Universal optical imaging and processing system
First Claim
1. A test media reader module comprising:
- a test media adapter configured to receive a test media that provides optical indication of a presence of a first analyte;
a housing configured to couple to the test media adapter, the housing having a barrier configured to separate the test media adapter from an interior of the housing, the barrier including a window having an interior side and an exterior side;
a membrane transparent to a wavelength useful for imaging a particular test media in the test media adapter, the membrane having at least one reactive region responsive to a proximate condition to change at least one optical characteristic of the at least one reactive region, the membrane overlying at least a portion of the exterior side of the window; and
an optical imager located proximal to the interior side of the window, wherein the optical imager is operative to capture an image including the particular test media in the test media adapter and the at least one reactive region of the membrane along an optical path extending through the window and the membrane.

Abstract
The disclosure is directed to a test media reader module including a housing, a membrane, and an optical imager. The housing is configured to receive a test media adapter and has a barrier wall configured to separate the test media adapter from an interior of the housing. The barrier wall includes a window having an interior side and an exterior side. The membrane is transparent to a wavelength useful for imaging test media in the test media adapter. The membrane has a reactive region and overlies at least a portion of the exterior side of the window. The optical imager is located interior to the housing and is configured to image the test media located on the exterior side of the window along an optical path extending through the window and the membrane.

14. A system, comprising:
-
a housing including a window; an optical imager located in the housing on a first side of the window; a membrane positionable on a second side of the window to overlie at least a portion of the window, wherein the membrane includes a transparent region and at least one reactive region responsive to a proximate condition to change optical characteristics of the at least one reactive region; a test media adapter configured to couple to the housing; and a test media positionable in the test media adapter such that the membrane is positioned between the window and the test media when the membrane is positioned on the second side of the window and the test media adapter is coupled to the housing, wherein the test media provides an optical indication of a presence of a first analyte; wherein the optical imager is configured to capture an image of the test media and the at least one reactive region of the membrane. - View Dependent Claims (15, 16, 17)
