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.

1. An intelligent controller comprising: a processor;a memory that stores a control schedule and an indication of a presence state,one or more sensors; andinstructions stored within the memory that, when executed by the processor, controls the intelligent controller to record output from the one or more sensors in memory, andat intervals, determine a probability of presence of one or more entities within a region of a controlled environment using the recorded sensor output in memory,update the indication of the presence state, andupon a change of the indication of the presence state, accordingly adjust the control schedule;wherein determining a probability of presence of one or more entities within a region further includes determining, for one or more regions and volumes within the controlled environment, one or more of one or more presence-probability maps, andone or more presence-probability scalar values; andwherein the intelligent controller determines the probability of presence of one or more entities within one or more regions and volumes within the controlled environment by for each of the one or more regions and volumes, determining a cumulative presence-probability scalar or cumulative presence-probability-map values from a presence-probability scalar or from presence-probability-map values determined from output of each of the one or more sensors, andapplying rules to the cumulative presence-probability scalar or cumulative presence-probability-map values in order to adjust the cumulative presence-probability scalar or cumulative presence-probability-map values for one or more additional considerations based on the additional electronically accessible information. 2. An intelligent controller comprising: a processor;a memory that stores a control schedule and an indication of a presence state,one or more sensors; andinstructions stored within the memory that, when executed by the processor, controls the intelligent controller to record output from the one or more sensors in memory, andat intervals, determine a probability of presence of one or more entities within a region of a controlled environment using the recorded sensor output in memory,update the indication of the presence state, andupon a change of the indication of the presence state, accordingly adjust the control schedule;wherein the intelligent controller updates the indication of the presence state by when a probability of presence for a region rises above a first threshold, setting the indication of the presence state for the region to indicate the presence of an entity in the region, andwhen a probability of presence for a region falls below a second threshold, setting the indication of the presence state for the region to indicate the absence of an entity in the region. 3. An intelligent thermostat comprising: a processor;a memory that stores a control schedule and an indication of a presence state,one or more sensors; andinstructions stored within the memory that, when executed by the processor, controls the intelligent controller to record output from the one or more sensors in memory, andat intervals, determine a probability of presence of one or more people within a region of a controlled environment using the recorded sensor output in memory,update the indication of the presence state, andupon a change of the indication of the presence state, accordingly adjust the control schedule;wherein the indication of a presence state indicates one of a home state,an away-normal state,an away-vacation state, anda sleep state; andwherein the intelligent thermostat determines the probability of presence of one or more people within one or more regions and volumes within the controlled environment by for each of the one or more regions and volumes, determining a cumulative presence-probability value, andapplying rules to the cumulative presence-probability value in order to adjust the cumulative presence-probability value for one or more additional considerations based on the additional electronically accessible information. 4. The intelligent thermostat of claim 3 wherein the intelligent thermostat updates the indication of the presence state by: when a probability of presence for a region rises above a first threshold, setting the indication of the presence state for the region to indicate the presence of an entity in the region; andwhen a probability of presence for a region falls below a second threshold, setting the indication of the presence state for the region to indicate the absence of an entity in the region.
