International Classification:

B32B 3/26
B29C 70/30
B32B 3/12
B29C 44/02

US Classification:

428116, 264 455, 156245, 4283044

Abstract:

A composite structure includes a first face sheet, a second face sheet, and a foam member located between the first face sheet and the second face sheet. The foam member has a molded contour, the mold contour being configured to provide tooling surface for at least one of the first face sheet and the second face sheet prior to curing of the composite structure. A method of making the foam member includes creating a mold tool having an interior surface which resembles the desired outer contour of the foam member. A mixture is poured into a pour opening in the mold tool. The mixture is allowed to polymerize into a foam as the foam expands and distributes within the mold tool. Vent openings in the mold tool are selectively tailored to control the density of the foam member. The foam member is cured in the mold tool.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1210

US Classification:

364200

Abstract:

An improvement in a bus converter that provides a bus to bus address translation function permitting access from an I/O device connected on the I/O bus to a system bus and system memory, where the bus converter includes a circuit connected to the I/O bus to partition I/O addresses received from the I/O bus into a lower order field and a high order field and connected to a circuit to receive DMA ID's from the I/O bus to combine this DMA ID with the high order field to form a first combined address. The first combined address is input to a memory which provides corresponding control field and prefix field data. An address formatter is further included that is connected to receive the control field and prefix field data from the memory and further connected to receive the low order address field. The address formatter forms a second combined address from the prefix field, control field and lower order address field. This second combined address is then provided to a system bus to permit access to the system bus.

B64C 39/02
B64C 27/06

Abstract:

A system for deploying and retrieving a parasite aircraft includes a parasite aircraft with a dock and a carrier aircraft that includes a maneuverable capture device tethered to the carrier aircraft via a cable. The maneuverable capture device includes a plurality of rotors and is configured to dock in the dock of the parasite aircraft. A method of deploying a parasite aircraft includes positioning a parasite aircraft on a loading surface; positioning a carrier aircraft above the parasite aircraft; releasing, from the carrier aircraft, a maneuverable capture device comprising a plurality of rotors; securing the maneuverable capture device to a dock positioned on the parasite aircraft; lifting, via a cable secured at a first end to the carrier aircraft and at a second end to the maneuverable capture device, the parasite aircraft with the carrier aircraft; and releasing the parasite aircraft from the maneuverable capture device.
