Data Processing Applications TRIZ Cases
- Single-Pair Drive-Through Intercom Wiring for Power and Data
A single wire pair carries both DC power and real-time audio data, simplifying drive-through intercom wiring while preserving clear order transmission.
- Instrumentation Amplifier Frontend for Near-Ground Signal Monitoring
A feedback current amplifier enables near-ground signal sensing without negative supplies, supporting continuous meter accuracy monitoring.
- Single-Pair Drive-Through Intercom Link for Power and Digital Audio
Digital order audio and DC power share one wire pair in a drive-through intercom, reducing wiring complexity while improving signal accuracy.
- Drive-Through Intercom Encoding Over Single-Pair Power Wiring
Encoded order audio and DC power share one wire pair in a drive-through intercom, simplifying installation while preserving communication accuracy.
- Instrumentation Amplifier Feedback Circuit for Near-Ground Signals
A feedback current amplifier shifts voltage levels to amplify near-ground input signals without a negative supply and support meter accuracy monitoring.
- Mobile Optical Fingerprint and Document Capture on One Surface
A portable FTIR imaging surface captures multiple fingerprints and documents in one step, speeding in-vehicle identification without losing image quality.
- Virtual Assistant Volume Control for Changing Acoustic Conditions
Automatic volume control combines content, user, distance, and noise criteria to keep virtual assistant responses audible without manual adjustment.
- Portable Optical Scanner for Simultaneous Fingerprint and Document Capture
A dual-angle optical layer captures fingerprints and documents on one portable surface, enabling wireless in-vehicle identification.
- Audio Reproduction Bass Control for Low-Battery Energy Saving
Bass reduction tied to battery charge cuts audio playback power draw, helping extend battery life and vehicle range.
- Floating-Point CAD Compression Using Integer Delta Prediction
Integer-based prediction encodes sign, exponent, and mantissa differences to compress CAD floating-point data losslessly across platforms.
