Abstract: A portable fan having a power supply, a motor coupled to a plurality of fan blades and powered by the power supply, and a battery pack coupled to the portable fan and configured to provide power to the power supply. The portable fan further includes a controller configured to receive power from the power supply. The controller is configured to receive an input to control the motor at a requested speed, operate the motor at the requested speed, and initiate a ramp-down operation, wherein the ramp-down operation is configured to ramp down the speed of the motor from the requested speed over a period of time.

Abstract: A vacuum cleaner system comprising a motor-impeller assembly, a power source, and a hose. The motor-impeller assembly is configured to generate fluid flow, the fluid flow passing through a hose inlet. The power source is configured to supply power to the motor-impeller assembly. The hose includes a proximal hose end configured to be coupled to the hose inlet, a distal hose end spaced from the proximal hose end, and a hose body. The hose body is coupled to the proximal hose end and the distal hose end. The hose body has an inner surface through which fluid flow passes, and an outer surface open to the surroundings of the hose. The hose further includes a layer of anti-static material applied to either the inner surface of the hose body or the outer surface of the hose body.

Abstract: A portable heater includes a housing defining a base portion and a radiant heating assembly positioned within the housing. The radiant heating assembly includes a connector configured to receive a fuel tank having a combustible fuel, an ignition assembly configured to ignite the combustible fuel, and a radiant heating surface configured to be heated by ignition of the combustible fuel. The radiant heating surface is configured to emit radiant energy to a surrounding environment. An air flow channel is formed in the housing defines an intake opening and an exhaust opening. The exhaust opening is positioned proximate the radiant heating surface. A fan is positioned within the air flow channel to induce an airflow through the air flow channel. The airflow exits the exhaust opening to disperse the radiant energy from the radiant heating surface to the surrounding environment.
