  • Publication number: 20250044780
    Abstract: Methods and systems are provided for configuring a plant assembly station at a vehicle manufacturing plant. Plant sensor data generated by a plant sensor system is received at a plant assembly configuration system. The plant sensor data is associated with a configuration of a first plant assembly station at a vehicle manufacturing plant. A digital twin of the first plant assembly station is generated based in part on the plant sensor data. A determination is made regarding whether the configuration of the first plant assembly station is in accordance with operational regulations based on a simulation-based assessment of the digital twin of the first plant assembly station. An operability status of the configuration of the first plant assembly station is generated based on the determination.

  • Patent number: 11912547
    Abstract: A system includes a platform to support a vehicle on a first side of the platform and a passive motion device arranged on a second side of the platform, opposite the first side, to move upon actuation. A mechanical actuator actuates the passive motion device based on movement of one or more wheels of the vehicle to change a position of the vehicle. The position of the vehicle relative to the platform is unchanged and the passive motion device is actuated by only the movement of the one or more wheels of the vehicle to change the position of the vehicle.

  • Patent number: 8606421
    Abstract: Methods of forecasting and modulating energy consumption at a production facility are provided. The amounts of energy consumed during production and non-production times are used to obtain highly accurate hourly energy use rates for different energy use activities which are used to estimate the amount of energy that will be consumed during a subsequent time period. The forecasting and modulating methods provide a more tailored estimate of energy usage that prevents the unnecessary expense of using on-demand energy without the benefit of a pre-purchased or pre-reserved discount. The forecasting and modulating methods also help prevent overestimation of the amount of energy used.
