US Patent:

6572562, Jun 3, 2003

Filed:

Mar 6, 2001

Appl. No.:

09/801068

Inventors:

Sandra P. Marshall - San Diego CA

Assignee:

Eyetracking, Inc. - San Diego CA

International Classification:

A61B 1300

US Classification:

600558, 600544, 600545, 351209, 351246

Abstract:

An evaluation of affective brain function and, more particularly, to the monitoring of such function as an indication of the reception of visual stimulus. Such evaluation primarily involves analyzing dilation responses as a measure of whether the visual stimulus evokes a positive or negative affective response.

US Patent:

Filed:

Feb 23, 2006

Appl. No.:

11/361923

Inventors:

Sandra Peery Marshall - San Diego CA, US

Assignee:

EyeTracking, Inc. - San Diego CA

International Classification:

A61B 3/00
A61B 3/14

US Classification:

351246, 351210, 600558

Abstract:

A method for determining mental alertness level by monitoring point of gaze, pupillary movement, pupillary response, and other parameters in a subject performing a task, collecting the data in a database, analyzing the data in the database, and assigning the subject to a score indicating the subject's particular mental alertness level in real time.

International Classification:

A61B 3/00
A61B 3/14

US Classification:

351246, 351210, 600558

Abstract:

A method for determining mental proficiency level by monitoring point of gaze, pupillary movement, pupillary response, and other parameters in a subject performing a task, collecting the data in a database, analyzing the data in the database, and assigning the subject to a score indicating the subject's particular mental proficiency level in real time.

US Patent:

60900512, Jul 18, 2000

Filed:

Mar 3, 1999

Appl. No.:

9/261641

Inventors:

Sandra P. Marshall - San Diego CA

International Classification:

A61B 300

US Classification:

600558

Abstract:

Method and apparatus for correlating pupillary response to the cognitive activity of a subject undergoing an evaluation of cognitive activity during a task which involves monitoring and recording the point of gaze and pupillary response of the subject to the task, subjecting the recorded pupillary response to wavelet analysis in order to identify any dilation reflex of the subject's pupil during the task, and assigning a pupillary response value to the result of the wavelet analysis.

Filed:

Jul 24, 2019

Appl. No.:

16/521428

Inventors:

- Solana Beach CA, US
Sandra Marshall - San Diego CA, US

International Classification:

A61M 5/172
A61B 5/00
A61B 5/107
A61B 3/11

Abstract:

A video feed of one or more pupils of a patient can be received and processed to determine a raw measure of pupil size of the one or more pupils over time. Based on this raw measure, at least one of a) a depth of anesthesia for the patient, b) an index of cognitive activity for the patient, and c) a degree of perfusion of an anesthetic being administered to the patient to one or both hemispheres of a brain of the patient can be determined such that one or more actions can be caused to be performed. Related systems, methods, and article of manufacture are described.
