The three-coordinate mapper and the mapping method has high measurement precision and fast measurement speed.

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).

Provided is a vibration wave motor including: a vibrator; a friction member; a pressurizing mechanism; a first holding mechanism; and a second holding mechanism, wherein the vibrator and the friction member are configured to perform relative movement with respect to each other, wherein the first holding mechanism includes a first holding portion and a second holding portion which is longer than the first holding portion in a direction of the relative movement, wherein the friction member is arranged between the first holding portion and the second holding portion, wherein the first holding portion includes a first restriction portion, wherein the second holding portion includes a second restriction portion, and wherein the first restriction portion and the second restriction portion are brought into abutment against the second holding mechanism to restrict movement in directions other than the direction of the relative movement of the vibrator and the first holding mechanism.

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.
