Patent number: 10920763Abstract: A diaphragm (18) includes a disk-shaped center planar portion (40) and a first lip (42) and a second lip (44) on the outermost edge of the disk shaped portion (40) and extending transversely to the planar disk portion (40). The first lip (42) is on a first side of the diaphragm (18) and the second lip (44) is on an opposite side of the diaphragm (18). A mounting portion (38) extends outward from the center of the face of the planar portion (40) on the first side of the diaphragm (18). For metering pump applications pumping harsh fluids, the diaphragm (18) is typically made from a fluoropolymer and in particular may be made from polytetrafluoroethylene (PTFE).Type: GrantFiled: May 19, 2017Date of Patent: February 16, 2021Assignee: Wanner Engineering, Inc.Inventors: David Poindexter, Neil Taylor

Patent number: 9076062Abstract: Techniques for searching in an image for a particular block of pixels that represents a feature are described herein. The techniques may include searching within an expanding search area to find a block of pixels that has a threshold amount of similarity to a block of pixels of a preceding image. Upon finding a block of pixels that satisfies the threshold, the techniques may search in the image along a path of increasing similarity to the block of pixels of the preceding image.Type: GrantFiled: November 21, 2012Date of Patent: July 7, 2015Assignee: Gravity Jack, Inc.Inventors: Benjamin William Hamming, Shawn David Poindexter

Patent number: 9058660Abstract: Techniques for searching in an image for a particular block of pixels that represents a feature are described herein. The techniques may include generating feature quality information indicating a quality of the feature with respect to blocks of pixels of the image. The feature quality information may be utilized to locate a block of pixels in a subsequent image that corresponds to the feature. For example, the feature quality information may be utilized to determine whether a block of pixels that has a threshold amount of similarity to the feature actually corresponds to the feature.Type: GrantFiled: November 21, 2012Date of Patent: June 16, 2015Assignee: GRAVITY JACK, INC.Inventors: Benjamin William Hamming, Shawn David Poindexter

Publication number: 20140140573Abstract: Techniques for tracking a pose of a textured target in an augmented reality environment are described herein. The techniques may include processing an initial image representing the textured target to generate feature relation information describing associations between features on different image layers of the initial image. The feature relation information may be used to locate features in different image layers of a subsequent image. Upon locating features in a highest resolution image of the subsequent image, the pose of the textured target may be determined for the subsequent image.Type: ApplicationFiled: November 21, 2012Publication date: May 22, 2014Applicant: GRAVITY JACK, INC.Inventors: Benjamin William Hamming, Shawn David Poindexter, Marc Andrew Rollins

Publication number: 20140079281Abstract: Architectures and techniques for augmenting content on an electronic device are described herein. In particular implementations, a user may use a portable device (e.g., a smart phone, tablet computer, etc.) to capture images of an environment, such as a room, outdoors, and so on. As the images of the environment are captured, the portable device may send information to a remote device (e.g., server) to determine whether augmented reality content is associated with a textured target in the environment (e.g., a surface or portion of a surface). When such a textured target is identified, the augmented reality content may be sent to the portable device. The augmented reality content may be displayed in an overlaid manner on the portable device as real-time images are displayed.Type: ApplicationFiled: September 17, 2012Publication date: March 20, 2014Applicant: GRAVITY JACK, INC.Inventors: Mitchell Dean Williams, Shawn David Poindexter, Matthew Scott Wilding, Benjamin William Hamming, Marc Andrew Rollins, Randal Sewell Ridgway, Damon John Buck, Aaron Luke Richey

Patent number: 5967736Abstract: A vehicle-based equipment handling device is constructed by installing tracks into the vehicle along which a carriage slides. A yoke is attached to the carriage at pivot points and is caused to pivot by the action of an extension cylinder. The yoke engages the equipment at its approximate center of gravity to allow easier positioning of the equipment. When the yoke has been actuated by the piston to lift the equipment, the carriage slides along the tracks to load the equipment into the vehicle. One particularly useful application of the equipment handling device is as a loading and unloading device for a portable x-ray machine.Type: GrantFiled: October 28, 1997Date of Patent: October 19, 1999Inventor: David A.
