A ferroelectric memory comprises a plurality of memory cells and circuitry to sense data thereof. The elevator car is suspended on the hoisting ropes by means of at least one diverting pulley from whose rim the hoisting ropes go upwards from both sides and at least one diverting pulley from whose rim the hoisting ropes go downwards from both sides of the diverting pulley. Regulation can be accomplished through networked femtocell access points and distributed antenna systems. The systems, devices, and methods of the present invention can allow for effective use of samples by improved sample preparation and analysis.
