        Exact oil level (110)
        Exact number of gallons (115)
        Octane rate of gasoline (125)
        Exact emission rate (120)
        Interface Port (130)
    
    


In the preferred embodiment of the present invention, device (10) is dimensioned to be mounted inside the gas lid of the vehicle. In other embodiments, device (10) can be mounted within a vehicle's dashboard. The entire unit is lightweight and weighs between 5–8 ounces.
This embodiment includes an input device for entering data into the system through port (130). The input device can be a touch screen, a voice activated mechanism, and a keyboard input device or another such compatible input device. The display device (10) can be an LCD, an OLED or another such compatible flat or flexible display device.
As shown in FIG. 1A, the system can include a first hand-held device (320) for the consumer or an automotive repair shop. The first hand-held output device (320) would have a display which indicates the status of several of the sensor leads as described below. For example, if the spark plugs need to be replaced then the device would indicate it through indicator lights (325). In operation, the first hand-held output device (320) would be operationally connected to input port (130) via a hard-wire or a wireless connection.
As shown in FIG. 1A, the system can include a second hand-held device (330) for the law enforcement official. The second hand-held output device (330) would have a display (335) which indicates the status of the emission of the vehicle. For example, the display (335) would indicate pass or fail. Display (335) can be implemented in a color bar or grid. Green can mean pass, yellow can be caution, and red can means fail. In operation, the second hand-held output device (330) would be operationally connected to input port (130) via a hard-wire or a wireless connection.
Referring to FIG. 2, there is shown an operational block diagram of device (10). The system includes micro-processor (200) connected to a plurality of sensor leads (205). An analog to digital converter (A/D) can be utilized to read analog signals from sensor leads that emit analog signals. The A/D would convert the signals from the sensor leads into digital streams that the microprocessor can read.
The sensor leads can be R/F/A Gallium Sensors or another such compatible sensor lead. In this embodiment, the sensor leads (205) receive information from various vehicle fluid and mechanical components including but not limited to:
















Oil Reservoir
Points



Muffler Emission
Transmission



Gas Tank
Cooling System



Fuel Injectors
Radiator



Computer Interface
Catalytic Converter



Battery
Brake Fluid



Alternator
Reservoir



Spark Plugs
Belt Tension







Timing









The software program includes vehicle classes (210) which define the data to be stored and the operations to be performed by the software modules that monitor the vehicle fluid and mechanical components. A vehicle object will have to be defined for each type of vehicle to be monitored. The data stored in the objects includes representation of the data received from the sensor leads defined above. The information received includes fuel (225), quality (220) and quantity (215) related sensor data. The sensor leads can report two states (active and dynamic). An active state attributes involve the recording of exposure to negative environments such as wet, dry, heat or vibrations. The dynamic state attributes involve the recording of enhanced performance data.
Additionally, the processor can be interfaced with the existing computer (300) of the vehicle and where applicable provide a check and balance against the data being analyzed by the system of the present invention. The vehicle computer can also be attached to several leads (305) which provide the data which vehicle computer (300).
User interface software (255) is required to allow the user to setup the device to monitor the vehicle and to the control the monitoring process. In some embodiments, the user interface can be adapted to execute through a separate input device connected to port (130). In other embodiments, user interface software (255) can be setup to execute through a touch screen input device which is operationally incorporated into display (240).
In use, the user via an operational setup screen (235) through the User Interface Software (255) defines the control settings to monitor the air quality of the vehicle through the sensor leads, initiating the system to monitor the vehicle. The setup screen (235) can be a touch screen input device. The processor (200) can periodically poll the sensor leads for information and store the data in the vehicle objects (210). Significant event information can be sent to the processor (200) from the sensor leads (205). Additionally, the dynamic state attributes can allow users from the touch tone to initiate the display of real time data. After information has been transmitted to the processor, the received sensor information is stored in memory for display onto the dashboard (246) or on the gas lid (245).
