METHOD FOR OPERATING A SAFETY-CRITICAL COMPUTER SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18439935 titled 'METHOD FOR OPERATING A SAFETY-CRITICAL COMPUTER SYSTEM
Simplified Explanation: The patent application describes a method for operating a safety-critical computer system with redundant channels for processing a calculation task. Each channel independently generates results, which are monitored for health status. A decider downstream of each channel enables or blocks output based on the health status, ensuring only one channel is enabled for output at a time.
Key Features and Innovation:
- Safety-critical computer system with redundant processing channels
- Independent generation of results by each channel
- Monitoring of health status for each channel
- Decider for enabling or blocking output based on health status
- Use of a token to block output from all but one channel
Potential Applications: This technology could be applied in industries where safety-critical systems are essential, such as aerospace, automotive, and medical devices.
Problems Solved: This technology addresses the need for reliable and fail-safe operation in safety-critical computer systems by ensuring that only one channel is enabled for output at a time.
Benefits:
- Enhanced safety and reliability in critical systems
- Redundancy to prevent system failures
- Efficient monitoring of channel health status
- Clear decision-making process for output enablement
Commercial Applications: The technology could be used in the development of advanced safety systems for vehicles, aircraft, and medical equipment, providing a competitive edge in industries where reliability is paramount.
Prior Art: Readers interested in prior art related to this technology may explore patents and research papers on redundant systems in safety-critical applications.
Frequently Updated Research: Researchers may find updated studies on redundant systems, safety-critical computing, and decision-making processes in critical applications relevant to this technology.
Questions about Safety-Critical Computer Systems: 1. How does the use of redundant channels enhance the safety of a computer system? 2. What are the key considerations when implementing a decider for enabling or blocking output in a safety-critical system?
Original Abstract Submitted
A method for operating a safety-critical computer system which has at least two redundant channels for processing a calculation task. The channels generate results for the calculation task independently of one another. The health status of each individual channel is monitored separately. A separate decider for enabling or blocking output of the results is connected downstream of each channel. Depending on the health status of the channels, at most one of these channels is enabled for output of the results. It is ensured with the aid of a token that output of the results is blocked for all other channels.
