Publication number: 20060131832Abstract: A human-powered vehicle includes a driven wheel with a cantilevered hub, and a hand-operable crank for vehicle propulsion. In a wheelchair the hand cranks are supported on towers that are lowerable to fit under a desk or table. With the vehicle at rest, cranking motion of the crank in a first rotational direction propels the vehicle forward and cranking motion of the crank in a second rotational direction propels the vehicle backward. With the vehicle in forward motion, cessation of crank rotation allows free rotation of the wheel, and crank torque applied in a sense opposing forward vehicle motion applies a braking force to the wheel. An electric vehicle includes a transmission wheel hub that provides similar functions with an electric drive, such as for a wheelchair.Type: ApplicationFiled: November 1, 2005Publication date: June 22, 2006Inventors: Stuart Lindsay, David McMath, Mark Walker

Patent number: 7063124Abstract: An insert having a peripheral contact surface is received by a roller tube channel to engage a shade fabric. The insert is adjustable to compress the shade fabric within the channel. The insert may include a body having opposite side edges and at least one elongated slot. The insert member may include pivotable prongs or deflectable slot walls adjacent the slots. Pivoting of the prongs or deflection of the slot walls urges the body toward a channel side wall to compress the shade fabric. The insert may, alternatively, include a body having diametrically opposite portions respectively defining a curved outer periphery and a planar outer periphery, the body being wider between the curved portions. The insert is pivotable about an axis to grip the shade fabric between a channel side wall and one of the curved portions of the body.Type: GrantFiled: February 2, 2004Date of Patent: June 20, 2006Assignee: Lutron Electronics Co., Inc.Inventors: Mark A.

Publication number: 20050173080Abstract: A system for controlling a roller shade having a roller tube windingly receiving a shade fabric varies roller tube rotational speed for constant linear shade speed. The desired linear shade speed, roller tube diameter and shade fabric thickness and length are stored in a memory for use by a microprocessor. Preferably, the roller tube rotational speed is varied by the microprocessor depending on shade position determined by signals from Hall effect sensors. The microprocessor maintains a counter number that is increased or decreased depending on direction of rotation. Based on the counter number, the microprocessor determines shade position and a corrected rotational speed for the desired linear shade speed. Preferably, the microprocessor controls roller tube rotational speed using a pulse width modulated signal. The system may be used to control first and second roller shades having roller tubes of differing diameters or shade fabrics of varying thicknesses.Type: ApplicationFiled: February 9, 2004Publication date: August 11, 2005Inventors: Lawrence Carmen, David Dolan, Mark Walker

Publication number: 20050036100Abstract: A goggle, for use, for example, in paintball, comprises a lens 12, a body structure 14 for the lens and a strap 16. The body structure defines an ocular chamber 34 that covers the wearer's eyes, and an exhalation chamber 36 that covers the wearer's nose and mouth. An inlet plenum channel 42 leads from an inlet chamber 44 in the front of the goggle 10 up to the lower edge of the lens 12, and a fan 46 in the plenum channel 42 blows air from the inlet upwards across the inner surface of the lens 12. Air exhaled by the wearer leaves the exhalation chamber through outlet apertures 56 in the bottom of the mask, and is therefore directed away from the duct inlet chamber 44.Type: ApplicationFiled: April 21, 2004Publication date: February 17, 2005Applicant: NPF LimitedInventors: John Rice, Mark Walker

Patent number: 6845806Abstract: A weighting assembly for a roller shade fabric includes an elongated hem bar having opposite open ends and defining an internal cavity communicating with the open ends. A spline secured to an end of the fabric is slidingly received in a pocket defined within the cavity through one of the ends. The pocket includes an opening communicating with the rest of the cavity for passage of the fabric to an exterior through an elongated slot in the hem bar. After the fabric is wrapped on an exterior surface of the hem bar, a portion of the fabric is fed into the cavity through the slot to form a loop for slidingly receiving an elongated rod through one of the ends. The rod has a diameter that is greater than a width of the slot to prevent removal of the rod through the slot.Type: GrantFiled: January 6, 2003Date of Patent: January 25, 2005Assignee: Lutron Electronics Co., Inc.Inventors: Jason Scott Gottschall, Mark A.

Publication number: 20050003473Abstract: The present invention relates to a novel cytochrome P450-like enzyme (Aspergillus ochraceus 11 alpha hydroxylase) and an oxidoreductase (Aspergillus ochraceus oxidoreductase) isolated from cDNA library generated from the mRNA of Aspergillus ochraceus spores. When the cDNA encoding the 11 alpha hydroxylase was co-expressed in Spodoptera frugiperda (Sf-9) insect cells with the cDNA encoding human oxidoreductase as an electron donor, it successfully catalyzed the conversion of the steroid substrate 4-androstene-3,17-dione (AD) to 11 alpha-hydroxy-AD as determined by HPLC analysis. The invention also relates to nucleic acid molecules associated with or derived from these cDNAs including complements, homologues and fragments thereof, and methods of using these nucleic acid molecules, to generate, for example, polypeptides and fragments thereof. The invention also relates to the generation of antibodies that recognizes the A.Type: ApplicationFiled: July 28, 2004Publication date: January 6, 2005Inventors: Suzanne Bolten, Robert Clayton, Alan Easton, Leslie Engel, Dean Messing, John Ng, Beverly Reitz, Mark Walker, Ping Wang

Publication number: 20050005166Abstract: A document store delivers a document requested therefrom from a folder having rights information associated therewith. In response to a request for a copy of the document, rights data for the copy of the document is defined based on the rights information of the folder, and the copy of the document and the defined rights data thereof are published to result in a package with the rights data and the copy of the document encrypted according to a content key (KD) to result in (KD(copy)). The formed package is then delivered to the requester. The rights data can be discovered upon the requester attempting to render the package and such discovery triggers a request for a corresponding license based on such rights data. The license includes (KD) therein in a form available to the requester to decrypt (KD(copy)) if the requester satisfies the rights data.Type: ApplicationFiled: August 1, 2003Publication date: January 6, 2005Inventors: Pavel Kouznetsov, Jason Cahill, Lauren Antonoff, Kevin Brown, Moshe Lutz, Lutz Gerhard, Mark Walker

Publication number: 20040268137Abstract: A rights-managed document has protected content from an author thereof, whereby a recipient of the document can render the protected content with a corresponding license if the recipient satisfies terms set forth in the license. In the document, a storage portion has a message that the document is rights management protected, and a custom data portion has a section including the protected content. The recipient if enabled can render the protected content in the custom data portion and if not enabled can only review the storage portion having the message. An enabled recipient handles the received rights-managed document by recognizing that the document has the protected content in the custom data portion thereof, and discounting the storage portion of the document. Thus, the recipient examines the custom data portion of the document and proceeds based thereon to render the protected content in the custom data portion.Type: ApplicationFiled: June 27, 2003Publication date: December 30, 2004Inventors: Pavel Kouznetsov, Jason Cahill, David Ornstein, Lauren Antonoff, Mark Walker
