IPC: G06F11/36
Filed: 1996-01-15
Abstract: A method of analyzing a plurality of code segments to determine the similar static and dynamic features of the code segments compares the static anddynamic features of each of the code segments. Each code segment is comprised ofone or more lines of program instructions. One or more predetermined static attributes are extracted from each code segment. Each code segment is then run so that the dynamic attributes of the code segment can be determined. The dynamic attributes are extracted from each code segment and a distrance function is computed which is based on the extracted static and dynamic attributes for a given pair of code segments. The distance function produces a distance measurement which indicates the relative degree of similarity between the given pair of code segments.

Title: Transparent call progress
Inventor: EXNER JAMES WALTER
IPC: H04B7/26
Filed: 1996-01-16
Abstract: A cellular modem pool provides call progress information to a calling party during call setup. In particular, the cellular modem pool includes a coupling means, which communicates any signals between the cellular-side of the cellular data connection and the PSTN-side of the cellular data connection during call setup. This allows the calling party to hear the call progress on the called party side of the data call. In addition, the cellular modem pool monitors the signals for a data signal provided by the called party, e.g., a predefined answer tone. Once the answer tone is detected, the cellular modem pool opens the connection provided by the coupling means and processes therespective signals on the cellular-side and the PSTN-side of the cellular modem pool.
