Patent number: 9763841Abstract: An apparatus is disclosed for adjusting an active length of a plurality of interwoven support elements of a weight bearing surface to conform to contours of a user's anatomy. The weight bearing surface overlies a frame to which the plurality of interwoven support elements are connected. The apparatus includes an adjustment mechanism connected to one of the plurality of interwoven support elements, wherein the adjustment mechanism is attached or releasably attached to the frame. The adjustment mechanism allows the active length of the connected interwoven support element to change as a user bears upon the weight bearing surface, thereby conforming the weight bearing surface to the contours of a user's anatomy. In another aspect, a method for adjusting an active length of at least some of a plurality of interwoven support elements of a weight bearing surface to conform to contours of a user's anatomy is disclosed.Type: GrantFiled: June 6, 2012Date of Patent: September 19, 2017Assignee: TAMARACK HABILITATION TECHNOLOGIES, INC.Inventors: J.

Patent number: 9241853Abstract: A substantially smooth, seamless managed friction material surface and apparatus for placement on a support surface between the support surface and a living being for preventing abrasion or decubitus ulcers in a living being. The managed friction material surface comprises a plurality of plies having a smooth side and a first, high friction zone and second, low friction zone. At least one adhesive ply is interposed partially between adjacent plies; and the plies are selectively bonded to form adjacent frictional zones of high and low friction. Unbonded plies are allowed to move substantially freely with respect to one another thus providing a lower friction zone. The apparatus comprises the managed friction material surface such that the bonded zone is configured for positioning remote the bony prominence and the unbonded zone for positioning proximate the bony prominence, seamlessly occupying different areas on the same side of the material surface.Type: GrantFiled: August 26, 2013Date of Patent: January 26, 2016Assignee: TAMARACK HABILITATION TECHNOLOGIES, INC.Inventors: J.

Patent number: 9133398Abstract: Methods for extracting a kerogen-based product from subsurface (oil) shale formations rely on chemically modifying the shale-bound kerogen using a chemical oxidant so as to render it mobile. The oxidant is provided to a formation fluid in contact with the kerogen in the subsurface shale. An alkaline material is also provided to the formation fluid to mobilize organic acids which are produced during oxidation of the kerogen. A mobile kerogen-based product which includes the organic acids is withdrawn from the subsurface shale formation and further processed to isolate the organic acids contained therein. These organic acids are valuable as hydrocarbon products for creating commercial products and a portion of these organic acids can also be used in the process for extracting the kerogen-based product from the subsurface shale formation.Type: GrantFiled: December 22, 2011Date of Patent: September 15, 2015Assignee: Chevron U.S.A.

Patent number: 8992771Abstract: Disclosed herein are methods for isolating heavy saturated hydrocarbons from a subsurface shale formation comprising kerogen and an extractible organics component. These methods can be used to provide a bright stock product. The process comprises extracting an extractible organics component from subsurface shale formations comprising kerogen and the extractible organics component in an inorganic matrix and isolating a heavy hydrocarbon fraction comprising saturated beta-carotene. The methods utilize a hydrocarbon solvent to at least partially solubilize the extractible organics component. Among other factors, these processes are based on the discovery that the extractible organics is composed of a heavy hydrocarbon component containing saturated beta-carotene. The saturated beta-carotene product is a valuable commercial product. The presently disclosed processes are more environmentally benign, more economical, and more efficient in producing commercial products and in providing access to kerogen.Type: GrantFiled: May 25, 2012Date of Patent: March 31, 2015Assignee: Chevron U.S.A.

Patent number: 8919347Abstract: An apparatus is disclosed for placement on a support surface between the support surface and a living being, wherein the living being has a bony prominence. The apparatus includes a first zone having a first coefficient of friction, the first zone being configured for positioning proximate the bony prominence. A second zone is adjacent the first zone, the second zone having a second coefficient of friction higher than the first coefficient of friction. The second zone is configured for positioning remote from the bony prominence. A method of preventing or healing decubitus ulcers includes positioning the bony prominence over the first zone and positioning an area remote from the bony prominence over the second zone.Type: GrantFiled: April 20, 2010Date of Patent: December 30, 2014Assignee: Tamarack Habilitation Technologies, Inc.Inventors: J.
