Circuit Authentication TRIZ Cases
- Power-Line Battery Pack ID Reading With Dynamic Threshold Setting
Dynamic threshold setting from power-line current or voltage measurements cuts false battery pack ID reads caused by offset variation.
- BLDC Power Tool Inverter Control for High Torque Without Heavier Batteries
Variable conduction-band BLDC control helps one power tool deliver heavy-duty torque while avoiding the battery weight penalty of higher-voltage packs.
- Wireless Charging Carry Case for Multi-Device Power Alignment
Integrated coils and control circuits let one carry case align and apportion wireless power across multiple removable devices without extra chargers.
- Distributed Charging Function for Cross-Area Signaling Reduction
Local charging function nodes cut cross-area charging data transfer, lowering signaling load, network resource use, and operating cost.
- Pressure Sensor Control in Vaping Devices for Low-Power Inhalation Detection
Variable pressure-sensor sampling cuts idle power use while still detecting inhalation quickly to trigger vaporization when needed.
- Industrial Vehicle Battery Identification for Power Supply Control
Connector-state detection identifies battery type and gates power supply in industrial vehicles when battery communication is absent.
- Digital Pen Base Station With Multi-Pen Docking and User Sync
A multi-pen docking cavity combines inductive charging and user authentication to simplify alignment, sharing, and data synchronization.
- Wireless Charger Authentication via Charging Coil Challenge Signals
Charging coil challenge-response authentication secures contactless power transfer while reducing wear, corrosion, and manual charging steps.
- Wireless Power Reception Authentication to Limit Heat and Delay
Conditional mutual authentication skips unnecessary processing and limits wireless power transfer when validation fails, reducing heat and delay.
- Convertible Battery Pack Circuit Layout for Multi-Voltage Power Tools
Injection-molded power traces let one battery pack switch cell connections for different tool voltages, reducing battery variety and weight burden.
- Laptop Charging Cabinet With Conductive Plate Auto-Connection
Conductive charging plates and pronged receivers automate laptop charging in a cabinet while reducing cable wear and enabling device tracking.
- Traction Battery Charging Mode Switching for Low-Temperature Protection
When battery temperature is low, the BMS requests pulse charging from the pile to avoid low-temperature degradation and switch back to DC charging as conditions recover.
- Mobile Terminal USB Detection for Accurate Charger Identification
Interrupt-based D-signal detection helps a mobile terminal distinguish USB data links from chargers despite plug-in speed and pin-length variation.
- Portable Charger Authentication for Fast Wireless Charging Access
Pre-linked battery and user IDs let a service server verify charging rights quickly, cutting delays before wireless portable charger use.
- Cell-Level Battery Monitoring With Self-Healing Failure Isolation
Cell-level monitors use NFC-powered data capture and self-healing switches to track battery history, isolate faults, and support recycling.
- Adapter-Detecting Power Feeder for Safe DC Output Matching
A detecting unit identifies the adapter type before power delivery, matching DC voltage and current to prevent heat, power loss, and device damage.
- Wireless Charger Foreign Object Detection Using Resonant Q Thresholds
Dynamic Q-factor and inductance thresholds detect foreign objects before and during wireless charging to reduce heating, power waste, and damage.
- Wireless Charging Coil FOD Using Q Factor and Inductance
Pre-ping Q factor and inductance checks improve foreign object detection in wireless charging coils, reducing heating, power waste, and damage.
