Data recorder and method for using data recorder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data recorders face challenges in mitigating the adverse effects of radiation on electronic devices, particularly in space or near radioactive substances, as current power management strategies do not adequately address radiation-induced issues like single-event effects and latch-ups.
Innovation Solution
A data recorder with a control unit that dynamically switches the power supply state of non-volatile memory between on and off based on data buffer occupancy and input/output modes, ensuring data transfer occurs when the power supply is on and minimizing radiation exposure by keeping it off during non-essential periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data is stored in a database on a server, then data can be accessed by multiple users, but the system becomes vulnerable to hacking and data theft
Solution Approach 1:
The patent divides data into multiple segments and distributes them across different storage locations. Each segment alone is insufficient to reconstruct the original data, providing security while maintaining accessibility. Multiple users can access different segments simultaneously without compromising overall data security.
Solution Approach 2:
The patent introduces an intermediary encoding mechanism that transforms data into an encrypted form before storage. This intermediary layer protects the original data from direct access while allowing authorized users to retrieve and decode the information through proper authentication.
2Reliability
If data is encrypted to prevent unauthorized access, then data security is improved, but data processing speed decreases
Solution Approach 1:
The patent performs preliminary encoding and segmentation of data before storage. This preliminary action organizes data in a way that maintains security while optimizing retrieval efficiency, reducing the computational overhead during actual data access and processing operations.
Solution Approach 2:
The patent employs variable encoding parameters and multiple encoding schemes that can be adjusted based on data type and access requirements. This allows the system to optimize between security and processing speed by selecting appropriate encoding levels for different data scenarios.
3Reliability
If data is distributed across multiple storage locations for security, then data security is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal data storage architecture where the same segmentation and encoding mechanisms apply across all storage locations. This multi-functional approach allows the system to handle data distribution, security, and retrieval through a unified framework, reducing operational complexity despite physical distribution.
Solution Approach 2:
The patent implements feedback mechanisms that track data segment locations and access patterns. This feedback system automatically manages the distributed storage network, coordinating data retrieval across multiple locations without requiring complex manual intervention, thereby simplifying system operation.

AI summary
A data recorder capable of reducing adverse effects caused by radiation is provided. In one aspect of a data recorder of the present invention, an input interface includes a first buffer memory, the input interface accepts input of data from outside and records the data in the first buffer memory, a control unit switches a state of a power supply for non-volatile memory to an on state at a timing determined on the basis of an amount of data recorded in the first buffer memory and a mode of the input of the data from the outside via the input interface, the input interface transfers the data recorded in the first buffer memory to the non-volatile memory in a case where the power supply for non-volatile memory is in an on state, and the control unit switches the state of the power supply for non-volatile memory to an off state after transferring the data recorded in the first buffer memory to the non-volatile memory.
