ACOUSTIC WARNING LEVEL OPTIMIZATION IN AMBULATORY MEDICAL SYSTEMS
First Claim
1. An ambulatory medical device, the ambulatory medical device comprising:
- a function module to provide the intended functionality of the device;
a controller module to control the device;
a sound generation module with an acoustic transducer to produce an acoustic signal;
a signal generator to drive the acoustic transducer with a certain frequency, wherein the signal generation module is arranged within a housing of the device; and
a tuning module that varies the frequency used by the signal generator to drive the acoustic transducer and determines one or more frequencies that correspond to an optimum sound level of the acoustic signal, wherein the optimum sound level of the acoustic signal is a maximum sound level outside of the housing of the device and/or a maximum perceivable sound level as determined by a user.

Abstract
An ambulatory medical device is presented. The ambulatory medical device comprises a function module to provide the intended functionality of the device, a controller module to control the device, a sound generation module with an acoustic transducer to produce an acoustic signal and a signal generator to drive the acoustic transducer with a certain frequency. The signal generation module is arranged within a housing of the device. A tuning module varies the frequency used by the signal generator to drive the acoustic transducer and determines one or more frequencies that correspond to an optimum sound level of the acoustic signal outside of the housing of the device. The optimum sound level of the acoustic signal is a maximum sound level outside of the housing of the device, and/or a maximum perceivable sound level as determined by a user.

11. A method for configuring a sound generation module of an ambulatory medical device, the method comprising:
-
determining a test frequency; generating an acoustic signal with the sound generation module, applying the test frequency; obtaining a feedback signal; processing the feedback signal to a feedback value, wherein the feedback signal and value is related to the sound level of the acoustic signal outside of a housing of the device; repeating the determining, generating, obtaining and processing for at least once for another test frequency; and based on the test frequencies and their corresponding feedback values, determining at least one optimum frequency that corresponds to an optimum sound level of the acoustic signal, wherein the optimum sound level of the acoustic signal is a maximum sound level outside of the housing of the device and/or a maximum perceivable sound level as determined by a user. - View Dependent Claims (12, 13, 14)
