Patents by Inventor Vladimir Kudriavtsev

Vladimir Kudriavtsev has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10106883
    Abstract: A sputtering system having a processing chamber with an inlet port and an outlet port, and a sputtering target positioned on a wall of the processing chamber. A movable magnet arrangement is positioned behind the sputtering target and reciprocally slides behind the target. A conveyor continuously transports substrates at a constant speed past the sputtering target, such that at any given time, several substrates face the target between the leading edge and the trailing edge. In certain embodiments, the movable magnet arrangement slides at a speed that is at least several times faster than the constant speed of the conveyor. A rotating zone is defined behind the leading edge and trailing edge of the target, wherein the magnet arrangement decelerates when it enters the rotating zone and accelerates as it reverses direction of sliding within the rotating zone. In certain embodiments, magnet power and/or speed varies as function of direction of magnet travel.

  • Publication number: 20050222515
    Abstract: Devices, systems and methods of analyzing patient's heart, which are particularly focused on noninvasive techniques of interpreting cardiovascular sounds allow cost-effective and quick diagnosis at the early stages of cardiac dysfunctions. They are equally applicable to adult and pediatric patients. The invention recognizes that effective detection of abnormal cardiovascular sounds and heart lesions can be significantly enhanced by techniques, systems and computer media format that allow to present cardiovascular sounds in time and frequency while keeping signal resolution equally strong in both directions. Invention describes the format and method of constructing it to present the patient's cardiovascular sounds for the detection, identification and prognostication of the heart diseases. A truly unique and novel characteristic of the heart energy signature is its self-referencing feature.
