  • Publication number: 20240409248
    Abstract: An aircraft comprises an aircraft body, multiple battery packs positioned on the aircraft body, a load balancing circuit positioned on the aircraft body and connected to a battery power node, multiple motors positioned on the aircraft body and connected to the battery power node, and multiple bypass circuits positioned on the aircraft body. The load balancing circuit comprises multiple current delivery circuits. Each current delivery circuit is connected between one of the battery packs and the battery power node. Each of the bypass circuits is connected to the battery power node and one of the battery packs to provide a signal path from the battery power node to the respective battery pack that bypasses a respective current delivery circuit for regenerative current from one or more of the motors.

  • Publication number: 20240409228
    Abstract: Techniques for an unmanned ariel vehicle (UAV) having a closed-loop controller that is gain scheduled based on a trained machine learning model. The closed-loop controller could be a PID controller. Real-time data pertaining to the motor being controlled is input to the trained machine learning model. Examples of the real-time data includes, but is not limited to, motor current, motor voltage, and an estimate of motor thrust. The trained machine learning model may also input an error term of the closed-loop controller. Tuning constants for the closed-loop controller are derived based on the prediction from the machine learning model. Gain scheduling for the closed-loop controller may thus be performed “online” while the UAV continues on its mission. Controller gain scheduling may be performed to account for changes in a payload carried by the UAV.

  • Publication number: 20240411707
    Abstract: A plug-and-play Hub that provides an intermediary between an Unmanned Aerial Vehicle (UAV) and peripheral electronic devices. The Hub has a power and data interface to the UAV and peripheral ports that allow the peripheral electronic devices to connect to the Hub. The peripheral ports provide power to the peripheral electronic devices and also allow data communication between the Hub and the peripheral electronic devices. The Hub may detect when a peripheral electronic device has been plugged into a peripheral port and access communication protocol information and voltage level information by way of the peripheral port. A Hub voltage converter receives power from the UAV and converts the UAV power source voltage to a voltage level that is suitable for the various peripheral electronic devices. The Hub has a data hub that mediates data communication between the UAV and the various peripheral electronic devices.

  • Patent number: 12162094
    Abstract: Systems and methods are disclosed for an enclosure providing a sealed environment. The enclosure employs movable paneling that seals an area for a laser welding cell, while allowing access for an operator to load a workpiece in and unload the workpiece from a welding cell. Barriers are arranged on the enclosure, such that in a closed configuration activation of a pneumatic tube forces the barriers to extend toward a rotated paneling, such that the edges of the enclosure contact or overlap with the edges of the paneling to result in a light-tight seal. Presence of the fluid increases the pressure in the tube such that an external boundary of the tube expands, forcing the barrier toward the edges of the paneling, thereby closing the gap and providing a light-tight enclosure.

  • Publication number: 20240399058
    Abstract: An intravenous (IV) medication filter device can include a housing having a medication inlet, a medication outlet, and a gas vent. The filter device can include a hydrophobic gas filter inside the housing between the inlet and the gas vent and between the gas vent and the outlet. The hydrophobic gas filter can prevent medication received into the housing via the inlet from existing the housing via the gas vent. The hydrophobic gas filter can permit gas in the housing to exit the housing through the hydrophobic gas filter via the gas vent. The vent hole can have a shape that prevents sterilizing radiation directed at the gas vent from reaching the hydrophobic gas filter. Optionally, a porous plug may be inserted into the gas vent and/or a radiation shroud may be positioned over the gas vent to protect the gas vent from being damaged by the sterilizing radiation.

  • Patent number: 12157190
    Abstract: Disclosed example power supplies, user interfaces, and methods provide for monitoring, analysis and/or presentation of input power characteristics for a welding-type power supply and/or wire feeder. A welding system includes a power supply to deliver power to a welding torch based on one or more input power characteristics. The input power characteristics may correspond to received input power characteristics values during a welding procedure. The input power characteristics are responsive to the power demanded during the welding operation and may change accordingly. To maintain an accounting of the input power characteristics and their values as they change during the welding operation, control circuitry may receive information regarding the input characteristics, analyze the information, and/or generate presentable indicators for display on one or more graphical interfaces.

  • Patent number: 12151319
    Abstract: A method and apparatus for providing welding-type power derives motive power from a variable speed engine and driving a variable frequency generator with the motive power to provide a generator output. The generator output is preregulated to provide an intermediate signal, and the preregulating is controlled at least in response to feedback indicative of the welding-type output power. Welding-type output power is derived from the bus, and controlled at least in response to the welding feedback. Auxiliary output power is also derived from the bus, and controlled at least in response to feedback indicative of the auxiliary output power. The speed of the engine is controlled at least in response to one of the auxiliary feedback and the welding feedback. Energy produced by the engine that is not used as an output is stored by batteries. When the output exceeds the energy generated, the difference is supplied by the batteries.
