Abstract

A method and device for automatically metering, invoicing, and crediting the user of an apparatus located at a remote location. The method provides an authorization code to the apparatus issued by the owner and which enables the apparatus for a predetermined time period. At least one operation parameter is determined with respect to the use of the apparatus during the predetermined time period and an invoice is provided at the apparatus location. The invoice indicates the operation parameter and further indicates a fee based on the operation parameter. The device comprises a central processing unit for reception of the authorization code and a code verification system. The code verification system authorizes usage of the apparatus for a predetermined time period. The central processing unit determines at least one operation parameter during the predetermined time period and provides an invoice to the user.

Claims

1. A method for automatically invoicing and crediting a user for the use of an apparatus form a predetermined location, comprising the steps of:

a. providing an apparatus at a remote location for performing a predetermined function, said apparatus having a printer;

b. providing an authorization code to the apparatus at the remote location, said authorization code enabling operation of the apparatus for a predetermined time period;

c. automatically determining at least one operation parameter based on the use of the apparatus during said predetermined time period, via a processor having storage;

d. calculating a fee based on said operation parameter subsequent to said predetermined time period via said processor;

e. communicating said fee to said printer via said processor through communication device; and

f. providing an invoice at the remote apparatus location utilizing said printer, said invoice indicating said fee.

2. The method of claim 1, wherein said authorization code is provided to the remote apparatus location via a telephone link.

3. The method of claim 1, wherein said steps are cyclical and repeatable, and wherein a repeated provision of said authorization code to the apparatus clears previous said invoice fee.

4. The method of claim 1, wherein said steps are cyclical and repeatable, and wherein a repeated provision of said authorization code to the apparatus retains previous said invoice fee.

5. The method of claim 3, wherein provision of said authorization code to the apparatus is repeated subsequent to payment of said invoice.

6. The method of claim 4, wherein provision of said authorization code to the apparatus is repeated subsequent to payment on said invoice.

7. The method of claim 1, wherein said authorization code is verified at the remote apparatus location prior to said enabling.

8. The method of claim 7, wherein said verification is accomplished by utilizing an encryption scheme.

9. The method of claim 8, wherein said encryption scheme is a public key code.

10. The method of claim 1, wherein said predetermined time period is a common business invoicing period.

11. The method of claim 1, wherein said at least one operation parameter is the total operating time for the apparatus.

12. The method of claim 1, wherein the apparatus is useable in discreet operation cycles and wherein said at least one operation parameter is the total number of operations performed.

13. The method of claim 1, wherein the apparatus is useable for a plurality of types of operations and wherein said at least one operation parameter is the type of operations performed.

14. The method of claim 1, wherein the apparatus is useable in discreet operation cycles and wherein said at least one operation parameter is the average time for each operation.

15. The method of automatically invoicing the user of a medical apparatus which is usable in discreet operation cycles having a central processing unit and a printer, and crediting the user from a distant location, comprising the cyclical and repeatable steps of:

a. providing an authorization code to the apparatus from the distant location;

b. verifying, said authorization code at the apparatus location, said verifying enabling the apparatus for operation;

c. delineating a time period during which the apparatus is used;

d. compiling a number of discreet operation cycles performed by the apparatus during said time period, via a processor having non-volatile storage and permanent storage;

e. delineating a unit price for each operation cycle and entering said unit price in said permanent storage;

f. calculating, via said processor, a fee for apparatus usage during said time period based on said unit price and said number of operation cycles performed;

g. formatting an invoice indicating said fee, via said process;

h. communicating said invoice format to the apparatus central processing unit via a communication device; and

i. providing said invoice, via the apparatus printer, whereby said authorization code is provided subsequent to payment on said invoice.

16. An automatic metering and invoicing system for use with an apparatus, the apparatus having input means and a printer, and which is usable in discreet operation cycles, comprising:

a. means to receive an authorization code;

b. means to verify said authorization code, said verification means being communicating connected to said reception means, said verifying means authorizing usage of the apparatus for a predetermined time period;

c. non-volatile storage means, communicatively connected to the apparatus, for determining the number of operation cycles during said predetermined time period; and

d. means, communicatively connected to said non-volatile storage means and to the apparatus printer, to provide an invoice indicating a fee based on said number of operation cycles executed, via the apparatus printer, said means to provide an invoice including a system central processor having program logic means, and permanent storage means for holding a unit price for each operation cycle, said program logic means transmitting said invoice to the apparatus printer via communication device.

17. The automatic metering and invoicing system of claim 16, wherein said means to receive an authorization code comprises a serial link, and a system central processing unit, said central processing unit being communicatively connected to said serial link and to the input means of the apparatus.

18. The automatic metering and invoicing system of claim 16, wherein said verification means is a public key code and an interconnected system central processing unit.

19. The automatic metering and invoicing system of claim 16, wherein said determination means comprises storage and an interconnected system central processing unit having programmed logic means.

20. The automatic metering and invoicing system of claim 16, wherein said means to provide an invoice comprises an interconnected storage, serial link, and a system central processing unit having programmed logic means communicatively connected to the printer of the apparatus.

21. The automatic metering and invoicing system of claim 16, wherein the apparatus performs a medical procedure and comprises a CPU, a monitor, and a printer for generating data relating to the medical procedure.
