A device that includes an integrated device and a heat dissipating device coupled to the integrated device. The heat dissipating device includes an electro-osmotic (EO) pump. The electro-osmotic (EO) pump includes a casing comprising a first opening and a second opening; a membrane located in the casing; an anode electrode; a cathode electrode; and a catalyst layer formed on a surface of the membrane. The membrane includes a plurality of channels. The electro-osmotic (EO) pump is configured to provide a fluid to flow from the first opening of the casing, through the plurality of channels of the membrane and out of the second opening of the casing. The catalyst layer is configured to recombine gas ions that are produced by the electro-osmotic (EO) pump.

A cooling apparatus is disclosed with a base plate for receiving a heat load from an electric component, an evaporator, a condenser, and a connecting piece for passing fluid from the evaporator to the condenser. In order to efficiently fill the evaporator, the cooling apparatus is provided with a pump for pumping fluid from the condenser to the evaporator.

A valve assembly for an inflation system that includes a pressure relief valve and a vent valve. The pressure relief valve has a pressure relief housing and a pressure relief valve poppet. The pressure relief housing defines a first pressure relief cavity that is disposed between a first end wall defining a first flow port and a first wall defining a passageway and a second pressure relief cavity disposed between the first wall and a second wall. The pressure relief valve poppet is movably disposed within the first pressure relief cavity and the second pressure relief cavity. The vent valve has a vent housing and a vent valve poppet. The vent housing defines a vent cavity that is disposed between the second wall defining a vent flow port and a second end wall. The vent valve poppet is movably disposed within the vent cavity.

A blower/fan with greatly reduced noise levels over conventional blade-based blower/fans (e.g., less than 50 decibels in a leaf blower) with extraordinary longevity due to having virtually no moving parts. The air motivating force comes from an electrohydrodynamic ionic wind created by a very strong electric field crossing two electrodes. This ionic flow strikes air molecules which take away some of the ion momentum, thus amplifying the wind flow. This wind is then further amplified by inducing outside air to be added to this wind by means of a Coand surface at the entrance to the wind tunnel and which then feeds over a slit from which the ionic wind enters into said wind tunnel. A diffuser section follows said slit and causes the wind speed to slow down while at the same time causing the wind pressure to build for optimal exiting air characteristics. The diffuser and Coand surfaces will have minimal drag due to a surface coating that has low air friction (e. g., PTFE Teflon) that is dimpled similar to a golf ball so as to further reduce drag. Such drag reduction lowers wind/surface energy losses and reduces audible noise created by drag. Most of the noise reduction occurs due to the absence of an electric motor as well as having no turbine blades. Unlimited applications for this air movement technology exist, including air transport vehicles, vacuum cleaners, leaf blowers, room fans, drones, etc.

A method of making an additively manufactured ejector pump includes creating a computer file defining the ejector pump in layers. The ejector pump includes a duct extending along a centerline from an upstream end to a downstream end, a nozzle extending inward from the duct including a flowpath, an annulus connected to the duct including a cavity. The method also includes building the ejector pump using an additive manufacturing process that builds the ejector on a layer-by-layer basis from the upstream end to the downstream end.

A rotary energy recovery device (11) wherein a multi-channel cylindrical rotor (15) revolves with its end faces (32) juxtaposed in sealing relationship with end surfaces (33) of a pair of flanking end covers (19, 21), and wherein inlet and outlet fluid passageways (27, 29) are provided in each end cover. Fluid may be directed into the rotor channels (16) and allowed to exit therefrom in an axial direction parallel to the axis of the rotor; however, rotor revolution is self-driven as a result of the interior design of the channels (16) which extend axially through the rotor and are shaped so that fluid flow therethrough creates a torque.
