Abstract
A micro-mover system includes an information storage unit having multiple pairs of parallel plates closely spaced from each other to enable the exchange of information. A micro electromechanical system (MEMS) motor is associated with each pair of plates to move one of each pair of parallel plates in a plane parallel to the other plate in each pair to facilitate the exchange of information between each pair of plates. One pair of parallel plates is oriented to move in a direction opposite to another pair of parallel plates. Control circuitry is associated with each MEMS motors to coordinate the plate pair movements associated with that motor, so that the motion of one plate in one set of parallel plates occurs at the same time and in a direction opposite to the movement of the one plate of another set of parallel plates, thereby canceling a substantial level of total momentum arising from movement within the micro-mover system. A method of storing information in a memory storage system utilizes a plurality of pairs of plates, where each pair of plates is associated with a micro-mover for moving at least one plate relative to the other plate in each pair of plates. Plates in each of adjacent plate pairs move in directions opposite to each other along a common axis for the same distance and time, so that the momenta of the plate pairs are approximately equal and cancel each other.

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.
