Abstract: Improvements in a thermostat for HVAC control and an irrigation controller for sprinkler control are constructed each with a Base Unit and a removable User Interface Unit. The dual-function Base Unit is configurable for use as either a thermostat or an irrigation controller. The Base Unit has a connector for connection to a separate User Interface (UI) Unit. The separate UI Unit has a display, controls, and I/O Connector for connection to a Base Unit or an external computer. The UI Unit adaptively operates as a thermostat interface or irrigation interface, as is appropriate for the configuration of a connected Base Unit. The UI Unit can be connected via its I/O Connector to a PC, tablet PC, or smart phone for configuration of operational control settings using application software. The configuration settings are transferred from a UI Unit to a Base Unit upon connection via the I/O Connector.

Abstract: Improvements in a smoke alarm are presented. The multifunction smoke alarm unit includes separate sensors within a single enclosure for detecting smoke and occupancy, sounding a distinctive audible alarm when combustion is detected or the presence of a person within the area of the sensor. The multifunction smoke alarm can replace an existing single function smoke alarm. Multiple multifunction smoke alarms are networkable together for various purposes. Additional features include intruder alarm, visitor annunciator, integrated illumination source, external lighting control, HVAC system control, ceiling fan control, ventilation control, and/or fire safety system control. The proposed multifunction smoke alarm provides much-needed improvements for security, energy saving, safety, and user convenience without the need for completely separate systems for each purpose.
