Abstract: Method and apparatus for producing discrete filter rods includes a first conveyor for transporting filter segments of given length in a downstream direction. Three counter rotating transfer wheels receive the filter segments between spaced apart cleats on the circumference of the wheels. The first wheel receives the filter segments from the first conveyor and transfers the segments to the second wheel which in turn transfers the segments to the third wheel. Filter segments between the cleats on the third wheel are deposited upon a second conveyor with plug wrap thereon in precisely spaced apart relationship. Granular adsorbent material is filled into cavities between the filter segments, and a garniture folds the plug wrap around the filter segments and the filled cavities therebetween.

Abstract: A technique for segmenting a ribcage, e.g., in a chest radiograph, may involve determining whether or not the top of the image cuts through the lungs. The process may then proceed to segment the top and the sides of the ribcage. A dynamic programming technique may be used to perform the segmentation.

Abstract: Disclosed are methods, systems, and computer program products for identifying sensitive data from a user-entered input sequence based on user-defined criteria. According to one method, user-defined criteria for identifying sensitive data within user-entered input sequences that include sensitive data and padding data are received. A request for sensitive data from a requesting agent is presented. A user-entered input sequence that includes sensitive data and padding data is received in response to the request for sensitive data. Sensitive data is identified within the user-entered input sequence using the user-defined criteria. The identified sensitive data is provided to the requesting agent in response to the request for sensitive data.

Abstract: A digital design and technique may be used to implement a Manhattan Nearest Neighbor content addressable memory function by augmenting a serial content addressable memory design with additional memory and counters for bit serially accumulating in parallel and subsequently comparing in parallel all the Manhattan distances between a serially inputted vector and all corresponding vectors resident in the CAM. Other distance measures, besides a Manhattan distance, may optionally be used in conjunction with similar techniques and designs.
