  • Patent number: 10837654
    Abstract: A user interface for a thermostat that controls a radiator valve can include a user input member that is movable from a home position to a set point increase or decrease position to increase or decrease a set point temperature of the thermostat. In some embodiments, a return mechanism returns the user input member to the home position after being released from one of the set point increase and decrease positions. The user interface can include an indicator panel and controller that controls the indicator panel to provide an indication of when the set point temperature of the thermostat is being adjusted. The user interface can also include a lockout controller that prevents further set point temperature adjustments using the user interface when the set point temperature differs from the environmental temperature by a specified amount.

    Abstract: A schedule determination device includes an acquisitor, a setter, and a determiner. The acquisitor acquires indexes of an operation schedule of a device and constraint conditions of the indexes. The setter sets a second range, which is narrower than a first range set in the operation schedule before a change, as a range for values of variables that establish constraint conditions of indexes of a new operation schedule. The determiner determines the operation schedule of the device, using the variable values within the second range.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for improving operational efficiency within a data center by modeling data center performance and predicting power usage efficiency. An example method receives a state input characterizing a current state of a data center. For each data center setting slate, the state input and the data center setting slate are processed through an ensemble of machine learning models. Each machine learning model is configured to receive and process the state input and the data center setting slate to generate an efficiency score that characterizes a predicted resource efficiency of the data center if the data center settings defined by the data center setting slate are adopted t. The method selects, based on the efficiency scores for the data center setting slates, new values for the data center settings.

  • Patent number: 10620597
    Abstract: Parameters are estimated for continuous time linear gray-box models using a fast sensitivity evaluation, which is a measure of how output of the model changes with changes in parameters. A two-step parameter estimation of non-linear models, such as a steady-state model and dynamical model, is performed. A parameter estimation algorithm is employed for estimation of non-linear model parameters via local approximation at different system operating levels or operating set-points. The parameter estimation task is improved by an efficient parameter estimation of linear, continuous-time, stochastic, gray-box models. It is further improved by using a two-step parameter estimation of non-linear, continuous-time, gray-box models. It is still further improved by employing the efficient parameter estimation algorithm for the non-linear gray-box models.
