Patent application number	Description	Published
20110012339	Push Lock Pipe Connection System and Disconnection Tool - A disconnection tool and system for disconnecting pipes which are connected through the connection system disclosed in application Ser. No. 12/365,000 and/or connections systems similar thereto. The disconnection tool of the present invention positions around a male end of a male pipe that is within a female end of a female pipe. The male end is locked within the female end with one or more locking members extending across a clearance that exists between the interior surface of the female end and the exterior surface of the male end. The one or more locking members engage both the male end of the male pipe and the female end of the female pipe. The disconnection tool has an insertion member that inserts into the clearance and disengages the one or more locking members from the male end of the male pipe or the female end of the female pipe.	01-20-2011
20110056526	VALVELESS INTAKE SCREEN AIRBURST SYSTEM - A method and apparatus for a backwash system for cleaning an underwater intake filter assembly. The backwash system includes an underwater tank coupled on one end to a source of compressed fluid and on the other end to the intake screen assembly. The backwash system includes a U-shaped release conduit that is adapted to release a predetermined quantity of fluid to the intake screen in order to clean the filter assembly of waterborne debris.	03-10-2011

20110029193	MONITORING BATTERY HEALTH IN AN HVAC SYSTEM - Systems and methods of monitoring battery health in an HVAC system. The charge state of a rechargeable battery and the number of amp-hours provided to or from the rechargeable battery are monitored. The number of amp-hours provided is recorded and an end-of-life condition is detected based on the number of amp-hours provided during the charge or discharge cycle. In some constructions, the end-of-life condition is detected by comparing the number of amp-hours provided during the charge or discharge cycle to a threshold. In some constructions, the end-of-life condition is detected by calculating a rate of change of the number of amp-hours provided during a charge or discharge cycle and comparing the rate of change to a threshold.	02-03-2011

20110025124	BI-DIRECTIONAL BATTERY VOLTAGE CONVERTER - A battery module for use with a vehicle electrical system. The battery module includes a bi-directional battery voltage converter, a first battery, and a second battery. A first relay selectively connects the first battery to the bi-directional battery voltage converter. A second relay selectively connecting the second battery to the bi-directional battery voltage converter. A controller selectively energizes the first relay, selectively energizes the second relay, and controls a direction of current through the bi-directional battery voltage converter.	02-03-2011
20110025125	BI-DIRECTIONAL BATTERY VOLTAGE CONVERTER - A method of balancing current in a vehicle electric system having a system bus, a first battery, a first bi-directional battery voltage converter selectively transferring a first current between the first battery and the system bus, a second battery, a second bi-directional battery voltage converter selectively transferring a second current between the second battery and the system bus, and a controller controlling the first bi-directional battery voltage converter and the second bi-directional battery voltage converter. The method includes sensing the first current and sensing the second current. The first bi-directional battery voltage converter and the second bi-directional battery voltage converter are controlled so that the first current and the second current are equal portions of a load current supplied to an electrical load connected to the system bus.	02-03-2011
20110025126	BI-DIRECTIONAL BATTERY VOLTAGE CONVERTER - A method of charging batteries in a vehicle electrical system having a system bus, a first switch selectively connecting a first battery with the system bus, a second switch selectively connecting a second battery with the system bus, and a controller monitoring a voltage of the vehicle electrical system and controllably opening and closing the first switch and the second switch. The method includes closing the first switch and opening the first switch if the voltage of the vehicle electrical system traverses a threshold value. The method also includes closing the second switch and opening the second switch if the voltage of the vehicle electrical system traverses the threshold value.	02-03-2011

20100137963	METHOD FOR FABRICATION OF LOW-POLARIZATION IMPLANTABLE STIMULATION ELECTRODE - A method for fabricating an implantable medical electrode includes roughening the electrode substrate, applying an adhesion layer, and depositing a valve metal oxide coating over the adhesion layer under conditions optimized to minimize electrode impedance and post-pulse polarization. The electrode substrate may be a variety of electrode metals or alloys including titanium, platinum, platinum-iridium, or niobium. The adhesion layer may be formed of titanium or zirconium. The valve metal oxide coating is a ruthenium oxide coating sputtered onto the adhesion layer under controlled target power, sputtering pressure, and sputter gas ratio setting optimized to minimize electrode impedance and post-pulse polarization.	06-03-2010
20100298901	IMPLANTABLE MEDICAL DEVICE FOR CARDIAC ELECTRICAL STIMULATION - A method and apparatus for reducing a patient's heart rate or blood pressure. The apparatus provides stimulation to the patient's atrial and/or nodal tissue within the associated refractory period of the ventricle but outside of an associated refractory period of the stimulated atrial an/or nodal tissue, responsive to detecting an occurrence of a ventricular depolarization following a preceding atrial depolarization.	11-25-2010
20100324643	Medical Devices Incorporating Carbon Nanotube Material and Methods of Fabricating Same - The present invention relates generally to medical devices; in particular and without limitation, to unique electrodes and/or electrical lead assemblies for stimulating cardiac tissue, muscle tissue, neurological tissue, brain tissue and/or organ tissue; to electrophysiology mapping and ablation catheters for monitoring and selectively altering physiologic conduction pathways; and, wherein said electrodes, lead assemblies and catheters optionally include fluid irrigation conduit(s) for providing therapeutic and/or performance enhancing materials to adjacent biological tissue, and wherein each said device is coupled to or incorporates nanotube structures or materials therein.
