Telephonic Communication TRIZ Cases
- PSTN Modem Quick Connection Protocol
A PSTN modem connection protocol identifies channel characteristics and configures echo compensators to enable rapid duplex data transmission.
- Collaborative Location Estimation Using Intermediary Devices
A collaborative estimation system derives device location and orientation by combining signals from multiple sources.
- Real-Time Tracking System for Multi-Object Communities
A tracking system monitors persons and objects in real-time using GPS and RFID localization technologies.
- Communication Apparatus Address Segmentation for Transmission Accuracy
A communication apparatus manages transmission addresses by segmenting storage areas for distinct systems to ensure accurate data routing.
- Secure Financial Transaction System Using NFC Key Exchange
A communication system exchanges encryption keys via near field communication to authorize financial transactions.
- Radio Resource Allocation Using Context-Aware Heat Maps
A radio resource control point facility allocates and schedules resources using user context data.
- Mobile Authentication via Caller ID and Logon Key
A mobile authentication method uses caller identification to send a logon key, enabling secure transaction access with minimal keystrokes.
- Network-Based Location Reminders via Mobile Switching Center
Mobile switching center triggers reminders when user equipment enters a predetermined area, eliminating expensive GPS hardware requirements.
- Tracking Device Tamper Detection Using Metal and AGC Circuits
A tracking device uses metal detection and automatic gain control circuits to identify signal shielding.
- DSL Transmitter Power Allocation via Water-Filling Algorithm
A transmitter device allocates transmission power across wire channels using a fast converging analytical water-filling algorithm.
- Border Control Aggregator for PSTN Connectivity
A border control aggregator consolidates multiple circuit-switched connections to eliminate manual hardware management and reduce infrastructure complexity.
