20120247274 | METHOD OF MAKING A METAL TEREPHTHALATE POLYMER - Methods of making metal-terephthalate polymers from a polyester ethylene terephthalate or terephthalic acid produces high yield and high purity reaction products for a range of metals. Among the preferred metal compounds employed in the processes are metal oxides and metal hydroxides. The methods are preferably carried out at a low pressure and can produce metal-terephthalate polymer powders containing small crystals which can be employed to enhance properties of polymers or disperse metals in specific applications by thermal decomposition of metal-terephthalate polymers. | 10-04-2012 |

20150148868 | SYSTEM AND METHODS FOR ESTABLISHING A COMMUNICATION SESSION BETWEEN AN IMPLANTABLE MEDICAL DEVICE AND AN EXTERNAL DEVICE - A method is provided for establishing a communication session with an implantable medical device (“IMD”). The method includes configuring an IMD and an external device to communicate with one another through a protocol that utilizes a dedicated advertisement channel. The IMD periodically transmitting advertisement notices over the dedicated advertisement channel according to the protocol. The advertisement notices being transmitted periodically at an advertisement period over multiple cycles. The method further includes repeatedly scanning the advertisement channel, by the external device, for select scanning intervals in search of the advertisement notices, the scanning operation being repeated periodically at a scan period over the multiple cycles. The advertisement period and the scan period are independent of one another such that the advertisement and scan periods at least partially overlap intermittently after a number of cycles. When the external device detects one of the advertisement notices, the method includes establishing a communications link between the external device and the IMD. | 05-28-2015 |

20130079848 | EXTERNAL SYSTEMS FOR DETECTING IMPLANTABLE NEUROSTIMULATION LEADS AND DEVICES, AND METHODS OF USING SAME - Embodiments herein include an external system and method to detect an implanted lead coupled to an implanted neurostimulation device (INSD). The system and method comprise a handheld probe having electrodes configured to be positioned external to a surface of a patient and proximate to a region of the patient having the implanted lead for an implanted INSD. The electrodes are configured to measure a stimulation output from the implanted lead of the INSD. The system and method include a controller coupled to the electrodes to receive measured signals from the electrodes. The measured signals represent the stimulation output of the INSD. The controller processes the measured signals to obtain lead information. The system includes a user interface to present the lead information to a user. The lead information is indicative of at least one of an operation of the lead and a position of the lead. | 03-28-2013 |
20130096653 | EXTERNAL CHARGING DEVICE FOR CHARGING AN IMPLANTABLE MEDICAL DEVICE AND METHODS OF REGULATING DUTY CYCLE OF AN EXTERNAL CHARGING DEVICE - In one embodiment, an external charging device for recharging an implanted medical device, comprises: a battery for powering the external charging device; a coil for radiating RF power; drive circuitry for driving the coil according to a duty cycle; circuitry for generating a signal that is indicative of an amount of current flowing through the coil; and control circuitry for controlling the drive circuitry, wherein the control circuitry is operable to process the signal from the circuitry for generating to detect when a coil of the implantable medical device temporarily ceases absorbing RF power, the control circuitry modifying the duty cycle in response to detection of the coil of the implantable medical device temporarily ceasing absorbing RF power. | 04-18-2013 |
