  • Patent number: 12450139
    Abstract: Systems and methods for dynamically managing application programming interface (API) resource allocation and rate limits are disclosed herein. An API monitoring system receives usage monitoring data for APIs, where each API is associated with a corresponding rate limit. A machine learning model processes the usage monitoring data to predict time periods when API usage is expected to exceed rate limits. Based on determining that a matching time period has been predicted for a subset of oversubscribed APIs, the system retrieves resource allocation data and identifies undersubscribed APIs from which resources may be reallocated. The system dynamically adjusts memory, processing power, or network bandwidth allocations and updates corresponding rate limits to balance API demand. By proactively reallocating resources and adjusting rate limits, the system optimizes API performance, prevents failures, and ensures efficient utilization of computing resources.

  • Patent number: 11892365
    Abstract: A system that includes a driving component, such as a motor, and a driven component. The system also includes a torque limiter positioned between the driving component and the driven component. The driving component is coupled to a driving end of the torque limiter and the driven component is coupled to a driven end of the torque limiter. The torque limiter is configured to assume a normal operating state with no slippage between the driving and driven ends of the torque limiter and an over-torque operating state with slippage occurring between the driving and driven ends of the torque limiter. The torque limiter includes a metal moving part that assumes a first position when the torque limiter is in the normal operating state and a second position different than the first position when the torque limiter assumes the over-torque operating state. An inductive proximity sensor monitors the position of the metal moving part.

  • Publication number: 20180159404
    Abstract: An air-cooled electric motor having a parallel circuit of two fan wheels is discloses. The electric motor includes a belt tensioner attached on a fixed bearing side of the electric motor, an inverter housing arranged on a floating bearing side of the electric motor, and a fan system having a first fan wheel on the floating bearing side and a second fan wheel on the fixed bearing side. The first fan wheel suctions a cooling air volume flow from the environment radially inward and blows a first part of the suctioned air volume flow radially outward via a stator winding head on the floating bearing side, from the electric motor back into the environment. The second fan wheel suctions a second part of the air volume flow and blows it radially outward via a stator winding head on the fixed bearing side, from the electric motor back into the environment.
