Patent number: 6827695Abstract: A method of processing a raw acceleration signal, measured by an accelerometer-based compression monitor, to produce an accurate and precise estimated actual depth of chest compressions. The raw acceleration signal is filtered during integration and then a moving average of past starting points estimates the actual current starting point. An estimated actual peak of the compression is then determined in a similar fashion. The estimated actual starting point is subtracted from the estimated actual peak to calculate the estimated actual depth of chest compressions. In addition, one or more reference sensors (such as an ECG noise sensor) may be used to help establish the starting points of compressions. The reference sensors may be used, either alone or in combination with other signal processing techniques, to enhance the accuracy and precision of the estimated actual depth of compressions.Type: GrantFiled: October 25, 2002Date of Patent: December 7, 2004Assignee: Revivant CorporationInventors: James Adam Palazzolo, Ronald D. Berger, Henry R. Halperin, Darren R. Sherman

Patent number: 6766599Abstract: An inflatable liner for a boot, such as a snowboard boot. An oily chalk like substance consisting of 90% sweet starch, 9% lubricant, and 1% stearate is included between two sheets of plastic that make up bladder of the liner. The bladder is attached to the EVA of the liner before the EVA is folded, stitched, heated and molded. This allows the bladder to be attached while the EVA is still flat and allows attachment to be performed by machine stitching. The bladder is partially inflated before the EVA is heated and molded. The oily chalk like substance and the partial inflation of the bladder allows the installed bladder to pass through the heating and molding steps of the EVA without the two sheets that make up the bladder melting together. The design and installation of the bladder minimizes the amount of slipping of a wearer's foot and heel within the boot.Type: GrantFiled: February 20, 2001Date of Patent: July 27, 2004Assignee: DC Shoes, Inc.Inventor: Jai K. Baek

Patent number: 6752771Abstract: A method and device are disclosed for inflating an inflatable vest to assist the heart in patients suffering from heart failure. The inflation of the vest is synchronized with on-set of the systole phase of the heart, when the left ventricular compresses to force blood out of the heart and through the aorta. The inflated vest compresses the patient's chest and increases the intrathoracic pressure. This increase in pressure assists the heart in moving blood out of the heart and through the aorta. In addition, the vest is arranged to leave the patient's abdomen free of restraint so that the increase in intrathoracic pressure due to the vest moves blood into the abdomen, and to allow the abdomen to dynamically recoil in response to the vest inflation. In addition, ECG signals from electrodes applied to the patient are processed to trigger the vest inflation in real time with the current heartbeat cycle, such that the vest inflation is triggered when the heart begins to contract.Type: GrantFiled: January 29, 2001Date of Patent: June 22, 2004Assignee: Revivant CorporationInventors: Neil S. Rothman, Mark Gelfand, Daniel Burkhoff, Myron L. Weisfeldt

Patent number: 6739945Abstract: An optical sensor that includes a light source and a detector is located within a cavity in a polishing pad so as to face the surface that is being polished. Light from the light source is reflected from the surface being polished and the detector detects the reflected light. The electrical signal produced by the detector is conducted to a hub located at the central aperture of the polishing pad. The disposable polishing pad is removably connected, both mechanically and electrically to the hub. The hub contains electronic circuitry that is concerned with supplying power to the optical sensor and with transmitting the electrical signal to a non-rotating station. Several techniques are described for accomplishing these tasks. The system permits continuous monitoring of an optical characteristic of a surface that is being polished, even while the polishing machine is in operation, and permits the end point of the polishing process to be determined.Type: GrantFiled: September 29, 2001Date of Patent: May 25, 2004Assignee: StrasbaughInventors: David G. Halley, Gregory L. Barbour, Ben Smedley, Stephen H. Wolf

Patent number: 6712810Abstract: Methods and devices for occlusion of the fallopian tubes of a woman. The method involves thermally damaging the lining of the utero-tubal junction with relatively low power, followed by placement of a reticulated foam plug. In one embodiment, vascularized tissue grows into the plug and prevents or discourages formation of scar tissue around the plug. Another embodiment with a relatively small foam pore size encourages formation of a vascularized capsule around the plug. The presence of this vascularized capsule limits the patient's foreign body response, so that the capsule does not constrict around the plug. Also presented is a catheter designed for wounding the epithelial layer of the utero-tubal junction, and a method of using the catheter to form a long yet shallow lesion in the utero-tubal junction.Type: GrantFiled: March 16, 2001Date of Patent: March 30, 2004Assignee: Adiana, Inc.Inventors: Douglas C. Harrington, Victoria E. Carr-Brendenl, Brett S. Bowman

Patent number: 6699259Abstract: A minimally invasive device for performing direct cardiac massage including an inflatable bladder mounted on a rigid inflation tube. The rigid inflation tube is used to push the bladder into the sternocostal space through an incision in the upper abdomen just below the xiphoid process. A tear-away insertion sleeve is provided over the balloon, so that the device may easily be inserted in to the body. The insertion sleeve includes various features that assist in placement of the device and removal of the sleeve. After insertion into the sternocostal space and removal of the insertion sleeve, the bladder is repeatedly inflated and deflated to massage the heart and provide blood flow.Type: GrantFiled: January 6, 2003Date of Patent: March 2, 2004Assignee: Revivant CorporationInventors: Thomas J. Fogarty, Timothy James Ryan
