| 20090149905 | CONFIGURATION OF PACING OUTPUT CHANNELS - During auto-threshold, autocapture, or other evoked response sensing, post-pace artifact is reduced by using a smaller coupling capacitor value than what is used when not in such an evoked response sensing configuration. This can be accomplished by borrowing another capacitor for use as the coupling capacitor. The borrowed capacitor can be a backup pacing capacitor from the same or a different pacing channel. The borrowed capacitor can also be a coupling capacitor from a different pacing channel. | 06-11-2009 |
| 20090177110 | IMPEDANCE MEASUREMENT AND DEMODULATION USING IMPLANTABLE DEVICE - An implantable medical device performs impedance measurement and demodulation, such as for obtaining lead impedance measurements, or thoracic impedance measurements, such as for extracting respiration, cardiac stroke, or fluid status information. A 4-point FIR filter demodulator can be used to demodulate a two-phase current excitation waveform. The demodulator can also be used to measure noise for triggering a noise response. Among other things, an increased excitation current level can be used when noise is deemed to be present. | 07-09-2009 |
| 20110071587 | Adaptive Safety Pacing - Methods and systems involve adjusting an energy used for safety pacing based on the capture threshold. The safety pacing energy may be adjusted prior to a capture threshold test. During the capture threshold test, backup safety paces are delivered using the adjusted pacing energy. Following suspension of automatic capture verification, the device may enter a suspension mode. During the suspension mode, safety pacing pulses are delivered using a pacing energy adjusted based on capture threshold. | 03-24-2011 |
| 20110159371 | IMPLANTABLE MEDICAL DEVICE INCLUDING EDDY CURRENT REDUCING BATTERY - An implantable device, such as a pacer, defibrillator, or other cardiac rhythm management device, can include one or more MRI Safe components. In an example, the implantable device includes a battery including a first electrode and a second electrode separate from the first electrode. The second electrode includes a first surface and a second surface. The second electrode includes a slot through the second electrode from the first surface toward the second surface. The slot extends from a perimeter of the second electrode to an interior of the second electrode. The slot is configured to at least partially segment a surface area of the second electrode to reduce a radial current loop size in the second electrode. | 06-30-2011 |
| 20110160803 | IMPLANTABLE DEVICE WITH BIAS FOR MRI - An ambulatory or implantable device, such as a pacer, defibrillator, or other cardiac rhythm management device, can tolerate magnetic resonance imaging (MRI) or other noise without turning on an integrated circuit diode by selectively providing a bias voltage that can overcome an expected induced voltage resulting from the MRI or other noise. | 06-30-2011 |
| 20110160806 | IMPLANTABLE MEDICAL DEVICE SWITCHING POWER SUPPLY INCLUDING MULTIPLE MODES - An implantable or other ambulatory medical device can include a magnetic field detector, such as configured to detect an intense magnetic field. In an example, the ambulatory or implantable medical device can include an inductive switching supply, such as including one or more of a peak current comparator, or a zero current comparator. In an example, the ambulatory or implantable medical device can include a controller circuit, configured to control a switch, such as to controllably charge an inductor included in the inductive switching supply. | 06-30-2011 |
| 20110160807 | IMPLANTABLE MEDICAL DEVICE INCLUDING CONTROLLABLY ISOLATED HOUSING - An implantable medical device or some other ambulatory medical device, such as a pacer, defibrillator, or other cardiac rhythm management device can include an electrical energy delivery circuit, such as including an integrated circuit comprising a first electrostimulation output terminal, a can terminal, and a switch control output. The ambulatory or implantable device can include at least two switches in series, each including a respective substrate electrically separate from the integrated circuit, and from each other, the switches configured to controllably isolate a conductive housing of the implantable medical device from the can terminal of the integrated circuit, such as in response to the switch control output. | 06-30-2011 |
| 20110160808 | IMPLANTABLE MEDICAL DEVICE INCLUDING ISOLATION TEST CIRCUIT - An implantable medical device can include a hermetically-sealed implantable housing, an exposed first conductor located on or near the housing, and at least one insulated second conductor located near the exposed first conductor. In an example, the implantable medical device can include an isolation test circuit to provide a test stimulus to the exposed first conductor and configured to measure a portion of the test stimulus coupled to the second conductor. | 06-30-2011 |

| 20110139215 | SOLAR CELL, MODULE, ARRAY, NETWORK, AND POWER GRID - The present invention teaches a solar cell, a solar module, a solar array, a network of solar arrays, and also a solar power grid suitable for providing power for industrial, residential and transportation use. A solar cell or solar module including a plurality of solar cells can be made in a structure configured to have the appearance of natural foliage. Accordingly, a solar array including a plurality of solar modules each including at least one solar cell can be made to resemble a palm tree, a deciduous tree, an evergreen tree, or other type of natural foliage. A network of solar arrays can be made to resemble a row or grove of palm trees, and thus meet the functional and aesthetic demands of landscape architecture. The network of solar arrays can extend for many miles alongside roads, highways, railways, pipelines, or canals, and can further include means for storing and transmitting electric power. In particular, a network of solar arrays can be in communication with recharging stations for use by electric and hybrid transportation vehicles. Accordingly, a network of solar arrays can form at least a portion of a solar power grid. | 06-16-2011 |
