of the stationary lens barrel. The guide lens barrel is received in the cam lens barrel and movable axially following the motion of the cam lens barrel, and comprises a plurality of key numbers protruding outwards from the outer circumference corresponding to and received in the openings of the substrate when the zoom lens is positioned in the minimum focal length position. | 07-01-2010 |
| 20110149414 | ZOOM LENS - A zoom lens includes a lens, a shutter-aperture, a moving barrel and a resisting ring. The lens includes a curved surface. The shutter-aperture includes a diaphragm for allowing light rays passing through and at least three blind holes. The moving barrel includes a bottom plate, a securing portion for securing the lens, at least three protrusions surrounding the securing portion and at least three elastic elements sleeved on the protrusions respectively. The securing portion and the at least three protrusions extend towards the object-side from the bottom plate. The resisting ring is disposed on an end of the moving barrel opposite to the bottom plate. The aperture-shutter is received in the moving barrel and the movement of the aperture-shutter is bounded by the resisting ring. When the zoom lens contracts, the protrusions are received in the blind holes correspondingly and the lens is received in the diaphragm. | 06-23-2011 |
