Publication number: 20150053126Abstract: The problem of penetrating through nets and other objects is solved by cutting the object using a linear cutting assembly having a linear cutter arm that moves in an arc and pivots about an attachment point. The object is cut by a severing action caused by a moveable blade of the linear cutting arm moving back and forth across a stationary blade of the linear cutter arm. An underwater vehicle modified to incorporate an embodiment of the linear cutting assembly can cut a sufficiently large opening in the object to allow the vehicle to pass through.Type: ApplicationFiled: October 30, 2014Publication date: February 26, 2015Inventors: James Wiggins, Chris Norkoski, Conrad Zeglin, Walter Allensworth

Patent number: 8961079Abstract: The problem of penetrating through nets and other objects is solved by cutting the object using concentric cutters in which a rotatable cutter having floating teeth rotates concentrically about a stationary cutter having fixed teeth. The object is cut by a severing action caused by the floating teeth of the rotatable cutter sliding against the fixed teeth of the stationary cutter. Embodiments of the invention include a UUV system for penetrating through fishing nets and other objects, concentric cutting assemblies for use in the UUV system and other systems, and a method for penetrating through fishing nets and other objects. A UUV system in accordance with an embodiment of the invention has a concentric cutting assembly at the forward end and a propulsor at the aft end. The concentric cutting assembly integrates seamlessly within the UUV housing and is deployed from the forward end of the UUV, enabling the UUV to quickly and efficiently penetrate through objects blocking its path.Type: GrantFiled: January 16, 2014Date of Patent: February 24, 2015Assignee: Adaptive Methods, Inc.Inventors: Jim Wiggins, Walter Allensworth, Conrad Zeglin

Patent number: 7576281Abstract: The present invention relates to an apparatus for altering the course of a moving article and a method thereof comprising of a launching aircraft or surface craft to deploy said apparatus towards a moving article. The apparatus comprises of a driving mechanism (10), wherein said driving mechanism (10) further comprises of a plurality of sections such as a nose section (12), a propulsion section (14), a drag chute section (16) and a cutting section (18), and wherein said sections are integrally connected with one another in a tight and secure manner. The driving mechanism (10) is capable to be launched from an aircraft or a surface craft towards a target and wherein upon launch said driving mechanism (10) is capable of steering itself on its own towards its target and thereafter attaching itself to the target and wherein by using the drag chute section (16).Type: GrantFiled: June 15, 2007Date of Patent: August 18, 2009Assignee: Singapore Technologies Dynamics Pte LtdInventors: Pao Chuen Lui, Saik Hay Fong, Hong Soon Tan, Tee Peng Toh
