...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.

| 7597356 | Airbag cushions with gas deflectors and optional venting for out-of-position conditions An airbag cushion is disclosed for use in automotive protective systems. The airbag cushion includes at least one gas deflector which directs gas to a closeable vent to allow gas to be vented out of the cushion when an obstruction is encountered. ... | 10/06/2009 |
| 7240562 | Method for modeling material constitutive behavior In modeling material constitutive behavior, a methodology determines tool-chip friction and a position of a stagnation point on a cutting tool. The methodology includes measuring a ratio of cutting force to thrust force and measuring a chip thickness, hch... | 07/10/2007 |
| 7164662 | Network delay identification method and apparatus Network delay is determined in order to synchronize a clock in a mobile station with a reference clock. Tone are generated that represent a sequence of bits in a synchronization flag. The tones are sampled beginning at a selected sample start time. The sampled tones... | 01/16/2007 |
| 6765222 | Detection of motive force applied to transport box mounted on a fims system A motive force detection system prevents an overpowering of the movement of a transport box-carrying slidable tray of a FIMS system past a reference location upon detection of improper mating of the transport box to the FIMS system port plate or an obstruction to th... | 07/20/2004 |
| 6624750 | Wireless home fire and security alarm system A wireless alarm system (10) employs two-way transceivers (32, 60) in a network of smoke detectors (16), a base station (12), and other sensors.
