  • Publication number: 20250137675
    Abstract: A building system of a building, the building system including one or more memory devices storing instructions thereon that, when executed by one or more processors, cause the one or more processors to update a building condition of an HVAC system of a space in a building at a time t1, wherein the building condition is updated from a default building condition. The instructions when executed by the one or more processors, cause the one or more processors to update the building condition of the space at a time t2 and receive an occupant response of an occupant from the space. The instructions when executed by the one or more processors, cause the one or more processors to update an artificial intelligence (AI) model based on the occupant response and generate, using the AI model, one or more actions for the HVAC system of a plurality of spaces.

  • Publication number: 20220163038
    Abstract: Disclosed is a unique Triple bullet (shaped) magnet in wing gate design with a specific array with an electromotor assembly, which is made up of up to 4 rotating triple bullet magnet arms spaced equally apart, at 90 degrees for the 4 arm triple bullet magnet, in rotary motion, maintaining motion within the 5 spatially fixed wing gates regarding their orientation in the circle, but laterally mobile. The electromotor assembly includes receiving power from the specific solar panel array, stored and utilized power maintained and transferred into and out of the supercapacitor bank, and utilizes a one-way gate to guide electrical power from the solar type power array to the supercapacitor bank. The supercapacitors also utilize energy production from the rotary engine component through an electromagnetic generator and other corresponding energy conservation. These provide power to the electronics in the system or machine, as well as drive fans or otherwise.

  • Patent number: 11293416
    Abstract: The present disclosure provides generally for a fluid-dispensing device. More specifically, the present disclosure provides for a precision fluid-dispensing device that may deliver a predefined volume of fluid quickly and reliably. In some aspects, the precision fluid-dispensing device may be used to deliver a fluid to a receiving container, such as in a manufacturing line, as a non-limiting example. In some embodiments, the precision fluid-dispensing device may dispense very accurate volumes of fluid using the head pressure of the fluid from an elevated reservoir or pressurized fluid supply. In some implementations, the precision fluid-dispensing device may dispense fluid gently and quickly, which may allow for handling of fluids that may be sensitive to agitation or mixing.
