Electromagnetic interference sensor device and method and computer program
First Claim
1. A method comprising:
- receiving a radiofrequency interference signal emitted from a device to be diagnosed;
storing data representative of the received interference signal in a portable apparatus separate from the device to be diagnosed;
submitting the stored data representative of the received interference signal for matching to a diagnostic signal pattern stored in a database of predetermined diagnostic signal patterns; and
from the matching, outputting an indication of fault that is identified in the device to be diagnosed.

Abstract
A portable diagnostic apparatus is brought proximal to a device to be diagnosed. While the device to be diagnosed is operating, a radiofrequency interference signal emitted by the device is received at the portable apparatus and a data representation of it is stored. The data representation is submitted for matching to a diagnostic signal pattern stored in a database of predetermined signal patterns. From the matching is identified and output an indication of a fault in the device to be diagnosed. In one embodiment the submitting is to the database stored in the portable apparatus itself, and in another embodiment the submitting is outputting (data cable, wireless link) the stored data representation to a diagnostic computer such as a personal computer, a peer device, or a remote diagnostic center. The RF interference signal may be one stream and the portable apparatus receives at least a second stream and both streams are used for the matching.

8. An apparatus comprising:
-
a receiver configured to receive a radiofrequency interference signal that is emitted by a device to be diagnosed; a memory configured to store data representative of the received interference signal; and
one ofa processor configured to match the stored data representative of the interference signal to a diagnostic signal pattern of a database of predetermined diagnostic signal patterns stored in the memory so as to identify from the interference signal a fault in the device to be diagnosed, or an output port configured to send the data representative of the interference signal to a separate diagnostic computer for matching to a diagnostic signal pattern. - View Dependent Claims (9, 10, 11, 12, 13, 14)
