Abstract: The invention relates to method and apparatus for determining from a sample carrier containing an impregnated biological sample a sample region to be removed. The method comprises optically imaging the sample carrier into a digital matrix form, where the optical brightness of each physical location of the sample is represented by elements of the matrix; determining a first threshold value at least partly on the basis of the elements of the matrix; and calculating coordinates corresponding to the sample region to be removed from the sample carrier, the coordinates being such that the sample region contains only areas of the sample carrier having an optical brightness lower than or equal to said first threshold value. The invention allows for more efficient use of samples in sample cards.

Abstract: An XML parsing system includes a pattern-matching system 1 that receives an input stream 2 of characters corresponding to the XML document to be parsed, and provides an output 3 for subsequent processing in software by a processor 4. The pattern matching system 1 includes two main components, a controller in the form of a programmable state machine 5, which is programmed with an appropriate state transition diagram 6, and a character processing unit 7 in the form of a token and character handler. The programmable state machine 5 controls the character processing unit 7 to, e.g., compare characters in the input character stream 2 with other received or stored characters. The character processing unit 7 then provides feedback to the programmable state machine controller 5, e.g., as to whether the compared characters match, so that the programmable state machine controller 5 can then parse the received document accordingly.

Abstract: An innovative optical system and method is disclosed for analyzing and uniquely identifying high-order refractive indices samples in a diverse population of nearly identical samples. The system and method are particularly suitable for ultra-fine materials having similar color, shape and features which are difficult to identify through conventional chemical, physical, electrical or optical methods due to a lack of distinguishing features. The invention discloses a uniquely configured optical system which employs polarized sample light passing through a full wave compensation plate, a linear polarizer analyzer and a quarter wave retardation plate for producing vivid color bi-refringence pattern images which uniquely identify high-order refractive indices samples in a diverse population of nearly visually identical samples. The resultant patterns display very subtle differences between species which are frequently indiscernable by conventional microscopy methods.

Abstract: A check processing system comprises an image lift device which is provided for lifting an image of a check as the check is being transported along a check feed path. A MICR reader is provided for reading a MICR codeline from the check as the check is transported along the check feed path past the MICR reader. The image of the check is reoriented when the MICR reader is unable to read a MICR codeline from the image of the check due to misorientation of the check along the check feed path.
