| 20090181302 | ELECTROLYTE ADDITIVE FOR PERFORMANCE STABILITY OF BATTERIES - An organic additive to an electrolyte for a battery cell in an implantable medical device is presented. At least one organic additive is selected from a group comprising one of lithium salicylate, hydroxyphthalic anhydride, a hydroxybenzoic acid, salicylate ester, salicylamide, and salicylanilide. | 07-16-2009 |
| 20090210034 | System and Method for Monitoring Power Source Longevity of an Implantable Medical Device - Power source longevity monitor for an implantable medical device. An energy counter counts the amount of energy used by the implantable medical device. An energy converter converts the energy used into an estimate of remaining power source longevity and generating an energy longevity estimate. A voltage monitor monitors the voltage of the power source. A voltage converter converts the voltage monitored by the voltage monitor into an estimate of remaining longevity of the power source and generating a voltage longevity estimate. A calculator is operatively coupled to the energy converter and to the voltage converter and predicts the power source longevity using the energy longevity estimate early in the useful life of the power source and using the voltage longevity estimate later in the useful life of the power source. | 08-20-2009 |
| 20100136426 | RESISTANCE-STABILIZING ADDITIVES FOR ELECTROLYTE - A resistance-stabilizing additive to an electrolyte for a battery cell in an implantable medical device is presented. At least one resistance-stabilizing additive is selected from a group comprising an electron withdrawing group, an aromatic diacid salt, an inorganic salt, an aliphatic organic acid, an aromatic diacid, and an aromatic monoacid. | 06-03-2010 |
