Patent number: 8718735Abstract: Confidence in a physiological parameter is measured from physiological data responsive to the intensity of multiple wavelengths of optical radiation after tissue attenuation. The physiological parameter is estimated based upon the physiological data. Reference data clusters are stored according to known values of the physiological parameter. At least one of the data clusters is selected according to the estimated physiological parameter. The confidence measure is determined from a comparison of the selected data clusters and the physiological data.Type: GrantFiled: June 3, 2011Date of Patent: May 6, 2014Assignee: Cercacor Laboratories, Inc.Inventors: Marcelo Lamego, Mohamed Diab, Ammar Al-Ali

Patent number: 8385996Abstract: A physiological sensor is adapted to removably attach an emitter assembly and a detector assembly to a fingertip. The emitter assembly is adapted to transmit optical radiation having multiple wavelengths into fingertip tissue. The detector assembly is adapted to receive the optical radiation after attenuation by the fingertip tissue. The sensor has a first shell and a second shell hinged to the first shell. A spring is disposed between the shells and urges the shells together. An emitter pad is fixedly attached to the first shell and configured to retain the emitter assembly. A detector pad is fixedly attached to the second shell and configured to retain the detector assembly. A detector aperture is defined within the detector pad and adapted to pass optical radiation to the detector assembly. A contour is defined along the detector pad and generally shaped to conform to a fingertip positioned over the detector aperture.Type: GrantFiled: April 13, 2009Date of Patent: February 26, 2013Assignee: Cercacor Laboratories, Inc.Inventors: Robert Smith, David Dalke, Ammar Al-Ali, Mohamed Diab, Marcelo Lamego
