NFC Memory Layout for Direct ASCII Message Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Near-field communication devices face inefficiencies in transmitting messages due to the need for conversion from binary to ASCII format, which increases memory space requirements and introduces delays and power consumption during transmission.
Innovation Solution
Storing messages in a near-field communication device with a static portion in a free access area and a dynamic portion in a restricted access area, both in ASCII format, allowing for direct transmission without the need for conversion, with the static portion containing a website address and the dynamic portion generated by a counter or logic circuit, optimizing memory usage and eliminating the conversion step.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If messages are stored in binary format and converted to ASCII for transmission, then transmission compatibility is improved, but memory space requirements increase and transmission time increases
Solution Approach 1:
The patent applies preliminary action by pre-storing messages in ASCII format within the memory before transmission is needed. This eliminates the need for conversion during transmission, as the messages are already in the required format. The static portion contains the base message in ASCII, while the dynamic portion can be appended in ASCII format, avoiding binary-to-ASCII conversion delays and reducing memory space requirements compared to storing only in binary format.
2Adaptability or versatility
If messages are converted from binary to ASCII format during transmission, then transmission compatibility is improved, but transmission time increases
Solution Approach 1:
The patent applies preliminary action by pre-converting and storing messages in ASCII format within the memory before transmission is needed. This eliminates the need for conversion during transmission, as the messages are already in the required format. The static portion contains the base message in ASCII, while the dynamic portion can be appended in ASCII format, avoiding binary-to-ASCII conversion delays.
3Adaptability or versatility
If messages are converted from binary to ASCII format during transmission, then transmission compatibility is improved, but power consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-converting and storing messages in ASCII format within the memory before transmission is needed. This eliminates the need for conversion during transmission, as the messages are already in the required format. By performing the conversion beforehand rather than during transmission, the system reduces real-time power consumption associated with binary-to-ASCII conversion operations.
4Reliability
If the dynamic portion is stored in a restricted access area, then security is improved, but access complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the memory into distinct areas: a static portion for storing the base message in ASCII format and a dynamic portion for storing variable data. The dynamic portion is placed in a restricted access area that can be selectively accessed during transmission. This segmentation allows the system to maintain security by restricting access to sensitive dynamic data while simplifying the transmission process, as only the necessary portions need to be accessed based on transmission requirements.

AI summary
A near-field communication device operates to transmit data by near-field communications techniques to another device. The near-field communication device includes a memory that stores a message to be transmitted in an ASCII format. The message is retrieved from the memory and transmitted using the near-field communications techniques in an ASCII format.
