Abstract: The present invention monitors usage of an operating system at an application program interface (“API”) level and monitors changes in API functionality associated with an upcoming release to manage the version change process. A computer system is configured to track a collection of API functions associated with a first version operating system currently installed and to record the subset of API functions that have been called by applications during operation of the first version operating system. The computer system is further configured to manage the subset of API functions and generate a comparison between the subset and a list of API functions that have changed between a second version and the first version operating system. Finally, the computer system is configured to report the result of the comparison back to the user.

Abstract: A method of managing data fragments on computer readable storage media includes identifying an identical data segment within both of first and second data files, establishing a single instance of the identical data segment as a shared data fragment, modifying file headers associated with the first and second data files so that each file header associates with the shared data fragment, and reclaiming storage space that contains a redundant instance of the identical data segment. A data file or data fragment may be divided or further divided into data fragments if the file or fragment is identified as having a data segment that is identical to a data segment in a different data file or fragment. The method should require that amount of identical data reclaimed is greater than the amount of new header information stored with each fragment.

Abstract: A method, and apparatus are provided for implementing magnification and extension of keypads using a dynamic touch screen. The dynamic touch-screen generating device includes a processor coupled to a projector for generating and projecting an image onto a surface, and a camera for detecting a user activity on the projected image. The dynamic touch-screen generating device identifies a user selection and applies the identified user selection to an associated functional device, such as a cellular phone, PDA, or GPS navigator.
