RFID Control Integration in MO:DCA Print Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RFID technologies require separate data streams and cumbersome processes for creating and controlling RFID tags, making it inefficient for tracking multiple articles with unique data, especially in mercantile and security applications where flexibility is needed.
Innovation Solution
The integration of 'smart objects' within the print data stream using the MO:DCA architecture allows for the inclusion of RFID control and data objects without interfering with printer operations, enabling direct control and data exchange between the host computer and RFID devices embedded in the printing medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate data streams are used for printer control and RFID control, then printer operations and RFID operations can be controlled independently, but the system complexity increases and the process becomes cumbersome
Solution Approach 1:
The patent combines printer control data and RFID control data into a single integrated data stream. The RFID control commands are embedded within the printer data stream structure, allowing both printer and RFID device to be controlled through one unified communication channel rather than requiring separate independent data streams
Solution Approach 2:
The data stream structure is designed to serve multiple functions simultaneously - it controls both the printer operations and the RFID reading/writing operations. The same data stream that carries print data also contains embedded commands for RFID tag manipulation, making the system more versatile without requiring additional separate control mechanisms
2Manufacturing precision
If separate control streams are used for printer and RFID devices, then each device can be controlled precisely, but the ease of operation decreases
Solution Approach 1:
The patent merges printer control and RFID control into a single data stream structure. Commands for both devices are interleaved or embedded within the same data flow, allowing users to control both devices through a single interface without managing multiple separate control streams, thereby improving ease of operation while maintaining control precision
3Productivity
If RFID control is integrated into the print data stream, then the process is streamlined and flexibility is enhanced, but the difficulty of detecting and measuring control signals increases
Solution Approach 1:
The patent segments the integrated data stream into distinct identifiable command structures. RFID control commands are formatted with specific delimiters and structure that differentiate them from printer control commands, allowing the receiving device to easily parse and identify RFID-specific signals within the combined data stream through pattern recognition and structured formatting
Data Source
AI summary
A method of communicating non-native print objects in MO:DCA Architecture for controlling and operating RFID writer or reader devices without requiring separate control data streams or systems to be implemented at the host computer. Data references and command identifiers are placed by application program means at the host computer into the page description data so that RFID information can be retrieved and downloaded to the printer and RFID apparatus when the print data is being processed in the print server or main processor of the printer without interfering with normal operation of the printer itself.
