Patent number: 9243813Abstract: A vent for a building has a cover attached to a base. The base has an aperture permitting gas to pass. A moisture directing means on an underside of the cover directs moisture move under the influence of gravity to fall outside of the aperture. The cover may include a slanted side wall portion, with the aperture positioned with its center displaced from the center of the cover toward the slanted side. The base may include a pair of moisture deflecting features along at least a portion of one of the nonslope sides to prevent moisture flowing along the base from within an area on the base covered by the cover to outside of the covered area at the nonslope sides. The base may also include a water deflecting ridge on its underside positioned between a downslope edge and the aperture to deflect water away.Type: GrantFiled: November 8, 2011Date of Patent: January 26, 2016Assignee: Canplas Industries Ltd.Inventors: James Brian Mantyla, Timothy Duane Bach, Donna Maria Burtch, Kent Douglas Proctor

Patent number: 9141002Abstract: Substrate support apparatus and methods are disclosed. Motion of a substrate chuck relative to a stage mirror may be dynamically compensated by sensing a displacement of the substrate chuck relative to the stage mirror and coupling a signal proportional to the displacement in one or more feedback loops with Z stage actuators and/or XY stage actuators coupled to the stage mirror. Alternatively, a substrate support apparatus may include a Z stage plate a stage mirror, one or more actuators attached to the Z stage plate, and a substrate chuck mounted to the stage mirror with constraints on six degrees of freedom of movement of the substrate chuck. The actuators impart movement to the Z stage in a Z direction as the Z stage plate is scanned in a plane perpendicular to the Z direction. The actuators may include force flexures having a base portion attached to the Z stage plate and a cantilever portion extending in a lateral direction from the base portion.Type: GrantFiled: March 4, 2013Date of Patent: September 22, 2015Assignee: KLA-Tencor CorporationInventors: Salam Harb, Kent Douglas, Marek Zywno, James Haslim, Jon Hamilton

Publication number: 20140342658Abstract: There is disclosed a roof vent having rain control means to reduce rain water splashing into the opening in a roof vent. The baffle has a number of ridges or channels that direct rain water into a number of droplet pathways. The falling water creates a rain curtain that deflects rain water that enters into the roof vent from travelling into interior of the building. At the base of the roof vent is one or more splash deflectors that changes the angle of water impacting the base of the roof vent to limit the amount of deflected water that can enter into the opening in the roof vent. The rain curtain and one or more splash deflector may act in concert to further divert rainwater.Type: ApplicationFiled: February 1, 2013Publication date: November 20, 2014Applicant: Canplas Industries Ltd.Inventors: Richard Alan Parkinson, Donna Maria Burtch, Timothy Duane Bach, James Brian Mantyla, Kent Douglas Proctor, James Edwin Teskey

Patent number: 8543345Abstract: The present invention is directed to an electrochemical tool consisting of a potentiostat and user replaceable sensors and/or electrodes accompanied by an electronic memory that contains information that directs the potentiostat operation. The potentiostat is designed to operate with sensors employing a user customizable sensor and/or electrode memory. The customizable memory allows storing of information from a user and/or manufacturer related to a unique sensor identifier, calibration information, and/or an operational sequence to be employed by the potentiostat to properly operate the sensor and/or electrodes. A further aspect is to provide an electrode with pre-programmed electrode attributes.Type: GrantFiled: August 4, 2009Date of Patent: September 24, 2013Assignee: ADA Technologies, Inc.Inventor: Kent Douglas Henry

Patent number: 8329024Abstract: A method and apparatus measures the presence of total residual oxidant species in aqueous environments. More specifically, the apparatus is operable to measure hypohalites (e.g., hypochlorite and hypobromite) in water containing halide salts using electrochemistry. The apparatus can be a sensor having four electrodes—a reference electrode, a working electrode, and two auxiliary electrodes. The fourth electrode, i.e., the second auxiliary electrode, can be used to generate ionized water near and in contact with the working electrode. The ionized water can clean the working electrode to minimize effects due to scaling or biofilm formation. As such, the working electrode does not need the capability to clean itself. Thus, other elements, originally believed to be unsuitable for use in saline aqueous environments, can be used for the electrodes, for example, gold.Type: GrantFiled: July 6, 2010Date of Patent: December 11, 2012Assignee: ADA Technologies, Inc.Inventor: Kent Douglas Henry

Publication number: 20050254698Abstract: A method and apparatus, and variations of each, for inspecting a wafer defining at least one die thereon is disclosed. The present invention first obtains the electronic image equivalent of two die, and then determines the x and y offset between those electronic images. Prior to inspection for defects, those two electronic images are aligned by adjusting the x and y positions of one electronic image of one die with respect to the electronic image of the other die. Once that is accomplished, the those electronic images are compared to detect any defects that may exist on one of the die.Type: ApplicationFiled: July 13, 2005Publication date: November 17, 2005Inventors: Scott Young, Roger Kroeze, Curt Chadwick, Nicholas Szabo, Kent Douglas, Fred Babian
