Abstract

A computer-based apparatus provides access to complex technical information needed, for example, to maintain and repair complicated equipment, such as a motor vehicle. The apparatus includes a combined user interface and main control module to communicate with at least one remotely operated instrumentation module to control and obtain data by wireless communication. The combined user interface and main control module has an interactive display which enables the user to command the functions of the remotely deployed instrumentation module(s) and enter data through interaction with the display, as well as executes diagnostic application programs and displays information to the user. Alternatively, a separate user interface module and main control module connected by wireless communication can be provided, in which the user interface module not only commands the functions of the instrumentation module(s), but also commands remote execution of diagnostic application programs by the main control module.

Claims

1. An apparatus for analyzing an automobile, comprising:

a hands-free user interface device; and

a first measurement instrumentation device coupled to the automobile and the hands-free user interface device, the first measurement instrumentation device having a capability to receive data from the hands-free user interface device for use in analyzing the automobile.

2. The apparatus of claim 1, comprising:

a wireless transmission link coupled to the hands-free user interface device and the first measurement instrumentation device, the wireless transmission link enables wireless communication between the hands-free user interface device and the first measurement instrumentation device.

3. The apparatus of claim 1,

the hands-free user interface device including a visual display device.

4. The apparatus of claim 1,

the hands-free user interface device including a microphone.

5. The apparatus of claim 1,

the hands-free user interface device including a speaker.

6. The apparatus of claim 1, including:

a processor device for processing audible data.

7. The apparatus of claim 1,

the hands-free user interface device including a pair of glasses having a display device.

8. The apparatus of claim 7, including a microphone.

9. The apparatus of claim 7, including a speaker.

10. The apparatus of claim 1, comprising:

a second measurement instrumentation device coupled to the automobile and the hands-free user interface device, the second measurement instrumentation device having a capability to receive data from the hands-free user interface device for use in analyzing the automobile.

11. The apparatus of claim 10,

a wireless transmission link coupled to the hands-free user interface device and the first and the second measurement instrumentation devices, the wireless transmission link enables wireless communication between the hands-free user interface device and the first measurement instrumentation device and between the hands-free user interface device and the second measurement instrumentation device.

12. The apparatus of claim 1,

wherein the hands-free user interface device is an audio-activated user interface device.

13. A method for analyzing an automobile, comprising the steps of:

coupling a first measurement instrumentation device to the automobile;

linking a hands-free user interface to the first measurement instrumentation device;

using the hands-free user interface to request data from the automobile; and

transmitting the request from the hands-free user interface to the first measurement instrumentation device.

14. The method of claim 13, comprising the steps of:

providing a display device as part of the hands-free user interface;

receiving, in the hands-free user interface, the requested data from the first measurement instrumentation device; and

displaying the requested data in the display device.

15. The method of claim 13, comprising the steps of:

coupling a second measurement instrumentation device to the automobile and the hands-free user interface; and

transmitting a request for data to the second measurement instrumentation device.

16. The method of claim 13,

providing a wireless transmission link between the hands-free user interface and the first measurement instrumentation device;

and

the transmitting step further comprising the step of transmitting the request to the first measurement instrumentation device through the wireless communication link.

17. The method of claim 13,

providing a speaker device as part of the hands-free user interface;

receiving, in the hands-free user interface, the requested data from the first measurement instrumentation device; and

broadcasting the requested data through the speaker device.
