摘要： A flue exhaust fan has a configurable upwardly facing outlet for delivery of a mixture of gas and ambient air from the water heater or a furnace into either a vertical flue or a horizontal flue. Because the horizontal flue necessarily includes a 90° transition between the upwardly facing outlet and the horizontal flue, the horizontal flue has a greater flow resistance than the vertical flue. By installing a straight connector with a flow resistance element, the gas flow resistance encountered by the flue exhaust fan is the same for a vertical flue and a horizontal flue therefore requiring a single flue exhaust fan with a flow rating for installation with a horizontal flue or a vertical flue.

摘要： An EC motor with an encapsulated electronic controller. The electronic controller is encapsulated by creating a silicone mold to include sufficiently detailed voids so that certain parts of the electronic controller adjacent the voids are encapsulated and other parts adjacent where the mold has no voids are left unencapsulated.

摘要： An EC motor with a rotor. The rotor has a hub with outwardly extending silicon steel laminates with gaps between. Rectangular neodymium permanent magnets are positioned in the gaps. Wedge-shaped ferrite permanent magnets are positioned radially between the silicon steel laminates and the hub of the rotor.

摘要： An EC motor with a stator and a rotor mounted to a shaft. The motor has a cooling system, an over molded stator housing, and an optimized rotor. The stator has teeth with wound electromagnetic coils. The teeth and coils are distributed circumferentially with gaps between adjacent coils. The stator is over molded with plastic that forms axially oriented cooling passages between adjacent coil sections. An impeller fan then draws air into the motor through air inlets connected to air passages. The impeller fan directs the air through the axially oriented cooling passages in the stator and out air outlets. An optimized internal rotor has permanent magnets and silicon steel laminates spaced circumferentially and extending outwardly from a central hub. Rectangular shaped magnets are interposed in the gaps between the laminates. Wedge-shaped magnets are aligned radially with the laminates and between the laminates and the hub.

摘要： A method is provided for limiting double-frequency internal power distortion in a power system. The method includes receiving an input voltage from a voltage source at a power converter from which an output power is provided to an electrical load, measuring the output power having a waveform with a steady-state component and a double-frequency transient component, executing computer-readable program code, via processing circuitry, to determine a compensating waveform equal in amplitude to the double-frequency transient component, and that is anti-phase to the double-frequency transient component, and causing the power converter to generate the compensating waveform such that the waveform and the compensating waveform superpose, and the double-frequency transient component of the waveform and the compensating waveform destructively interfere, leaving the steady-state component that is delivered to the electrical load.

摘要： A hinge assembly for pivotally joining the opposing halves of a carryable case, especially a case for housing an electronic apparatus. The disclosed hinge is adapted to convey electrical conductors from one half of the case to the other, while protecting them from damage by excessive flexing, abrasion, moisture, and debris.
