6578966, Jun 17, 2003

Filed:

Mar 27, 2001

Appl. No.:

09/820283

Inventors:

Wolfgang Fink - Pasadena CA
Alfredo A. Sadun - San Marino CA

Assignee:

California Institute of Technology - Pasadena CA

International Classification:

A61B 302

US Classification:

351239

Abstract:

A method and apparatus for electronically performing a visual field test for a patient. A visual field test pattern is displayed to the patient on an electronic display device and the patients responses to the visual field test pattern are recorded. A visual field representation is generated from the patients responses. The visual field representation is then used as an input into a variety of diagnostic processes. In one embodiment of the invention, a series of visual test patterns of varying contrast are presented to a patient in order to construct a three-dimensional visual field representation wherein contrast sensitivity is plotted against a Z-axis.

Abstract:

A method and apparatus for electronically performing a visual field test for a patient. A visual field test pattern including a peripheral fixation point is displayed to the patient on an electronic display device and the patients responses to the visual field test pattern are recorded. A visual field representation is generated from the patients responses. The visual field representation is then used as an input into a variety of diagnostic processes. In one embodiment of the invention, a series of visual test patterns of varying contrast levels or colors are presented to a patient in order to construct a three-dimensional visual field representation wherein contrast sensitivity is plotted as the Z-axis.

International Classification:

G06F 19/00
G03B 37/00

US Classification:

701117, 701 2, 701300, 348144

Abstract:

A multi-agent autonomous system for exploration of hazardous or inaccessible locations. The multi-agent autonomous system includes simple surface-based agents or craft controlled by an airborne tracking and command system. The airborne tracking and command system includes an instrument suite used to image an operational area and any craft deployed within the operational area. The image data is used to identify the craft, targets for exploration, and obstacles in the operational area. The tracking and command system determines paths for the surface-based craft using the identified targets and obstacles and commands the craft using simple movement commands to move through the operational area to the targets while avoiding the obstacles. Each craft includes its own instrument suite to collect information about the operational area that is transmitted back to the tracking and command system. The tracking and command system may be further coupled to a satellite system to provide additional image information about the operational area and provide operational and location commands to the tracking and command system.

International Classification:

A61B 3/10

US Classification:

351211

Abstract:

A method and apparatus for electronically performing a visual field test for a patient. A visual field test pattern is displayed to the patient on an electronic display device and the patient's responses to the visual field test pattern are recorded. A visual field representation is generated from the patient's responses. The visual field representation is then used as an input into a variety of automated diagnostic processes. In one process, the visual field representation is used to generate a statistical description of the rapidity of change of a patient's visual field at the boundary of a visual field defect. In another process, the area of a visual field defect is calculated using the visual field representation. In another process, the visual field representation is used to generate a statistical description of the volume of a patient's visual field defect.

International Classification:

A61B 3/16

US Classification:

600398

Abstract:

An implantable intraocular pressure sensor device for detecting excessive intraocular pressure above a predetermined threshold pressure is disclosed. The device includes a pressure switch that is sized and configured to be placed in an eye, wherein said pressure switch is activated when the intraocular pressure is higher than the predetermined threshold pressure. The device is optically powered and transmits data wirelessly using optical energy. In one embodiment, the pressure sensor device is a micro electromechanical system.

International Classification:

A61N 1/36

US Classification:

607 54

Abstract:

A method for training a visual prosthesis includes presenting a non-visual reference stimulus corresponding to a reference image to a visual prosthesis patient. The visual prosthesis including a plurality of electrodes. Training data sets are generated by presenting a series of stimulation patterns to the patient through the visual prosthesis. Each stimulation pattern in the series, after the first, is determined at least in part on a previous subjective patient selection of a preferred stimulation pattern among stimulation patterns previously presented in the series and a fitness function optimization algorithm. The presented stimulation patterns and the selections of the patient are stored and presented to a neural network off-line to determine a vision solution.
