Telemetry/Telecontrol Selection Arrangements TRIZ Cases
- Lossless Telemetry Compression with Stream Separation and Shuffling
Separating PCM and image streams, then compressing and shuffling them, raises lossless telemetry compression while keeping delay and complexity low.
- Multi-Optical Sensor Circuit Using Signal Modulation Against Crosstalk
Different modulation factors separate signals from multiple optical sensors, reducing ambient-light errors, crosstalk, and circuit complexity.
- Mobile Hearing Aid Control for Adaptive Gain in Noisy Environments
Environmental signal analysis on a mobile terminal updates hearing aid gain in real time to reduce acoustic shock in noisy settings.
- Crosspoint Switch Buffer Correction for Long Signal Cascades
Individual buffer correction in a crosspoint switch limits compounded gain, offset, and duty-cycle errors to preserve signal integrity.
- Lossless Telemetry Compression with Data Classification and Shuffling
Separating PCM and image streams, then shuffling compressed bitstreams, raises lossless telemetry compression while keeping delay and complexity low.
- Automatic Analog Input Circuit for Multi-Sensor Signal Conversion
A processor-driven analog input circuit identifies sensor characteristics and converts 4-20mA or voltage outputs without separate hardware.
- Adaptive Delta Encoding for Compression Without DPCM Drift
Adaptive bit allocation encodes data changes in fewer bits while handling out-of-range deltas to reduce DPCM drift and data volume.
- Mobile Hearing Aid Control for Adaptive Gain and Acoustic Shock Prevention
Environmental signal analysis in a mobile terminal adjusts hearing aid gain in real time to match user hearing and prevent acoustic shock.
- Wireless IC Tag Reader Beam Steering to Prevent Dead Spots
A narrow transmit beam with adjustable direction and a wider receive beam reduces radio-wave interference and prevents tag-reading dead spots.
