Appl. No.:

09/393817

Inventors:

Hessam Ghiassi - Rockville MD
Robert D. Rosenthal - Gaithersburg MD

Assignee:

Futrex Inc. - Gaithersburg MD

International Classification:

A61B 600

US Classification:

600473, 600476, 600479, 600480, 600481, 600440, 600492, 600495, 606 12, 606 13, 359503, 359515, 359516, 359517, 2503161

Abstract:

In a self-service health parameter measuring apparatus and method, a persons elbow is placed at a spatial reference point, and means surrounding a users forearm locate an infrared body fat apparatus measurement point at a substantially fixed distance from the spatial reference point. Motor drive means adjustably tighten or loosen a cuff around an upper arm so that measurements on each user are made at substantially the same pressure of the measuring apparatus against a forearm irrespective of the size of the arm. In a preferred form, the preselected measurement pressure is achieved by inflating the cuff to a maximum level, and allowing deflation. Measurement is made when a lower, second preselected level is reached. Blood pressure is also measured in connection with the inflation and deflation operation. Further health parameters may be measured.

Appl. No.:

10/387845

Inventors:

Robert D. Rosenthal - Silver Spring MD, US

Assignee:

Futrex, Inc. - Gaithersburg MD

International Classification:

A61B005/00

US Classification:

600316, 600322

Abstract:

A method and apparatus for measuring a blood analyte concentration using an inexpensive, low precision sensor device is provided. One embodiment of the method includes obtaining energy absorption measurement data through a body part of an individual. A plurality of indicator variables are subsequently calculated from the energy absorption measurement data. An indicator variable from the plurality of indicator variables having the highest correlation to blood glucose level is determined, and a first optical term based on the indicator variable with the highest correlation to blood glucose level is allocated to form a regression analysis equation. An estimated value of the blood analyte concentration using the regression analysis equation is calculated.

Appl. No.:

11/006546

Inventors:

Robert Rosenthal - Silver Spring MD, US

International Classification:

A61B005/00

US Classification:

600316000

Abstract:

A method and system for detection of potentially undesirable and/or dangerously low levels of blood glucose based on heart rate measurements in conjunction with initial calibration of blood glucose levels, and continuous monitoring of heart rate and estimation of blood glucose levels during periods of sleep.

Appl. No.:

11/956828

Inventors:

Robert D. Rosenthal - Silver Spring MD, US

Assignee:

Futrex Inc. - Gaithersburg MD

International Classification:

G01N 21/25

US Classification:

356 39

Abstract:

In one aspect, the present invention provides systems and methods for non-invasively determining the amount of an analyte in a subject's blood using a set of light sources and a set of light detectors for measuring optical density. Advantageously, in embodiments of the invention, the light sources are operated such that each of the light sources outputs light at the same time, thereby concurrently illuminating the fingertip with light from each light source, and while the fingertip is illuminated by the light sources, a data processor reads data output from each light detector substantially simultaneously.

Appl. No.:

6/603821

Inventors:

Robert D. Rosenthal - Gaithersburg MD

Assignee:

Trebor Industries, Inc. - Gaithersburg MD

International Classification:

G06F 1520
G01N 2100
G01J 348

US Classification:

364550

Abstract:

In the quantitative analysis of a sample by computing constituents from optical absorptivity data at different wavelengths, optical absorptivity data values for selected nominal wavelengths are obtained by curvilinear interpolation from measured optical absorptivity data values obtained by use of narrow band width filters. The computed optical data values are utilized to compute percentage constituents by means of algorithms which may include one or more first or second derivatives.

Inventors:

Robert D. Rosenthal - Gaithersburg MD

Assignee:

Neotec Corporation - Silver Spring MD

International Classification:

G01N 2122

US Classification:

356201

Abstract:

A technique for automatic detection of abnormalities, particularly pathology, in biomedical specimens. Light transmittance or reflectance data over a large number of wavelengths for numerous samples are correlated mathematically with conventional clinical results to select test wavelengths and constants for a correlation equation. Optical instrumentation with an analog or digital computer applies the resulting correlation equation to the spectral data on a given specimen at the test wavelengths to determine quantitatively the presence of the abnormality.

International Classification:

G01N 3350

US Classification:

250341

Abstract:

An improved near-infrared quantitative analysis instrument is disclosed comprising a removable finger insert which facilitates properly aligning and fitting and individual user's finger into the optical system of the analysis instrument. The finger insert according to the present invention also prevents the analysis instrument's optical system from being damaged by foreign matter typically introduced by a user's finger. The finger insert can also be provided with filters which will enable the insert to be used to as an optical standard for the analysis instrument.
