A powered running board assembly has a deck and at least two hinges extending from the deck for mounting longitudinally the deck to an underside of a vehicle. Each hinge has a mounting bracket configured to mount to the underside of the vehicle. A pair of links pivotally extending between the deck and mounting bracket. The deck is movable between a retracted position and an extended position. A linear drive assembly operably engages at least one of the hinges to drive the deck between the retracted and extended positions. The linear drive assembly operably extends between opposite pivots of the pair of links. As the drive extends and retracts, the pair of links is expanded and contracted effecting the desired movement of the running board between inboard and outboard positions.

Angular rate sensor for detecting rotation about first, second and third mutually perpendicular input axes having a plurality of generally planar proof masses coupled together for linear drive-mode oscillation along multi-directional drive axes in a plane formed by the first and second input axes. The masses are mounted on a generally planar sense frame for linear movements relative to the sense frame in drive-mode and for rotation together with the sense frame in sense modes. The sense frame is mounted for rotation with the masses in sense modes about the first, second, and third input axes independent of each other, in response to Coriolis forces produced by rotation of the masses about the first, second, and third input axes respectively. And capacitance sensors responsive to the rotational movements of the masses and the sense frame in sense modes are employed for monitoring rate of rotation.

A driving mechanism includes: a fixed base member; a movable base member which is moved relative to the fixed base member; and at least three driving devices each having an operating part which is moved linearly, wherein the three driving devices are loaded on either one of the fixed base member and the movable base member, at least three operated parts are formed on the other one of the fixed base member and the movable base member where the driving devices are not loaded, driving forces from the operating parts of the driving devices are acted on the at least three operated parts, respectively. The operated parts each has a moving guide part extending in a direction of a guide axis orthogonal a linear driving axis along which the corresponding operating part of the driving device is moved. The operating parts are guided in the respective corresponding moving guide parts to cause relative rotation of one of the movable base member and the fixed base member against the other. At least one of the linear driving axes extends in a first direction, the other linear driving axis extends in a second direction orthogonal to the first direction, and the respective linear driving axes extend in tangential directions of a circle having an arbitrary point on the movable base member or the fixed base member as a center point. The respective guide axes extend in radial directions with respect to the center point

The invention relates to a method and apparatus for forming metal containers. The method involves introducing a knockout element (110) into the container body through the open end, providing a forming die shaped to reduce the diameter of the sidewall of the container body (100) when the open end of the container body (106) is forced therein to produce a neck portion of reduced diameter on the container body, driving the open end of the container body into the forming die (108), retracting the knockout element through the neck portion as the neck portion is formed, and removing the container body (106) from the forming die (108) and knockout element (110). In the invention, the driving of the open end of the container body into the forming die and / or the movements of the knockout element are carried out under computer numerical control, preferably employing linear motor drives, thereby enabling the driving or movement to be optimized for the container body and the neck portion formed thereon.
