Abstract: A location engine uses the empirical measurements made by a scouting wireless terminal (i) to discover the existence of a reference radio within a geographic region; (ii) to generate an estimate of the location of the newly-discovered reference radio, and (iii) to generate an estimate of the transmission power of the downlink control channel radio signal transmitted by the newly-discovered reference radio. The location engine then uses: (i) the estimate of the location of the newly-discovered reference radio, and (ii) the estimate of the transmission power of the downlink control channel radio signal transmitted by the newly-discovered reference radio, and (iii) measurements, made by a user wireless terminal, of the power of each of the downlink control channel radio signals transmitted by each of the reference radios to generate an estimate of the location of the user wireless terminal.

Abstract: A route generator and method of operating the same including; calculating route traversal values for a plurality of blocks in a first group simultaneously, each block including a plurality of cells, traversal values being values that consider terrain movement cost data and data indicating progress towards a route endpoint on a per-cell basis, wherein the plurality of blocks are chosen such that the blocks in the first group fail to share any edges with other blocks in the first group.

Abstract: A tapered short tunnel for use on a tracked vehicle, such as a snowmobile. The tapered short tunnel has a tapered distal end having a width less than a width of an endless track used on the snowmobile. This tapered portion reduces the snowmobile from catching or grabbing snow in a snow trench, thereby enabling the snowmobile to traverse deeper snow.

Abstract: An apparatus is provided for a firearm suppressor. The apparatus includes an outer tube defining a longitudinal axis, and an inner cylinder defining an inner chamber. The inner cylinder is disposed at least partially within the outer tube and defines an outer chamber with the outer tube, where the outer chamber is disposed between an inner surface of the outer tube and an outer surface of the inner cylinder, and where the inner cylinder comprises at least one opening to fluidly couple the inner chamber with the outer chamber. The apparatus also includes at least one flow structure disposed in the outer chamber and positioned to direct firearm combustion gasses in a fluid pathway that is off-axis with respect to the longitudinal axis.

Abstract: A snowmobile has an air intake system integrated into the snowmobile body, and with air intake vents facing rearwardly towards the rider. The air intake system includes a plenum defined by a portion of the body and ducting extending within the body. The ducting is porous to allow the air input noise to be dissipated within the engine compartment. The snowmobile further comprises couplings which may be realigned to accommodate wear. A frame coupler allows multiple differently configured frame tubes to be connected to the tunnel. The chassis of the snowmobile includes a casing for receiving the gears which drive the belt.

Abstract: An exhaust system for a vehicle including a deep snow exhaust outlet defined by a driveline structural member of the vehicle. If the vehicle includes a turbo charger and an exhaust silencer, the turbocharger and the exhaust silencer are coupled together without exhaust piping therebetween.

Abstract: In one embodiment, a utility vehicle includes a plurality of ground-engaging members configured to contact a ground surface, and a powertrain assembly operably coupled to the ground-engaging members. The utility vehicle also includes a frame supported by the ground-engaging members and extending along a longitudinal axis of the utility vehicle. The utility vehicle further includes a tunnel member coupled to the frame and extending along the longitudinal axis. The tunnel member is positioned at a first height from the ground surface. Additionally, the utility vehicle includes a cargo portion supported by the frame and positioned generally rearward of the tunnel member. The cargo portion has a cargo surface substantially aligned with the tunnel member and positioned at a second height from the ground surface. The first height is approximately equal to the second height.

Abstract: The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces.

Abstract: An apparatus for ambidextrous control of a charging handle is disclosed. In certain examples, the charging handle includes an elongated shaft defining a centerline, and a handle body. In certain examples, the handle body includes a first protrusion extending transversely from the centerline to a distal end, and a second protrusion extending transversely, in an opposite direction than the first protrusion, from the centerline to a distal end. The handle body also includes a first lever pivotally coupled to the first protrusion at a pivot point adjacent the distal end of the first protrusion, the first lever configured to independently actuate a latch mechanism, and a second lever pivotally coupled to the second protrusion at a pivot point that is adjacent the distal end of the second protrusion, the second lever configured to independently actuate the latch mechanism.

Abstract: A restraint system for a utility vehicle comprising a first restraint including a first retractor coupled to the utility vehicle at a first retractor anchor point, a first webbing retractable into the first retractor and having a first end and a second end, a first latch moveably engaged with the first webbing, and a first latch receiver configured to receive the first latch, and a second restraint including a second retractor coupled to the utility vehicle at a second retractor anchor point, a second webbing extendable from and retractable into the second retractor and having a first end coupled to the second retractor and a second end, a second latch coupled to the second webbing, and a second latch receiver positioned at a second receiver anchor point and configured to receive the second latch and retain the second end of the second webbing adjacent the second receiver anchor point.

Abstract: A utility vehicle with ergonomic, safety, and maintenance features is disclosed. A vehicle is also disclosed with improved cooling, suspension and drive systems. These features enhance the utility of the vehicle.

Abstract: A Powersports vehicle is disclosed which includes a frame, ground engaging members supporting the frame, comprising at least two front wheel, and a power source for driving the front wheels. A front drive is coupled to the power source and to the front wheels, the front drive being coupled to the frame through isolation mounts to reduce vibration of the front drive through the frame.

Abstract: Systems and methods for detecting a vehicle hazardous condition of a recreational vehicle and activating a distress mode of the recreation vehicle in response to detecting the vehicle hazardous condition.

Abstract: A vehicle may include a continuously variable transmission which requires non-recycled air. The continuously variable transmission may provide non-recycled air to a first number of sheaves of the continuously variable transmission with a second number of air supply conduits, the second number being less than the first number. A cover of the continuously variable transmission may have a unitary body.

Abstract: Disclosed is a linear voltage regulator with an input terminal, an output terminal, a pass device electrically connected to the input terminal and the output terminal, and an error amplifier that controls the output voltage at the output terminal by controlling the voltage drop across the pass device. The disclosed linear voltage regulator includes a light emitting section electrically connected in series with the pass device between the input terminal and the output terminal and a photovoltaic section, electrically connected to the output terminal, that receives photons emitted by the light emitting section and outputs a current to output terminal. The disclosed linear voltage regulator is more efficient than conventional linear voltage regulators because, unlike in those convention linear voltage regulators, the voltage drop across the pass device is only a fraction of the total potential difference between the input terminal and the output terminal.

Abstract: The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces. More particularly, the present invention relates to trail compliant side-by-side all terrain vehicles.
