Abstract
An integrated gimbal suspension includes a flexure with an integrated, built-in gimbal, and includes a limiter structure that constrains motions of the gimbal in multi-degrees of freedom. The limiter structure includes one or more tab-shaped limiters and corresponding stops integrally formed into the gimbal assembly at strategic locations, which interact to provide the desired constraints to the motions of the flexure gimbal to prevent permanent damage from over-straining the gimbal or flexure beyond its designed range. The limiters may be pre-formed tab-shaped structures that are bent from the plane of the flexure. As the gimbal moves from its nominal position, one or more limiters engage the stops before such motion reaches the limit of the designed range of motion of the gimbal.

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.
