Abstract: The present invention relates to a powered surgical tool that selectively rotates a tool head (effector) to effect tissue modification during a surgical procedure, and allows for use also as a fastener driver by a simple change of end effectors and shifting a drive selector.

Abstract: An oscillating drive mechanism for a surgical tool includes a motor having a rotor, a crank assembly hub, a link secured to the crank assembly hub, a pivot shaft, a shuttle including an arcuate rack gear secured to the link so that rotation of the crank assembly hub provides reciprocating rotary motion to the arcuate rack gear about the pivot shaft. A gear is meshed with the arcuate rack gear and is secured to an output shaft, whereby rotational motion of the motor induces rotary oscillating motion to the output shaft.

Abstract: A bone, cartilage, and disk removal tool assembly is provided with a motor mounted in a housing. A spindle is mounted for rotation to the housing. A rack-and-pinion mechanism is operably driven by the motor and connected to the spindle to oscillate the spindle for providing a rotary oscillating cutting operation. According to at least another embodiment, a plurality of cams is supported in the housing and driven for rotation by the motor. A plurality of followers is mounted for rotation to the housing, in engagement with the plurality of cams so that one rotation of the plurality of cams oscillates the plurality of followers more than once while preventing over-rotation of the plurality of followers. A peak angular acceleration of the spindle is less than nine million radians per second squared.

Abstract: A displaceable speaker assembly for a vehicle includes a housing, a speaker array rotatably coupled to the housing and including a plurality of electro-acoustic transducers (e.g., twiddlers), a drive unit coupled to the housing, and a lever assembly coupling the drive unit to the speaker array. The drive unit is operable to drive motion of the lever assembly, which, in turn, drives rotation of the speaker array relative to the housing.

Abstract: A sliding vehicle window assembly which includes at least one, and preferably a pair, of window panels spaced from each other to define a window opening and interconnected by upper and lower frame members or tracks, bonded to the interior surface of the pair of window panels. The upper and lower frame members are also spaced vertically apart from each other. At least one, and preferably two, arcuate channels are defined in each of the inwardly facing walls of the two frame members--the two channels arranged generally in tandem or end-to-end alignment. The pair of channels in each frame member are configured to receive a window panel, opposite ends of which retain cam or channel followers received by the channels. A latch handle interconnects one end of each cam follower and includes a cam projection also received in the channel and when rotated in one end of the channels, moves the sliding window generally perpendicularly with respect to the window opening when the window is located over the window opening.
