Abstract

The present disclosure discloses an implantable medical device and a method for optimizing power consumption of the implantable medical device. The implantable medical device comprises a time synchronization unit, a decoder, and a processor. The time synchronization unit may receive a time signal transmitted by an atomic clock of a satellite using radio waves upon occurrence of an event. The event may be an internal command or an external command to activate the time synchronization unit. Further, the decoder may decode the time signal in order to obtain a time data. Further, the processor may generate a log of the time data and metadata. The metadata indicates physiological parameters of a patient. The implantable medical device further comprises an amplifier to amplify the time signal carrying the time data when strength of the time signal is in a predefined range.

Claims

1. An implantable medical device comprising:

a time synchronization unit receives a time signal from a satellite having onboard atomic clocks by using radio waves, wherein the time signal is received upon occurrence of an event, and wherein the event is occurred on activation of an internal command or an external command;

a decoder to decode the time signal in order to obtain a time data; and

a processor configured to trigger a timer for maintaining a time log, indicating the time data along with metadata, without maintaining a Real-Time Clock (RTC), wherein the metadata indicates physiological parameters of a patient.

2. The implantable medical device of claim 1, further comprise an amplifier to amplifying the time signal carrying the time data based on strength of the time signal, wherein the amplifier generates a warning signal when the time signal is obtainable at a highest amplification factor.

3. The implantable medical device of claim 1, wherein the internal command is executed at predefined time intervals.

4. The implantable medical device of claim 1, wherein the external command is executed on a need only basis when the implantable medical device needs to be activated.

5. A method for optimizing a power consumption of an implantable medical device, wherein the method comprising:

receiving, by a time synchronization unit, a time signal from a satellite having onboard atomic clocks by using radio waves, wherein the time signal is received upon occurrence of an event, and wherein the event is occurred on activation of an internal command or an external command;

decoding, by a decoder, the time signal in order to obtain a time data; and

triggering, by a processor, a timer for maintaining time log, indicating the time data along with metadata, without maintaining a Real-Time Clock (RTC), wherein the metadata indicates physiological parameters of a patient.

6. The method of claim 5, further comprising

amplifying, by using an amplifier, the time signal carrying the time data based on strength of the time signal, and

generating, by the amplifier, a warning signal when the time signal is obtainable at a highest amplification factor.

7. The method of claim 5, wherein the internal command is executed at predefined time intervals.

8. The method of claim 5, wherein the external command is executed on a need only basis when the implantable medical device needs to be activated.
