Patent number: 10532170Abstract: Embodiments disclosed herein may include systems and methods for determining a patient's respiratory effort and blood oxygen saturation based on data acquired from a pulse oximetry sensor and analyzing the parameters in conjunction with each other. For example, the respiratory effort may be determined based on a photo-plethysmographic waveform generated from light attenuation detected by the sensor, and the blood oxygen saturation may be a pulse-based estimate of arterial blood oxygen saturation determined from the detected attenuation. Analysis of the parameters may enable detection and classification of apnea (e.g., obstructive or central) or another underlying cause for respiratory instability. Furthermore, the measured respiratory effort may be compared to respiratory effort supplied by a ventilator to ensure proper sensor placement before enabling automatic adjustment of ventilator settings.Type: GrantFiled: May 18, 2015Date of Patent: January 14, 2020Assignee: COVIDIEN LPInventors: Clark R. Baker, Jr., Michael P. O'Neil, Shannon E. Campbell, Gilbert Hausmann

Patent number: 6743473Abstract: The present invention provides a method and precursor for forming a metal and/or metal nitride layer on the substrate by chemical vapor deposition. The organometallic precursor has the formula of (Cp(R)n)xMHy−x, where Cp is a cyclopentadienyl functional group, R is a substituent on the cyclopentadienyl functional group comprising an organic group having at least one carbon-silicon bond, n is an integer from 0 to 5, x is an integer from 1 to 4, M is a metal, and y is the valence of the metal M. A metal, metal nitride, metal carbon nitride, or metal silicon nitride film is deposited on a heated substrate by thermal or plasma enhanced decomposition of the organometallic precursor in the presence of a processing gas, such as hydrogen, nitrogen, ammonia, silane, and combinations thereof, at a pressure of less than about 20 Torr. By controlling the reactive gas composition either metal or metal nitride films may be deposited.Type: GrantFiled: February 16, 2000Date of Patent: June 1, 2004Assignee: Applied Materials, Inc.Inventors: Vijay D.

Patent number: 6547934Abstract: The invention generally provides an apparatus and a method of removing metal oxides, particularly copper oxides and aluminum oxides, from a substrate surface. Primarily, the invention eliminates sputtering of copper oxide from the bottom of an interconnect feature onto the side walls of an interconnect feature, thereby preventing diffusion of the copper atom through the dielectric material and degradation of the device. The invention also eliminates sputtering of the copper oxides onto the chamber side walls that may eventually flake off and cause defects on the substrate. The method of reducing metal oxides from a substrate surface comprises placing the substrate within a plasma processing chamber, flowing a processing gas comprising hydrogen into the chamber, and maintaining a plasma of the processing gas within the chamber through inductive coupling.Type: GrantFiled: May 21, 1998Date of Patent: April 15, 2003Assignee: Applied Materials, Inc.Inventors: Barney M.
