Publication number: 20190030276Abstract: A breathing assistance apparatus adapted to deliver humidified gases at a desired level of humidity to a patient including a humidifier and a heated conduit is disclosed. The humidifier includes a controller which determines the flow rate of the gases and then determines the required power input to the humidifier to deliver the gases to the patient at the required patient humidity. This means the need for external sensors is dispensed with and thus the apparatus is simple and less bulky.Type: ApplicationFiled: June 18, 2018Publication date: January 31, 2019Inventors: Peter John Hunt, Mohammad Thudor, David Fraser Wixey, Stephen William McPhee

Patent number: 10130787Abstract: A breathing assistance apparatus adapted to deliver humidified gases at a desired level of humidity to a patient including a humidifier and a heated conduit is disclosed. The humidifier includes a controller which controls the humidifier, or the humidifier and the heated conduit to deliver the gases to the patient at the required humidity or temperature, without the requirement for sensors in the gases stream. The controller uses information already available to the controller, without the requirement for additional information to be provided by sensors in the gases stream. This means the need for sensors in the gases stream is dispensed with. A significant benefit is achieved as sensors are not required in the conduit and thus the apparatus is simple and less bulky.Type: GrantFiled: November 16, 2015Date of Patent: November 20, 2018Assignee: Fisher & Paykel Healthcare LimitedInventors: Peter John Hunt, Mohammad Thudor, David Fraser Wixey, Stephen William McPhee

Patent number: 10109080Abstract: Multi-sensor compressive imaging systems can include an imaging component (such an an RF, microwave, or mmW metamaterial surface antenna) and an auxiliary sensing component (such as an EO/IR sensor). In some approaches, the auxiliary sensing component includes a structured light sensor configured to identify the location or posture of an imaging target within a field of view of the imaging component. In some approaches, a reconstructed RF, microwave, or mmW image may be combined with a visual image of a region of interest to provide a multi-spectral representation of the region of interest.Type: GrantFiled: July 6, 2016Date of Patent: October 23, 2018Assignee: Duke UniversityInventors: David Brady, Tom Driscoll, John Hunt, Daniel Marks, Alexander Mrozack, Matthew Reynolds, David R.

Patent number: 9777963Abstract: A method and a system for a heat exchanger assembly are provided. The heat exchanger assembly includes one or more arcuate heat exchanger segments each including an inlet header configured to extend circumferentially about a circumference of an inner surface of a fluid flow duct, and an outlet header configured to extend circumferentially about the fluid flow duct. The heat exchanger assembly also includes a first serpentine heat exchanger tube extending between the inlet header and the outlet header and including a series of flow path segments having a gradually changing direction defined by a bend radius of the tube such that a direction of flow through the serpentine heat exchanger tube reverses between the inlet and the outlet headers and a second serpentine heat exchanger tube extending between the inlet header and the outlet header, the second serpentine heat exchanger tube co-planar with the first serpentine heat exchanger tube.Type: GrantFiled: May 15, 2015Date of Patent: October 3, 2017Assignee: General Electric CompanyInventors: Ramon Martinez, Benjamin Paul Breig, Keith Alan Joerger, Gregg Hunt Wilson, Matthew John Hunt, Donald Michael Corsmeier, Paul Charles Johnson

Publication number: 20170240901Abstract: Provided are siRNA molecules that are particularly efficient in their ability to reduce transcription and expression of TNF or IL-1? in canine macrophage and synovial cells. The siRNA molecules demonstrate improved silencing of TNF or IL-1? as compared to siRNA molecules disclosed prior to the present invention. These properties are demonstrated in accepted experimental models of osteoarthritis, and particularly canine osteoarthritis. The siRNA molecules of the invention, may be employed in pharmaceutical compositions for use in the prevention and/or reduction of osteoarthritis in dogs. The inventors have found that encapsulation of the siRNAs in small PLGA microspheres confers surprisingly advantageous properties.Type: ApplicationFiled: February 26, 2015Publication date: August 24, 2017Applicant: The University of LiverpoolInventors: John Hunt, John Innes

Patent number: 9669856Abstract: An accessory tray is connected to, or extends integrally from, a shopping cart handle and extends a limited distance forward from the handle. The tray extends forward above, but not significantly interfering with, the child-seat area of the cart. Preferably, the forward extremity is not directly connected or attached to the cart, but rather the tray is cantilevered from its rear end/edge fixed to/at the handle and extends otherwise unconnected forward from the handle. A forward tray portion may rest on, or be close to, an upper portion/end of the cart rear wall. The preferred tray is substantially planar, featuring a single, flat platform with an upending rim, wherein no part extends above said top level of the handle. The tray remains in place for nesting of multiple carts, and is received in a space between nested portions of the cart to which it is connected.Type: GrantFiled: May 19, 2016Date of Patent: June 6, 2017Inventor: Richard John Hunt

Publication number: 20170028149Abstract: An apparatus for supporting the head and neck for airway management and to facilitate the maintenance of a patent airway under anesthesia, for unconscious patients, and for any circumstance requiring a patent airway while the patient is lying on her side. The apparatus includes a head supporting surface, an adjustable neck supporting surface, and two adjustable jaw support arms to protrude the jaw forward and maintain ventilation while the patient is lying on either of his/her sides.Type: ApplicationFiled: July 22, 2016Publication date: February 2, 2017Inventors: Michael J. Pedro, Steven H. Cataldo, James Ellis, John Hunt, David M. Kane, Thomas Reilly

Publication number: 20170003389Abstract: Compressive imaging captures images in compressed form, where each sensor does not directly correspond with a pixel, as opposed to standard image capture techniques. This can lead to faster image capture rates due to lower I/O bandwidth requirements, and avoids the need for image compression hardware, as the image is captured in compressed form. Measuring the transformation of an emitted multimodal signal is one method of compressive imaging. Metamaterial antennas and transceivers are well suited for both emitting and receiving multimodal signals, and are thus prime candidates for compressive imaging.Type: ApplicationFiled: July 6, 2016Publication date: January 5, 2017Inventors: David Brady, Tom Driscoll, John Hunt, Daniel Marks, Alexander Mrozack, Matthew Reynolds, David R.

Patent number: 9450310Abstract: Surface scattering antennas provide adjustable radiation fields by adjustably coupling scattering elements along a wave-propagating structure. In some approaches, the scattering elements are complementary metamaterial elements. In some approaches, the scattering elements are made adjustable by disposing an electrically adjustable material, such as a liquid crystal, in proximity to the scattering elements. Methods and systems provide control and adjustment of surface scattering antennas for various applications.Type: GrantFiled: October 14, 2011Date of Patent: September 20, 2016Inventors: Adam Bily, Anna K.
