Abstract: Communication systems are described that use signal constellations, which have unequally spaced (i.e. ‘geometrically’ shaped) points. In many embodiments, the communication systems use specific geometric constellations that are capacity optimized at a specific SNR, over the Rayleigh fading channel. In addition, ranges within which the constellation points of a capacity optimized constellation can be perturbed and are still likely to achieve a given percentage of the optimal capacity increase compared to a constellation that maximizes dmin, are also described. Capacity measures that are used in the selection of the location of constellation points include, but are not limited to, parallel decode (PD) capacity and joint capacity.

Abstract: An HVAC controller includes a housing, a user interface and a controller that is operably coupled to the user interface and is configured to display a HOME screen on the user interface that provides the user with current system operating information and enabling the user to access a hierarchical menu structure for viewing and/or editing one or more settings of the HVAC controller. The hierarchical menu structure includes a plurality of menu branches each having two or more hierarchical menu levels with a leaf menu at the bottom of each branch, where for a first group of the leaf menus, the user must navigate “back” to return to the HOME screen while for a second group of the leaf menus, the user is returned to the HOME screen after the user indicates the user is done with the leaf menu, without having to wait for the timeout period.

Abstract: An HVAC controller is configured to receive signals from a plurality of sensors positioned in different spaces. The HVAC controller includes a controller that is configured to display one or more screens on a user interface that include a home screen including a selectable display element that indicates a number of the plurality of sensors that are currently being used by the controller in controlling the HVAC system. Upon selection of the selectable display element, the controller displays a sensor priority screen that includes a plurality of graphic constructs that each identify a building space and a current temperature for that building space. The controller is configured to control the HVAC system in accordance with the current temperature reported by each of the number of the plurality of sensors that are currently being used by the controller in controlling the HVAC system.

Abstract: An HVAC controller is configured to automatically change between a HEAT mode and a COOL mode in accordance with a sensed temperature in the building structure, a HEAT temperature set point and a COOL temperature set point. The user is allowed to adjust the HEAT temperature set point and the COOL temperature set point, with the HVAC controller automatically adjusting one of the set points in response to the user making a change to the other of the other of the set points that violates a minimum deadband. If the user readjusts the user-adjusted set point in a way that no longer violates the minimum deadband, the HVAC controller will adjust the other set point back towards its previous setting.
