Publication number: 20240350087Abstract: Systems and methods are disclosed for proximity sensing in physiological sensors, and more specifically to using one or more proximity sensors located on or within a physiological sensor to determine the positioning of the physiological sensor on a patient measurement site. Accurate placement of a physiological sensor on the patient measurement site is a key factor in obtaining reliable measurement of physiological parameters of the patient. Proper alignment between a measurement site and a sensor optical assembly provides more accurate physiological measurement data. This alignment can be determined based on data from a proximity sensor or sensors placed on or within the physiological sensor.Type: ApplicationFiled: May 3, 2024Publication date: October 24, 2024Inventors: Thomas B.

Publication number: 20150005600Abstract: A finger-placement sensor tape aligns and removably secures a finger to a sensor pad of a reusable finger-clip optical sensor so as to assure the finger is repeatably aligned between the sensors emitters and detectors and that the finger stays aligned during a test procedure. The sensor tape has a double-sided tape layer having a silicon-based adhesive on a finger side and an acrylic adhesive on a sensor-side. An aperture is defined in the tape layer so as to allow emitters disposed in a top sensor pad to emit light through the tape layer to detectors disposed in a bottom sensor pad. A finger-side release layer is removably disposed over the silicon-based adhesive. A sensor-side release layer is removably disposed over the acrylic adhesive.Type: ApplicationFiled: March 13, 2014Publication date: January 1, 2015Inventors: Thomas B.

Patent number: 8868147Abstract: The invention relates generally to a probe interface method and apparatus for use in conjunction with an optical based noninvasive analyzer. More particularly, an algorithm controls a sample probe position and attitude relative to a skin sample site before and/or during sampling. For example, a sample probe head of a sample module is controlled by an algorithm along the normal-to-skin-axis. Preferably, the sample probe head is positioned in terms of 3-D location in the x-, y-, and z-axes and is attitude orientated in terms of pitch, yaw, and roll. Further, attitude of the probe head is preferably orientated prior to contact of the sample probe head with the tissue sample using indicators, such as non-contact distance feedback from capacitance sensor, contacting or non-contacting optical sensors, and/or contact electrical sensors.Type: GrantFiled: May 21, 2008Date of Patent: October 21, 2014Assignee: GLT Acquisition Corp.Inventors: Timothy W.

Patent number: RE41333Abstract: A method of multi-tier classification and calibration in noninvasive blood analyte prediction minimizes prediction error by limiting co-varying spectral interferents. Tissue samples are categorized based on subject demographic and instrumental skin measurements, including in vivo near-IR spectral measurements. A multi-tier intelligent pattern classification sequence organizes spectral data into clusters having a high degree of internal consistency in tissue properties. In each tier, categories are successively refined using subject demographics, spectral measurement information and other device measurements suitable for developing tissue classifications. The multi-tier classification approach to calibration utilizes multivariate statistical arguments and multi-tiered classification using spectral features.Type: GrantFiled: January 27, 2005Date of Patent: May 11, 2010Assignee: Sensys Medical, Inc.Inventors: Thomas B.
