In one embodiment, data containers in an active file system of a storage object are first scanned. Remaining images (e.g., snapshots of the file system) are arranged in a chronological order based on the age of such images in the storage object. In some instances, to perform a metadata scan of a given image, the storage server compares each data container in the given image to a corresponding data container in a prior image (from the chronological order) to identify any non-identical data blocks (i.e., blocks that are not common between the data containers of the two images) in each data container. The metadata scanner then generates metadata only for the non-identical data blocks in each data container and skips metadata generation for any remaining data blocks. | 05-22-2014 |

The technique bypasses the usual consistency point process for new or modified data blocks representing potential remedial changes. At a consistency point, dirty data blocks representing the potential remedial changes are written to a change log file residing outside the volume. The modified data blocks are written in sequential order to logical blocks of the change log file. In response to a user input indicating that a potential change should be committed, the corresponding modified data blocks are read from the change log file in the order in which they were written to the change log file, and they are written to persistent storage in that order. | 12-18-2014 |

20150289781 | Apparatus and method for intravascular catheter navigation using the electrical conduction system of the heart and control electrodes - A new apparatus, algorithm, and method (all called Invention) are introduced herein to support navigation and placement of an intravascular catheter using the electrical conduction system of the heart (ECSH) and control electrodes placed on the patient's skin. According to the present Invention, an intravascular catheter can be guided both in the arterial and venous systems and positioned at different desired locations in the vasculature in a number of different clinical situations. The catheter is connected to the apparatus using, for example, sterile extension cables, such that the apparatus can measure the electrical activity at the tip of the catheter. Another electrode of the apparatus is placed for reference on the patient's skin. In one embodiment of the present Invention, a control electrode is placed on the patient's chest over the manubrium of the sternum below the presternal notch. In this case, if a catheter is inserted in the venous system, for example in the basilic vein, the Invention will indicate if the tip of the catheter navigates from the insertion point in the basilic vein into the subclavian vein on the same side, into the subclavian vein counter laterally, into the jugular vein, into the superior vena cava, into the cavoatrial junction (CAJ), into the right atrium (RA), into the right ventricle (RV), or into the inferior vena cava (IVC). For the same location of a control electrode, if a catheter is inserted in the arterial system, the Invention will indicate when the tip of the catheter is navigating into the arch of the aorta, into the right coronary artery, into the left circumflex artery, or into the left ventricle (LV). In another embodiment of the present Invention, a control electrode can be placed on the sternum over the xiphoid process. In one embodiment of the present invention, a catheter can be inserted in the arterial systems by arterial radial, brachial or axillary access. In another embodiment of the present Invention, a catheter may be inserted into either the arterial or the venous systems by femoral or saphenous access. In one aspect of the present Invention, navigation maps are introduced for different locations in the vasculature which allow for easy identification of the location of the catheter tip. In another aspect of the present Invention, a novel algorithm is introduced to compute a navigation signal in real time using electrical signals from the tip of the catheter and from control electrodes. In another aspect of the present Invention, a novel algorithm is introduced to compute in real time navigation parameters from the navigation signal computes according to the present Invention. In another aspect of the present Invention, a method is introduced which makes use of the navigation signal to allow for placing an intravascular catheter at a desired location in the vasculature relative to the ECSH and to the control electrodes placed on the skin. In another aspect of the present Invention, the electrical signals obtained from control electrodes and from the tip of the catheter may be generated by the natural ECSH, e.g., the sino-atrial node (SAN), by artificial (implanted) pacemakers or by electrical generators external to the body. In yet another aspect of the Invention, an apparatus is introduced which supports data acquisition required by the computation of a navigation signal according to the present Invention. | 10-15-2015 |

20120059270 | APPARATUS AND METHOD FOR CATHETER NAVIGATION USING ENDOVASCULAR ENERGY MAPPING - Devices and methods for obtaining and using endovascular electrograms in a number of clinical applications and settings are disclosed. In one embodiment, a method is disclosed for locating an indwelling medical device within a vasculature of a patient. The method comprises identifying an endovascular ECG waveform complex from an endovascular ECG signal associated with the indwelling medical device, then calculating an absolute value of the energy of the endovascular ECG waveform complex over a predetermined segment thereof. A position of the medical device within the vasculature is then determined by observation of the absolute value of the energy of the predetermined segment of the endovascular ECG waveform complex. | 03-08-2012 |
