Abstract: This patent specification relates to methods and systems that can detect over cycling conditions that exist in an HVAC system. The over cycling condition can be caused by overheating of a forced air heating system or furnace of the HVAC system control. When the furnace overheats, a thermally actuated limit switch within the furnace may cut off power to a heat generation apparatus. The limit switch can reconnect the power to the heat generation apparatus after it has cooled down, at which point the thermostat control system may issue another heating call to continue heating the enclosure so that it reaches the desired temperature. If the overheat condition persist, then the thermally actuated switch will cut power, resulting in repeated power cycling. The detection system and methods can monitor these power loss events and use them as data points for determining whether an alert condition exists within the HVAC system.

Abstract: Various arrangements are presented for monitoring a resident of a residence. A confidence assessment may be performed based on a plurality of smart home devices in the residence. The residence may be identified as eligible for monitoring of the resident based on the confidence assessment. A learning process may be performed to create an ordinary behavior model. Data that is received from the plurality of smart home devices may be monitored to identify data indicative of behavior considered unusual based on the ordinary behavior model.

Abstract: A thermostat may include a plurality of heat-generating components; a plurality of first temperature sensors, each of the plurality of first temperature sensors being disposed next to a corresponding one of the plurality of heat-generating components; a second temperature sensor that is disposed away from the plurality of heat-generating components; and a memory device storing a coefficient matrix. The thermostat may also include one or more processors that combine a plurality of inputs to calculate an ambient temperature for an enclosure in which the thermostat is installed, the plurality of inputs including readings from the plurality of first temperature sensors, readings from the second temperature sensor, and the coefficient matrix.

Abstract: The current application is directed to intelligent controllers that use sensor output and electronically stored information, including one or more of electronically stored rules, parameters, and instructions, to determine whether or not one or more types of entities are present within an area, volume, or environment monitored by the intelligent controllers. The intelligent controllers select operational modes and modify control schedules with respect to the presence and absence of the one or more entities. The intelligent controllers employ feedback information to continuously adjust the electronically stored parameters and rules in order to minimize the number of incorrect inferences with respect to the presence or absence of the one or more entities and in order to maximize the efficiency by which various types of systems controlled by the intelligent controllers carry out selected operational modes.

Abstract: A smart-home device may include a user interface having a first operating mode and a second operating mode, and a four-channel thermopile. A processing system may be programmed to receive an indication of a user presence near the smart-home device from the thermopile, and determine a motion signature based on the responses from the thermopile. The processing system may also be programmed to process the determined motion signature to determine the presence of a condition warranting user interface entry into the first mode from the second mode, and cause the user interface to transition from the first mode to the second mode based on the determined motion signature.
