Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: An annotation sharing system includes an annotation database and an annotation management server. The annotation database stores electronic annotation files. Each electronic annotation file associated with a note author identification and an electronic book identification, and includes data entries of various data types. The annotation management server displays the electronic annotation files together with the associated note author identifications and relevant information of the electronic books to a client device, and receives a download request for the electronic annotation files from the client device. The annotation management server provides a first graphical user interface to the client device for displaying the electronic annotation file with the associated electronic book file, and each data entry in the electronic annotation files is represented with a customized visual cue.

Abstract: A camera module (200) includes a lens module and a base (210) with a sensor installed thereon. The base is provided with at least two supporting protrusions (222) extending therefrom. Each protrusion is oriented the lens module, and the lens module is fixedly to and contacts with the at least two supporting protrusions. A colloid layer surrounding the sensor is sandwiched between the second end of the holder and the base. Electronic components are disposed on the circuit board and covered by the colloid layer.

Abstract: A camera module (200) includes a lens barrel (202), at least one lens (204), a holder (206), and a base (210). The at least one lens is received in the lens barrel. The holder has a first end (212) and a second end (214). The holder further has a cavity (216) defined through the first end and the second end thereof. The first end holds the lens barrel. The second end is provided with at least two supporting protrusions (222) extending therefrom along a direction away from the first end of the holder. The base fixedly contacts with the at least two supporting protrusions. A method for assembling a camera module is also provided.

Abstract: An image sensor package includes a printed circuit board (PCB) with a plurality of signal input pads disposed on an upper surface thereof, an image sensor chip, a frame layer, a transparent layer, a plurality of wires and glue. The image sensor chip includes a photosensitive region formed on a top surface thereof, a plurality of bonding pads formed on the periphery thereof, and a carrying region formed between the photosensitive region and the bonding pads. The glue covers a space formed between the PCB, the image sensor chip and the frame layer, for sealing the bonding pads, the input pads and the wires. The frame layer defines a base adhered to the corresponding carrying region and a window corresponding to the photosensitive region. The transparent layer is adhered to cover the window of the frame layer to seal the photosensitive region of the image sensor chip.

Abstract: An exemplary camera module includes a lens holder, a lens module, a lens module, an image sensor chip, and an attaching member. The lens module is received in the lens holder. The lens module comprises a barrel and at least one lens received in the barrel. The image sensor chip comprises a photosensitive area configured for receiving light transmitted through the lens module. The attaching member is disposed at an end portion of the lens holder opposite to the lens module. The attaching member is configured for attaching the lens holder to the image sensor chip. The attaching member defines a light transmittance space configured for exposing the photosensitive area to the lens module.
