receive from the power transfer measurement circuit an indication of an amount of power transferred to a power receiving unit (PRU) of a specific user ([0090] efficiency of external charging device 48 by measuring the power out of external charging device 48 divided by the power into external charging device 48. The power out is gauged by the power induced in implantable medical device 16 (i.e. “amount of power transferred to the power receiving device of a specific user”) and is determined by multiplying the voltage of rechargeable power source 24 by the charging current in implantable medical device 16 (which is situated under cutaneous boundary 38 [0067]). As such the implantable medical device 16 is of a specific user ). These values are obtained by telemetry from implanted medical device 16 which is done using the Receive block 222 and telemetry antenna 218 [0088] [0090]. ).
Olson does not disclose/teach during a power transfer session, record a plurality of power transfer efficiency measurements for the specific user; determine a session power transfer efficiency value based on a first measure of central tendency for the plurality of power transfer efficiency measurements for the specific user; determine a system power transfer efficiency based on a second measure of central tendency for a plurality of session power transfer efficiency values; calculate a threshold power transfer efficiency for the PRU the specific user based on the system power transfer efficiency; determine, based on the system power transfer efficiency and the threshold power transfer efficiency for the PRU and the specific user, an indication of a relative location between the transmit antenna and the PRU that provides a session power transfer efficiency above the threshold power transfer efficiency; and control the user interface to output the indication of the relative location between the transmit antenna and PRU that provides the session power transfer efficiency above the threshold power transfer efficiency.
Skelton teaches during a power transfer session, record a plurality of power transfer efficiency measurements for the specific user and determine a session power transfer efficiency value (average recharge coupling efficiency) based on a first measure of central tendency for the plurality of power transfer efficiency measurements (Fig. 4 [0074] [0128]-[0130] processor 80 of the implantable medical device 14 may determine.. the average recharge coupling efficiency observed for each respective posture state (i.e. session) during the recharge session) for the specific user; determine a system power transfer efficiency based on a second measure of central tendency for a plurality of session power transfer efficiency values ([0130] predefined range of average recharge coupling percentage values identified as “system power transfer efficiency”); calculate a threshold power transfer efficiency for the PRU associated with the specific user (threshold efficiency set based on the predefined range of average recharge coupling percentage values "good," "poor," and "fair". The recharge coupling efficiency of the charging process may be monitored by the IMD ([0004]) which is a PRU associated with a user) based on the system power transfer efficiency (Fig. 9 [0130] a color coding scheme may be used in which the bar corresponding to a posture state may be filled in green if the average recharge coupling efficiency for that posture state was determined to be "good," filled in yellow if the average recharge coupling efficiency for that posture state was determined to be "fair," and filled in red if the average recharge coupling efficiency for that posture state was determined to be "poor." In such a case, each one of "good," "poor," and "fair" may correspond to a predefined range of average recharge coupling percentage values).
Skelton further teaches determine, based on the system power transfer efficiency ([0130] average recharge coupling percentage values) and the threshold power transfer efficiency for the PRU and the specific user ("good," "poor," and "fair"), an indication of a relative location between the transmit antenna and the PRU that provides a session power transfer efficiency above the threshold power transfer efficiency ([0130] the recharge coupling efficiency may vary during a recharge session due to the movement of secondary coil 91 relative to primary coil 113 (e.g., movement that results in changes to the distance and/or angle between the primary and secondary coils. For example, the movement of patient 12 (e.g., a transition from one posture state to another) may cause secondary coil 91 to move relative to primary coil 113. As such, the recharge coupling efficiency for that posture state was determined to be "good," being above “poor” is directly related to the location of the transmit antenna relative to the PRU).
It would have been obvious to a person of ordinary skill in the art to modify the processing circuitry of Olson to be configured to during a power transfer session, record a plurality of power transfer efficiency measurements for the specific user; determine a session power transfer efficiency value based on a first measure of central tendency for the plurality of power transfer efficiency measurements for the specific user; determine a system power transfer efficiency based on a second measure of central tendency for a plurality of session power transfer efficiency values; calculate a threshold power transfer efficiency for the PRU the specific user based on the system power transfer efficiency; determine, based on the system power transfer efficiency and the threshold power transfer efficiency for the PRU and the specific user, an indication of a relative location between the transmit antenna and the PRU that provides a session power transfer efficiency above the threshold power transfer efficiency in order for the user to identify the posture or position for optimal efficiency for future recharge sessions.
Olson in view of Skelton does not disclose/teach control the user interface to output the indication of the relative location between the transmit antenna and the PRU that provides the session power transfer efficiency above the threshold power transfer efficiency.
Takahashi teaches control the user interface to output the indication of the relative location between the transmit antenna and the PRU that provides the session power transfer efficiency above the threshold power transfer efficiency ([0067][0080] and Fig. 7 In the case where the receiving efficiency is less than or equal to a predetermined threshold, the receiving efficiency calculation unit 8124 determines that the power receiving apparatus 30 is not within the area 703 for transmission at the appropriate efficiency indicated in FIG. 7, and displays, in the display unit 27, a recommendation for moving the power receiving apparatus into a proper position (S1115). [0043] CPU 212 calculates the receiving efficiency by comparing the received power amount with the transmitted power).
It would have been obvious to a person of ordinary skill in the art to modify the user interface of Olson to output an indication of the relative location between the transmit antenna and the PRU that provides the session power transfer efficiency above the threshold power transfer efficiency in order to increase transmission efficiency ([0067][0080]), thereby reducing the amount of power transmitted.
As to claim 12, Olson in view of Skelton in view of Takahashi teaches the system of claim 11.
Olson does not disclose/teach wherein the threshold power transfer efficiency is further based on a user selected criteria
Skelton teaches wherein the threshold power transfer efficiency is further based on a user selected criteria ([0029] a patient may select a particular posture state to occupy during a recharge session if that posture state is associated with a desired level of recharge coupling efficiency. By selecting a posture state that provides desirable recharge coupling efficiency, the patient may be able to reduce the required recharge time).
It would have been obvious to a person of ordinary skill in the art to modify the system of Olson to wherein the threshold power transfer efficiency is further based on a user selected criteria so that the user can control and reduce the charging time.
