The present invention provides a board mountable system for filming underwater video. The inventive board mountable system can be mounted to the underside of water vehicles for incorporating a camera for filming from an underwater perspective. The inventive board mountable system is shaped to minimize drag as a result of the mounted camera or camera system. Embodiments of the inventive system includes a fin shaped housing for holding a camera or camera system. In certain embodiments, the fin is removably attached to the water vehicle, such as a surf board, where the fin housing can be swapped with other fins being used with the water vehicle for controlling the direction of a watersports board in motion. These embodiments of the inventive system further include a connection means for connecting the fin to the underside of a water vessel.

An aperture unit includes a base plate, a cover, a plurality of aperture blades, a drive ring, and protrusions. The aperture blades are disposed between the base plate and the cover, and adjust the amount of light passing through by varying the size of an opening. The drive ring is disposed between the base plate and the cover, and is rotationally driven when the aperture blades are opened and closed. The protrusions are provided to the drive ring and the cover, respectively, and support the aperture blades in the direction of suppressing upward warpage of the aperture blades in a state in which the aperture blades move in the direction of reducing the size of the opening.

A lens driving device is describes that includes a stator and a mover, with a lens support for supporting the lens and for moving in an optical axis direction of the lens with respect to the stator. Any one of the stator and the mover has protruding portions and any other one of the stator and the mover has recessed portions into which the protruding portions are inserted. The protruding portions and the recessed portions each have opposing surfaces where the protruding portions and the recessed portions are opposed to each other, and a resin with viscoelasticity is provided to contact the opposing surfaces of the protruding portions and the opposing surfaces of the recessed portions.

To easily specify the position of a defect in a separator, a method for producing a separator original sheet (12b) includes the steps of: forming a separator original sheet (12b) including a separator original sheet (12c) and a heat-resistant layer coated on the separator original sheet (12c); detecting a defect (D) in the separator original sheet (12b); and recording information including information on a position of the defect (D) which position is a position in the width direction of the separator original sheet (12b).

A camera protection device, a protected camera and a vehicle having a protected camera, all include a weatherproof housing having a lower portion for holding a camera and an upper portion, a movable protective domed cover, and a mechanism for selectively moving the domed cover in front of the lower portion in a closed position or above the lower portion in an open position. The mechanism includes a motor that is operatively connected to the domed cover. A cleaning brush vertically wipes across the lower portion when the mechanism moves the domed cover. A seal seals between the domed cover and the lower portion when the domed portion is in front of the lower portion in a closed position. The mechanism includes a cable, a pivot for pivoting the domed cover, and a linkage connecting the motor to the domed cover. A belt operatively connects the motor to the linkage.

A driving apparatus includes a driving source supplied with a power and configured to generate a driving force, a first cam member configured to rotate in a first rotational direction in accordance with the driving force from the driving source, a driving member configured to drive a driven member as the first cam member rotates, and a second cam member configured to contact the driving member after an electrification to the driving source is stopped so as to rotate the first cam member in a second rotational direction opposite to the first rotational direction.

An image photographing system for viewing 3D images with naked eyes and using method thereof, including an L-shaped frame (1), wherein, a top end of a vertical portion of the L-shaped frame successively at equal intervals providing with: an intermediate photographing mechanism, a left photographing mechanism and a right photographing mechanism, a left driving mechanism and a right driving mechanism, a guide post, a vertical driving servo motor, a driving lead screw; a support plate drives the left driving mechanism and the right driving mechanism to move up and down by moving up and down along the guide post under the drive of the driving lead screw, so as to drive the left photographing mechanism or the right photographing mechanism to swing up and down. The present invention can see the realistic and natural 3D images with naked eyes.
