Abstract: Radar systems and methods detecting and tracking an unmanned aerial system (UAS) are provided. The radar system and methods can include determining whether or not a UAS is included in the plurality of electromagnetic signals received by the radar system based on one or more expected frequencies that one or more UAS devices use to transmit signals to remote controls. The radar systems and method can also involve switching the radar system into a track mode upon detecting a UAS.

Abstract: A method of determining a distance to be walked by a delivery vehicle driver including providing a satellite image that has an image of a building to which an item is to be delivered and an image of a street adjacent to the building. The method further includes defining a path, within the image, that corresponds to a path that the delivery vehicle driver will walk when delivering the item to the building. The method also includes the step of determining a length of the path.

Abstract: A method of brazing the nodes of honeycomb core material and the top and bottom panels to the honeycomb core material to form a sandwich structure. The method comprises the insertion in selected cells of the core, a coil or loop formed of normally flat resilient braze foil ribbon under tension and then releasing the tension to allow the braze foil, coil or loop to be urged against the cell walls under its own resiliency. The top and bottom panels are then installed over the core adjacent to the cell faying edges to form top and bottom surfaces. Pressure is then applied from the panels toward the honeycomb core material. The temperature of the sandwich structure is then elevated until the braze foil is caused to melt. Capillary attraction causes the now liquid braze material to flow into the interstices between the cell nodes and between the faying edges of the honeycomb core cells and the adjacent panels.

Abstract: A vacuum tool for a vacuum bagging curing operation comprising a base on which is placed a one piece vacuum bag comprising a top sheet with a peripheral sealing means attached thereto which cooperate to seal the bag in a zipper-like fashion, thus enclosing workpiece therein for the vacuum curing operation. A vacuum manifold is attached to the base to connect the tool to a vacuum pump to create a vacuum between the base and bag.

Abstract: An air inlet duct for a jet propulsion missile or other vehicle which is movable between a housed, pre-launch position and an extended or deployed flight position. A method of manufacturing the duct is also disclosed. The duct system includes a flexible leading edge attached to a double-wall inflatable duct body. Drop threads extend between the duct body walls to hold an exact desired contour when the duct is inflated. A pivotable plate moves the inflatable duct between a housed, deflated, position and an inflated flight position. Manufacture of the inflatable duct is basically accomplished by preparing a foamed plastic form in the desired duct wall shape, covering the form with fabric, stitching through the foam and fabric, coating the fabric with a flexible sealing compound, dissolving away the foamed plastic and attaching the resulting inflatable duct to other missile components.

Abstract: A device for limiting the travel of an arbor press when pressing inserts into a panel. Two insert halves are pressed into a panel from opposite sides by means of an upper and lower anvil. The press movement is stopped by the device when a specified gap between the insert head and the exterior surface of the panel is obtained, compensating for any variations in the panel thickness.

Abstract: A device to code a machine tool holder, to preset the tool length, to mount the tool in the holder, and to inspect tool dimensions and coding. These functions are performed by a ring selector which selects different outside diameter rings in such sequence that a desired indentification of a tool by a combination of lands and grooves is accomplished, by a power torque machine which tightens the tool holder collet, by a digital height and diameter gage device which inspects the tool dimensions, and by a digital ring counter which gives a digital readout of the land and groove combination on the external surface of a tool holder.

Abstract: A mounting assembly for supporting an ultrasonic transducer within a machine tool. An ultrasonic tube assembly mounted coaxially within a machine spindle and tool supports an ultrasonic sensor adjacent to the surface being machined during machining. The tube mount includes means for isolating the tube assembly from vibration of the spindle and tool. Real-time thickness measurement of the surface being machined can be obtained by using thickness as measured by the ultrasonic sensor in a conventional feedback loop, controlling tool position.

Abstract: A refrigerating apparatus enclosing the rivet hoppers of an automatic riveting machine. A refrigerant such as liquid nitrogen is conducted into the refrigerant coils of an insulated enclosure to maintain the temperature of the rivets in the hoppers at sub-zero temperature in order to retard the age hardening process. Frost formation on the rivets is effectively prevented by purging the enclosure with gaseous nitrogen. Upon passing through the coolant coils, the nitrogen absorbs sufficient heat to convert it from the liquid state to a gaseous state. The gas then discharges from the open end of the coils into the enclosure and through a vent in the side wall of the enclosure to atmosphere. To augment frost prevention, dry nitrogen gas is utilized to propel the rivets from the hoppers into the fingers of the riveting machine. Down time for servicing, changing rivets, etc. is reduced to a minimum by a temperature controlled space heater mounted inside the enclosure.

Abstract: An accessory for riveting machines, replacing the conventional lower anvil, which permits both the top and bottom exposed surfaces of a laminated assembly to be countersunk and flush riveted. It includes a selectively and sequentially engageable sheet clamping means, countersinking means, rivet anvil, and rivet squeezing means.
