Abstract: Some embodiments include a navigational process for alerting a user of a portable navigational device of an upcoming point of interest. The navigational process may be implemented as a navigational software application that runs on the portable navigational device. In some embodiments, a wide-area global positioning system (GPS) provides navigational route information and points of interest information to the portable navigational device after the navigational process requests the navigational route information. In some embodiments, the wide-area GPS system retrieves the navigational route information from a map service. In some embodiments, the wide-area GPS system retrieves the points of interest information from a points of interest (POI) service.

Abstract: An indoor climate control system is configured to adjust a first temperature of a first room within a structure. The indoor climate control system has a receiver mechanically coupled to an HVAC unit configured to turn the HVAC unit on and off. A portable wireless thermostat communicatively coupled to the receiver. The portable wireless thermostat transmits a desired climate information to the receiver which then engages the HVAC unit to adjust the first temperature of the first room.
