Abstract: A system includes a plurality of thermostats corresponding to a plurality of HVAC systems that serve a plurality of spaces and a computing system communicable with the plurality of thermostats via a network. The computing system is configured to, for each space of the plurality of spaces, obtain a set of training data relating to thermal behavior of the space, identify a model of thermal behavior of the space based on the set of training data, perform a model predictive control process using the model of thermal behavior of the space to obtain a temperature setpoint for the space, and provide the temperature setpoint to the thermostat corresponding to the HVAC system serving the space. The plurality of thermostats are configured to control the plurality of HVAC systems in accordance with the temperature setpoints.

Abstract: The present invention is a multi-disc spinning assembly for a bicycle having a narrow flange hub, a first disc, a second disc and a set of bearings. The narrow flange hub supports a wheel. The first disc comprises a series of brackets around the periphery of a backside of the first disc for mounting the first disc to a rim of the wheel; and one or more openings. The second disc is located between the first disc and a flange of the narrow flange hub. The set of bearings connects to the second disc and the narrow flange hub, such that the set of bearings allows the second disc to rotate in a single direction at a velocity independent of the wheel velocity after maximum velocity of the wheel has been attained.
