Abstract: A survey message is received at a server from a host of a broadcast station currently broadcasting a program over a broadcast network, which is one of a TV program and radio program, where the survey message is to survey an audience of the program concerning content of the program. The survey message is then transmitted to communication devices of a plurality of users who have registered with the server to participate in the program over a data network. Response messages are received from at least some of the registered users in response to the survey message, each response message including geographic information collected from the communication devices of the users. An analysis is performed on the response messages to generate a statistical result representing percentages of answers selected by the users in view of the geographic and/or demographic information of the users.

Abstract: A thermostat controlled vent system for automatically controlling airflow through a HVAC vent. The thermostat controlled vent system includes a vent unit having a drive motor that operates the baffle member within the vent unit. A central control unit is preferably in communication with one or more vent units for controlling the position of the respective baffle member within. In an alternative embodiment, the vent unit may have a thermostat unit positioned within the frame structure of the vent unit for controlling the drive motor. A rechargeable battery unit is positioned within the vent unit that is charged by a power source. One or more solar cells may be electrically connected to the battery unit for charging the battery unit.
