Claim 1

A COUNTER BANK COMPRISING: (A) A PLURALITY OF BISTABLE MAGNETIC THIN FILM ELEMENTS OF THE SINGLE PREFERRED MAGNETIC AXIS TYPE WHICH ARE ARRANGED IN A NUMBER J OF COLUMNS EACH WITH A NUMBER N OF ELEMENTS; (B) A NUMBER J OF WORD WINDINGS WITH EACH JTH WORD WINDING (WHERE 1$J$J) BEING INDUCTIVELY COUPLED WITH EVERY ELEMENT OF THE RESPECTIVE JTH COLUMN SUCH THAT CURRENT FLOW THEREIN APPLIES A FIRST MAGNETIC FIELD SUBSTANTIALLY TRANSVERSE TO THE PREFERRED MAGNETIC AXIS OF EACH COUPLED COLUMN ELEMENT; (C) A NUMBER N OF DRIVE WINDINGS WITH EACH NTH DRIVE WINDING (WHERE 1$N$N) BEING INDUCTIVELY COUPLED WITH THE RESPECTIVE NTH ELEMENT IN EACH JTH COLUMN SUCH THAT CURRENT FLOW THEREIN APPLIES A SECOND MAGNETIC FIELD SUBSTANTIALLY PARALLEL TO THE PREFERRED MAGNETIC AXIS OF EACH COUPLED NTH ELEMENT; (D) A NUMBER J OF SENSE WINDINGS, WITH EACH JTH SENSE WINDING BEING INDUCTIVELY COUPLED WITH EVERY ELEMENT IN THE RESPECTIVE JTH COLUMN SUCH THAT EITHER A FIRST POLARITY EMF OR A SECOND OPPOSITE POLARITY EMF IS RESPECTIVELY INDUCED THEREON BY A REVERSAL OF FLUX PARALLEL TO THE PREFERRED MAGNETIC AXIS IN ANY ONE OF ITS COLUMN COUPLED ELEMENTS FROM A FIRST POLARIZED STABLE DIRECTION TO A SECOND OPPOSITELY POLARIZED STABLE DIRECTION, OR FROM SAID SECOND STABLE DIRECTION TO SAID FIRST STABLE DIRECTION, RESPECTIVELY; (E) A NUMBER J OF CONTROL MEANS WITH EACH JTH CONTROL MEANS BEING CONNECTED TO THE RESPECTIVE JTH WORD WINDING AND SELECTIVELY ACTUABLE TO A FIRST STATE TO APPLY CURRENT TO GENERATE SAID FIRST MAGNETIC FIELD; (F) GENERATOR MEANS FOR APPLYING TO ALL OF SAID N DRIVE WINDINGS IN A PREDETERMINED NONOVERLAPPING SEQUENCE A LIKE PAIR OF TIME-SEPARATED CURRENT PULSES EACH PULSE OF DIFFERENT POLARITY AND EACH PULSE PRODUCING A SAID SECOND MAGNETIC FIELD OF DIFFERENT POLARITY WHICH HAS A MAGNITUDE SUFFICIENT ONLY IN THE PRESENCE OF A SAID FIRST MAGNETIC FIELD TO REVERSE OPPOSITELY POLARIZED FLUX IN ANY NTH ELEMENT COUPLED WITH THE RESPECTIVE NTH DRIVE WINDING; AND (G) A NUMBER J OF RESETTING MEANS WITH EACH JTH RESETTING MEANS BEING CONNECTED TO THE RESPECTIVE JTH SENSE WINDING FOR DEACTUATING THE RESPECTIVE JTH CONTROL MEANS TO A SECOND STATE IN RESPONSE TO ONLY THAT POLARITY EMF WHICH CAN BE INDUCED BY A REVERSAL OF ELEMENT FLUX CAUSED BY THE FIRST OF SAID PAIR OF DIFFERENT POLARITY CURRENT PULSES TO BE APPLIED BY SAID GENERATOR MEANS TO ANY NTH DRIVE WINDING.
