Abstract: A controller for performing automated system identification. The controller includes processors and non-transitory computer-readable media storing instructions that, when executed by the processors, cause the processors to perform operations including generating a predictive model to predict system dynamics of a space of a building based on environmental condition inputs and including performing an optimization of a cost function of operating building equipment over a time duration to determine a setpoint for the building equipment. The optimization is performed based on the predictive model. The operations include operating the building equipment based on the setpoint to affect a variable state or condition of the space and include monitoring prediction error metrics over time. The operations include, in response to detecting one of the prediction error metrics exceeds a threshold value, updating the predictive model.

Abstract: A system for predicting HVAC equipment failure includes an actuator and a controller. The actuator is coupled to the HVAC equipment and configured to drive the HVAC equipment between multiple positions. The actuator includes a processing circuit configured to collect internal actuator data characterizing an operation of the actuator and a communications circuit coupled to the processing circuit. The communications circuit is configured to transmit the internal actuator data outside the actuator. The controller is configured to provide control signals to the actuator and receive the internal actuator data from the actuator. The controller includes a failure predictor configured to use the internal actuator data to predict a time at which the HVAC equipment failure will occur.

Abstract: A building management system (BMS) includes building equipment configured to provide samples of one or more data points in the building management system and a timeseries service. The timeseries service is configured to identify a first timeseries processing workflow that uses an input timeseries as an input and defines processing operations to be applied to the samples of the input timeseries, perform the processing operations defined by the first timeseries processing workflow to generate a first derived timeseries comprising a first set of derived timeseries samples, identify a second timeseries processing workflow that uses the first derived timeseries as an input and defines processing operations to be applied to the samples of the first derived timeseries, and perform the processing operations defined by the second timeseries processing workflow to generate a second derived timeseries comprising a second set of derived timeseries samples.

Abstract: A display device includes a front portion, a rear portion, a halo, and sides extending between the front portion and the rear portion. The front portion, the rear portion, and the sides form an enclosure. The halo includes a rim and an internal structure. The rim is positioned between the front portion and the rear portion. The internal structure is at least partially within the enclosure and includes a sweep portion and a receiving post. The receiving post and the sweep portion are configured to receive light emitted by one or more light emitting devices and at least one of guide, direct, diffuse, focus, and scatter light emitted by the one or more light emitting devices out of the display device.
