Remote Intrusion Detector Signal Pattern Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for adjusting the signal broadcast pattern of intrusion detectors require manual actuation, which is time-consuming and inconsistent due to the need for multiple adjustments and is impractical for detectors in hard-to-reach locations.
Innovation Solution
A system that includes a microwave sensor, a digital potentiometer, a communication module, and a processor with control software, allowing for remote adjustment of the signal broadcast pattern via a mobile device or control panel, enabling automatic adjustment of sensitivity and amplitude to match desired broadcast areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual adjustment mechanism is used, then device complexity is reduced, but adjustment time and consistency deteriorate
Solution Approach 1:
The patent replaces the manual mechanical adjustment mechanism with an automated electronic system. A microprocessor-controlled digital potentiometer adjusts the circuit gain electronically based on environmental sensor readings, eliminating the need for manual mechanical intervention while reducing adjustment time and improving consistency.
Solution Approach 2:
The intrusion detector performs self-adjustment by automatically sensing environmental conditions and modifying its own signal broadcast pattern. The system uses internal environmental sensors to detect changes in temperature, humidity, and other factors, then autonomously adjusts the circuit gain to maintain optimal detection sensitivity without requiring external manual intervention.
2Device complexity
If manual adjustment mechanism is used, then device complexity is reduced, but adjustment consistency deteriorates
Solution Approach 1:
The patent replaces the manual mechanical adjustment mechanism with an automated electronic system. A microprocessor-controlled digital potentiometer adjusts the circuit gain electronically based on environmental sensor readings, eliminating the need for manual mechanical intervention while reducing adjustment time and improving consistency.
Solution Approach 2:
The system continuously monitors environmental conditions using internal sensors and uses this feedback to automatically adjust the signal broadcast pattern. The environmental sensors provide real-time data about temperature, humidity, and other factors that affect detection sensitivity, enabling the system to maintain consistent and reliable adjustment based on actual environmental conditions.
3Ease of operation
If remote adjustment is implemented, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent introduces a communication module as an intermediary between the user and the intrusion detector's adjustment mechanism. This module enables remote adjustment of the signal broadcast pattern through wireless communication, allowing users to modify detection sensitivity without physically accessing the device, while the added complexity is managed through integrated circuit design.

AI summary
Systems and methods for adjusting a broadcast pattern of an intrusion detector are provided. Such systems and methods can include a microwave sensor of the intrusion detector broadcasting a detection signal into a secured area in the broadcast pattern, a communication module of the intrusion detector wirelessly receiving a signal adjustment command from a remote device, and a processor and executable control software of the intrusion detector parsing the signal adjustment command and instructing a signal adjuster of the intrusion detector to adjust a sensitivity of the microwave sensor or an amplitude of the detection signal to alter the broadcast area of the broadcast pattern based on information contained in the adjustment command.
