Abstract: An emergency egress lighting system for a vehicle having multiple egress portals, including first sensors and second sensors that sense information as to vehicle orientation in pitch and roll. A plurality of indicators is changeable between a positive indication and a negative indication locatable inside the vehicle near one of the multiple egress portals. The plurality of indicators display a positive indication and a negative indication at each of the multiple egress portals based on the vehicle orientation in pitch and roll such that a first portion of the plurality of indicators displays the positive indication proximate least one first selected egress portal that is less or least likely to be blocked to prevent egress while a second portion of the of the plurality of indicators display the negative indication proximate at least one second selected egress portals that is more or most likely to be blocked to prevent egress.

Abstract: An Outrigger Obstruction Detection System for an Aerial Fire Truck that will warn the driver of an impending obstruction to an outrigger prior to full extension of the outrigger. The system comprises ultrasonic sensors located at or near each outrigger assembly on the aerial fire truck, which can be programmed to detect an object within the travel range of the outrigger. In addition, a control/indicator panel is mounted in the cab of the aerial fire truck. The control/indicator panel is positioned in the cab to allow the driver physical and visual access. The control/indicator panel contains the power switch, diagram of the truck and indicator lights used to warn the driver of an obstruction. The sensors provide an electrical signal to a control/indicator panel located in the cab of the aerial fire truck to alert the driver if an object is detected. This alert allows the driver to reposition the truck to clear the obstruction, which in turn reduces the time to react to the emergency.
