Image and part recognition technology
First Claim
1. A sensor array configured to detect an analyte comprising:
- an array of sensing elements arranged on a support in a pattern that identifies the array or analytes that bind to the array, said support comprising a front side and back side, wherein one or more sensing elements are configured to produce a detectable signal in the presence of an analyte, said signal detectable from either said front side or said back side; and
three or more alignment markers, wherein said three or more alignment markers are of different size than said sensing elements and are positioned proximate to the array, wherein alignment markers are positioned such that the mirroredness of the pattern is determined by the position of the alignment markers.

Abstract
A system and method for recognition of images may include the use of alignment markers. The image recognized may be a pattern from an array, a character, a number, a shape, and/or irregular shapes. The pattern may be formed by elements in an array such as an identification marking and/or a sensor array. More particularly, the system and method relate to discriminating between images by accounting for the orientation of the image. The size and/or location of alignment markers may provide information about the orientation of an image. Information about the orientation of an image may reduce false recognitions. The system and method of image recognition may be used with identification markings, biosensors, micro-fluidic arrays, and/or optical character recognition systems.

15. A sensor array configured to detect an analyte comprising:
- an array of sensing elements comprising a dot pattern that identifies the array or analytes that bind to the array on a support, each said support comprising a front side and a back side, and edges, wherein at least one dot of said dot pattern is configured to produce a detectable signal in the presence of an analyte, said signal detectable from either said front side or said back side; and
three or more alignment markers associated with said array and positioned on at least two of said edges said alignment markers positioned outside said dot pattern and being of different size than said dots such that the mirroredness of the pattern is determined by the position of the alignment markers. - View Dependent Claims (16, 17, 18)
- an array of sensing elements comprising a dot pattern that identifies the array or analytes that bind to the array on a support, each said support comprising a front side and a back side, and edges, wherein at least one dot of said dot pattern is configured to produce a detectable signal in the presence of an analyte, said signal detectable from either said front side or said back side; and
-
19. A plurality of sensor arrays configured to detect an analyte comprising:
a plurality of transparent, polymeric sensor arrays, at least a portion of which are positioned in different orientation relative to said other arrays, each sensor array comprising a front side, a back side, and a dot pattern that identifies the array or analytes that bind to the array, wherein at least one dot of said dot pattern on at least one sensor is configured to produce a detectable signal in the presence of an analyte, said signal detectable from either said front side or said back side of said sensor; and
three or more alignment markers positioned on each array such that the mirroredness of the pattern is determined by the position of the alignment markers.- View Dependent Claims (20, 21, 22)

23. A plurality of sensor arrays, each array having an orientation that is independent and different from all other arrays in said plurality of sensor arrays, said orientation comprising rotation and mirroredness, each array comprising a) sensing elements, arranged in a pattern that identifies the array or analytes that bind to the array, on a support, said support comprising a front side and back side, wherein one or more sensing elements are configured to produce a detectable signal in the presence of an analyte, said signal detectable from either said front side or said back side;
- and b) at least three alignment markers positioned proximate to the array, wherein alignment markers are positioned such that the orientation of each pattern is determined by the position of the alignment markers.
