The invention relates a method and apparatus for reducing the drag on aircraft, particularly aircraft with an upswept afterbody. The method includes the steps of positioning a plurality of drag reducing elements on the fuselage of the aircraft, wherein the drag reducing elements are positioned on the fuselage from a position at the breakline of the fuselage and extending toward the tail of the aircraft. In preferred embodiments, each of the plurality of drag reducing elements is positioned such that a first end of the drag reducing element is at an angle of between approximately 15 and 35° nose up relative to the flow of air about the fuselage at the location where the drag reducing element is positioned.

A method for forming a low temperature cofired ceramic (LTCC) device includes forming a channel in a first LTCC tape layer. A wax is inserted in the channel. The wax is of a type that burns out at a temperature below a sintering temperature of the first LTCC tape layer. At least a second LTCC tape layer is stacked on the first LTCC tape layer to form a stack. The stack is pressed sufficiently for the first and second layers to bond into a laminate. The laminate is fired at the sintering temperature to form a sintered ceramic structure from the first and second LTCC tape layers, so that all or substantially all of the wax is burned out from the channel.

The present invention is a new and distinct thorny blackberry cultivar named ‘Chesapeake’, which is capable of producing very large fruit in the spring midseason, the fruit being much larger and similarly durable than that of the standard cultivars. The cultivar is characterized by moderate suckering ability, recurved thorns and its very flavorful fruit which is edible even when the fruit is immature.

The present invention is a new and distinct fall bearing red raspberry cultivar named ‘Josephine’, which is capable of producing fruit on primocanes, the fruit being larger, with tougher skin and more cohesive than that of the standard cultivars. The cultivar is characterized by moderate suckering ability and its large, round and extremely symmetrical fruit which ripens later than standard cultivars. Most drupelets tear apart rather than separate from each other and it is common to observe perfectly curvilinear rows of drupelets, i.e. along the latitudinal circumference of the fruit.

The present invention reveals a method and apparatus for more efficiently injecting a primary fluid flow in a fluid ejector used to pump lower velocity fluid from a secondary source. In one embodiment, the primary fluid flow is a pulsed or unsteady fluid flow contained within an inner nozzle situated within a secondary flow field. This secondary fluid flow is bounded within the walls of an ejector or shroud. The secondary and primary fluid flows meet within the ejector shroud section wherein the secondary fluid flow is entrained by the primary fluid flow. The geometry of the ejector shroud section where the primary and secondary fluids mix is such as to allow the beginning of primary injector pulse to be synchronized with an acoustic wave moving upstream through the ejector initiated by the exiting of the previous pulse from the ejector shroud. The ejector's geometric properties are determined by the acoustic properties, frequency, duty cycle, and amplitude, of the pulsed primary fluid flow. Furthermore, the frequency, duty cycle and amplitude of the primary fluid flow may be varied in order to vary the efficiency of the injector.

A method and system for detecting and correcting error conditions on sequential devices in a private loop direct access fiber channel network respectively include the steps and instructions for determining the state of an exchange using an initiator and initiating an appropriate sequence level recovery using the initiator. The invention further includes determining whether a target response is overdue using a timer in conjunction with internal driver state information for indicating that packet information may have been lost. The invention further requests exchange and sequence state information from the target for determining the need for corrective action and takes the needed corrective action, such as resending sequence information, requesting that the target resend sequence information, or providing early indication to the ULP that an error has occurred.

Ths invention relates to a new and distinct fall bearing golden fruited raspberry cultivar named `Anne` which is capable of producing fruit on primocanes, the fruit being larger and more cohesive than that of the standard cultivars. The cultivar is characterized by moderate suckering ability, and its round-conic, light colored and symmetrical fruit. Additionally, it is characterized by its sparsely thorny upright canes, with fall fruit appearing on the upper quarter of the cane.

A method for managing data packets passing through an Ethernet node having multiple ingress ports and multiple egress ports, the ingress ports receiving the data packets from at least one service, and the egress ports configured with at least one Logical Transport Resource (LTR) configured as a predefined path between one of the egress ports and a destination in the Ethernet network. The method comprises mapping one or more of the services to each of the at least one LTR, shaping each of the at least one LTR to a configured rate, and transmitting data packets to the Ethernet network via the egress ports.
