Tariff Metering Apparatus TRIZ Cases
- Utility Meter Radio Communication With Kalman Phase Tracking
Narrow-band interference is handled with decision-directed phase tracking and Kalman feedback, enabling coherent demodulation and earlier meter transmission.
- Secondary Smart Meter Data Collection via P1–P2 Gateway Encapsulation
Gateways encapsulate P1 smart-meter data in P2 business data, while asymmetric signatures support integrity and non-repudiation during infrastructure upgrades.
- Optical Meter Housing Opening Detection Against Gel Interference
An emitter, internal housing reflection, and phototransistor detect meter opening while limiting power use and resisting gel interference.
