Abstract: A service unit for providing a convenience service to a cab of a tractor trailer includes a supply panel which is operable to attach to a cab of a tractor trailer. The supply panel provides conditioned air to the cab. A vibration detection unit is configured to interact with the supply panel and detect an idling engine by detecting a vibration with a vibration detector, transmitting the vibration as vibration signals to a controller, performing a signal analysis on the vibration signals to identify an engine idle signature, and storing a duration of the engine idle signature.

Abstract: An apparatus for providing convenience services to a stationary vehicle independent of the vehicle's electrical system. At least one conduit is attached to a housing for transferring the services to a supply panel. The supply panel includes a face on which the various controls and connectors associated with the supplied convenience services, such as heating, cooling, electrical power, compressed air, computer network communications, telephone, video, and television, are disposed. The supply panel is dimensioned to interface with the stationary vehicle through an opening in the vehicle, such as a window or service door, and includes means for providing a substantially airtight seal for climate control.
