Abstract

Abstract A compact, handheld imaging apparatus which can be used to capture high-quality iris images for identification of a person. The handheld iris imager is non-invasive and non-contacting and comprises a camera, a cold mirror, a lens, and an illuminator. The imager has sensors and indicators which assist a user in aligning and focusing the device. The imager also automatically captures the image when proper positioning is achieved. A template of the image is then transmitted to a receiver in a vehicle or other asset and compared to a database of previously stored templates of images to identify the person. The imager is part of a security module to protect access to an asset such as a vehicle or residence. The vehicle or residence cannot be unlocked and used unless a user has been identified and authorized by the imager and a controller system.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 190 words
A system for providing access to a vehicle or other asset, comprising: an imager comprising: iris acquisition means having a front surface for obtaining an image of an iris of an eye; a lens having an image plane disposed in front of the front surface of the iris acquisition means; a mirror disposed on a side of the lens opposite the iris acquisition means; an illuminator disposed along a side of the mirror; a first memory for storing an iris image obtained by the iris acquisition means; a processor for extracting a template from the stored iris image; and a communications interface for transmitting the template to the controller system; and a controller system comprising: communications interface for receiving the template from the imager; a second memory for storing at least one template of at least one image of an iris of at least one person's eye; a processor for comparing the received template with the at least one template in the second memory to identify the person; and a lock interface coupled to the processor for receiving a command from the processor responsive to the results of the comparison.
Claim 2
Independent Claim 190 words
A system for providing access to a vehicle or other asset, comprising: an imager comprising: iris acquisition means having a front surface for obtaining an image of an iris of an eye; a lens having an image plane disposed in front of the front surface of the iris acquisition means; a mirror disposed on a side of the lens opposite the iris acquisition means; an illuminator disposed along a side of the mirror; a first memory for storing an iris image obtained by the iris acquisition means; a processor for extracting a template from the stored iris image; and a communications interface for transmitting the template to the controller system; and a controller system comprising: communications interface for receiving the template from the imager; a second memory for storing at least one template of at least one image of an iris of at least one person's eye; a processor for comparing the received template with the at least one template in the second memory to identify the person; and a lock interface coupled to the processor for receiving a command from the processor responsive to the results of the comparison.
Claim 3
Dependent Claim 22 words
The system according to claim 1 , wherein the iris acquisition means comprises a camera, and the mirror is a cold mirror.
Claim 4
Dependent Claim 28 words
The system according to claim 2 , wherein the camera is sensitive to light having a wavelength in a range between about 400 nm and about 1100 nm.
Claim 5
Dependent Claim 37 words
The system according to claim 2 , wherein the mirror reflects light having a wavelength in a range between about 400 nm and about 700 nm and passes light having a wavelength greater than about 700 nm.
Claim 6
Dependent Claim 16 words
The system according to claim 1 , further comprising an input device for receiving user input.
Claim 7
Dependent Claim 34 words
The system according to claim 1 , wherein the illuminator emits light having a wavelength in a range between about 680 nm and about 900 nm towards the iris of the eye being imaged.
Claim 8
Dependent Claim 47 words
The system according to claim 1 , wherein the processor sends an unlock command via the lock interface to unlock the vehicle or other asset if the comparison indicates a substantial match between the received template and the at least one template stored in the second memory.
Claim 9
Independent Claim 163 words
A method of providing access to a vehicle or other asset responsive to the identification of a person, comprising: (a) storing image information of the iris of at least one person's eye in a memory in a controller system; (b) illuminating an eye of an unidentified person having an iris with an imager; (c) obtaining an image of the iris of the unidentified person; (d) determining if the image is an image of sufficient quality for a step (f) of extracting; (e) repeating steps (b) through (d) until the image of sufficient quality is obtained; (f) extracting an iris template if the image is of sufficient quality; (g) transmitting the iris template from the imager to the controller system; (h) at the controller system, receiving the iris template from the imager and comparing the iris template with the stored image information to identify the unidentified person; and (i) providing access to the vehicle or other asset responsive to a result of the comparing.
Claim 10
Independent Claim 163 words
A method of providing access to a vehicle or other asset responsive to the identification of a person, comprising: (a) storing image information of the iris of at least one person's eye in a memory in a controller system; (b) illuminating an eye of an unidentified person having an iris with an imager; (c) obtaining an image of the iris of the unidentified person; (d) determining if the image is an image of sufficient quality for a step (f) of extracting; (e) repeating steps (b) through (d) until the image of sufficient quality is obtained; (f) extracting an iris template if the image is of sufficient quality; (g) transmitting the iris template from the imager to the controller system; (h) at the controller system, receiving the iris template from the imager and comparing the iris template with the stored image information to identify the unidentified person; and (i) providing access to the vehicle or other asset responsive to a result of the comparing.
Claim 11
Dependent Claim 21 words
The method according to claim 8 , wherein access to the vehicle or other asset is provided via a lock interface.
Claim 12
Dependent Claim 24 words
The method according to claim 8 , wherein determining if the image is an image of sufficient quality comprises focus assessment processing the image.
Claim 13
Dependent Claim 20 words
The method according to claim 8 , wherein vehicle or other asset is unlocked if the comparing identifies the person.
Claim 14
Dependent Claim 54 words
