Abstract

An arrangement for optimizing a servo controller power required in the operation of two-dimensional flexure (Microelectronic Memory Storage) MEMS devices.

1 . An arrangement for optimizing servo controlled power in the operation of two-dimensional flexure microelectronic memory storage devices, comprising:
 a stationary base member;   a movable scanner platform having memory storage media located on an upper surface of said scanner platform;   flexural supports for said scanner platform being positioned on said stationary base member facilitating displacement of said movable scanner platform in x- and y-directions relative to said stationary base member;   actuators connected to said movable scanner platform and being responsive to the operation of servo controllers for imparting said x- and y-directional displacements thereto, including x- and y-position sensors for determining the extent of displacement of said scanning platform; and   a scanning structure movable along x- and y-coordinates about the surface of said scanner platform containing said microelectronic memory storage media to the vicinity of a target track within a period of time minimizing power output required for said servo controllers.   
     
     
         2 . An arrangement as claimed in  claim 1 , wherein said servo controllers reduce power requirements for said actuators by a zonal data storage array on said movable scanner platform. 
     
     
         3 . An arrangement as claimed in  claim 2 , wherein said zonal data storage array on said scanner platform comprises clustering of frequently employed data about a home position of said scanning structure. 
     
     
         4 . An arrangement as claimed in  claim 3 , wherein said servo controllers actuate said actuators for x- and y-displacements so as to synchronize random seeks in the microelectronic memory storage devices so as to necessitate minimum power requirements for random data seeks on said scanner platform surface. 
     
     
         5 . An arrangement as claimed in  claim 3 , wherein said data is arranged on said scanner platform so as to propagate outwardly in predetermined zones and inwardly towards said home position in further zones. 
     
     
         6 . An arrangement as claimed in  claim 1 , wherein said scanning structure comprises an electronic read and write device displaceable about the data-containing surface of said movable scanner platform. 
     
     
         7 . An arrangement as claimed in  claim 1 , wherein said scanning structure comprises a scanner probe positioned at the peripheral edge of said movable scanner platform. 
     
     
         8 . An arrangement as claimed in  claim 7 , wherein said scanning structure comprises prisms forming said scanner probe on opposite sides of the scanner platform edge. 
     
     
         9 . An arrangement as claimed in  claim 1 , wherein each said x- and y-servo controller comprises, respectively, operative system velocity estimators, velocity controllers and position controllers in operative interconnections with said x- and y-actuators and sensor electronics determinative of the displacement of said scanning structure on the surface of said scanner platform. 
     
     
         10 . An arrangement as claimed in  claim 1 , wherein said data is provided on the surface of said scanner platform as an array of surface indentations or pits. 
     
     
         11 . An arrangement as claimed in  claim 10 , wherein said indentations or pits are formed in a polymer layer located on the upper surface of said scanner platform; and said scanning structure includes a resistive heater probe for contacting said indentations and pits to derive data therefrom.
