Abstract
A magnetically assisted coupling comprises at least two shaft segments. Each shaft segment has opposed ends and a hollow core. Adjacent segment ends are configured in a probe/socket configuration such that one segment end is configured to receive the adjacent segment end. Magnets of opposite polarity are mounted within said hollow core of adjacent segment ends, such that the magnet in the socket is positioned at a bottom of the socket, while the magnet in the probe defines a probe end. When adjacent segment ends are brought into close proximity the magnets attract each other and draw the probe end into the socket until the magnets are in contact.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
