Publication number: 20230038648Abstract: Diver propulsion devices and methods of propelling the devices and divers upon and beneath the sea are presented. A diver propulsion device is comprised of a wing buoyant in water, an electric motor propulsion system, a leash interconnecting the wing and diver, which leash may integrate control circuitry of the motor, photovoltaics atop the wing, and, batteries, each electrically connecting the motors, fins attaching the wing provide hydrofoil flight stabilization, and foot constraints attaching a deck of the wing. The wing is a hydrofoil, and the diver stands and lies upon the deck of the wing, and, during hydrofoil flight, the diver is substantially above the sea and the wing is seaborne. In hydrofoil flight, the device may be motor propelled, or, by the diver heaving and pitching the device, or, by both methods simultaneously. Undersea, the device tows the diver by motor power energized photovoltaically, and, or, by battery.Type: ApplicationFiled: September 20, 2022Publication date: February 9, 2023Inventor: Drew Allen Krah

Patent number: 11511831Abstract: A wing, buoyant in water has an upper wing surface comprising a deck upon which a rider stands, and, the wing is in water. A foot constraint proximate the wing leading edge and fixedly attaching the wing projects outwardly from the deck to release-ably receive the rider's forward foot. With the rider standing with both feet upon the deck, and the rider's forward foot ensconced within the foot constraint, and with the rider's aft foot proximate a trailing edge of the wing, the rider bodily heaves and pitches the wing to obtain a chordwise forward velocity thru the water. The forward foot constraint enables the rider to upheave the wing. A second foot constraint may attach the deck proximate the wing trailing edge. Another foot constraining system is comprised as a frictional device broadly applying the deck, and, may be used in addition to or in lieu of other constraints.Type: GrantFiled: October 12, 2019Date of Patent: November 29, 2022Inventors: Drew Allen Krah, Maya Jane Krah, Glen Edward Krah

Patent number: 11430471Abstract: A disk drive is operable to determine degradation associated with writing to a disk surface by a head which has written existing data at a first areal density. A second areal density less than the first areal density is determined that remediates the degradation. The disk drive performs subsequent writes to the disk surface at the second areal density, and continues to read the existing data at the first areal density.Type: GrantFiled: December 18, 2020Date of Patent: August 30, 2022Assignee: Seagate TechnologyInventors: Drew Allen Cheney, Edward Charles Gage, Praveen Viraraghavan

Patent number: 8974456Abstract: A dynamic tissue holding device for dynamically holding two tissue portions in contact with one another includes a resilient body having a spring and a band arranged for extending about the tissue portions to be held together. The band has a first end for attachment to a first attachment portion on the resilient body and a second end for attachment to a second attachment portion on the resilient body. Stops are disposed on portions of the resilient body for limiting both the compression and expansion of the spring. The compression of the spring is limited by engagement of two of the stops with one another and the expansion of the spring is limited by engagement of at least one of the stops with the spring.Type: GrantFiled: May 21, 2012Date of Patent: March 10, 2015Assignee: Dallen Medical, Inc.Inventors: Drew Allen, Seth Arnold Foerster

Publication number: 20120024937Abstract: A method and apparatus for interosseous bone fixation uses a compression staple, generally U-shaped, having a pair of legs with sharp front ends and proximal ends interconnect by a bridge portion that is resilient and bowed, the staple having an initial configuration and capable of a tensioned configuration by spreading apart the legs by a certain amount causing the curvature of the bowed bridge to lessen and the legs urged towards each other with certain compressive spring force. A staple applicator supports and guides the staple and positions the tensioned staple with its pointed ends forward, adjacent an ejection port at the front of the applicator. A powered strike member is mounted for longitudinal movement and has a front end that will strike the rear of the tensioned staple with percussive force and eject it in tensioned configuration from the applicator.Type: ApplicationFiled: August 12, 2011Publication date: February 2, 2012Applicant: Dallen Medical, Inc.Inventor: Drew Allen

Patent number: 7232350Abstract: The watercraft described herein is a surfboard, skim board, dive board, or boat having a propelling fin driven by a standing surfer or boater with an upward and downward stroke which may be used to propel the watercraft by an upward and downward fin motion. The surfboard and dive board in particular are used on water and may be used to ride ocean swells and waves. The surfer or diver stands on the board and moves a vertical handle upwardly and down-ward. The lower end of this handle is pivotally attached to a parallel bar device having attachment means to the board at a forward end of the parallel bar device and having attachment means to a fin at the aft ward end of the parallel bar device. The fin is generally horizontal and is driven thru the water up and downwardly by the standing user and propels the board forward at higher rates of speed than can be achieved by prone-paddling.Type: GrantFiled: June 26, 2006Date of Patent: June 19, 2007Inventor: Drew Allen Krah
