Publication number: 20240075314Abstract: A computing system comprising a central processing unit (CPU), and memory coupled to the CPU and having stored therein instructions that, when executed by the computing system, cause the computing system to execute operations to generate a radiation treatment plan. The operations include accessing a minimum prescribed dose to be delivered into and across the target, determining a number of beams and directions of the beams, and determining a beam energy for each of the beams, wherein the number of beams, the directions of the beams, and the beam energy for each of the beams are determined such that the entire target receives the minimum prescribed dose. The operations further include prescribing a dose rate and optimizing dose rate constraints for FLASH therapy, and displaying a dose rate map of the FLASH therapy.Type: ApplicationFiled: November 1, 2023Publication date: March 7, 2024Applicants: Varian Medical Systems, Inc., Siemens Healthineers International AG, Varian Medical Systems Particle Therapy GmbHInventors: Christel SMITH, Timo KOPONEN, Reynald VANDERSTRAETEN, Anthony MAGLIARI, Eric ABEL, Jessica PEREZ, Michael FOLKERTS, Deepak KHUNTIA

Patent number: 11912645Abstract: The invention is based on the discovery of a new bacterial compound with analgesic properties which could be used as a new tool for the treatment of pain disorders such as visceral pain. Studying the mechanisms implicated in analgesic properties of the probiotic Escherichia coli strain Nissle 1917 (EcN), inventors characterized, the amino fatty acids produced by EcN, which display the Ecn analgesic properties. One of these compounds inhibits the hypersensitivity to colorectal distension induced by capsaicin, which is a very powerful nociceptive compound and acts via the GABA B receptor. Furthermore, inventors demonstrate that this compound is able to cross the cellular epithelial barrier (such as the intestinal epithelium). Thus, the invention relates to a lipopetide compound, derived from gamma-aminobutyric acid. The invention also relates to a lipopeptide compound according to the invention for the treatment of treating pain disorder, such as somatic pain and visceral pain.Type: GrantFiled: April 27, 2018Date of Patent: February 27, 2024Assignees: INSERM (INSTITUT NATIONAL DE LA SANTÉ ET DE LA RECHERCHE MÉDICALE), CENTRE HOSPITALIER UNIVERSITAIRE DE TOULOUSE, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE—CNRS—, ECOLE NATIONALE VETERINAIRE DE TOULOUSE, UNIVERSITE PAUL SABATIER TOULOUSE III, INSTITUT NATIONAL DE RECHERCHE POUR L'AGRICULTURE, L'ALIMENTATION ET L'ENVIRONNEMENT, UNIVERSITE DE MONTPELLIER, ECOLE NATIONALE SUPERIEURE DE CHIMIE DE MONTPELLIERInventors: Nicolas Cenac, Justine Bertrand-Michel, Teresa Perez-Berezo, Thierry Durand, Jean-Marie Galano, Julien Pujo, Eric Oswald, Patricia Martin, Pauline Le Faouder, Alexandre Guy

Patent number: 11913673Abstract: An HVAC system includes an indoor heat-exchange coil disposed between a supply air duct and a return air duct. A damper is disposed in a re-circulation duct and is moveable between an open position and a closed position. A controller is configured to determine if the HVAC system is operating in a heating mode or an air-conditioning mode. Responsive to a determination that the HVAC system is operating in the air-conditioning mode, the controller is configured to determine if the variable-speed indoor circulation fan is operating at a minimum speed and if the relative humidity measured by the humidity sensor is above a pre-determined threshold. Responsive to a determination that the variable-speed indoor circulation fan is operating at the minimum speed and the relative humidity of the enclosed space is above the pre-determined threshold, the controller signals the damper to move to the open position.Type: GrantFiled: May 24, 2022Date of Patent: February 27, 2024Inventors: Rakesh Goel, Eric Perez, Eric Berg

Patent number: 11788761Abstract: An HVAC system includes an evaporator coil disposed between a supply air duct and a return air duct. A re-circulation duct fluidly couples the supply air duct and the return air duct. A damper is disposed in the re-circulation duct and is moveable between an open position and a closed position. A controller is operatively coupled to a variable-speed compressor, a variable-speed circulation fan, and the damper. Responsive to a determination that the variable-speed circulation fan is operating at the minimum speed and the suction pressure is above the pre-determined threshold, the controller signals the damper to move to the open position. Responsive to a determination that the variable-speed circulation fan is not operating at the minimum speed or the suction pressure is below the pre-determined threshold, the controller signals the damper to move to the closed position.Type: GrantFiled: February 22, 2021Date of Patent: October 17, 2023Assignee: Lennox Industries Inc.Inventors: Rakesh Goel, Eric Perez

Patent number: 11708981Abstract: An HVAC system with a reheat coil is described, the system includes a compressor, a micro-channel condenser and an evaporator. A reversing valve is connected to the compressor, the micro-channel condenser and the reheat coil. The reversing valve is used to direct the refrigerant from the compressor to the micro-channel condenser in a normal mode, and to direct the refrigerant from the compressor to the reheat coil in a reheat mode. The reversing valve can be switched from normal mode to reheat mode when a high pressure condition is detected at an input to the micro-channel condenser, and switched back from reheat mode to normal mode when the high pressure condition has resolved or an amount of time has passed. In the normal mode the refrigerant is returned from the reheat coil into a refrigerant line between the evaporator and the compressor through a restrictor.Type: GrantFiled: March 22, 2021Date of Patent: July 25, 2023Assignee: Lennox Industries Inc.Inventors: Colin Clara, Eric Perez, Walter E.

Publication number: 20210341190Abstract: Purge systems for heating, ventilation, air conditioning, and refrigeration (HVACR) circuits in chillers can use adsorbent and/or membranes to separate refrigerant from non-condensable gases, allowing the non-condensables to be exhausted while the working fluid can be recovered and returned to the HVACR circuit. The purge systems can include one or more separation chambers including either an adsorbent material or a selectively permeable membrane. The selectively permeable membrane can be solubility-based for its selectivity. Optionally, a pusher pump can be upstream of the separation chambers to pressurize the purge gas through the purge system, including in the separation chamber. The purge system can be controlled using a model correlating pressure differentials in the purge system with purge gas conditions such as non-condensable and working fluid concentrations.Type: ApplicationFiled: April 30, 2021Publication date: November 4, 2021Inventors: Ryan E.
