<p>The present invention relates to devices and methods for automatically determining the use status of medical devices and more particularly to automatic power management based on said use status in electronic medical devices. Specifically, although not exclusively, the invention relates to power management of electronic stethoscopes (1 ), when such devices are turned on prior to the use of the stethoscope and to problems related to turning on such devices or relating to the time required for such electronic devices to become operable after turning on the device prior to use. Furthermore, the use status determination according to the invention may find use in other devices than stethoscopes, such as injector devices for administering medicaments or inhaling devices. The use status is according to the principles of the invention determined based on signals picked up by for instance sensor means detecting sound signals picked up by transducer means in an electronic stethoscope or by proximity detector means (such as capacity measuring means) or bio impedance measuring means, The present invention relates to devices and methods for automatically determining the use status of medical devices and more particularly to automatic power management based on said use status in electronic medical devices.

The method may further include calculating similarity indices between descriptor vectors of the plurality of reactions and comparing the similarity indices to identify at least one pair of similar reactions.</p> |
