Engineering Contradiction Analysis
1Quantity of substance
If the reservoir computer device increases short-term memory property, then it can store more past information, but nonlinear transformation performance deteriorates
Solution Approach 1:
The patent implements dynamic control of the sampling rate for converting analog signals to digital signals. The sampling rate is adjusted based on the current processing requirements and characteristics of the input signal, allowing the system to optimize between memory capacity and processing performance dynamically rather than using fixed parameters
Solution Approach 2:
The patent changes key operating parameters including the sampling rate of the analog-to-digital converter and the weighting factors in the reservoir computing process. By adjusting these parameters adaptively, the system can shift between prioritizing memory storage and prioritizing nonlinear transformation accuracy depending on the task requirements
2Measurement precision
If the reservoir computer device processes more time-series data, then it improves estimation accuracy, but computational complexity increases
Solution Approach 1:
The patent extracts and processes only the most relevant portions of time-series data by controlling the sampling rate dynamically. Instead of processing all available data uniformly, the system selectively samples and processes data points that are most critical for accurate estimation, reducing unnecessary computational load while maintaining accuracy
Solution Approach 2:
The patent applies partial processing by using adaptive sampling rates that process more data when needed for accuracy and less data when sufficient information is already available. This prevents excessive processing that would increase complexity without providing additional benefit

AI summary
A signal processor includes an input unit, an analog-digital converter, and a reservoir unit. The input unit receives an input of a first analog signal. The analog-digital converter converts the first analog signal to a first digital signal. The reservoir unit receives an input of at least a part of the first digital signal. The reservoir unit determines a rule of a timing at which a control signal for extracting a part of the first analog signal or the first digital signal is output.
