In another embodiment, the spring is formed into a coil or helix with a wire wrapped around at least a portion of the helical spring. In one form of this embodiment, the spring has a plurality of turns and the wire is wrapped around at least two of the turns. In another form of this embodiment, the spring has a plurality of turns and the wire is wrapped around all of the turns. An interposer connector is also provided having a frame including a top surface and a bottom surface and a plurality of apertures arranged in a pattern and opening onto the top and bottom surfaces of the frame. A plurality of springs are provided with each spring having a conductor wrapped around at least a portion of the spring where the conductor has a greater electrical conductivity than the spring.

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.
