20130024799 | DYNAMIC DEVICE-ASSOCIATED FEEDBACK INDICATIVE OF RESPONSIBLE DEVICE USAGE - Methods and devices for controlling a heating, ventilation, and air conditioning (HVAC) system by a thermostat are provided. Input can be received from a user via a thermostat, the input being indicative of an adjustment of an HVAC-related setting. On a real-time basis, the HVAC-related setting that is being adjusted can be compared against a feedback criterion designed to indicate a circumstance under which feedback is to be presented to the user. The circumstance can be indicative of an achievement of a HVAC-related setting of a predetermined responsibility level with respect to an energy usage of the HVAC system. Upon a real-time determination that the feedback criterion is satisfied, visual feedback can be caused to be presented to the user in real-time. The real-time feedback can include a visual icon having a visual appeal corresponding to a desirability of the satisfaction of the feedback criterion. | 01-24-2013 |

20130103621 | INTELLIGENT CONTROLLER PROVIDING TIME TO TARGET STATE - The current application is directed to intelligent controllers that continuously, periodically, or intermittently calculate and display the time remaining until a control task is projected to be completed by the intelligent controller. In general, the intelligent controller employs multiple different models for the time behavior of one or more parameters or characteristics within a region or volume affected by one or more devices, systems, or other entities controlled by the intelligent controller. The intelligent controller collects data, over time, from which the models are constructed and uses the models to predict the time remaining until one or more characteristics or parameters of the region or volume reaches one or more specified values as a result of intelligent controller control of one or more devices, systems, or other entities. | 04-25-2013 |
20130103622 | AUTOMATED CONTROL-SCHEDULE ACQUISITION WITHIN AN INTELLIGENT CONTROLLER - The current application is directed to intelligent controllers that initially aggressively learn, and then continue, in a steady-state mode, to monitor, learn, and modify one or more control schedules that specify a desired operational behavior of a device, machine, system, or organization controlled by the intelligent controller. An intelligent controller generally acquires one or more initial control schedules through schedule-creation and schedule-modification interfaces or by accessing a default control schedule stored locally or remotely in a memory or mass-storage device. The intelligent controller then proceeds to learn, over time, a desired operational behavior for the device, machine, system, or organization controlled by the intelligent controller based on immediate-control inputs, schedule-modification inputs, and previous and current control schedules, encoding the desired operational behavior in one or more control schedules and/or sub-schedules. | 04-25-2013 |
20130173064 | USER-FRIENDLY, NETWORK CONNECTED LEARNING THERMOSTAT AND RELATED SYSTEMS AND METHODS - A user-friendly, network-connected learning thermostat is described.

The thermostat also includes a rechargeable battery and power-stealing circuitry adapted to harvest power from HVAC triggering circuits. By maintaining the microprocessor in a “sleep” state often compared to the lower-power microcontroller, high-power consuming activities, such as learning computations, wireless network communications and interfacing with a user, can be temporarily performed by the microprocessor even though the activities use energy at a greater rate than is available from the power stealing circuitry. | 07-04-2013 |
