An apparatus and method for use at a motor vehicle emission test station, providing wireless communication between a computer and a technician. The computer includes a sound card and voice recognition software, and is housed in a console, having test equipment, video and audio transmitters, and an audio receiver. The technician wears a portable user interface, including a communications pack with a video receiver, an audio receiver, an audio transmitter, and a battery pack. The interface also includes a special helmet, equipped with a video display, a microphone, and headphones. The wireless communications link established by these transmitters, receivers, and interface components enables the technician to carry out testing and inspection procedures on a motor vehicle in a location remote from the computer. Visually and aurally, the computer provides testing and inspection information and procedures to the technician, and the technician orally enters vehicle identification and license plate information, issues commands, and enters test and inspection results in communication with the computer.

The combination of ambient air, exhaust and premeasured calibration gases is used according to this invention in the analysis of either low or high pollutant concentration gases measured by a single range analyzer. By using ambient air as a diluent and employing its concentration values to generate the Reference Dilution Ratio, DR. sub. ref, iterative calculations are made to find the Raw Sample Concentration value, C. sub. raw. The gas diluting/mixing system includes pressure balanced infeed plumbing legs. Each of the legs feeds to respective flow restrictors and a common, downstream mixing "T" fitting. One leg is interconnected to the high concentration emission gas output from the sampling system and high concentration calibration gas. The other leg is interconnected to the diluent gas source, ambient air.

A plurality of vehicle service stations are located in a geographical area, each station includes one or more service bays in which the vehicle is serviced, each bay has an associated lane in which one or more vehicles wait their turn to be serviced in the bay, each lane has one or more sensors for sensing the presence of vehicles in the lane. Each station has a computer which is responsive to the lane sensors for computing the waiting time at the station for a vehicle, the waiting time for each station is displayed on a visual display at the station, the waiting time from each station is also communicated to a host computer centrally located with the geographical region. The host computer has an associated phone messaging system which is responsive to phone calls made from phones in the geographical area, the host computer calculates a recommended station to proceed to and provides a digitized voice of this recommendation through the phone messaging system to a potential customer calling the messaging system over the phone.

A method and apparatus for measuring leakage of a vehicle fuel system includes providing an apparatus having a gas source, a pressure meter and a reference orifice and connecting the apparatus to the fuel system. The fuel system is pressurized with the source. A first set of pressure measurements is obtained using the pressure meter with gas escaping the fuel system through leakage of the fuel system. A second set of pressure measurements is obtained with gas escaping the fuel system through leakage of the fuel system and through the reference orifice. An effect of fuel vapor pressure created by fuel in the vehicle fuel system may be measured. A leakage parameter of the fuel system may be calculated from the first and second sets of pressure measurements including compensating for the effect of fuel vapor pressure.

A vehicle communication system and method of communicating data from a vehicle, such as for inspecting or diagnosing a vehicle, includes providing a plurality of vehicle units each including a vehicle wireless communication transceiver and a memory. Data, such as vehicle data from a vehicle diagnostic system, is stored in the memory. A communication system is provided for two-way wireless communication with the vehicle units. The communication system is made up of one or more mobile wireless communication transceivers. Vehicle data is communicated from the memory to one of the mobile wireless communication transceivers that is in the vicinity of that vehicle unit. The transporting of the mobile wireless communication transceiver increases interaction between the communication system and the vehicle units.

A computer system, including a relational database, especially for use by an inspector at a Motor Vehicle Inspection facility, for capturing, storing, retrieving, and displaying visual images disclosing the identification and location of vehicle Emission Control System (ECS) components. A method for systematically creating, updating, and using the relational database is also disclosed. The database is composed of three data libraries, one for ECS Vehicle Underhood Images, one for ECS Component Overlays, and another for ECS Component Lists. These libraries include visual and factual information regarding the identity and location of ECS required components for a plurality of vehicles. The libraries are maintained and used in the database in such a way as to minimize storage space and maximize the speed of data access and display.

A vehicle testing system and method includes a vehicle testing system that is operatively connected with a vehicle computer whereby the system is able to evaluate signals within the vehicle computer. The system includes a tamper testing sequence for detecting vehicle tampering comprising applying a test action to the vehicle intended to generate a signal in the vehicle computer responsive to the test action, monitoring the signal of the vehicle computer associated with the test action, and determining whether the signal meets an expected response. A determination that the signal of the vehicle computer associated with the test action does not meet the expected response indicates that tampering has occurred.
