Abstract
Abstract A charge calculator is provided in which the net time of use of a facility is calculated. Provision is made for dividing the net time by a selectable time unit to obtain a quotient. A charge is determined in accordance with the quotient and the charge is multiplied by the quotient to obtain a result. The circuit for determining the charge according to the quotient may be programmable and may be provided in the form of a diode matrix.
