    摘要: In accordance with an example embodiment, a mower-conditioner may include first and second conditioning rolls, at least one eccentric assembly, and a linkage. The first and second conditioning rolls are spaced apart a distance. The at least one eccentric assembly is coupled to the mower-conditioner. The linkage is coupled between the eccentric assembly and the first conditioning roll. The movement of the at least one eccentric assembly causes the first conditioning roll to move via the linkage, which adjusts the distance between the first and second conditioning rolls.

    摘要: The gears for reversing the rowing motion for oars is a gearing mechanism configured for use with an oar. The gears for reversing the rowing motion for oars reverses the pulling motion associated with the oar. This reversal of the pulling motion allows the oar to be used normally while the rower faces the bow of a boat. The gears for reversing the rowing motion for oars comprises a drive gear mechanism, a rotation gear mechanism a handle mechanism, an oar mechanism, and a gunwale mount. The drive gear mechanism transfers power from the handle mechanism to the oar mechanism. The gunwale mount attaches the gears for reversing the rowing motion for oars to the gunwale of a boat. The rotation gear mechanism raises and lowers the oar into the water.

    摘要: A flexure-based micro-array having a plurality of micro-assemblies, each comprising: an object; and at least three electrostatic actuation modules for tipping, tilting, and/or piston-actuating the object, each actuation module comprising: a base with first and second electrodes electrically isolated from each other; an electrically conductive lever arm; a first flexure bearing suspending the lever arm adjacent the first and second electrodes so that electrical activation of at least one of the first and second electrodes produces an electrostatic moment of force on the lever arm to resiliently bias the first flexure bearing and pivot the lever arm about a fulcrum; and a second flexure bearing connecting the lever arm to the object at a connection location that is different from other connection locations of the other actuation modules so that pivoting the lever arm about the fulcrum induces the second flexure bearing to pivot the object about an object pivot axis defined between two of the other connection locations while the second flexure bearing decouples the lever arm from object displacements induced by two of the other actuation modules connected to the two other connection locations defining the object pivot axis, wherein the plurality of micro-assemblies are arranged with the objects juxtaposed in a substantially 2D array.

    摘要: A bending operation system includes an elongated tubular portion including a bending portion, a first linear member and a second linear member which cause the bending portion to bend, and a drive portion which displaces the first linear member and the second linear member. The bending operation system further includes a first displacement detector which acquires a displacement of the first linear member as a first displacement, a second displacement detector which acquires a displacement of the second linear member as a second displacement, and a calculator which calculates operation assist information by use of one or both of the first displacement and the second displacement.

    摘要: A wheel lock configured for use in a movable apparatus is disclosed herein. In various embodiments, the movable apparatus can include a leg structure and a wheel rotatably mounted with respect to the leg structure. A wheel lock can extend through the wheel. The lock can have a first position in which the lock prevents rotation of the wheel from rotating and a second position in which the lock does not prevent rotation of the wheel. The second position can be axially displaced relative to the first position.
