Circuit Authentication TRIZ Cases
- Biometric Sensor Optical Link for Wireless Charging Data Reliability
A biometric sensor reuses its LED and light receiver as an optical data link, avoiding noisy power-signal communication during wireless charging.
- EV Charge-Discharge Authentication Using Broadcast Control Signals
Broadcast control signals let EV charge-discharge elements request local permission, cutting server load and blocking unauthorized facility use.
- ENDS Age Verification via Audio and Optical Control Signals
Audio tones or optical signals unlock an ENDS device only after age verification, reducing unauthorized use without complex onboard authentication.
- Vehicle Charging Communication Priority for Multi-Standard Connection
Wireless-first, priority-based charging communication helps vehicles connect across multiple standards and use automatic charging or Plug & Charge.
- EV Charging Control for Dynamic ISO 15118 Standard Selection
User-driven ISO 15118 standard switching shortens EV charging connection setup by avoiding unwanted VPP-first negotiation.
- Vehicle Wireless Charging Coil Alignment Under Acceleration
Horizontal acceleration sensing lets the control unit track phone movement and reposition the transmitting coil to sustain in-vehicle charging efficiency.
- Single-Wire Module Detection Using Charge-and-Sample Voltage Sensing
Charging the SWI line, then sampling its voltage, enables fast module presence detection with minimal communication overhead and no added hardware.
- Power Storage Pack Authentication via Current Pattern Resistance Check
A current-pattern authentication flow also measures pack-to-vehicle contact resistance, helping prevent battery misidentification and unsafe connections.
- EV Charging Authentication Using Battery Deterioration Thresholds
Mutual authentication and tamper-resistant deterioration records let charging stations block worn batteries and maintain EV power availability.
- Moveable EV Charging Arm With DC Pulse Fault Testing
DC pulse charging with testing between high-voltage pulses speeds EV charging while detecting faults to protect the vehicle and station.
- Underground EV Charging Connector Alignment for Tight Kerbside Space
Sensors and a movable under-parking connector align with the vehicle inlet, enabling EV charging where kerbside space is limited.
