  • Patent number: 11093663
    Abstract: A method for designing a gearset meeting one or more design targets is provided. In particular, the design target is efficiency. Initially, a size and ratio of the gear set is specified. Gear friction coefficients are then calculated, and a value for a design target for the gear set is calculated. One or more of the macro-geometry parameters are modified, and the macro-geometry parameters are chosen such that the advantageous effects of one macro-geometry parameter on the design target counteract any disadvantageous effects of another macro-geometry parameter. This allows for a design for a gearset meeting the one or more design targets to be produced. The efficiency calculation includes the effect of a lubricant. Further design targets can include gear noise and gear durability.

  • Patent number: 11086276
    Abstract: A controller for a building system receives training data including input data and output data. The output data indicate a state of the building system affected by the input data. The controller pre-processes the training data using a first set of pre-processing options to generate a first set of training data and pre-processes the training data using a second set of pre-processing options to generate a second set of training data. The controller performs a multi-stage optimization process to identify multiple different sets of model parameters of a dynamic model for the building system. The multi-stage optimization process includes a first stage in which the controller uses the first set of training data to identify a first set of model parameters and a second stage in which the controller uses the second set of training data to identify a second set of model parameters.

  • Patent number: 11080438
    Abstract: A building-information management (BIM) system receives a set of wind vectors that identify wind speeds and directions at the surfaces of physical structures within a volume of air. The system stratifies the volume into vertically stacked layers that each contains similar wind vectors. Each layer is then divided horizontally into rectangular cells that each at least partially encloses a cluster of the structures. The system infers cell-specific relationships that relate physical attributes of the enclosed structures with the cell's incoming and outgoing airflows, from which the system builds a wind-propagation model for each cell. These cell-specific models are combined into a regional wind-propagation model that predicts how winds entering the volume will be propagated as outgoing wind vectors. The regional model is used by downstream modules of the BIM system to account for airflow effects when designing a planned building.
