Transmission Systems TRIZ Cases
- Interactive Dog Training Receiver Remote Control
Receiver plays user sound data via speaker module to resolve owner absence bottleneck during training.
- Adaptive PRACH Preamble Configuration for Cellular Interference Reduction
Base station tunes cyclic shift parameters using historical transmission statistics to optimize physical random access channel preamble construction.
- Variable Time Period Walking Detection for Authentication Recovery
A mobile device authentication system adjusts detection time periods based on acceleration signals to control controlled device operations.
- Packet Discard Point Probing via Sequence Number Analysis
Analyzing IP sequence number gaps identifies exact discard locations in high-speed to low-speed transitions, eliminating complex capture hardware.
- Congruent Unicast Multicast Paths in Service Provider Networks
Modifying PIM protocols to align unicast and multicast paths, eliminating ingress replication bottlenecks and enabling reliable path failure detection.
- Universal Remote Controller for Multi-Room Networked Devices
A universal remote controller uses a touch panel to detect single, double, or long presses and generates specific control commands for electronic devices.
- Wireless Packet Combination Error Correction for Industrial Reliability
Reconstructing error-free packets from multiple erroneous copies prevents data loss in industrial wireless sensor networks without requiring retransmissions.
- Mobile Lighting Control via Context-Aware Sensor Detection
Context-aware sensor detection identifies contributing LED units for direct wireless control, eliminating cumbersome application navigation steps.
- Presence Detection Using Optical Signal Verification
An optical signal verification system prevents accidental target device control by ensuring the mobile device is physically present in the same room.
- Group-Based MTC Communication for Network Congestion
Group-based machine-to-machine communication reduces network congestion by organizing devices into clusters with staggered transmission windows.
