  • Patent number: 11947518
    Abstract: A system for maintaining consistency of a data value using a probability includes an interface and a processor. The interface is configured to receive a data value for storing. The processor is configured to store the data value in a data element of a data structure and determine, using an adaptive filter, a probability of certainty associated with the data value. The probability of certainty associated with the data value depends on a time since the data value was updated. The adaptive filter provides as output the probability of certainty and store the probability of certainty associated with the data value in the data structure.

  • Patent number: 11727293
    Abstract: A predictive engine includes an optimizer and a predictor. The optimizer is configured to receive an observed dataset having inputs and multivariate responses and determine latent response variables based on the predictive inputs and the multivariate responses. The optimizer is further configured to select latent response variables, measure dependencies between multivariate responses, estimate coefficients that relate the input predictors to determined latent response variables, and correlate dependencies and coefficients with the latent response variables. The predictor is configured to generate a predictive distribution of probabilities for the latent variables, map the probabilities to multivariate responses, generate a predictive distribution of probabilities for the multivariate responses, and determine at least one optimized input from the multivariate responses.

  • Publication number: 20230243532
    Abstract: A controller for controlling HVAC equipment in a building includes a processing circuit configured to receive an occupancy schedule indicating at least one of a first occupied period or a last unoccupied period for a space in the building for a schedule period and receive a user input indicating the space should be purged based on occupancy. The controller selects, based on the user input, at least one of a pre-occupancy purge mode or a post-occupancy purge mode. The controller is further configured to control the HVAC equipment to ventilate the space for a purge duration prior to the beginning of the first occupied period in response to selecting a pre-occupancy purge mode, and ventilate the space for the purge duration at the beginning of the last unoccupied period in response to selecting a post-occupancy purge mode.

  • Patent number: 11268729
    Abstract: A method for providing environmental comfort includes obtaining measurements of a dry bulb temperature, a relative humidity, and an airflow rate for an indoor space, calculating an apparent temperature for the indoor space using the measurements, and generating a visualization comprising a comfort band and a value of each of the apparent temperature, the dry bulb temperature, the relative humidity, and the airflow rate for the indoor space plotted relative to the comfort band along independent axes. The method also includes controlling building equipment to drive the value of one or more of the apparent temperature, the dry bulb temperature, the relative humidity, or the airflow rate into the comfort band.
