Abstract: Disclosed herein are systems and methods for identifying welding anomalies and discontinuities in stud welding using AI models. Instead of conventional welding accuracy methods (e.g. destructive and/or image generation methods) a processor may communicate with one or more sensors associated with a joining machine to retrieve joining data and attributes. The processor may then execute an AI model that is trained based on previously performed stud welding, their corresponding welding attributes, and their corresponding discontinuities and/or anomalies. The processor may execute the AI model using data retrieved from the sensors and may calculate a likelihood of a discontinuity and discontinuity attributes, such as, location, depth, and the like. The processor may also execute a second AI model to identify an appropriate course of action to remedy the identified/predicted discontinuity.

Abstract: Composite bi-fold doors and other composite closures having improved assemblies are described, wherein the assemblies provide enhanced strength and durability of the doors and their construction while simultaneously maintaining their aesthetics. Additional improved bi-fold door and semi-solid door assemblies are also provided, which allow for the dimensional adjustment of the height of the doors by the installer as necessary, while simultaneously maintaining the structural integrity of the doors following the height adjustment.

Abstract: Particular embodiments relate generally to vibration isolation systems and tuned mass dampers. In one embodiment, a vibration isolation system may include a supporting base, an isolated mass, at least one air mount, a control valve, a compressed air supply, and a supervisory controller. The air mount is positioned between the isolated mass and the supporting base. The control valve is pneumatically coupled to the air mount, the compressed air supply and the atmosphere, and is operable to adjust a flow of air to and from the air mount. The supervisory controller receives a mass relative height signal, a mass relative velocity signal, and a mass relative acceleration feedback signal corresponding to a relative acceleration of the isolated mass or a pressure of the air mount.

Abstract: A system for actively damping the low-frequency coloration of sound in a listening room is provided comprising an acoustic wave sensor, an acoustic wave actuator, and an electronic feedback controller. The listening room defines at least one mode of low-frequency coloration. The acoustic wave actuator is substantially collocated with the acoustic wave sensor within the listening room. The electronic feedback controller is operative to generate a signal at its output by applying a feedback controller transfer function. The feedback controller transfer function comprises a second order differential equation including a first variable representing a predetermined damping ratio and a second variable representing a tuned natural frequency and creates a 90 degree phase lead substantially at the resonant frequencies of at least one mode of low-frequency coloration. The feedback controller output signal represents a rate of change of volume velocity to be produced by the acoustic wave actuator.

Abstract: A system for actively damping low frequency noise in an enclosure is provided comprising an acoustic wave sensor, and acoustic wave actuator, and an electronic feedback loop. The acoustic wave actuator is substantially collocated with the acoustic wave sensor within an enclosure. The electronic feedback loop is operative to generate a signal at its output by applying a feedback loop transfer function. The feedback loop transfer function comprises a selected second order differential equation including a first variable representing a predetermined damping coefficient and a second variable representing a tuned natural frequency. The transfer function defines a frequency response having a characteristic maximum gain substantially corresponding to the value of the tuned natural frequency and creates a 90 degree phase lead substantially at the tuned natural frequency. The feedback loop output signal represents a rate of change of volume velocity to be produced by the acoustic wave actuator.
