Patent number: 10980963Abstract: A respiratory mask made of cloth and having a nasal portion and an air delivery arrangement is disclosed. The cloth that is used is impermeable to air and is designed to provide a mask that will inflate to provide therapy to patients at a positive pressure. The air delivery arrangement provides air at positive pressure to the body of the mask via a hermetic seal.Type: GrantFiled: April 25, 2018Date of Patent: April 20, 2021Assignee: Circadiance LLCInventors: David Groll, Ronnie E. Mahofski, Nadine Scandinaro, Eric S. Nachreiner

Patent number: 10814085Abstract: A mask for use in delivering air at a therapeutic pressure to a patient in need of therapy receives air from an air tube into an inelastic cloth mask portion that is attached to an interface portion constructed of an elastic material. The interface portion is a three dimensional structure that is attached at its edges to the mask portion and has a nose hole for receiving the patient's nose. When air is delivered the elastic interface portion pillows out and forms a seal against the patient's face. To assist with the seal, a structural assistance member may optionally be disposed on the interface portion above the nose hole so that it can be adjusted in the area of the bridge of the patient's nose.Type: GrantFiled: November 30, 2017Date of Patent: October 27, 2020Assignee: Circadiance LLCInventors: David Groll, Nadine Scandinaro, Alexander C. De Poix

Patent number: 9308343Abstract: The invention is a frameless, disposable cloth body for use with a respiratory mask, such as for continuous positive airway pressure therapy for those having sleep apnea. The cloth body is inflatable and moisture-vapor breathable and has an inner side having a nasal interface portion disposed on it and an outer side, and also has a circular aperture formed in a central location on the body, sized to sealingly receive an air delivery arrangement. The cloth body also has a pair of wings on opposite sides with slits arranged at optimal angles for receiving headgear straps.Type: GrantFiled: March 14, 2013Date of Patent: April 12, 2016Assignee: Circadiance, LLCInventors: David Groll, Ronnie E.

Patent number: 8738180Abstract: A system for a work cell having a carrier that moves a product along an assembly line includes an assembly robot, sensor, and controller. An arm of the robot moves on the platform adjacent to the carrier. The sensor measures a changing position of the carrier and encodes the changing position as a position signal. The controller receives the position signal and calculates a lag value of the robot with respect to the carrier using the position signal. The controller detects a requested e-stop of the carrier when the arm and product are in mutual contact, and selectively transmits a speed signal to the robot to cause a calibrated deceleration of the platform before executing the e-stop event. This occurs only when the calculated tracking position lag value is above a calibrated threshold. A method is also disclosed for using the above system in the work cell.Type: GrantFiled: December 14, 2011Date of Patent: May 27, 2014Assignee: GM Global Technology Operations LLCInventors: Jianying Shi, David Groll, Peter W. Tavora

Patent number: 8700205Abstract: A moving stop station includes a vehicle carrier configured to move a vehicle along an assembly line, an assembly platform disposed adjacent to the assembly line, and a synchronizer in communication with the vehicle carrier and the assembly platform. The synchronizer is configured to synchronize the motion of the assembly platform with the motion of the vehicle carrier as the vehicle carrier moves along a length of the assembly line, and includes a sensor, processor, and actuator. The sensor is configured to sense the position of the vehicle carrier and to generate a position signal corresponding to the sensed position. The processor is configured to receive the position signal and selectively provide a synchronization signal in response, and the actuator is configured to receive the synchronization signal and synchronize the motion of the vehicle carrier and the motion of the assembly platform in response.Type: GrantFiled: August 5, 2011Date of Patent: April 15, 2014Assignee: GM Global Technology Operations LLCInventors: Robert J. Scheuerman, Rick F. Rourke, Jianying Shi, Peter W. Tavora, David Groll
