Patent number: 11946479Abstract: A wearable cooling device that is designed to rapidly restore and/or maintain a user's thermal comfort is provided. The disclosed wearable cooling device is versatile and may be affixed to or in contact with (or close proximity to) a variety of locations on a user's body, e.g., wrist, neck and ankle, among others. The wearable cooling device utilizes a forced air device, e.g., a fan, that blows air onto a wetted piece of media, e.g., fabric, which is in direct contact with a high thermally conductive element, e.g., copper or aluminum. The high thermally conductive element may be in contact with a user's skin or with a user's outer clothing. The wetted media is situated between the forced air device and the high thermally conductive element. When the forced air device is activated, the exhaust air passes onto and around the wetted media, which in turn cools the high thermally conductive element. As a result, the high thermally conductive element cools down the user.Type: GrantFiled: January 25, 2019Date of Patent: April 2, 2024Inventors: Rachel Schwimmer, Ashley Elizabeth Berg, Drew Eric Lilley, Nicholas Paul Demes, Daniel Charles Bravo Harris, Samuel Gaardsmoe

Publication number: 20240092703Abstract: The present invention is a liquid fertilizer comprising a calcium cyanamide component that is dissolved, co-applied, dispersed, or suspended in a solution of aqueous triazone urea. The combination of calcium cyanamide and triazone urea produces a slow release of nitrogen that requires fewer reapplications and is more effective than heretofore fertilizers. In one preferred embodiment, the fertilizer or plant treatment is further combined with a soil treatment including polycarboxylate acids and polyaliphatic acid salts in combination with potash to further enhance the properties of the fertilizer.Type: ApplicationFiled: November 22, 2023Publication date: March 21, 2024Applicant: KB8, Inc.Inventors: Broc Sondgroth, Eric Berg

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

Publication number: 20240060669Abstract: An HVAC system includes a high-pressure subsystem and a low-pressure subsystem. After determining that refrigerant leak diagnostics should be performed, a controllable valve is closed between a condenser and compressor of the HVAC system. The compressor then operates until a predetermined input refrigerant pressure is reached. After the predetermined input refrigerant pressure is reached, operation of the compressor is stopped. After stopping operation of the compressor and waiting at least a predetermined wait time, the pressure in the low-pressure subsystem of the HVAC system is monitored. A rate of change of the pressure in the low-pressure subsystem is determined. If the rate of change is negative and a magnitude of the rate of change is greater than a threshold value, a leak location is determined to be in the low-pressure subsystem.Type: ApplicationFiled: October 30, 2023Publication date: February 22, 2024Inventors: Payam Delgoshaei, Eric Berg

Patent number: 11644206Abstract: An HVAC system includes a heating element, a discharge air temperature sensor, and a return air temperature sensor. A controller of the HVAC system determines that the HVAC system has been operating in the heating mode for at least a predefined amount of time. The controller receives measurements of the discharge air temperature and the return air temperature. A temperature rise value is determined using the discharge air temperature and return air temperature. If the temperature rise value is less than a predefined minimum threshold value, the controller determines that a first fault of the HVAC system is detected and provides a corresponding alert. If the temperature rise value is greater than a predefined maximum threshold value, the controller determines that a second fault of the HVAC system is detected and provides a corresponding alert.Type: GrantFiled: January 24, 2022Date of Patent: May 9, 2023Assignee: Lennox Industries Inc.Inventors: Payam Delgoshaei, Glenn W.
