Event-Grouped Sensor Array Output for Lower-Power Signal Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sensor systems with multiple elements, uneven data generation due to usage and environmental conditions leads to inefficient signal processing, causing unnecessary power consumption as the system searches all elements for data.
Innovation Solution
A data output device with an event array and event identifiers that classify sensing elements into groups, allowing only relevant elements to transmit event signals, reducing unnecessary data processing and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If all sensing elements are searched for data processing, then complete data coverage is achieved, but power consumption increases and processing efficiency decreases
Solution Approach 1:
The patent divides the sensing element array into multiple groups, with each group processed by a dedicated event identifier. This segmentation allows the system to process only relevant groups containing events, avoiding unnecessary processing of entire arrays and reducing power consumption while maintaining processing efficiency for active regions.
Solution Approach 2:
Instead of processing all sensing elements uniformly, the system applies partial action by identifying and processing only those elements that have detected events. The event identifier activates selectively based on event detection, performing actions only where needed rather than across the entire sensing array, thus reducing energy waste.
2Loss of time
If all sensing elements are processed uniformly, then data completeness is maintained, but processing time increases due to unnecessary searches
Solution Approach 1:
The system performs preliminary classification of sensing elements into groups before event processing. Event identifiers are pre-configured to recognize and process only their assigned groups, allowing rapid identification and processing of relevant data without searching entire arrays, thus reducing processing time while maintaining data completeness through systematic group coverage.
Solution Approach 2:
The event identifier acts as an intermediary between the sensing element array and the output interface. It receives signals from multiple sensing elements, identifies events within its assigned group, and transmits only relevant event information to the output, filtering out unnecessary data and reducing processing time while preserving complete event information.
3Device complexity
If event identifiers are assigned to individual sensing elements, then precise event location is achieved, but device complexity increases
Solution Approach 1:
The patent merges multiple sensing elements into groups, with each group handled by a single event identifier. This combining approach reduces the total number of event identifiers needed compared to individual element assignment, lowering device complexity while maintaining precise event location capability through group-based addressing and coordinated output interfaces.
