A method is provided for encoding device independent multi-modal content including an arrangement comprising one or more of a plurality of tokens, where each token corresponds to a standard predefined effect. The method includes defining a token for one or more standard predefined effects, wherein the token is adapted for being mapped to one or more effect producing elements in a target device. One or more tokens are then composed for playback together as an arrangement.

A forms creation and processing system which identifies and locates the active areas of a form using forms landmarks. The present invention eliminates the need to place predefined registration marks onto a machine readable form. The active areas of a form are those which may contain a user created mark, such as a checkbox or a signature box. A form is preanalyzed at the same time that the active areas are being described. The aim of the preanalysis is to find a set of graphic shapes, i.e. landmarks, that can be found on the form independent of their location or orientation in the image. Examples of such landmarks include paragraphs of text, heavy black lines and gray scale areas. The analysis looks at the geometric distribution and regularities of the connected components to choose a set of landmarks. The landmarks and active areas on the form are stored in a forms control file. A forms interpreter uses the forms control file to locate and examine the active areas of an instance of a form to determine if a mark has been placed thereon.

A two-way fluid pressure relief valve having a valve body and two valve seats therein and two valve closure pieces operable on the seats. Springs force the closure pieces against the seats, and the fluid pressure will act in both directions for removing the closures from the seats and causing fluid pressure relief. A movable member engages the closure pieces to remove them from the seats and to also fluid-tightly seal with them up to the point of fluid pressure relief created by the springs.
