Abstract: Techniques for enhancing the use of a motion capture system are provided. A motion capture system tracks movement and audio inputs from a person in a physical space, and provides the inputs to an application, which displays a virtual space on a display. Bodily movements can be used to define traits of an avatar in the virtual space. The person can be directed to perform the movements by a coaching avatar, or visual or audio cues in the virtual space. The application can respond to the detected movements and voice commands or voice volume of the person to define avatar traits and initiate pre-scripted audio-visual events in the virtual space to provide an entertaining experience. A performance in the virtual space can be captured and played back with automatic modifications, such as alterations to the avatar's voice or appearance, or modifications made by another person.

Abstract: Device for manoeuvring a tension wheel in a chassis of a tracked vehicle, in which the tension wheel is rotatably mounted on a telescopic rocker arm (12). The rocker arm can, on the one hand, be lengthened and shortened by a first hydraulic cylinder and, on the other hand, swivelled about a transverse axis (14) by a second hydraulic cylinder for the purpose of raising and lowering the tension wheel. The first hydraulic cylinder is designed to act upon a lever arm (58) of a sleeve (54) rotatable in a hub part (20) of an inner part (18) of the rocker arm (12), which sleeve has an eccentrically mounted crank pin (52) which is hinge-connected to an outer part (22) of the rocker arm for the purpose of displacing the latter relative to the inner arm part, in the event of a mutual rotation motion between the sleeve (54) and the hub part (20) of the inner rocker arm part, in such a way that the rocker arm is lengthened upon a downward swivel motion of the arm and the tension wheel.

Abstract: An axle mount device for mounting an axle to a snowmobile track suspension frame has a base portion and an adjuster portion. The base portion has an axis and a bore coincident with the axis. The adjuster portion is secured to the base portion asymmetrically with respect to the axis, and engages an opening in the frame. The axle mount may be moved between first and second positions to vary a position of the axle with respect to the frame.

Abstract: A shock absorbing, tracked wheel assembly of an off-road vehicle has a set f spoke-like structures radiating from the assembly's center or spider. The spoke-like structures include cylinders affixed to the spider and pistons axially translatable in the cylinders. The pistons are biased radially outward by coil springs in the cylinders. The springs' action is dampened by a flow restrictive collar girding the piston and separating fluid in the cylinder into separate chambers. Struts extend from the pistons and the struts have track engagement shoes on their outer ends. The shoes have a generally arcuate sector that engages a track or band in tractive contact with the ground. Rotating the struts about their longitudinal axis will vary the distance between the cylinder and the track shoe so that tension on the track can be adjusted. Sufficient strut rotation allows the track to be removed from the assembly for purposes of track repair or replacement.
