Patent number: 6451152Abstract: Composite articles are produced by guiding composite tape material through a compaction region where the tape material is pressed onto a substrate, and heating the tape and substrate ahead of the compaction region by irradiating opposing surfaces of the tape and substrate with laser radiation produced by a laser diode array. The laser diode array is divided into independently controllable diode groups, and the diode groups are controlled so as to independently control heating of one area of the tape and substrate relative to another area of the tape and substrate. In one embodiment, the widthwise profile of the light energy is such that a widthwise portion of the tape at an inner radius of a curved path along which the tape is steered at the compaction region is heated to a greater extent than a widthwise portion of the tape at an outer radius of the path.Type: GrantFiled: May 24, 2000Date of Patent: September 17, 2002Assignee: The Boeing CompanyInventors: Scott Holmes, Stanley A.

Patent number: 5952836Abstract: A device for detecting fractures or corrosion in a workpiece having a non-conductive outer surface. A thin film layer of metallic material comprising a plurality of separate crack detection wires is bonded to the non-conductive surface of the workpiece. A top coating of protective material is applied to the thin film layer to protect the detection wires from abrasion and corrosion. When an electrical current is transmitted through the detection wires, a predictable resistivity pattern is viewable on a monitor. As a fracture propagates through the workpiece causing the crack detection wires to break one-by-one, the change in resistivity of the wires can be monitored and the existence and extent of any fracture or corrosion to the wires determined.Type: GrantFiled: April 28, 1997Date of Patent: September 14, 1999Assignee: McDonnell Douglas CorporationInventor: John M.

Patent number: 5796025Abstract: A fiberoptically illuminated electronic stringed musical instrument is disclosed that has at least one pickup. At least one light source is disposed within the body of the instrument. A plurality of optical fibers are embedded in the instrument such that each fiber extends from the light source to a predetermined location on the exterior surface of the instrument. The fibers provide a transmission path for the light rays emitted by the light source, thereby illuminating the exterior surface of the instrument while at the same time the fiber becomes part of the mechanical/composite structure of the guitar. Control circuitry, disposed within the body of the instrument, is connected to the pickup and the light source. The control circuitry selectively controls the illumination of the light source, and therefore the exterior surface of the instrument, based upon electrical signals generated by the pickup.Type: GrantFiled: December 13, 1995Date of Patent: August 18, 1998Inventor: John M.
