Abstract: A mobile data system having automated shutdown is mounted in a motor vehicle having a vehicle motor and a vehicle electrical power source. The vehicle electrical power source provides variable voltage electrical power to the motor vehicle and to the mobile data system. The mobile data system includes a system computer for informational data retrieval in response to user input queries, a system interface device, and a computer power supply. The computer power supply is electrically coupled with the vehicle electrical power source through the system interface device to convert the variable voltage electrical power to voltage regulated electrical power for operation of the system computer. The system interface device creates parameter comparison data, in response to which the system computer creates a system shutdown command.

Abstract: A DIP or surface mount type switch (10) contains a built-in electronic system for direct interfacing to an electronic circuit. The DIP switch and the built-in electronic system consisting of bias resistors (22), active buffers (14), and decoding circuitry (18), are combined as a single package. These components will be mounted and interconnected to a substrate PCB (26), or chip carrier package (31), or as an integral unit within the switch housing (12). This DIP switch also includes socket pins or mounting leads (30) to connect the assembly to a system circuit board.
