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.AbstractAn adaptive, performance-optimizing communication system for communicating with an implanted medical device in which signals are transmitted and received in accordance with predetermined, interrelated operational parameters, such as transmission rate, transmitter power, and the like. Various aspects of system performance, including bit error rate in received signals, the strength of received signals, the signal-to-noise ratio of received signals, the presence of local RF noise and non-telemetry related RF signals, and the like, are dynamically monitored by the communication system, to determine whether predetermined system performance goals are being met. If it is determined that one or more system performance goals are not being met, one or more operational parameters may be automatically adjusted so that desired performance can be achieved. | InventorsAssigneeApplicationNo. 816223 filed on 03/12/1997US Classes:607/32, Communicating with pacer (e.g., telemetry)128/903, RADIO TELEMETRY607/31, Assurance of security, accuracy, or completion of programming procedure607/60Telemetry or communications circuitsField of Search607/60, Telemetry or communications circuits607/31, Assurance of security, accuracy, or completion of programming procedure607/32, Communicating with pacer (e.g., telemetry)128/903RADIO TELEMETRYExaminersPrimary: Kamm, William E.Assistant: Layno, Carl H.
