|20120248208||AUXILLARY SWITCH FOR MULTIPLEXED CONTROL AND GROUND SIGNAL FROM A THERMOSTAT - An auxiliary switch is provided that allows a thermostat to use full wave rectification for power while still communicating control information to the auxiliary switch over a multiplexed ground-control line to control associated equipment.||10-04-2012|
|20120061480||PORTABLE INFORMATION DISPLAY DOCKABLE TO A BASE THERMOSTAT - A thermostat system is provided that comprises a base thermostat for providing basic thermostat control and a portable information display (PID) unit, or dockable display, that provides an improved user interface. The PID unit can be docked to the base thermostat by being releasably mounted on top of a front portion of the base thermostat. The base thermostat provides control of an environmental control system, allowing the regulation of the temperature in a building. The PID unit may be used when it is mounted to the base thermostat or un-mounted from the base thermostat. The PID unit provides an improved user interface and experience over the base thermostat.||03-15-2012|
|20090234505||GROUND WIRE ADAPTOR - A ground wire adaptor for operatively connecting a low-voltage control unit (e.g. a thermostat) requiring a three-wire connection to a three-wire system-under-control (e.g. a HVAC system) using a two-wire conductor. A ground terminal and an output control signal of the control unit are interconnected such that the output control signal, in the form of a half-wave rectified signal, is superimposed on the ground. The ground wire adaptor detects the half-wave rectified signal superimposed on the ground connection and generates a control output signal to be provided to the system-under-control responsive to the presence of the half-wave rectified signal (i.e. the control signal from the control unit). In another aspect of the invention the ground wire adaptor can be used to connect an ‘N’ function control unit to an ‘N’ function system-under-control using a two-wire conductor.||09-17-2009|
|20080218245||SOLID-STATE SWITCH - A solid state switch that employs a controller driven input and MOSFET power switching devices is disclosed. The controller can test for a short-circuit on the load side of the MOSFET power switching devices before putting the switch in a sustained conductive state.||09-11-2008|
