Dynamic Sensor Sensitivity Adjustment via Multi-Loop Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems with multi-output sensors cannot dynamically adjust sensitivity based on environmental conditions or system status, requiring manual reprogramming to change sensitivity levels.
Innovation Solution
A method that allows a control panel to dynamically select and respond to different sensitivity levels of multi-output sensors based on preset criteria, such as system status, environmental conditions, or specific zones, using a multi-loop transmitter and programmable loop numbers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control panel is programmed to respond to only one loop number from a multi-output sensor, then the sensitivity level is fixed and stable, but the system cannot dynamically adjust sensitivity based on environmental conditions or system status
Solution Approach 1:
The system dynamically selects which loop number to respond to based on real-time conditions. The control panel evaluates selection criteria (such as system status, environmental conditions, or zone-specific parameters) and automatically switches between different sensitivity levels (loop numbers) without requiring manual reprogramming. This makes the sensitivity adaptive while maintaining stable operation within each selected level.
Solution Approach 2:
The invention changes the operational parameter (loop number/sensitivity level) based on predefined selection criteria. Instead of fixing the loop number during installation, the system monitors conditions and switches between loop numbers (e.g., from loop 1 to loop 2) when criteria are met, enabling dynamic parameter adjustment while maintaining reliability through criterion-based selection.
2Adaptability or versatility
If the installer manually reprograms the apparatus to change sensitivity, then the sensitivity can be adjusted to different levels, but the process requires time-consuming manual intervention and cannot respond to changing conditions in real-time
Solution Approach 1:
The control panel automatically performs the sensitivity adjustment function that previously required manual installer intervention. The system monitors selection criteria and autonomously determines which loop number to respond to, eliminating the need for the installer to physically reprogram the device. This self-service capability enables real-time adaptation without time loss.
Solution Approach 2:
The system continuously monitors selection criteria (such as system status, environmental conditions, or sensor readings) and uses this feedback to automatically adjust the sensitivity level. When criteria change, the control panel receives feedback about the new conditions and switches to the appropriate loop number, creating a closed-loop system that adapts in real-time without manual input.
3Reliability
If the control panel responds to all loops from a multi-loop transmitter, then all sensitivity levels are monitored, but the system lacks precision in selecting the appropriate sensitivity level based on specific conditions
Solution Approach 1:
The control panel extracts and responds to only the relevant loop number based on evaluated selection criteria, rather than treating all loops equally. The system monitors all loops for information but selectively responds to the specific loop that matches current conditions, extracting the precise sensitivity level needed while ignoring others. This maintains comprehensive monitoring capability while achieving precise selection.

AI summary
A method for dynamically changing a control panel response to a transmission from one or more multi-output sensors. The transmission includes a state of a plurality of sensitivity levels for each multi-output sensor indicating multiple outputs. The method comprising the steps of receiving a transmission from the multi-output sensor, determining a source of the transmission, determining a state of each of the sensitivity levels determining if at least one selection criterion is set for selecting one of the plurality of sensitivity levels included in the transmission based upon the determined source. One of the sensitivity levels is selected based upon the determination and an alarm is generated based upon said selected sensitivity level. If more than one selection criterion is set, a priority for the selection criterion is determined.
