Patent number: 10288394Abstract: A method of making a fragmenting structure for an explosive device includes placing a volume of fragments of a deformable metal material into a press mold, the fragments having sufficient surface adhesiveness to adhere to each other upon being compressed together, e.g., by coating the fragments with adhesive. The fragments are compressed together in the press mold to form the fragmenting structure as a rigid and substantially void-free structure of compression-deformed, mutually adhering metal fragments, the fragmenting structure being sized and shaped for subsequent incorporation into the explosive device. An explosive device includes an explosive charge and a fragmenting structure adjacent to the explosive charge, the fragmenting structure being a rigid and substantially void-free structure of compression-deformed, mutually adhering metal fragments. The structure may have been manufactured by the disclosed method.Type: GrantFiled: July 8, 2016Date of Patent: May 14, 2019Assignee: Textron Innovations Inc.Inventors: Clayton W. Miller, James A. Hollowell

Patent number: 9747237Abstract: Methods and apparatus for reliable detection and enumeration of devices. In one embodiment, the controller comprises serialized bus protocol (e.g., a Universal Serial Bus (USB)) controller capable of supporting different bus architectures (e.g., USB 2.0 and USB 3.0) of the USB protocol (e.g., eXtensible Host Controller Interface (xHCI) controller). In one variant, when a USB-compliant device is detected over multiple bus architectures of a controller, the controller waits an additional period to allow the device to properly identify which bus architecture to use. After the time period has elapsed, if the device has been determined to be connected over the USB 3.0 bus architecture, the controller waits an additional period of time before enumerating the device. If the device is still present on the USB 3.0 bus architecture, the device continues to enumerate as a USB 3.0 advice to be made available to a host system.Type: GrantFiled: July 13, 2015Date of Patent: August 29, 2017Assignee: Apple Inc.Inventors: Arulchandran Paramasivam, Barry Twycross, Fernando Urbina, James Hollowell

Patent number: 7415931Abstract: Methods and apparatus are disclosed for the controllable deployment of a samara wing from a spinning housing by use of an active deployment system. The active deployment system operates to deploy the samara wing as a function of time, for example a step function, or a monotonic function. The samara wing may be attached to a base, which may include a releasable portion. The active deployment system may include an electronic control unit and release means. Suitable release means include, but are not limited to pin actuators, explosively actuated cutters, and the like. Suitable electronic control units include programmable electronic sequencers and the like.Type: GrantFiled: July 20, 2005Date of Patent: August 26, 2008Assignee: Textron Systems CorporationInventors: Richard P. McConville, James A. Hollowell, Ralph L. Nardone, Norman C. Lariviere, Dean E. Rich, Robert Kingsley

Patent number: 5074716Abstract: An offshore submersible jacket assembly having bouyancy means at the lower portion of the jacket support legs. Relatively short pile sleeves are attached in a cluster to a support leg by shear plates extending generally along the length of the pile sleeves, each sleeve being connected to the leg by a pair of spaced shear plates. Upper and lower transverse plates seal off the ends of the spaced shear plates, creating airtight compartments.Type: GrantFiled: August 27, 1990Date of Patent: December 24, 1991Assignee: Marathon Oil CompanyInventors: James A.

Patent number: 5026226Abstract: A motion absorbing docking assembly for use in subsea docking operations. A tubular docking pile receives a pile head assembly in which a retractable pile head is positioned. When the pile head is impacted by a docking guide on a jacket being lowered into place, axially spaced shock cells having a common central support member absorb the relative motion between the pile head and the docking pile. This arrangement provides for absorption of twice the distance that each individual shock cell is capable of absorbing by itself.Type: GrantFiled: August 27, 1990Date of Patent: June 25, 1991Assignee: Marathon Oil CompanyInventors: James A. Hollowell, Hal C. Wells, Robert W. Robinson

Patent number: 4637313Abstract: A terra-finned earth penetrator having a plurality of axially symmetric fins adapted to rotate in a downward direction in response to off-axis inertial reactive forces generated on impact with earth. The penetrator thereby executes a tuck maneuver within the earth surface thereby avoiding ricochet, broaching or upward turning found in low level weapon delivery systems.Type: GrantFiled: December 31, 1984Date of Patent: January 20, 1987Assignee: Avco CorporationInventors: David Henderson, James A. Hollowell, Howard A. Woodbury
