A method of tracking software application downloads over the internet in which clicking on a web advertisement for a software application causes a user's device web browser to link to a tracking server which creates a unique identifier which is stored by the user's device browser, and also on the tracking server together with an indication of the web page including the advertisement. The user's device web browser then downloads the desired software application which includes executable code which, upon first execution, suspends the downloaded application and starts the browser, directing it to the tracking server and sending the unique identifier to the tracking server together with identification of the device and downloaded software application. The tracking server then uses the unique identifier to correlate the information on the downloaded application with the information originally stored at the time of clicking on the web advertisement.

A method of analysing tachometer and vibration response data from an apparatus having one or more rotary components is provided. The method comprises the steps of: providing vibration response data and corresponding tachometer data from the apparatus for a period over which a rotary component of the apparatus varies in rotational speed, the tachometer data being for that component; repeatedly performing at intervals throughout the period the sub-steps of: determining a forcing frequency of the component from the tachometer data and a corresponding vibration response frequency of the apparatus from the vibration response data, comparing the forcing and vibration response frequencies to determine the relative phase difference between the frequencies, and determining the corresponding amplitude of the vibration response from the vibration response data; and plotting the relative phase differences and vibration amplitudes on a polar diagram. The plot trajectory is characteristic of the behavior of the apparatus over the period.

A method for monitoring the health of a system comprises performing at each of a plurality of times the steps of: constructing a condition signature from a plurality of condition indicators including (a) a plurality of vibration measurements acquired from the system or (b) one or more vibration measurements and one or more performance parameter measurements acquired from the system; predicting a normal signature from a model defining one or more inter-dependencies between said condition indicators, the normal signature corresponding to the condition signature for a healthy system; comparing the condition signature with the normal signature; and registering an event if the condition signature differs from the normal signature by more than a predetermined threshold.
