An automatic transmission is provided with a brake device provided with a rotatable rotation-side friction plate and a non-rotatable fixed-side friction plate; a transmission case which accommodates the brake device; a lubrication oil supply section which supplies lubrication oil introduced into the transmission case to an upper portion of the brake device; and a lubrication oil discharge section disposed below the brake device, and configured to discharge lubrication oil supplied from the lubrication oil supply section to the brake device.

Device and method for providing rotational power using power transmission are disclosed. The device enables multi-dimensional and angle-agnostic displacement of the rotational power output with respect to the input location and transference of high-torque and high-speed rotational movement, while preserving maximal efficiency and quick response. The device is a transmission gear that comprises at least two gear-links in a multi-link articulated gear (MLAG). Each of the links comprising at least two gear wheels. The transmission gear further comprising a common axis adapted to allow the links to rotate freely with respect to each other about the common axis and thus to allow change of the angle between the at least two links and thereby to change the distance between the input shaft and the output shaft.

Embodiments of the present invention provide a camera cleaning apparatus. According to one embodiment, a first disc coupled to a first rod, a camera mounted to a portion of the first disc; a second disc coupled to a second rod, wherein a first portion of the first rod is situated inside the second rod and the first rod rotates independently of the second rod; a first and a second directional sensor operatively coupled to the first disc; a first motor mechanically connected to a first rod; a protective cover mounted between the first and the second disc; and a cleaning mechanism mechanically coupled to the second disc and an attachment point disposed on a portion of the protective cover is provided. Embodiments of the present invention can be utilized to clean a protective cover that encapsulates the camera without obscuring the camera's field of view.

A support assembly for coupling a first gearbox to an airframe of an aircraft. The first gearbox has an output gear operable to transfer torque to an input gear of a second gearbox via a common shaft rotatable about a longitudinal axis. The support assembly includes a fixed joint proximate the longitudinal axis. A first directional reacting joint remote from the longitudinal axis provides a first radial growth degree of freedom to the first gearbox relative to the longitudinal axis. A second directional reacting joint remote from the longitudinal axis provides a second radial growth degree of freedom to the first gearbox relative to the longitudinal axis. The first radial growth degree of freedom is not parallel with the second radial growth degree of freedom such that the support assembly maintains the output gear of the first gearbox in substantial collinear alignment with the input gear of the second gearbox.

Electric motors are disclosed. The motors are preferably for use in an automated vehicle, although any one or more of a variety of motor uses are suitable. The motors include lift, turntable, and locomotion motors.
