Abstract: Disclosed are systems and methods that provide a novel thermostat system, which involves a hybrid line volt two-way thermostat configured with triode for alternating current (TRIAC) and relay components. The configuration and operational benefits of each thermostat type can be leveraged by the disclosed hybrid thermostat, which can provide a silent, efficiently operated thermostat system. Such system provides a resource efficient heating, ventilation and cooling control system that can reduce power consumption and thereby reduce costs, while maintaining a streamlined, operationally accurate framework for monitoring and managing the climate of a location (e.g., building, home, office, and the like).

Abstract: Systems and methods for speech recognition are provided. Some methods can include detecting a relative location of a user within one of a plurality of voice pickup areas of a multi-directional microphone array and the multi-directional microphone array activating a setting of the multi-directional microphone array based on the relative location of the user within the one of the plurality of voice pickup areas.

Abstract: An approach and system for receiving data from a thermostat in a building, treating the data as representative of a thermal response model or system, and determining a relationship between a rate of building internal temperature change and change in outdoor temperature to provide an indication of how well a building is insulated versus a thermal mass of the building.
