Publication number: 20120271222Abstract: A waveguide couples an acoustic source (such as an ultrasound transducer) to a cosmetic product (such as a liquid or gel-based skin care product) applied to the skin. In one representative embodiment, a distal surface of the waveguide is placed in contact with a relatively thin layer of skin care product that has been applied to the skin. Alternatively, the thin layer can be applied to the distal face of the waveguide, and then the waveguide placed on the skin. The cosmetic product may be formulated such that when ultrasound energy is directed into the cosmetic product via the waveguide, microspheres in the cosmetic product oscillate and increase the permeability of the skin to active beneficial agents included in the cosmetic product.Type: ApplicationFiled: February 17, 2012Publication date: October 25, 2012Applicant: JENU BIOSCIENCES, INC.Inventors: Justin Reed, Alexander Lebedev, Michael Lau, George Barrett, Irena Lebedev

Publication number: 20110159461Abstract: A power toothbrush (10) is disclosed having a handle (15), battery (12), ultrasonic drive circuit (14), motor (16), control unit (18), and toothbrush head (20). The toothbrush head includes bristles (26) and a waveguide (24) that is operatively connected to an ultrasonic transducer (22). The waveguide facilitates the transmission of acoustic energy into the dental fluid to achieve improved cleaning and stain removal and improved cleaning in interproximal and subgingival regions. In one embodiment an ultrasound transducer module (30) includes a plurality of piezoelectric elements (32, 34) that may be mechanically connected in series, and electrically connected in parallel. One or more contacts (36) connect the elements, and a waveguide structure (50). An impedance matching layer (38) may be provided between the waveguide and the ultrasonic transducer module. The waveguide may be formed from a relatively soft material, for example, a polymer having a hardness between 10 and 65 Shore A.Type: ApplicationFiled: March 14, 2011Publication date: June 30, 2011Applicants: WASHINGTON, UNIVERSITY OF, ULTREO, INC.Inventors: Pierre D.

Publication number: 20090318852Abstract: A waveguide couples an acoustic source (such as an ultrasound transducer) to a custom cosmetic product (e.g., a liquid or gel-based skin care product) applied to the skin. In one exemplary embodiment, a distal surface of the waveguide is placed in contact with a relatively thin layer of skin care product that has been applied to the skin. Alternatively, the thin layer can be applied to the distal face of the waveguide, and then the waveguide placed on the skin. The custom cosmetic product has been formulated such that when ultrasound energy is directed into the custom cosmetic product via the waveguide, bubbles included or formed in the custom cosmetic product oscillate, and increase the permeability of the skin to active beneficial agents included in the custom cosmetic product.Type: ApplicationFiled: June 18, 2009Publication date: December 24, 2009Applicant: JeNu Biosciences, Inc.Inventors: Justin Reed, Alexander Lebedev, Michael Lau, George Barrett, Irena Lebedev

Patent number: 5980246Abstract: This invention is an apparatus and method for monitoring and motivating user compliance for orthodontic headgear (24) of the type using a linear spring force module (22). The spring force module (22) includes first (38) and second opposite attachment members that are interconnected to provide spring tension when moved linearly apart. A position sensor (16)(18)(19) detects liner movement between the attachment members. A microprocessor (12) receives signals from the position sensor to determine wear duration, force magnitude, and whether such movement is sufficiently variable to be biological in origin or is attempted mimicry. Multiple determinations made by the processor are recorded over time to provide an evaluation of headgear wear compliance and to provide ongoing motivation for user compliance.Type: GrantFiled: March 24, 1998Date of Patent: November 9, 1999Assignee: The University of WashingtonInventors: Douglas S. Ramsay, Mani Soma, Chris Prall, George A. Barrett

Patent number: 5221089Abstract: A golf swing training aid kit comprising three golf practice aids, each of which can be used independently or all three may be used together. The kit, a brief-case sized box opens to form a platform. A self-contained collapsible pole is affixed therein and is adjusted for user height. The pole, held rigidly upright by means of struts and the golfer's weight while standing on a portion of said box, further comprising horizontal bars which provides passive limits to the motion of the golfer's hips.A second aid comprises a chest harness to which a lanyard is attached and whereby said lanyard's free end is looped around the center most part of a golf club's hand grip. Thereby, training the golfer in correct arm and wrist movement.The third related aid, a brightly colored ribbon having eyelets, for attaching ground anchors, for marking out the correct path to be followed by the club head during the golfer's swing.Type: GrantFiled: July 10, 1992Date of Patent: June 22, 1993Assignee: Gobar Enterprises, Inc.Inventor: George Barrett

Patent number: 4103515Abstract: In a driving mechanism of the kind having a drive part and a driven part with a shear-type coupling therebetween, the drive and driven parts have respective cylindrical surfaces which are spaced apart from, and substantially coaxial with, one another to define an annular space centered on the rotational axis of the parts. A fluid is disposed in the annular space to provide, at least in part, the said shear-type fluid coupling, and the spaced cylindrical surfaces together with the fluid therebetween constitute the sole bearing for the drive part. The fluid may contain an anti-creep additive. One of the said cylindrical surfaces, preferably the inner circumferential surface, may be constituted, at least in part, by a porous member impregnated with a shear-type fluid.Type: GrantFiled: August 6, 1975Date of Patent: August 1, 1978Assignee: Smiths Industries LimitedInventor: Edward George Barrett

Patent number: 4001673Abstract: A method of both testing all loops of a long serial magnetic bubble domain chip, and repairing the chip for automatic bypass of defective loops. Each repair station associated with each loop is sequentially loaded with a bubble domain. Then new domains are sequentially generated and positioned adjacent each loop. The domains initially loaded into the repair stations are shifted out in parallel for propagation along the loops. The new domains are then loaded in parallel into the repair stations. The domains propagated along the loops are read to determine defective loops, and form a basis for generating a repair pattern. The repair pattern is then loaded in parallel into the repair stations for sealing off defective loops.Type: GrantFiled: June 30, 1975Date of Patent: January 4, 1977Assignee: International Business Machines CorporationInventors: Gerald George Barrett, Louis Michael Hornung, Calvin Coolidge Jones, Jr.
