Abstract

An inspection apparatus adapted for use in motor vehicle maintenance and repair is disclosed. A sensor, such as a video camera, is coupled by an elongated, flexible shaft to a self-contained, handheld power source. A source of illumination is mounted near the sensor and directs light onto an object that is viewed by the sensor. Input power to the sensor and the illumination source, and an output signal from the sensor, are coupled through the shaft, which will maintain any desired flexed position. Optionally, one or more microphones are mounted near the sensor to receive sounds produced by the object. Connectors extend from a housing of the power source so that the sensor output signal and an output from the microphones may be coupled to an external device. A removable clamp may be affixed to the apparatus so that the apparatus can be temporarily attached to a motor vehicle. As a result, a technician may easily visualize parts of the motor vehicle safely, clearly, and without disassembling the parts.

Claims

1. Inspection apparatus, comprising:

a sensor of electromagnetic radiation;

a radiation source mounted near the sensor that directs radiation toward an object that is sensed by the sensor; and

a flexible, elongated shaft having a distal end coupled to the sensor and a proximal end coupled to a handheld housing, and which can maintain a flexed position;

wherein the distal end of the flexible shaft is adapted to attach to a bore scope.

2. Inspection apparatus as recited in claim 1, wherein the sensor comprises a miniature video camera and the radiation source comprises a plurality of light-emitting diodes mounted about a perimeter of the camera to illuminate the object.

3. Inspection apparatus as recited in claim 1, wherein the shaft comprises a material that withstands an ambient temperature of an engine compartment of a motor vehicle.

4. Inspection apparatus as recited in claim 1, further comprising an audio transducer mounted near the sensor that receives sounds produced by the object and that is coupled through the shaft to an audio output connector proximate to the housing.

5. Inspection apparatus as recited in claim 4, wherein the audio transducer comprises one or more microphones.

6. Inspection apparatus as recited in claim 4, wherein the audio transducer comprises one or more microphones mounted in a sensor housing at the distal end of the shaft.

7. Inspection apparatus as recited in claim 6, further comprising a sensor connector in the housing and coupled to the sensor to communicate a first signal representing sensed radiation to one or more external devices, and an audio output connector in the housing and coupled to the microphones to communicate a second signal representing audio sensed therefrom to the external devices.

8. Inspection apparatus as recited in claim 6, wherein the sensor and the radiation source are mounted in the sensor housing.

9. Inspection apparatus as recited in claim 6, wherein the radiation source comprises one or more light-emitting diodes mounted around a perimeter of the sensor.

10. Inspection apparatus as recited in claim 1, further comprising a clamp that is removably mounted to the housing.

11. Inspection apparatus as recited in claim 1, further comprising a clamp having a mount that is flexibly coupled to the clamp and that is removably mounted to the housing.

21. The inspection apparatus of claim 1 further comprising a bore scope attached to the distal end of the flexible shaft.

22. The inspection apparatus of claim 1, wherein the distal end of the flexible shaft includes threads for engaging with a bore scope.

12. A motor vehicle inspection apparatus, comprising:

a video camera;

a light source mounted near the video camera and that directs light toward a part of a motor vehicle that is viewed by the video camera; and

an elongated, flexible shaft having a distal end coupled to the video camera and a proximal end coupled to a handheld housing, and which can maintain a flexed position;

wherein the distal end of the flexible shaft is adapted to attach to a bore scope.

13. A motor vehicle inspection apparatus as recited in claim 12, further comprising a clamp that is removably mounted to the housing.

14. A motor vehicle inspection apparatus as recited in claim 12, further comprising a clamp having a mount that is flexibly coupled to the clamp and that is removably mounted to the housing.

15. A motor vehicle inspection apparatus as recited in claim 12, wherein the light source comprises a plurality of light-emitting diodes mounted about a perimeter of the camera to illuminate objects viewed by the camera.

16. A motor vehicle inspection apparatus as recited in claim 12, wherein the shaft comprises a material that withstands an ambient temperature of a motor vehicle engine compartment.

17. A motor vehicle inspection apparatus as recited in claim 12, further comprising an audio transducer mounted near the sensor and coupled through the shaft to an audio output connector proximate to the housing.

18. A motor vehicle inspection apparatus as recited in claim 17, wherein the audio transducer comprises one or more microphones.

19. A motor vehicle inspection apparatus as recited in claim 12, further comprising a sensor connector in the housing and coupled to the sensor to communicate a first signal representing sensed radiation to one or more external devices, and an audio output connector in the housing and coupled to the microphones to communicate a second signal representing audio sensed therefrom to the external devices.

23. The motor vehicle inspection apparatus of claim 12 further comprising a bore scope attached to the distal end of the flexible shaft.

24. The motor vehicle inspection apparatus of claim 12, wherein the distal end of the flexible shaft includes threads for engaging with a bore scope.

20. A motor vehicle inspection apparatus, comprising:

a video camera that may view a part of a motor vehicle;

a light source mounted near the video camera and that directs light toward a part of a motor vehicle that is viewed by the video camera;

an elongated, flexible shaft having a distal end coupled to the video camera and a proximal end coupled to a handheld housing, and which can maintain a flexed position;

a self-contained power source in the housing for powering the video camera and the light source;

an audio transducer mounted near the video camera and coupled through the shaft to an audio output connector; and

a clamp that is removably mounted to the housing and that may grip a part of the motor vehicle;

wherein the distal end of the flexible shaft is adapted to attach to a bore scope.

25. The motor vehicle inspection apparatus of claim 20 further comprising a bore scope attached to the distal end of the flexible shaft.

26. The motor vehicle inspection apparatus of claim 20, wherein the distal end of the flexible shaft includes threads for engaging with a bore scope.
