Power optmization in a medical implant based system

#Embodiments of the disclosure relate to power optimization in a medical implant based system.

#A medical implant based system includes a medical controller and a medical implant. The medical implant is present inside the body of a living organism and the medical controller is external. Power consumption of the medical implant is one of the major determinants of lifetime of the medical implant. The power consumption in a medical implant transceiver forms a significant portion of the overall power consumption in the medical implant. Hence, it is desired to optimize power consumption in the medical implant transceiver to increase lifetime of the medical implant.

#The power in the medical implant transceiver is utilized for performing various functions. In one example, power consumption in the medical implant transceiver is dominated by a listen mode of the medical implant transceiver. In the listen mode, the medical implant transceiver wakes up periodically, for example every 4 seconds, and searches for a signal for association. The signal for association can be transmitted for a time period greater than 4 seconds. The medical implant transceiver that wakes up at beginning of transmission of the signal for association has to wait till end of the transmission of the signal for association to perform further functions. The waiting leads to power wastage.

#FIG. 1 illustrates an environment 100 including a medical implant based system. The environment 100 includes one or more medical implant transceivers, for example a medical implant transceiver 105, hereinafter referred to as the implant transceiver 105, and one or more medical controller transceivers, for example a medical controller transceiver 110, hereinafter referred to as the controller transceiver 110. The implant transceiver 105 is present inside a living organism to monitor health and to transmit health details to the controller transceiver 110. The implant transceiver 105 is included in a medical implant. The controller transceiver 110 is included in a medical controller.

#The implant transceiver 105 includes or is connected to an antenna 115a to transmit and receive signals. The implant transceiver 105 can also include or be connected to sensors, for example a sensor 120. Each sensor monitors and senses various health details. Examples of the sensors include, but are not limited to, pacemakers and brain sensors. The controller transceiver 110 also includes or is connected to an antenna 115b to transmit and receive signals.

#The implant transceiver 105, and the controller transceiver 110, can communicate with each other in a Medical Implant Communication Service (MICS) frequency band. The MICS frequency band ranges from 402 megahertz (MHz) to 405 MHz. The implant transceiver 105 and the controller transceiver 110 can also communicate with each other in a Medical Data Services (MEDS) frequency band. The MEDS frequency band ranges from 401 MHz to 402 MHz, and from 405 MHz to 406 MHz. The frequency band can be referred to as a band of channels.
