A home automation system and method for automatic control of controlled devices throughout a home. A unique architecture of occupancy sensors includes entry/exit sensors for detecting movement through doorways that separate rooms in the home, room motion sensors for detecting room occupancy, spot sensors to detect occupancy of specific locations within the rooms, and house status sensors to detect the status of certain parameters of the home. A central controller communicates with the sensors and controlled objects over a communications network, where the sensors and controlled objects can be added to the system in a ‘plug and play’ manner. The central controller controls the controlled objects in response to the entry/exit sensors, room motion sensors, spot sensors and the house status sensors. This control is accomplished by assigning each room to one of a plurality of room occupancy states, and to one of a plurality of room modes for creating desired room atmospheres using the controlled objects, which both dictate how the controlled objects are controlled by the central controller. The room modes travel from room to room as the occupant moves throughout the home, and multiple occupants can be using different room modes as they move about the home. The controlled objects also have controlled object states, which are used by the central controller to control the controlled objects.

The improved building automation system of the present invention is modular in the extreme. This diminishes the amount of custom programming required in order to affect control of a particular building. It allows for a relatively open architecture which can accommodate a variety of unique control applications which are scripted for a particular building. By modularizing many of the common processes utilized in the automation system, the custom programming required to control any particular building is minimized. This modularity in design allows for uniform and coordinated control over a plurality of automation subsystems which may be incompatible with one another at the device or machine level, but which can be controlled utilizing a relatively small and uniform set of "interprocess control commands" which define an interprocess control protocol which is utilized in relatively high level scripts and control applications which may be written for a particular building.

The present invention is related to the field of heating, ventilation and air conditioning (HVAC). More particularly, the present invention is related to methods and systems for controlled heating and cooling in order to reduce costs and the carbon footprint of said heating and cooling by optimizing the use of fresh air ventilation. The present invention is directed to mathematical algorithms incorporated into a controller and a method of determining control signals that are dependent on said mathematical algorithms and user programming that integrates information from multiple sensors, thermostats as well as weather information. Used in any home or building, the controller controls heating, cooling and ventilation systems in order to reduce costs and the carbon footprint of said heating and cooling by optimizing the use of fresh air ventilation. The controller works with typical HVAC systems generally in buildings and homes. The Smart-Stat algorithms are programmed into the controller and enable the controller to identify user-determined set-points alongside data from one or multiple internal temperature sensors. The user-determined set-points are also linked to time of day and day of week in a manner typical for typical thermostat devices available today. In such typical thermostat devices the controller will call for cooling or heating depending on the set points and conditions determined by the sensors in the building. The present invention is capable of interrupting the call for cooling or heating depending on whether the mathematical algorithms identify suitable outside weather conditions that permit the use of outside air cooling or outside air heating. Thus the call for heating or cooling can be redirected to call for ventilation instead of heating or cooling.

In a coupled control mode, the surgeon directly controls movement of an associated slave manipulator with an input device while indirectly controlling movement of one or more non-associated slave manipulators, in response to commanded motion of the directly controlled slave manipulator, to achieve a secondary objective. By automatically performing secondary tasks through coupled control modes, the system's usability is enhanced by reducing the surgeon's need to switch to another direct mode to manually achieve the desired secondary objective. Thus, coupled control modes allow the surgeon to better focus on performing medical procedures and to pay less attention to managing the system.
