Abstract: An apparatus for heating fluid for use on a vehicle surface includes an extrusion extending axially, a first port extending axially through the extrusion adapted to receive a heating element and a second port spaced axially from the first port and extending axially through the extrusion adapted to receive a thermal sensor and a thermal fuse, and at least one fin extending axially along the extrusion and radially oriented about the first port and the second port, whereby the heating element conveys heat to the extrusion which then transfers thermal energy to fluid flowing past the at least one fin.

Abstract: A bus includes a vehicle body, a plurality of doors, a weather seal, at least one sensor disposed inside the weather seal, wherein the at least one sensor capacitively couples to an electrically conductive moving object proximal to the weather seal such that the capacitance of the at least one sensor changes, and a controller coupled to the at least one sensor, the controller analyzing the sensing by the at least one sensor and being configured to alert an operator of the bus when the obstruction is present.

Abstract: A cooling system connected to provide coolant to a welding-type component automatically circulates coolant through the welding component upon activation of the welding component. A controller is configured to regulate the cooling system such that upon activation of the welding-type component coolant is caused to at least flow through the welding-type component, and circulate after deactivation of the welding torch until a temperature of the coolant falls below a certain value or a specified time period has expired. The cooling system is constructed to be integrally disposed within a power source housing.

Abstract: A spark gap point and spark gap assembly for a welding-type device are disclosed for igniting and stabilizing a welding-type arc. A double-headed spark gap point having spark gap surfaces on two ends is incorporated into a spark gap assembly with a pair of single-headed spark gap points that each have only a single spark gap surface. All spark gap points are arranged coaxially on a base so that each spark gap surface faces another spark gap surface. A spark gap is created between each set of opposing spark gap surfaces. When a high voltage is applied across the spark gap points, sparks periodically arc across the spark gaps, creating a high frequency, high voltage signal usable to ignite or stabilize a welding-type arc.
