Unmanned Aerial Delivery System
ActiveUS20160257423A1Minimize charge timeIncrease rangeUnmanned aerial vehiclesRemote controlled aircraftInitiation pointMultiple delivery
An unmanned aerial vehicle delivery system utilizes an unmanned aerial vehicle (UAV) to deliver packages between an initiation point and multiple delivery points at a raised elevation. The UAV flies between points in an organized manner, using logistical, maintenance and safety software, commands from a delivery organization, and guidance tools to coordinate deliveries. One advantage of the system is that the UAV engages the delivery points at a raised elevation, rather than the ground level. The UAV docks through an elevated structure at the delivery point for delivering the package and replenishing a power source. The package is conveyed from a docking end and through a central shaft of the elevated structure by means of an elevator. The package then travels to a lower structure, such as a house or office, for pickup. After completion of the delivery, the UAV replenishes its power source and / or continues on the delivery route.

Coaxial plasma arc vapor deposition apparatus and method
An apparatus for the deposition of a variable thickness coating onto the inside of a cylindrical tube comprises a variable pressure gas, an cathode coaxially positioned within the cylinder, and a voltage source applied between the cathode and cylindrical tube, which functions as an anode. A radial plasma arc is generated between the anode and cathode at a starting point on the cylinder, and the plasma arc travels down the central axis of the cylinder, providing a helical deposition region on the inside of the cylinder. Selection of the combination of cathode material and gas enable the plasma to generate ionic material which is deposited on the anodic cylinder in the region of the plasma. By varying the pressure of variable pressure gas for each helical path, it is possible to vary the composition of this deposition film.

Multi-perf fracturing process
InactiveUS20060243443A1Wide spaceGreat propensityFluid removalDrinking water installationInitiation pointShortest distance
A method is shown for fracturing a subterranean formation from a deviated well bore. A plurality of spaced fracture initiation points are created in the well bore. Hydraulic pressure is applied to all of the sets of perforations at the fracture initiation points to extend a plurality of spaced fractures in the formation in directions substantially perpendicular to the deviated well bore direction. The same perforated interval in the wellbore is shot two or more times, using a conventional perforating gun in order to achieve a desired hole count over a shorter distance. The perforating technique is combined with a pumping protocol which better insures that the fracturing fluid being pumped flows more evenly through each set of perforations upon the application of hydraulic pressure rather than the majority of the fluid entering only the first perforated interval of the wellbore.

Defrost mode for HVAC heat pump systems
InactiveUS20050172648A1Smooth transitionProlong lifeHeat pumpsEvaporators/condensersInitiation pointEngineering
A heat pump, and in particular a heat pump for heating a hot water supply is provided with an improved defrost mode. The defrost mode is actuated to remove frost from an outdoor evaporator that may accumulate during cold weather operation. An algorithm for operation of the defrost mode is developed experimentally by seeking to maximize the heat transfer provided by the refrigerant. A heating system condition is experimentally related to the heat transfer capacity. One then maximizes the average heat transfer capacity to determine the optimum initiation point for the defrost mode. Further, protections are included into the defrost mode. When the heat pump is utilized to heat hot water, methods are provided to prevent the water that remains in the heat exchanger from becoming unduly heated. In one method, the water pump may be periodically operated to move the water. In a second method, a control ensures the discharge pressure of the refrigerant leaving the compressor is reduced, and that the water pump is not stopped until that reduced temperature falls below a predetermined maximum. The temperature reduction is achieved through a dual control loop wherein a temperature that is too high results in a new desired discharge pressure. The control achieves the new desired pressure by controlling the expansion device. In another protection feature, as a control determines that the defrost mode is nearing its end, an evaporator fan is run to remove melted water from the evaporator coils, and also to ensure the refrigerant leaving the evaporator does not reach unduly high pressure or temperatures.
