Abstract: A wind turbine blade assembly for a wind turbine having a root portion proximal to a hub of said wind turbine and a tip portion distal to said hub, comprising a primary airfoil having a primary leading edge and a secondary airfoil having a secondary leading edge wherein there is an aerodynamic gap between said primary airfoil and said secondary airfoil, with said primary airfoil configured to be located upwind of said secondary airfoil when assembled on the wind turbine.

Abstract: A real-time path-directed controller is disclosed. The controller is extraordinarily well-suited for navigating a vehicle along a desired path across a field for agricultural applications. The controller comprises several important assemblies. It comprises a position sensor which produces an object position signal to an object position signal conditioning module (which, in turn, produces a conditioned object position signal to a controller summer). The controller also comprises a heading conditioning module for receiving the object position signal and conditioning the object position signal to produce a conditioned heading signal to the controller summer. The controller also comprises a control apparatus sensor for producing a control apparatus signal to a control apparatus signal conditioning module (which, in turn, produces a conditioned control apparatus signal to the controller summer).

Abstract: A real-time path-directed controller for navigating an object along a desired path is disclosed. The controller comprises: a position sensor which contributes to the production of a conditioned object position signal to a controller summer; a heading conditioning module which contributes to the production of a conditioned heading signal to the controller summer; a control apparatus sensor which contributes to the production of a conditioned control apparatus signal to the controller summer; and a control apparatus null position conditioning module which contributes to the production of a conditioned null position signal to the controller summer. The controller summer sums the signals to produce a controller summer signal to a controller summer conditioning module so as to produce a control apparatus control signal to a control apparatus controller so as to direct the control apparatus and thereby direct the object by feedback control along the desired path.

Abstract: A coaxial propulsion system has a primary propeller, a flow control element to reduce swirl, and a secondary propeller, mounted in series configuration. A connecting shroud directs the combined thrust. Said primary propeller and said secondary propeller may be connected to the same engine, or independent engines for greater reliability and performance. A coaxial jet fan system has a primary fan, a flow control element to reduce swirl, and a secondary fan, mounted in a series configuration. A connecting shroud directs the combined bypass and jet thrust. Further, a secondary shroud provides a primary bypass and a secondary bypass thrust, thereby establishing a greater level of control over the bypass ratio and engine efficiency.

Abstract: A series fan assembly has a primary fan, a flow modification element to reduce swirl, and a secondary fan, mounted in a series configuration. A connecting sleeve directs the combined output into an enclosure containing components to be cooled, or a heat sink. A sliding drawer is configured within said connecting sleeve to detachably hold said primary fan, said flow modification element, and said secondary cooling fan, allowing for the hot swappable replacement of defective components. A controller is in communication with a power source, said primary fan, said secondary fan, and at least one sensor monitoring the status of each of said primary fan and said secondary fan. Said controller is configured to maintain said combined output above a minimum control level at all times, in the event of the failure of said primary fan or said secondary fan.

Abstract: An article carrying device is provided for balancing upon a single shoulder of a person. The device includes front and back extended end members having a plurality of clips provided along middle and distal portions of the ends members. The clips secure packages to the article carrying device such that when packages of equal weights are attached to both ends of the carrying device, the device balances upon the shoulder of the person and does not require human hand intervention to maintain its position. The article carrying device is interchangeable and can be employed on either shoulder of the person. A hinge mechanism can be provided at an apex of the device for permitting the collapse of said device for transport or storage when not is use.

Abstract: A system for vacuum packaging foods and other perishable items, including a front loading appliance and a hand held appliance. A multiple stage vacuum and sealing process enhances performance. Low cost vacuum bags are formed using a continuous process. A visible indicator assures consumers that a safe level of vacuum has been reached and maintained.

Abstract: The invention comprises an eyeglass holder. In one embodiment, the eyeglass holder comprises a toy or doll figure to encourage children to wear and take care of eyeglasses.

Abstract: A food wrapper with rip line capable of being sealed for food prior to consumption and being a holder for food during consumption, the rip line being perforated or partly perforated. Also taught is a condiment or premium pocket. Also taught is a food bag with rip line having an external complementary product pocket for holding french fries and the like.

Abstract: A rapid cool iron has a body and a low specific heat sole plate having an element bonded to or formed upon a top surface, said body and said sole plate being separated by an air gap to allow for the free flow of air over said top surface of said sole plate. Also taught is a fan to more rapidly cool the sole plate through forced convection. Also taught is a controller that is configured to only apply power when the rapid cool iron is in a horizontal orientation. Also taught is a steam generator which may be independent from or integrated with the sole plate, an external water reservoir/stand which includes a water filter, an ergonomically designed tilt handle with integrated controls and a grip sensor, and a forward facing light to illuminate the material being ironed.
