Systems Using Filtering And Bypassing TRIZ Cases

Variable impedance switching lets mobile devices share one terminal for power and PLC data, reducing pin count while supporting faster transfer.

Connector-linked energy harvesters and loads share power and data on one wiring network, avoiding fixed infrastructure while preserving portability.

Mode conversion and filtering turn weak open-wire surface wave coupling into a pure low-order mode with higher transmission energy and lower crosstalk.

Variable impedance lets one mobile connection terminal handle both power and data, removing extra pins while supporting low- and high-speed PLC.

Detachable energy-harvesting and load modules share one wiring member for power and data, enabling portable PLC networks without fixed infrastructure.

Firmware reuses legacy TWACS meter circuitry as an ADC to observe powerline waveforms, cut false synchronizations, and improve message detection.

Existing DAC, comparator, and firmware are repurposed to sample powerline waveforms, improving TWACS detection and reducing false synchronization.

Adjustable inductance tunes existing capacitive voltage dividers for reliable medium-voltage PLC without dedicated couplers or power interruption.

A dual-arm weighting filter combines attenuation and sub-band filtering to simplify PLC AFE design while preserving SNR and PSD compliance.

Capacitive isolation passes AC signals and derives DC power across floating grounds, preserving digital transfer during high-voltage transients.

Capacitive isolation, transient filters, and floating grounds protect clock signals and data transfer between high- and low-voltage circuits.

Passive transformer and filter networks isolate transmit and receive paths across bands without bulky duplexers, dummy loads, or complex matching.

A two-branch weighting filter combines attenuation and band filtering to simplify 0-500 MHz power line transceivers while preserving PSD shaping.

Diverter members split carrier data from AC power so one standard cable can handle both, reducing outlet count, block bulk, and cable cost.

Dual-port PLC detectors, filtering, and adaptive noise injection block and detect power line communication despite parasitic paths and low SNR.

Capacitive coupling and edge detection send data over power and ground contacts, cutting pin count, cost, and electromagnetic interference.

Dual-port detectors, PLC filters, and noise generators counter parasitic paths and weak-signal PLC communication.

Power line communication carries power and data to storage-device controllers, reducing separate cabling, installation space, and maintenance time.

Phase-inverted noise cancellation isolates inverter noise on power lines, improving long-distance PLC reliability while reducing circuit volume.

A power line communication device uses a switching unit to toggle between noise detection and filtering modes.
