Abstract: A system includes one or more transponders, a number of sensors, a tracking sub-system, and a billing sub-system. Each transponder is located in a vehicle capable of being driven on a road having at least a first lane and a second lane in which vehicles move in a same direction. Each sensor is movably located at a point along the road to detect the transponder of each vehicle that has changed between the first and the second lanes at the point. The tracking system is communicatively coupled to the sensors to track when and at which of the points the vehicles have changed between the first and the second lanes. The billing system is to periodically bill users of the vehicles based on when and where the vehicles are driven in the second lane of the road.

Abstract: An intrusion detection system, and a related method and computer program product, for implementing intrusion detection in a remote, on-demand computing service environment in which one or more data processing hosts are made available to a remote on-demand user that does not have physical custody and control over the host(s). Intrusion detection entails monitoring resources defined by the on-demand user (or a third party security provider) for intrusion events that are also defined by the on-demand user (or security provider), and implementing responses according to event-action rules that are further defined by the on-demand user (or security provider). An intrusion detection system agent is associated with each of the data processing hosts, and is adapted to monitor the intrusion events and report intrusion activity. If there are plural intrusion detection system agents, they can be individually programmed to monitor and report on agent-specific sets of the intrusion events.
