Paperless recorder for tamper-proof recording of product process information
First Claim
1. A electronic paperless recorder for recording and retrieving data and other information related to a product process, the recorder comprising:
- a paperless information storage medium;
a processor configured to receive, store and retrieve data and other information related to the process, further configured to record the data and other information on the paperless data storage medium, and further configured to record an electronic signature on the paperless data storage medium in association with at least a portion of the data and other information.

Abstract
A method for paperless recording in a production or measuring process is provided. The method includes the steps of receiving data from a continuous or discontinuous process, e.g., for a milk product, recording the data on a paperless data storage medium, and recording an electronic signature on the paperless data storage medium in association with at least a portion of the data. An apparatus for tamper-proof/sealable paperless recording in a process is also provided. The apparatus includes a paperless data storage medium and a processor. The processor is configured to receive data from a continuous or discontinuous process, is further configured to record the data on the paperless data storage medium, and is further configured to record an electronic signature on the paperless data storage medium in association with at least a portion of the data.

10. A recorder system for recording and retrieving information related to a product process, the recorder comprising:
-
an electronic central processing unit CPU; and
main memory and replaceable flash memory accessible to the CPU for electronically storing information related to the process;
analog input and output circuits for communicating between the CPU and various process sensors information representing measured values of parameters of the process;
digital input and output circuits for communicating between the CPU and various process sensors information representing measured values of process parameters and the logical state of process conditions;
a keyboard and function keys for use by the user to communicate information to the CPU;
a graphic display communicating with the CPU for displaying information to and requesting information from the user;
communication interface circuits accessible to the CPU and main memory;
a casing enclosing the CPU, main memory, flash memory, analog input and output circuits, and digital input and output circuits, the casing sealed by a seal against undetected entry to the casing after the seal is applied;
a flash memory card drive;
a sealable cover covering the flash memory card drive, said cover preventing unauthorized removal of a flash memory card; and
a digital computer communicating through the serial communication interface circuits to the CPU and main memory, the computer having software accessible thereto adapted to search and retrieve process information from the main memory, and to present process information to the user, the main memory being accessible to the computer for purposes of retrieving process information from the main memory and communicating said retrieved process information to the computer, the main memory being inaccessible to receive process information from the computer.
