Abstract

A distributed computer-implemented diagnostic system for determining a diagnostic state of a component. The component exhibits measurable characteristics. The system includes a database that stores reference component characteristic data. A computer server is connected to the database, and a computer client is connected to the computer server via a network. The client computer provides data requests to the server computer in order to retrieve the component characteristic data from the database. A portable computer is connected to the computer client in order to have data access to the retrieved component characteristic data and to provide the component characteristic data for performing diagnosis. The diagnostic state of the component is determined based upon the retrieved component characteristic data as provided by the portable computer and upon at least one of the measurable characteristics of the component.

Claims

1. A distributed computer-implemented diagnostic system for determining a diagnostic state of a component, said component exhibiting measurable characteristics, comprising:

a database that stores reference component characteristic data;

a computer server connected to the database;

a computer client connected to the computer server via a network, said client computer providing data requests to the server computer in order to retrieve the component characteristic data from the database;

a portable computer connected to the computer client in order to have data access to the retrieved component characteristic data and to provide the component characteristic data for performing diagnosis,

wherein the diagnostic state of the component is based upon the retrieved component characteristic data as provided by the portable computer and upon at least one of the measurable characteristics of the component.

2. The system of claim 1 wherein the electrical component is a component from a vehicle.

3. The system of claim 1 wherein the portable computer is connected to an ohmmeter and voltmeter capable of running vehicle diagnostics.

4. The system of claim 1 wherein the database includes a relational database system.

5. The system of claim 1 wherein the portable computer includes communication to a global network.

6. The system of claim 1 wherein the portable computer is a visual and audio unit.

7. The system of claim 1 wherein the portable computer is remote with respect to the computer client.

8. The system of claim 7 wherein the portable computer includes a wireless communication unit in order to communicate with the computer client.

9. The system of claim 8 wherein the wireless communication unit includes a radio frequency (rf) communication unit in order to provide communication between the portable computer and the computer client.

10. A distributed computer-implemented vehicle diagnostic system for evaluating a vehicle, comprising:

a database that stores reference vehicle electrical data;

a computer server connected to the database;

a computer client connected to the computer server via a network, said client computer providing data requests to the server computer in order to retrieve the vehicle electrical data from the database;

a portable computer connected to the computer client in order to have data access to the retrieved vehicle electrical data,

said portable computer indicating diagnostic state of the vehicle based upon the retrieved vehicle electrical data.

11. A distributed computer-implemented diagnostic system for determining a diagnostic state of a component, said component exhibiting measurable characteristics, comprising:

a database that stores reference component characteristic data;

a computer server connected to the database;

a portable computer connected to the computer server via a network, said portable computer providing data requests to the server computer in order to retrieve the component characteristic data from the database;

wherein the diagnostic state of the component is based upon the retrieved component characteristic data as provided by the portable computer and upon at least one of the measurable characteristics of the component.

12. A distributed computer-implemented diagnostic system for allowing a technician to determine the diagnostic state of a component, wherein said component exhibits a measurable characteristic, comprising:
