Patent number: 10890976Abstract: The invention is a human-computer interface device which permits the user to control their movement within a Virtual Reality (VR) simulation and receive lifelike physical feedback. The platform will allow the user to stand on top of it and control their movement within a VR Environment by leaning in a direction. The platform's weight sensor system will detect which direction the user is leaning and output that information to the PC. The PC will calculate send the feedback controls to the platform, causing it to move and vibrate as applicable. The physical feedback will result in a more realistic experience while reducing the motion sickness associated with existing VR systems. This invention has a modular design that allows the user to utilize attachments for additional purposes such as a driving simulator. Although the invention was initially designed for VR, any interactive computer entertainment system could benefit.Type: GrantFiled: September 21, 2018Date of Patent: January 12, 2021Inventor: Jeff Welch

Patent number: 10520957Abstract: A pressure regulating device including a valve body, an actuator assembly coupled to the valve body and including a diaphragm, a valve seat disposed in the valve body, a control assembly operatively connected to the diaphragm to move responsive to movement of the diaphragm, and a travel stop. The control assembly includes a control element that is movable, relative to the valve seat, between an open position, wherein the control element is spaced from the valve seat, and a closed position, wherein the control element sealingly engages the valve seat. The travel stop is configured to engage the control element to stop movement of the control element upon reaching the open position. The travel stop is adjustable to change the open position of the control element, such that a wide open flow capacity of the pressure regulating device can be adjusted.Type: GrantFiled: October 20, 2016Date of Patent: December 31, 2019Assignee: EMERSON PROCESS MANAGEMENT REGULATOR TECHNOLOGIES, INC.Inventors: Jeff Welch, II, Jake Buford, Matthew D. Reynolds, Christopher J. Hunt

Patent number: 8298215Abstract: A device for application of energy within a tubular bodily structure including an optical fiber couplable to a source of laser energy and a guidewire tip. The optical fiber has a laser emitting portion remote from the source of laser energy and a distal end. The guidewire tip is operably secured to the optical fiber and extends distally outwardly away from the distal end of the optical fiber. The guidewire tip assists in advancing the device through the tubular bodily structure.Type: GrantFiled: September 25, 2007Date of Patent: October 30, 2012Assignee: Vascular Solutions, Inc.Inventors: Kenneth Zinn, Jeff Welch, Howard Root

Patent number: 8252022Abstract: A closure device to be inserted at least partially through a blood vessel wall aperture in a blood vessel wall. The closure device includes at least two parts, an internal part and an external part. The internal part is adapted to be extended at least partially through the blood vessel wall aperture and into the lumen to at least partially block the blood vessel wall aperture. Each of the internal part and the external part consists essentially of a metal that biodegrades within a living being in a period of time that permits biological repair of the blood vessel wall in and around the blood vessel aperture.Type: GrantFiled: July 13, 2009Date of Patent: August 28, 2012Assignee: Vascular Solutions, Inc.Inventors: Tom Holman, Jeff Welch, Howard Root

Patent number: 8192456Abstract: A closure device to be inserted at least partially through a blood vessel wall aperture in a blood vessel wall, having at least two metal petals that can be inserted through the blood vessel wall aperture and into the lumen of the blood vessel. The petals are structured to prevent withdrawal through the blood vessel wall aperture when the length of the petal is generally aligned with the blood vessel wall. The metal petals have alignment features that tend to urge them into alignment relative to each other. The closure device includes a metal expansion member that is alterable from an unexpanded state to an expanded state. A bioabsorbable tensioning member interconnects the petals and the metal expansion member and is securable to the metal expansion member.Type: GrantFiled: July 13, 2009Date of Patent: June 5, 2012Assignee: Vascular Solutions, Inc.Inventors: Tom Holman, Jeff Welch, Howard Root

Patent number: 8083690Abstract: A guidewire converter for use in intravascular procedures along with a guidewire. The guidewire converter includes an elongate tubular structure defining a lumen having an inner diameter and a first outer diameter. The inner diameter of the lumen is sized to receive the guidewire for intravascular procedures. The guidewire converter includes a locking mechanism coupled to the elongate tubular structure that has a second outer diameter that is less than or substantially equal to the first outer diameter. Operation of the locking mechanism releasably secures the elongate tubular structure to the guidewire.Type: GrantFiled: September 4, 2008Date of Patent: December 27, 2011Assignee: Vascular Solutions, Inc.Inventors: Dean Peterson, Jeff Welch, Howard Root

Patent number: 7981091Abstract: A catheter to be passed over a guidewire, including a screw portion with a cylindrical hollow shaft and a helical thread portion extending outwardly from the hollow shaft. The screw portion is secured coaxially to a tubular portion formed from a substantially rigid material. The tubular portion has, along a portion of its length, at least two slits having a pattern geometry that limits torsional displacement. The catheter also includes a hub having a lumen joined substantially coaxially to the tubular portion.Type: GrantFiled: October 24, 2006Date of Patent: July 19, 2011Assignee: Vascular Solutions, Inc.Inventors: Howard Root, Jeff Welch, Jason Garrity, Dean Peterson

Publication number: 20080249649Abstract: A laser projector system includes a computer and a laser projector for projecting a laser image on a target surface, particularly in a factory or manufacturing environment. The computer is disposed remote from the laser project and provides the laser projector with a command and control signal. Communication between the computer and the laser projector is accomplished with power line network adapters. These adapters modulate an AC waveform to encode the command and control signal and other data. Thus, communication between the computer and the laser projector is accomplished without need for long runs of communication cables.Type: ApplicationFiled: April 3, 2008Publication date: October 9, 2008Applicant: VIRTEK VISION INTERNATIONAL INC.Inventors: Jeff Welch, Robert Sandness, Declan Whelan
