Anti-Theft Devices TRIZ Cases

Motion-triggered cameras and neural network image analysis detect cargo bay theft and damage while reducing manual inspection.

RFID authentication restricts prime mover output until code entry, helping prevent unauthorized use while enabling operator-specific vehicle modes.

Two independent circuits detect the intermediate key position and control key locking in a compact ignition switch for safer operation.

Fusing phase shift with time-of-flight improves wireless ranging accuracy while reducing receiver switching and power use in battery devices.

Dynamic window transmittance and HUD imagery help occupants perceive the surroundings in rain or snow when direct visibility is poor.

Software-based vehicle anti-theft uses the embedded automotive network for remote ignition blocking and performance limiting without relays.

A cloud-mediated random-number check replaces synchronized rolling codes to block Rolljam and denial-of-service attacks in vehicle entry.

Automatic key-state detection sets or stops the remote immobilizer without manual center requests, improving relay-attack security and ease of use.

Timed activation zones combine passive entry signals with user detection to open the right vehicle door securely for authorized passengers.

Uses charge from a personal electronic device plus authentication to unlock a power-locked panel when vehicle battery power is too low.

Millimeter-wave radar with Gabor filtering identifies human foot trajectories for reliable trunk access in rain, dust, low light, and EMC noise.

Multi-smart-key verification blocks unauthorized face registration in vehicles while preserving convenient biometric access and optional fingerprint checks.

Relative-distance monitoring between IoT devices triggers alerts and lockout when a device moves beyond a set proximity limit.

Short-range time-of-flight measurement verifies key-to-vehicle proximity, blocking relay-based unlocking and ignition in passive entry systems.

Behavior analysis of nearby people helps autonomous delivery vehicles distinguish theft intent from normal obstacles and cut false alarms.

An in-vehicle key case uses adjustable actuators and remote signaling to enable unattended key delivery without exposed external lockboxes.

Motion-triggered in-vehicle cameras and ID authentication help detect unauthorized entry and protect unattended occupants with real-time alerts.

When facial features disappear at odd head angles, secondary landmark and gait tracking maintain user authentication with lower latency.

Satellite-aided key tracking triggers air-conditioning, charging, and conditioning before entry to cut wear and improve start readiness.

BLE proximity detection wakes selected vehicle controllers before arrival, cutting standby power without delaying passive entry.

A processor coordinates the lock, tailgate, and ejector from one input, cutting dump time and operator error in refuse vehicles.

When a theft alert cannot be transmitted, this vehicle security logic blocks powertrain start to preserve traceability and alarm reliability.

Real-time facial recognition identifies irregular driver health events, sends alerts, and can trigger vehicle safety actions or emergency contact.

Cloud-managed e-Keys let vehicles grant temporary, condition-based access while authenticating users and enforcing usage privileges.

Sensor-based closure uses object presence, user proximity, and risk conditions to secure vehicle compartments during autonomous loading.

Distance-based control disables smart key radio and sets the immobilizer when the user terminal is too far from the vehicle, blocking relay attacks.

Passive NFC energy harvesting powers an enclosure entry PCB to trigger RF door access without primary battery dependence or long-range signal loss.

Sensor fusion and vehicle-state checks detect catalytic converter theft while suppressing false alarms during driving or engine operation.

Signal strength, latency, and user intent checks help wireless access control block relay attacks without losing seamless lock opening.

Biometric contact sensing and body-channel seat verification tie each driving session to the authenticated driver without portable keys.
