Abstract: A system, method, and computer program product for monitoring and aggregating user activities across heterogeneous systems. The system, method, and computer program product retrieve information about the heterogeneous systems and rules, monitor user activities in the heterogeneous systems according to the rules, reconcile the user activities by providing supplemental information, aggregate the monitored activities, and report the aggregated user activities to authorized users.

Abstract: A switch connected to a power source is closed automatically in response to a vehicle being conditioned for travel and is opened in response to the vehicle being stopped. First and second apparatuses deliver first and second electrical signals, respectively, to a switching device in response to the switch being closed. The switching device is rendered conductive for connecting the power source to an alarm for energizing the alarm when either one or both of the first and second signals is delivered thereto. The switching device is rendered nonconductive for deenergizing the alarm in response to neither of the signals being present. A timer stops delivery of the first signal to the switching device only after the first signal has been delivered to the switching device for a predetermined period of time. A manual override is provided for manually selectively stopping delivery of the second signal to the switching device.

Abstract: A start timer circuit for a diesel engine is responsive to the operator actuated start switch. The timer circuit energizes the engine start motor circuit for at least a minimum time, sufficient to avoid sustained firing of the engine at a low speed. Safety circuits prevent false energization of the start motor circuit in the event of malfunction or failure of various circuit components.
