Abstract
A system and method for data entry by an operator uses data containing a first component and a second component derived therefrom, wherein the second component has error detection and correction abilities therein. The second component of the entered data is used to detect and correct error in the data entered for the first component. The first and second components are preferably characters (e.g., representing GPS position information) entered via a data entry device, while the second component preferably comprises Hamming code. The detection and correction can be performed after data entry and again after signal transmission.
Claims17
A system for data entry, the system comprising:
- means for manual operator entry of data containing a first component and a second component derived from the first component, wherein the second component includes error detection and correction abilities for the first component therefore;
- and
- means for receiving the entered data, deriving therefrom the second component, and using the second component to detect and correct error in the data received for the first component,
- wherein the means for manual entry includes a data entry device.
A method for data entry, comprising the steps of:
- entering, by an operator using a data entry device, of data containing a first component and a second component derived therefrom, wherein the second component has error detection and correction abilities therein;
- and
- deriving from the entered data the second component and using the second component to detect and correct error in the data entered for the first component.
A program storage device readable by a machine, tangibly embodying a program of instructions executable by said machine to perform a method for verifying proper manual data entry into said machine using a data entry device, said method comprising the steps of:
- receiving data containing a first component and a second component derived therefrom, wherein the second component has error detection and correction abilities contained therein;
- and
- determining from the received data the first component and the second component and using the second component to detect and correct error in the first component.
