Radio Tone Generation for Canine Deterrence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to prevent unwanted canine interactions during public-safety incidents, as police canines often mistakenly attack other officers at the scene, posing a risk to their safety.
Innovation Solution
A method and apparatus that utilize radios associated with the incident scene to generate a tone, specifically a 20-55 kHz tone, to deter or repel approaching canines, which are notified through a Computer-Aided Dispatch (CAD) system or local alerts from devices like collars or car doors, ensuring officers are protected from accidental apprehension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a canine is deployed to apprehend a suspect, then the canine can effectively pursue and capture the suspect, but the canine may mistakenly attack other public safety officers at the incident scene
Solution Approach 1:
The system applies preliminary anti-action by broadcasting a repelling tone to canines before they can mistakenly attack officers. The tone is transmitted on a dedicated frequency that canines hear but officers cannot, creating a preemptive deterrent that prevents mistaken attacks while allowing the canine to perform its apprehension function.
Solution Approach 2:
The repelling tone acts as an intermediary between the canine and the officers. It provides selective communication where the canine receives information (the repelling tone indicates presence of officers) without the officers needing to communicate directly with the canine, thus preventing mistaken attacks while maintaining operational effectiveness.
2Reliability
If all radios at the incident scene transmit continuously, then officer safety is maximized through constant tone emission, but radio battery life and system resources are depleted
Solution Approach 1:
The system implements periodic action by having radios transmit the repelling tone in cycles rather than continuously. The tone is broadcast periodically, which maintains effectiveness in deterring canines while significantly reducing battery consumption and preserving radio resources compared to continuous transmission.
Solution Approach 2:
The system uses self-service by leveraging existing radio infrastructure and communications already in use at the incident scene. The repelling tone is embedded within or transmitted alongside normal radio communications, allowing the system to protect officers without requiring separate dedicated transmission resources or additional battery-powered devices.
3Loss of information
If a repelling tone is transmitted on a frequency officers can hear, then officers can identify the source of the noise, but canines will not be deterred as they cannot hear that frequency
Solution Approach 1:
The system applies local quality by using different frequency characteristics for different audiences. The repelling tone is transmitted on a frequency spectrum that is audible to canines but inaudible or imperceptible to human officers, allowing each species to perceive the communication in its appropriate local frequency zone without interference.
Solution Approach 2:
The radio transmission system serves as an intermediary that converts officer commands into a frequency format canines can perceive. The system translates human-audible commands into ultrasonic or high-frequency tones that deter canines, acting as a mediator between human communication and canine perception without requiring direct human-canine auditory communication.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents accidental canine interactions by alerting and deterring canines from approaching public-safety officers, enhancing their safety during deployments by using a specific tone that is uncomfortable for canines and trained to avoid.
Implementation Method 1
The radios will then generate a tone to deter or repel any approaching canine
Data Source
AI summary
A method and apparatus for blocking unwanted canine interactions during a canine deployment at a public-safety incident scene is provided herein. During operation all radios associated with a public-safety incident scene will be provided a notification of canine deployment. The radios will then generate a tone to deter or repel any approaching canine.
