AI Technical Summary
There is a lack of a universal, two-sided, portable distance warning system that operates without a mobile network and can simultaneously enable both approach and targeted search, failing to protect individuals at risk from perpetrators who are monitored, leading to incidents such as attacks, harassment, and serious acts of violence.
A system of two or more electronic tags/trackers that detect proximity, provide real-time warnings, and ensure unambiguous pairing, with features like area monitoring, position and direction indication, and independent operation without reliance on mobile networks or smartphones, including battery safety and multiple tracker assignments.
The system effectively reduces attacks and harassment by providing reliable, network-independent warnings and search capabilities, ensuring high security and universal applicability, particularly in domestic violence cases.
Abstract
Description
Technical field:
[0001] The invention relates to an electronic monitoring, warning, and protection system used to prevent proximity or contact hazards. It is particularly suitable for: *State-ordered contact bans (e.g., in cases of domestic violence), *Personal protection *Child safety *Search and rescue operations *military units or special operations *Group leadership *Leisure and outdoor applications. Initial situation / Problem statement
[0002] There is a central problem with contact attempts or protective measures: The perpetrator (e.g. with an ankle monitor) is monitored - but the person at risk is not.
[0003] As a result, despite electronic ankle monitors, cases of: *attacks, *Harassment, *Reenactment, *serious acts of violence, including homicide.
[0004] There is no universal, two-sided, portable distance warning system that works without a mobile network and can simultaneously enable both approach and targeted search. The core of the invention
[0005] The invention consists of two or more electronic tags / trackers that have the following function. 1. Area monitoring
[0006] Each tracker detects when a corresponding counter-tracker is within a defined distance range. 2. Real-time warning
[0007] Approach triggers the following warnings: *Acoustically *Visually *Optional vibration alarm. This works without a smartphone, directly on the device itself. 3. ID - Assignment (pair binding)
[0008] Each tracker can only integrate with a specific counterpart – similar to the starter chip card – idea: *unique ID, *unambiguous pairing *counterfeit-proof, *Not copyable. 4. Position and direction indicator (optional)
[0009] The tracker can display or audibly signal from which direction the other person is approaching (the "hot / cold" principle). 5. Search mode
[0010] Inverse function: Not rejecting, but actively seeking out (e.g., children, hiking groups). 6. Battery safety
[0011] *long-lasting batteries, *Low battery warning, *Energy-saving stand-by mode. 7. Extended family or group ties
[0012] Multiple trackers can be assigned to one person (e.g., parents, children, grandparents). 8. Independently functioning device
[0013] Independent of: *Mobile network *Internet *Smartphone --High reliability. Example of implementation
[0014] A state-monitored offender wears an electronic ankle monitor. The person at risk wears a corresponding personal tracker. *If the perpetrator approaches within a defined radius, the ankle bracelet activates the alarm for the victim. *The tracker reports: *Alarm, *Direction, Distance decrease, *Request to seek shelter.
[0015] In outdoor operations, the system serves for position tracking, group coordination and loss prevention. Advantages of the invention *Massive reduction in attacks in cases of domestic violence. *International deployment capability (worldwide demand) *Very fast, cost-effective implementation possible. *Extremely high security, as it is not dependent on a network. *Also universally applicable for civilian areas.
[0016] Patentable / Licensable worldwide.
Claims
[1] A portable electronic security system comprising at least two interconnected units that: - detect the distance between the units, automatically trigger warning signals when a defined minimum distance is breached, - store movement and proximity data, and - transmit the stored data to external devices or systems. Electronic distance monitoring system consisting of at least two portable trackers with individual, tamper-proof pair identification, which automatically detect approach below a defined distance threshold and trigger warning signals. [2] System according to claim 1, characterized by that warnings are given acoustically, visually and / or tactilely and function independently of mobile network and smartphone. [3] System according to claim 1 or 2 , characterized by , that the tracker detects and outputs changes in direction and distance to the counter-tracker. [4] System according to one of the preceding claims with energy-saving power supply, charge monitoring and automatic pre-warning when battery level is low. [5] System according to one of the preceding claims with search function (“hot / cold”) which actively navigates users to the other tracker.
