Abstract: Dynamic television audience measurement systems (AMS) and methods are disclosed. The system comprises a central level AMS sub-system, a local node level AMS sub-system, a plurality of client level AMS sub-systems, and a plurality of display devices, each monitored by a client level AMS sub-system. The central level AMS sub-system receives panel definitions from panel requestors and transmits the panel definitions to and receives a merged viewership report from the local node level AMS sub-system. The local node level AMS sub-system receives panel definitions from and transmits the merged viewership report to the central level AMS sub-system, transmits the panel definitions to and receives viewership reports from the plurality of client level AMS sub-systems, and merges the viewership reports into the merged viewership report. Each client level AMS sub-systems receives panel definitions from and transmits the viewership report to the local node level AMS sub-system and compiles the viewership report.

Abstract: A vehicle-mounted image record system for ensuring safe driving of a vehicle by recording images of a portion of the vehicle and a surface of a road in the vicinity of the vehicle so as to monitor the driving habits of a driver. The system includes one or more cameras mounted at suitable positions on the vehicle and a recording device for recording the images captured by the cameras. The captured and recorded images include a portion of the vehicle and part of the surface of the road on which the vehicle is driving so as to serve as proof of safe driving in the event of an accident. The system also includes a display for displaying the captured images so that the driver of the car can see objects forward or reverse of the vehicle.
