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: A display card for holding and dispensing articles includes rows of attached, protruding, tear-off tabs formed by cutting and bending a sheet which is semi-rigid and tearable. The tabs are generally keyhole-shaped with the head end of the keyhole being rounded and the stem end remaining attached to the card when the tabs are formed. By flexing, the rounded tab end is inserted through a lesser diameter hole in the article for display, thereby locking the article to the card. The article which may be in form of a product or package for a product may be removed from the card by pulling which causes the tab to tear until it separates from the card. A transverse slit in the card below each tab limits the extent of tearing. Articles remain attached regardless of card orientation until the article is intentionally removed.
