Method and system for identification of assets
First Claim
1. A method for identifying an asset, the method comprising:
- illuminating an identification pattern for the asset with non-visible light, wherein the identification pattern comprises retroreflective material encoding identity information of the asset;
adjusting a shutter speed of an image sensor and a power of the non-visible light based on a motion state of the asset, wherein the motion state of the asset causes oscillating movement of the identification pattern, wherein the image sensor is configured to receive a response of the retroreflective material to the incident non-visible light;
selecting at least a portion of the response for processing based on a determination of a probable location of the identification pattern on the asset, wherein the probable location of the identification pattern is detected based on the oscillating movement of the identification pattern; and
identifying the asset based on decoded identity information, wherein the decoded identity information is obtained by processing the selected portion of the response of the retroreflective material.

Abstract
A method for identifying assets is provided. The method includes illuminating an identification pattern associated with the asset with non-visible light. The identification pattern includes retroreflective material that represents identity information of the asset. The method further includes adjusting either a shutter speed of an image sensor, or a power of the non-visible light, or both, based on motion state of the asset. The image sensor is configured to receive response of the retroreflective material to the non-visible light. Furthermore, the method includes the step of identifying the asset based on decoded identity information. The decoded identity information is obtained by processing the response of the retroreflective material.

9. A system for identification of an asset, the system comprising:
-
an identification pattern for the asset comprising retroreflective material, wherein the identification pattern encodes identity information of the asset; a light source for illuminating the identification pattern for the asset with non-visible light; an image sensor disposed to receive a response of the identification pattern to the incident non-visible light; and a processor configured to; generate control commands to control a shutter speed of the image sensor and a power supplied to the light source based on a motion state of the asset, wherein the motion state of the asset causes an oscillating movement of the identification pattern; select at least a portion of the response based on a determination of a probable location of the identification pattern, wherein the probable location of the identification pattern is detected based on the oscillating movement of the identification pattern; and process the selected portion of the response of the identification pattern to decode the identity information of the asset. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A system for identification of at least one asset in a hospital, the system comprising:
-
an identification pattern for the asset comprising retroreflective material, wherein the identification pattern encodes identity information of the asset; a light source for illuminating the identification pattern for the asset with non-visible light; an image sensor disposed to receive a response of the identification pattern to the incident non-visible light; and a processor configured to; generate control commands to control a shutter speed of the image sensor and a power supplied to the light source based on a motion state of the asset, wherein the motion state of the asset causes an oscillating movement of the identification pattern; select at least a portion of the response based on a determination of a probable location of the identification pattern, wherein the probable location of the identification pattern is detected based on the oscillating movement of the identification pattern; and process the selected portion of the response of the identification pattern to decode the identity information of the asset. - View Dependent Claims (17, 18, 19, 20, 21)
