  • Publication number: 20240149286
    Abstract: A paint spraying system includes a paint spray gun, a spray tip removably coupled to the paint spray gun and having a tip orifice configured to output paint atomized in a spray pattern, the spray tip further including a readable element, a pump configured to pump the paint from a paint source to the paint spray gun, and a reader coupled to the paint spray gun and configured to read the readable element and to generate a signal indicative of an identifier of the spray tip. The system includes one or more processors configured to determine an identity of the spray tip based on the signal generated by the reader, identify a characteristic of the spray tip based on the identity of the spray tip, and generate a control signal based, at least in part, on the identified characteristic of the spray tip.

  • Publication number: 20240119298
    Abstract: In aspects of the disclosure, a method comprises training, by a computing system, a dynamics model of a cooperative multi-agent reinforcement learning (c-MARL) environment. The method further comprises processing, by the computing system, a perturbation optimizer to generate a state perturbation of the c-MARL environment, based on the dynamics model. The method further comprises selecting one or more agents of the c-MARL system as having enhanced vulnerability. The method further comprises attacking, by the computing system, the c-MARL system based on the state perturbation and the selected one or more agents.

  • Patent number: 11938497
    Abstract: A fluid spraying system includes a fluid applicator having a tip that atomizes a fluid. The fluid spraying system also includes a pump configure to pump the fluid from a fluid source to the tip and a control system. The control system identifies at least one characteristic of the tip or the fluid and communicatively couples to the pump. The control system also controls an operating characteristic of the fluid spraying system based on a characteristic of the tip or the fluid.

  • Patent number: 11885332
    Abstract: An operating method for a conveying device with an eccentric screw pump for conveying viscous construction materials comprising sensing a pressure of the construction material at an outlet of the eccentric screw pump when the eccentric screw pump is running and automatically switching off the eccentric screw pump if the pressure exceeds an upper limit value, otherwise continued operation of the eccentric screw pump. The method includes sensing a characteristic variable of the running eccentric screw pump and comparison of the characteristic variable with a first comparison variable, which is characteristic of operation with an open dispensing device and/or with a second comparison variable, which is characteristic of operation with a closed dispensing device, and switching off the eccentric screw pump if operation with a closed dispensing device is detected, otherwise continued operation of the eccentric screw pump.

  • Publication number: 20230349378
    Abstract: A fault-rectification method for an eccentric screw pump of a conveying apparatus for conveying viscous construction materials, comprising the steps of monitoring a start of a conveying operation of the eccentric screw pump by way of a characteristic-variable-monitoring program of a control device of the conveying apparatus, wherein a working-free program is executed by the control device of the eccentric screw pump if, for one or more characteristic variables. The characteristic-variable-monitoring program acquires characteristic-variable values which are stored, alone or in combination with one another, as fault values that indicate jamming of a rotor/stator unit of the eccentric screw pump, and wherein otherwise a conveying operation is begun. The eccentric screw pump is operated in the working-free program in such a way that an electric motor of a drive unit of the conveying apparatus is multiply alternately switched on and switched off.
