Electromagnetic interference sensor device and method and computer program
First Claim
1. A method comprising:
- receiving at a portable apparatus a radiofrequency interference signal which comprises a radiofrequency signal emitted by a device to be diagnosed as interfered by another signal transmitted from the portable apparatus;
storing data representative of the received interference signal in the portable apparatus separate from the device to be diagnosed;
submitting information identifying the device and 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, the portable apparatus 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.

11. An apparatus comprising:
-
at least one memory storing computer program code; and at least one processor;
in which the at least one memory with the computer program code is configured with the at least one processor to cause the apparatus at least to;store data representative of an interference signal emitted from a device to be diagnosed, in which the interference signal comprises a radiofrequency signal emitted by the device to be diagnosed as interfered by another signal transmitted from the apparatus; and
one ofuse information identifying the device 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 at least one memory so as to identify from the interference signal a fault in the device to be diagnosed, or send via an output port the information identifying the device and the data representative of the interference signal to a separate diagnostic computer for matching to a diagnostic signal pattern. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
