Abstract: The present pull-type snow blower attachment comprises a housing, a auger and a snow blowing fan arrangement. The housing defines a longitudinally curved surface between two walls. A hitch protrudes away from the surface and is adapted for attachment behind a vehicle. The auger is rotatably secured to the walls of the housing. The auger defines two opposite sections and a middle section therebetween. Each opposite section is equipped with a spiral blade angled towards the middle section, and the middle section is equipped with at least two blades for lifting snow. The snow blowing fan arrangement includes a fan and a chute section above the fan. The fan is between the auger and the hitch. The fan is adapted for receiving snow lifted by the at least two blades of the auger and pushing the snow through the chute section.

Abstract: A hitch for connecting an implement to a vehicle. The hitch comprises a first frame for attachment to the vehicle and a second frame for attachment to the implement. The hitch further comprises a mechanism for connecting the first frame to the second frame. The connection of the first frame to the second frame provides for connecting the implement to the vehicle when the first frame is attached to the vehicle and the second frame is attached to the implement.

Abstract: A Power Take-Off (PTO) coupler and equipment equipped therewith. The PTO coupler comprises a first extremity to be connected to the equipment and a second extremity. The second extremity has a plurality of teeth along a circumference thereof, wherein subsequent teeth are separated from one another by a gap, and each of the teeth has a base narrower than its top. When the PTO coupler is engaged to a corresponding receiving coupler, the interlocking of the plurality of teeth and gaps counteract axial load generated during operation of the PTO coupler.

Abstract: Disclosed is a threshold selector that selects a threshold by generating a histogram from a detector signal and a flow cytometer. The detector signal includes both data and noise. A histogram is generated, which includes height data from the pulses of the detector signal as well as noise. The flow cytometer can be operated without samples to generate a histogram that includes only noise. The threshold signal can then be selected by selecting an intensity level on the histogram that is between the noise and data.

Abstract: A hitch for connecting an implement to a vehicle. The hitch comprises a first frame for attachment to the vehicle and a second frame for attachment to the implement. The hitch further comprises connection means between the first frame and the second frame for connecting the implement to the vehicle when the first frame is attached to the vehicle and the second frame is attached to the implement.

Abstract: A snow blower comprises a frame, an auger, a fan, a hydraulic system, a rotating drum, a securing mechanism and a disengagement mechanism. The auger is rotationally mounted to the frame, and is adapted for collecting snow. The fan is mounted upon the frame, behind the auger, and evacuates the collected snow in the rotating drum. The hydraulic system rotates the rotating drum with respect to the frame. The rotating drum defines a pair of teeth about a circumference thereof. The securing mechanism is affixed to the frame, and includes on one extremity a pair of complementary circular cams, and on a second extremity a pressure mechanism for applying pressure on the pair of complementary circular cams to keep the pair of complementary circular cams engaged.

Abstract: A coupler assembly for coupling an accessory to a vehicle chassis. The coupler assembly includes a male portion having a male attachment end and a conical male portion, the male side walls each having a male pin aperture, a female portion having a female attachment end and a conical female portion, the conical female portion adapted to at least partly receive the conical male portion, the female side walls each having a female pin aperture, the female pin apertures adapted to be aligned with the male pin apertures when the conical male portion is at least partly received in the conical female portion and two pins adapted to be displaced from a retracted configuration wherein the pins are one of fully contained within the conical male portion and outside the conical female portion and an extended configuration wherein the tip ends of the pins extend through both the male pin apertures and the female pin apertures when the conical male portion is at least partly received in the conical female portion.
