Vehicle mounted ADA compliant device

Problem Description

To meet ADA compliance, municipalities that operate public transportation must provide accommodations for the visual and hearing impaired. Additionally, since the devices are to maintained by existing personnel, they must conform to existing connection and mounting specifications.

Product Description

The goal was to design a product that could meet the above requirements and provide additional functionality at no additional cost. Some of the features are as follows:

• Extruded aluminum design provides a mechanism to dissipate heat without fans
• Dual Processor architecture allows a standard embedded operating system to be used to manage the "PC-like" devices while unique vehicle requirements use a processor better suited for that interface
• 40 Watt stereo amplifier provides the required output to meet ADA requirements for the visually impaired
• Integrated GPS with proprietary code allows the vehicle to be tracked when GPS signals are lost or compromised
• A wireless communications interface coupled with full integration on the vehicle electrical "bus" allows automatic reporting of sensor status when the vehicle returns to the maintenance facility
• Automatic tracking provides real-time vehicle location to central operations
• Emergency management system provides security status to central operations
• Manufacturing processes used provide a "sealed" environment making the unit impervious to moisture or other environmental contaminants
