  • Publication number: 20240053362
    Abstract: The present invention relates to a computer-implemented system [100] and method [300] for determining and monitoring multiple health conditions in a female body based on analytes present in a biological sample of said body. In an embodiment, the system [100] comprises test strips [110A-110N] coupled with a user device [130]. When said biological sample is poured on the test strip [110], the sample is pre-treated followed by reactions comprising (if) reaction between pre-treated sample and a detector reagent; (ii) reaction between each analyte of the reacted sample with corresponding biochemical reagent thereby producing a characteristic colour for each analyte. The information relating to the reactions is transmitted to the user device [130] that further determines a concentration value of each analyte based on said reactions. The user device [130] then analyses a comparison between the measured concentration value and pre-defined concentration value of each analyte to determine the fertility level.

  • Patent number: 9418405
    Abstract: A method of reducing motion blurring in digital radiography includes capturing at least one temporally coded blurred image of an object generated by using a coded pattern, and generating a de-blurred image from the at least one temporally coded blurred image by using the coded pattern and an estimate of a motion vector of the object. The at least one temporally coded blurred image is captured by using a total amount of generated light corresponding to at least a portion of radiation transmitted by the object. A digital radiography system is also provided.

  • Patent number: 8107723
    Abstract: A system for measurement of three-dimensional motion of an object is provided. The system includes a light projection means adapted for projecting, for distinct time intervals, light of at least two different colors with a cross-sectional pattern of fringe lines onto a surface of the object and also includes image acquisition means for capturing an image of the object during an exposure time, wherein the distinct time intervals are within the duration of the exposure time. The system further includes image processing means adapted for processing the image to obtain a different depth map for each color based on a projected pattern of fringe lines on the object as viewed from the position of the image acquisition means, to determine corresponding points on the depth maps of each color, and to determine a three-dimensional motion characteristic of the object based on the positions of corresponding points on the depth maps.
