Assignee: BLANCCO TECHNOLOGY GROUP IP OY
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 16:
17. A mobile device comprising:
one or more sensors;
one or more actuators;
a display;
means for feeding a pre-defined control signal to a first actuator of the one or more actuators;
means for measuring, in response to the feeding, a first electric signal using a first sensor of the one or more sensors; means for comparing the first electric signal to one or more reference signals associated with the first actuator and the pre-defined control signal;
means for indicating, in response to the first electric signal failing to match the one or more reference signals according to one or more pre-defined criteria, a negative diagnosis to a user of the mobile device using one or more of the display and the one or more actuators; and
wherein the first actuator is a first vibrator and the first sensor is a first accelerometer and the mobile device further comprises means for:
measuring a background vibration signal using the first accelerometer when the first vibrator is inactive;
filtering, in response to the measuring of the first electric signal, the first electric signal based on the measured background vibration signal; and
performing the comparing using the filtered first electric signal.
