Memory Record Carrier Reading Problems TRIZ Cases
- Data Carrier Inventory With Segmented Transmission Parameters
Segmented transmission parameters allow data carriers to generate response signals after inventory without quiescent state reset.
- RFID Inventory System Using Master Tag Segmentation
Segmenting master and area RFID tags resolves the contradiction between tracking capability and location accuracy.
- Serial RFID Transmitter Relay Architecture for Extended Tag Tracking
Serially connected transmitters relay identification impulses to extend reading range across large retail areas.
- Tandem Contactless Cards for Scalable Memory Upgrades
Dual contactless cards share a single user ID to operate in tandem, expanding memory capacity without physical modifications.
- RFID Tag Substation Base Station Object Search System
A hierarchical RFID tag substation base station architecture reduces manual search time by processing query signals across distributed substations.
- RFID Interrogator Interference Controller for Signal Channel Management
An RFID interrogator interference controller detects signal presence and power levels in frequency channels to manage transmission timing.
- RFID Inventory Control System for Retail Tracking
A distributed RFID reader network and monitoring server automate inventory updates, eliminating manual barcode scanning errors.
- Wireless Smart Card Reader Connection Control
A wireless smart card reader manages concurrent device connections through mobile device authorization.
- Multiplexed RFID Verification for Single-Use Bioprocessing Connections
A multiplexed RFID transceiver interrogates passive tags on single-use connectors to verify physical attachment status.
- Security Controller Power Switching for Mobile Authentication
A security controller switches to electromagnetic field power when battery voltage drops, maintaining noncontact authentication functions.
- Multi-Mode Active Antenna for RFID Printer-Encoder
A multi-mode active antenna configures distinct radiation patterns to steer signals toward specific RFID tags.
- RFID Tag Security via Asymmetric Channel Protection
An RFID tag uses its secure channel to transmit random data for encoding reader-to-tag writes, preventing unauthorized data injection while avoiding high costs.
