Distributed market based analog control of a system of actuators and sensors. The system is comprised of one or more producing units having an output responsive to a market price and one or more input units having an input responsive to a market price. Market price information is communicated through an information channel that is encoded as measurable changes in non-electrical partitionable physical properties. Such partitionable physical properties include pressure, thermal, chemical or acoustic properties.

The method according to claim 1 wherein the moving step includes positioning an emitter having an elongated radiation emitting outlet. 5. The method according to claim 4 wherein the moving step includes positioning an emitter having a fiber optic bundle. 6. The method according to claim 1 and further comprising sensing the amount of radiation received by a receiver, and adjusting intensity of the radiation emitted by the emitter to a level responsive to an amount of radiation received by the receiver. 7. The method according to claim 1 wherein the emitter includes a fiber optic bundle, wherein the passing step includes passing radiation through the fiber optic bundle. 8. A method comprising: moving at least one sheet generally along a sheet moving direction in a sheet path in an automated banking machine between an emitter and a receiver; wherein the at least one sheet has patterns of indicia thereon, wherein the indicia affect transmissivity of radiation through the at least one sheet, wherein the at least one sheet has a width in a direction generally transverse to the sheet moving wherein the emitter and the receiver are positioned on opposed sides of the sheet path, wherein the receiver is in supporting relation with a bin door overlying a document storage area in the automated banking machine, wherein the receiver is operative to receive radiation from the emitter, wherein the emitter and the receiver are generally aligned and extend a substantially equal elongated distance generally transversely to the sheet moving direction, and wherein the emitter and the receiver extend at least five percent of the width of the at least one sheet, passing radiation from the emitter through the at least one moving sheet generally transversely to the sheet moving direction; receiving with the receiver radiation passed through the at least one moving sheet; producing a signal with the receiver responsive to an amount of radiation passed through the at least one moving sheet that the receiver received from the emitter; comparing the produced signal to a threshold, wherein the threshold corresponds to overlapped sheets; determining whether the at least one sheet comprises overlapped sheets responsive to the comparison. 9. The method according to claim 8 wherein the emitter includes a fiber optic bundle, wherein the passing step includes passing radiation through the fiber optic bundle.
