Did You Know...
...that while attempting to develop a super strong glue, 3M employee Spencer Silver accidentally developed a glue that was so weak it would barely hold two pieces of paper together? However, his colleague Art Fry needed the glue. Fry sang with his church choir and marked the pages of his hymnal with small scraps of paper that often fell out. He used Silver's glue to hold the papers in place. Today we call this invention Post-it Notes.

It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractA peripheral platform, such as an Intelligent Peripheral (IP), is a network subsystem for use in the Advanced Intelligent Network (AIN). The IP or similar platform will assume some functions presently performed by the Integrated Service Control Point (ISCP) and central office switches. Among its functional capabilities will be voice announcement and digit collection. The more advanced version, the IP, also offers speech recognition capabilities and an array of other enhanced call processing features, such as voice or facsimile messaging. The peripheral platform or IP will be a separate network component that will communicate with the ISCP, which controls the AIN, through a data communication network that in the preferred embodiments is distinct from the telephone company switching offices, trunk networks and any associated interoffice signalling network.Other References
