Publication number: 20240139448Abstract: Methods and systems are disclosed related to determining whether there is a proper fit between a user interface and a face of a user. The methods and systems involve generating seal information associated with a seal region between a face of a user and a current user interface donned on the face of the user. The methods and systems are further related to analyzing the seal information to determine whether a leak exists in the seal region. If the leak exists, the systems and methods include analyzing the seal information to determine a location of the leak within the seal region. The systems and methods further include determining a new user interface to replace the current user interface based on the current user interface and the location of the leak.Type: ApplicationFiled: October 25, 2023Publication date: May 2, 2024Inventors: Nathan Zersee Liu, Albert Jack Greenwood Woffenden, Andrew Chan, Gregory Robert Peake, Jaiden James Choy

Patent number: 11471634Abstract: A patient interface including a seal-forming structure having a mouth portion that forms at least part of the mouth plenum and is configured to seal around the patient's mouth and a nasal portion that is configured to seal with the patient's nares. The nasal portion includes a nasal plenum positioned to receive pressurized gas from the mouth plenum. The seal-forming structure also includes a clip configured to connect the mouth plenum to the nasal plenum and act as a conduit for the flow of the pressurized gas from the mouth plenum to the nasal plenum. The clip includes a mouth portion end configured to engage the mouth portion, a nasal portion end configured to engage the nasal portion, and a pair of wings protruding from the nasal portion end into an interior of the nasal plenum so that the wings engage an interior surface of the nasal plenum.Type: GrantFiled: December 14, 2021Date of Patent: October 18, 2022Assignee: ResMed Pty LtdInventors: Deng Siong Lee, Robin Yew, Han Seong Chew, Teong Hong Chuah, Shannon Day, Christopher Daniel Parker, Vinay Manjunath, Nigel Paul Greig, Albert Jack Greenwood Woffenden, Chuan Foong Lee, Muhammad Adil Bin Abdul Halim, Andrew William Gillett

Patent number: 10046202Abstract: A motorized exercise apparatus for use with a power source comprising an exercise apparatus having a power supply configured to be connected to the power source. An electronically commutated motor is configured to drive the exercise apparatus. A controller is configured to connect a power supply to the motor to selectively energize the motor to drive the exercise apparatus and including an emergency stop feature. The controller selectively actuates the motor and disables activation of the motor when the emergency stop feature is actuated. An additional motor driven by the apparatus is configured to cause a dynamic braking action to slow the apparatus when the power source is disabled or when the emergency feature is actuated.Type: GrantFiled: June 20, 2016Date of Patent: August 14, 2018Assignee: Digital Concepts of Missouri, Inc.Inventors: James R.

Publication number: 20180180297Abstract: A convection oven having a vapor collection system; water injection system; easily accessible electrical components; and a variable-speed, reversible blower is disclosed. The vapor collection system collects vapor from the cooking chamber during a cooking event, condenses the vapor, and drains the condensed vapor. The water injection system injects water for impact against a blower wheel for dispersion into the air circulating through the cooking chamber. The electrical components are housed within a housing that in a closed position conceals the components and in a closed position exposes the components for easy access. The rotational speed and direction of the variable-speed, reversible blower is controlled during a cooking event according to predetermined speed curves which may include one or more reversal events to achieve more uniform cooking of food. A main controller is programmable via an operator input (e.g., liquid crystal display touch screen) to control operating parameters of the oven.Type: ApplicationFiled: February 22, 2018Publication date: June 28, 2018Inventors: Jack Greenwood, Robert J. Reese
