Abstract: The present invention provides an improved air blowing device formed by a base housing and a motor driving an impeller to create an air flow. A hollow housing is mounted on the base at a connection point. The housing assumes a substantially triangular configuration with the apex of the triangle forming the connection with the base and the forming the top of the housing. The housing is provided with an air discharge slot opening formed by an outer extended flat side wall and an inner shortened flat side wall. The air flow created by the motor impeller enters the hollow housing and exits through the air discharge slot opening thereby creating a collimated beam of air forward of the air blowing device.

Abstract: A motorized portable appliance which monitors, and automatically selects, one of multiple power sources. The motorized portable appliance includes an electric motor, a secondary battery and at least one other source of electrical power, and an automatic control to switch between the secondary battery and the other source of electrical power, which may be mains electrical power, an external secondary battery, an on-board secondary battery, an automotive battery, a solar photovoltaic array, or a primary battery. Power conditioning circuitry converts power from the various power sources to a form compatible with the electric motor and recovers remaining power from depleted primary batteries.

Abstract: The present invention is directed to an improved handheld water misting fan device wherein the power source compartment is positioned within the device at a location remote from the fan motor thereby to remove any structure from the area bounded by the fan shroud. The relocation of the power source compartment leaves the area bounded by the shroud substantially unobstructed thereby to improve air flow. The device is formed in a dog bone shaped configuration to provide a narrow handle section for improved grippability, and an enlarged fluid reservoir at the lower end thereof for greater reservoir capacity.

Abstract: Circuits and methods for protecting polarity-sensitive components, such as light emitting diodes, electrolytic capacitors or integrated circuits, operating from a DC current source including a DC motor, an inductor or relay having a positive terminal and a negative terminal for receiving current from the current source, a protection diode connected parallel with the positive and negative terminals of the motor in a reverse bias configuration, at least one polarity-sensitive component connected in parallel with the protection diode and the DC motor, and a polarity protection transistor connected either between the nominally positive current source terminal and the positive motor terminal, or between the nominally negative current source terminal and the negative motor terminal.

Abstract: A portable hydration system having a fluid reservoir holding body. A sprayer mechanism including a first orifice projecting from a top of the body for (generating and emitting a fluid mist under pressure therefrom. A reclosable drinking nozzle communicating a second orifice with a further location of the top and having a check valve associated therewith to prevent fluid hack flow. The first and second orifices being in fluid communication with said fluid holding reservoir via a fluid conveying tube extending to a common manifold within the body.

Abstract: A portable misting device having a body with an internal and fluid holding reservoir. A fill port provides for refilling of the fluid holding reservoir and one or more discharge ports are in fluidic communication with the reservoir. A fluid conveying conduit extends from the discharge port and terminates in an orifice. The orifice typically includes both spray misting and drinking components.

Abstract: A portable misting fan having a compact and three-dimensional body. An impeller includes a plurality of rotatable fan blades mounted to the body. An elongated and linearly actuating pump is incorporated into the body. A first end of the pump cylinder defines an inlet in communication with a fluid reservoir. A second end of the pump cylinder defines an exposed orifice in communication with a path of rotation associated with the fan blades, the orifice mounting to a discharge portion axially displaceable relative to an intermediate cylinder portion of the pump. A trigger is pivotally secured to the body, a portion of the trigger including a cam surface arranged in opposing and coacting fashion relative to a cam surface associated with the orifice. Upon depressing the trigger, the discharge tube is caused to displace inwardly relative to the cylinder portion, a spray mist issuing from the orifice and into a path associated with the rotating fan blades.
