Abstract:
1. A mobile data system having automated shutdown, wherein said mobile data system is mounted in a motor vehicle having a vehicle motor and a vehicle electrical power source for providing variable voltage electrical power to said motor vehicle and said mobile data system, said mobile data system comprising: a system computer having means for informational data retrieval in response to user input queries and means for creating a system shutdown command in response to parameter comparison data; a system interface device electrically connected with said vehicle electrical power source to receive variable voltage electrical power directly from said vehicle electrical power source; a computer power supply positioned in series between said system computer and said system interface device and electrically connected with said system interface device and said system computer to receive said variable voltage electrical power from said system interface device, convert said variable voltage electrical power directly to voltage regulated electrical power, and transmit said voltage regulated electrical power directly to said system computer for informational data retrieval operation thereof; means for creating said parameter comparison data, wherein said parameter comparison data is a comparison of actual parameter values of an established operating parameter with a threshold parameter value; and means for interrupting transmission of said voltage regulated electrical power from said computer power supply to said system computer in response to said system shutdown command.
