| 20120126019 | THERMOSTAT BATTERY RECHARGING DURING HVAC FUNCTION ACTIVE AND INACTIVE STATES - A thermostat and related methods are described for controlling one or more functions, such as heating and cooling in an HVAC. According to some embodiments the thermostat includes a rechargeable battery; charging circuitry adapted and arranged to recharge the battery; and control circuitry adapted and arranged to control the one or more HVAC functions using power from the rechargeable battery. According to some embodiments, the thermostat also includes power harvesting circuitry adapted and arranged to harvest power from the HVAC system in cases where no common wire is available to the thermostat, and to supply power to the charging circuit for recharging the battery. | 05-24-2012 |
| 20120126021 | THERMOSTAT CIRCUITRY FOR CONNECTION TO HVAC SYSTEMS - A thermostat and related methods is provided for controlling an HVAC system having one or two separate transformers for supplying power to the HVAC system. The thermostat includes isolation circuitry housed within the thermostat to safely connect to the HVAC control wires and power wire(s) whether the HVAC system has one or two separate transformers without the use of removable jumpers or manual rewiring. The thermostat can include a processor that sends DC signals for turning on and turning off each of the HVAC functions, and an isolator adapted to electrically isolate the processor from the control wires and power wire(s). The isolator can include a transformer, such as a low cost Ethernet transformer. The circuitry can include one or more field effect transistors adapted and arranged so as to open or close an electrical connections between the control and power wires, thereby turning on or off the associated HVAC function. According to some embodiments, the Rc and Rh terminals are permanently connected using a fuse. | 05-24-2012 |

| 20110161469 | METHOD FOR BUILDING SPONTANEOUS VIRTUAL COMMUNITIES BASED ON COMMON INTERESTS USING INTEREST BANDS - The present invention refers to a method for establishing communication between equipments within groups and/or communities, which are formed according to the interest of each user. The equipments are programmable, allowing inserting predicates based on the interests of the user, creating interest bands. The communication equipment syntonizes the interests of an user with the interests of a group. The interest bands are formed with predicates which contain both anonymous and identified information; in this case, the user allows such information to be shared with all or with groups of same interest bands. The method is preferably distributed and communication is spontaneous and volatile. | 06-30-2011 |

| 20090149206 | Method for Building Spontaneous Virtual Communities Based on Common Interests Using Wireless Equipments - The present invention refers to a method for establishing a communication network that connects a group or community of users using wireless equipments according to their defined interests. These equipments are preferentially portable, low cost, and user-friendly, where each equipment must be configurable using its user's profile, which contains a small amount of the user's personal data, namely the miniprofile. The method uses a collection of such miniprofiles to transparently set a communication network among the associate users to establish a virtual community. In addition, each profile will contain further information on user's interests, which the method will propagate across the communication network to the established virtual community in a way that their members will be able to form groups based on common interests while allowing for interaction among their members. The user profile can be set identifiable or anonymous, may or not be shareable in relation to the other members of a group. The method is distributed, and supports spontaneous and volatile communication networks, preferentially. | 06-11-2009 |
