摘要： Various lens barrels and lenses are provided which may be used in miniature cameras. In one example, a lens barrel assembly includes a substantially cylindrical lens barrel with a first end including a first aperture and a second end including a second aperture. The first end further includes a first substantially annular portion having a first diameter and a first external surface. The first end also includes a second substantially annular portion having a second diameter and a second external surface. The second diameter is smaller than the first diameter and greater than a diameter of the first aperture. The first external surface of the first substantially annular portion is recessed in relation to the second external surface of the second substantially annular portion. The lens barrel assembly may also include a lens having a portion that protrudes from the second aperture of the second end of the housing.

摘要： Systems and techniques for improved lens barrel tolerance in optical systems. In some embodiments, a lens barrel has a first end section configured to position a first lens with a first diameter and a second section configured to position a second lens with a second larger diameter. The first end section of the lens barrel may include an inner mating section configured to position the first lens and an outer thread section. One of more portions of the inner mating section and associated portions of the outer thread section may be separated by a gap.

摘要： A method and system for mitigating undesirable motion of the optics of a camera are disclosed. The system can include a stage and snubber assembly for defining motion of the camera optics. The stage and snubber assembly can include a stage assembly having a stage to which the optics are attachable, at least one wing formed upon the stage, and a snubber assembly configured to cooperate with the wing(s) so as to limit motion of the stage substantially to the desired direction of travel of the camera optics.

摘要： A self-retaining ball-worm and gear mechanism is provided to facilitate the rotational transmission of motion between two orthogonal but non-intersecting axes. A circuit of balls introduced as rolling elements indirectly couples the worm and gear, and eliminates the sliding friction characteristic of classical worm and gear mechanisms. The mechanism comprises a ball-worm (200), gear (202), and axial supports or housing (204). The ball-worm defines the ball circulation path. The worm helix is designed to retaining the balls such that no additional ball-retaining components are necessary. Magnetism may optionally or additionally be employed to attract the metal balls to the worm body, further enhancing ball self-retention. The gear comprises a plurality of grooves designed to engage the helix of balls on the worm. The path of the worm helix is mathematically accurate so that balls simultaneously engage multiple gear grooves, increasing the torque load capabilities of the device.
摘要翻译：提供自保持球形蜗杆和齿轮机构以便于在两个正交但不相交的轴之间的运动的旋转传递。作为滚动元件引入的滚珠电路间接耦合蜗轮和齿轮，消除了经典蜗杆和齿轮机构的滑动摩擦特性。该机构包括球形蜗杆（200），齿轮（202）和轴向支撑件或壳体（204）。滚珠蜗杆定义了球的循环路径。蜗杆螺旋被设计成保持球，使得不需要额外的球保持部件。可以任选地或另外地使用磁性来将金属球吸引到蜗杆体，进一步增强球自身保持力。齿轮包括设计成接合蜗杆上的球的螺旋的多个凹槽。蜗杆螺旋的路径在数学上是准确的，使得球同时接合多个齿轮槽，增加了设备的扭矩负载能力。
