Abstract: A bladed chassis system facilitates installation of the bladed chassis system and replacement of the blades at the chassis. For example, a front panel of the blade can be opened either upwardly or downwardly at the discretion of the user. Blades can be inserted and removed from the front and/or the rear of the bladed chassis system at the discretion of the user. Cables can be routed to the rear of the chassis system from either of two sides at the discretion of the user. The blades carried by the chassis have fiber management trays that can be rotationally oriented in any desired rotational position at the discretion of the user.

Abstract: An electric motor, drive, and assembly for a tracked vehicle. The assembly including an electric motor, a cylindrical housing encircling the electric motor and adapted for rotation about the motor, and a drive sprocket. The drive sprocket is coupled to the housing and having teeth to generally engage a track of the tracked vehicle.

Abstract: An integrated air jack assembly for a snowmobile for generally lifting the snowmobile from a stuck position to a free position. The assembly including a pair of airbags positioned on an underside of a chassis and coupled to an air source for inflation. In the preferred configuration of the device, the air source is a jet powered fan configured to inflate a first airbag and a second airbag for raising an underside of a chassis of the snowmobile.

Abstract: A system for inspection of the undercarriage of a vehicle. The system may comprise a mobile unit or a stationary unit configured to fit in a space below the vehicle for gathering and transmitting data, images and or recordings, of the undercarriage of the vehicle. The system comprises at least one camera and preferably a plurality of cameras and at least one light source and preferably a plurality of light sources mounted on a device configured to fit in the space below a vehicle without hindering the inspection of the undercarriage of the vehicle. Photoelectric lasers or laser scanning systems may also be incorporated into the device. Data gathered by the cameras and/or laser systems can be transmitted to a controller and in some embodiments compared to standard data for recognition and potentially warning of an unexpected condition of the undercarriage without requiring physical human inspection.

Abstract: A clutch includes a stationary sheave, a cam attached to the stationary sheave, and a movable sheave that is axially movable relative to the stationary sheave along the cam. A thrust bearing includes an outer race and an inner race, wherein the outer race is attached to the cam. A first radial spring includes a radially outward annular portion and an radially inward finger portion, wherein the radially outward annular portion is mounted on the movable sheave and wherein the radially inward finger portion bears against the inner race. In another aspect, a clutch includes a stationary sheave, a cam attached to the stationary sheave, and a movable sheave that is axially and rotationally movable relative to the stationary sheave along the cam.
