Sensor Event Consolidation via Profile Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Premises management systems face issues with multiple sensors detecting a single event as separate occurrences, leading to unnecessary alerts, and vice versa, such as a bus triggering a motion sensor when it shouldn't.
Innovation Solution
A method and system that consolidate events across sensors by comparing captured sensor data to stored event profiles, matching event sequences to determine if they represent a single event, thereby sending a single notice to a user device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors are deployed to detect events throughout a premises, then event detection coverage is improved, but false duplicate alerts increase
Solution Approach 1:
The patent merges data from multiple sensors by comparing sensor data against event profiles that define sequences of conditions. When sensor events match an event profile sequence, they are consolidated into a single alert notice, eliminating duplicate alerts while maintaining comprehensive event detection coverage across multiple sensors.
Solution Approach 2:
The system uses feedback by comparing sensor data against stored event profiles and adjusting alert generation based on matches. The event profile matching process provides feedback on whether sensor readings represent new events or duplicate detections, enabling the system to suppress false duplicate alerts while maintaining reliable event detection.
2Measurement precision
If sensors are made more sensitive to detect events, then detection accuracy is improved, but false positive detections increase
Solution Approach 1:
The patent applies preliminary action by pre-defining event profiles that contain sequences of conditions representing legitimate events. Before generating an alert, the system checks sensor data against these pre-established profiles, allowing it to distinguish true events from false positives even when sensors are highly sensitive.
Solution Approach 2:
The system uses feedback by comparing sensor readings against stored event profile sequences. This feedback mechanism allows the system to confirm whether sensitive sensor detections represent actual events or false positives, maintaining high detection accuracy while reducing false alarm rates.
3Loss of information
If multiple alert notices are sent for each sensor detection, then event reporting completeness is improved, but user alert fatigue increases
Solution Approach 1:
The patent merges multiple sensor detections that match an event profile sequence into a single consolidated alert notice. This approach maintains complete event reporting by capturing all sensor inputs while eliminating duplicate alerts, thereby preventing user alert fatigue.
4Measurement precision
If event profiles include multiple conditions for matching, then event identification accuracy is improved, but processing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-defining event profiles with multiple conditions and sequences before runtime. This allows the system to perform complex multi-condition matching without real-time processing complexity, as the evaluation logic is established in advance and can be efficiently executed when sensor data arrives.

AI summary
A method may receive, in response to a first event, a first sensor data from a first sensor, and receive, in response to the first event, a second sensor data from a second sensor. The method may select, from among a plurality of event profiles, a first event profile. The first event profile may comprise a first condition matching the first sensor data, a second condition matching the second sensor data, and a plurality of conditions which, when met, indicate the occurrence of the first event. Conditions may include a sensor data, a time period, a user data, a sequence of conditions, or a combination of such data. The first event profile may comprise a first event notice to be provided in response to the occurrence of the first event. The method may provide the first event notice to a recipient indicated by the event profile.
