Memory Record Carrier Reading Problems TRIZ Cases
- RFID Read Area Definition Device Preamble Jamming
An RFID Read Area Definition Device transmits a modulated carrier during reader preambles to block adjacent tag recognition.
- RFID Tag Tunneling Extended Services for Multi-Sensor Communication
Tunneling sensor information via ISO 18000-7 signals eliminates redundant software modules and reduces device complexity.
- Weighted AP RSSI Summation for Multi-Floor Wireless Location
Selective weighting of access point signal strengths suppresses outlier influences in atriums, reducing floor determination errors and processing delays.
- Two-State Symmetric Protocol for RFID Tag Identification
Persistent node state management prevents missed tags during inventory cycles, ensuring complete and timely device detection.
- RFID Systems Using Twisted Pair Cables for Extended Range
Twisted pair cables replace coaxial lines to extend UHF RFID range to 150 meters while maintaining signal integrity.
- RFID Transponder Security via Technology Release Code Segmentation
A read/write device obtains a technology release code from an RFID transponder to dynamically set access rights for the module.
- Modular Chip Card Reader With Removable Carrier
Removable module carriers with shielding reduce electromagnetic interference and maintain communication precision during quick replacements.
