Abstract: The present invention relates to a multi-modes heat exchanger and air ventilation system and method. The system's different modes are possible with the rotation of fan assemblies allowing airflow into specific ducts, thus acting both as fans and as valves. Each air handing unit is connected to a centralized network which allows the control of multiple units simultaneously in response to interior or exterior air characteristics.

Abstract: A track assembly for providing traction to an all-terrain vehicle (ATV) or other tracked vehicle. The track assembly may comprise a wheel device for contacting an inner side of an endless track such that a longitudinal end segment of the endless track turns around the wheel device. The wheel device allows a change in curvature of the longitudinal end segment of the endless track when the longitudinal end segment of the endless track contacts an obstacle on the ground. In some embodiments, the wheel device may comprise a resilient wheel that is elastically deformable. In other embodiments, the wheel device may comprise a wheel carrier carrying a plurality of carried wheels.

Abstract: There is described a method for simulating an imaging process for an organ, the method comprising: retrieving from a memory a 3D volume model of the organ, the 3D volume model describing a 3D structure of the organ and a distribution of density within the 3D structure, the 3D structure representing a surface and internal features of the organ; generating a slice of the 3D model according to a position and an orientation of an imaging device, the slice including a cross-section of the surface and the internal features; rendering an image in accordance with the slice; and displaying the image.

Abstract: An endless track for providing traction to a snowmobile is provided. The endless track comprises an elastomeric body comprising an inner side for facing a plurality of wheels of the snowmobile and a ground-engaging outer side for engaging the ground. The endless track also comprises a plurality of elastomeric fraction projections on the ground-engaging outer side. The endless track is free of transversal reinforcing rods extending transversally to a longitudinal direction of the endless track. When the snowmobile is operated at a given speed, less noise is generated than if the endless track had transversal reinforcing rods embedded in the elastomeric body where respective ones of the elastomeric traction projections are located but was otherwise identical.
