Abstract: An electronic device includes an array of daisy chained image sensors, with each image sensor including a pixel array. A host is coupled to an image sensor at an end of the array and is configured to insert identification codes. The identification codes include embedded data values to thereby indicate specific parts of the image data, and a set of identification codes comprising a first identification code to identify a start of a data stream and a second identification code to identify an end of the data stream.

Abstract: Data is encoded on an image sensor that has a plurality of pixels including one or more bio-sensing pixels and one or more data encoding pixels. The method includes applying a covering material selectively to the data encoding pixels depending on the data to be encoded, the covering material having a detectable difference in opacity relative to having no covering material present. The method includes reading the data encoding pixels, in the presence of light, and decoding data according to a pre-determined scheme depending on the presence of the covering material on the data encoding pixel. As bio-reagents are typically applied after manufacture of the image sensor, the image sensor can have information encoded for electronic detection subsequent to manufacture.

Abstract: An array of image sensors are connected in a daisy chained arrangement. The sensors in the array are addressed on the basis of the number of pixels each of them processes.

Abstract: An optical rotary encoder uses polarization difference imaging techniques to calculate an angle of orientation of a rotatable member. The optical rotary encoder includes a light source, a polarization sensor that has a polarizer and image sensing structure, and a polarizer disk fixed between to the rotatable and interposed between the light source and the polarization sensor.
