Testing Sensing Arrangements TRIZ Cases

Laser tuning adjusts RFID antenna traces to garment dielectric properties, while welded attachment cuts sewing damage and tag visibility.

Thin washable RFID tags are integrated into textiles with dynamic tuning to preserve antenna performance, comfort, and secure placement.

Dynamic metal-thread antenna sizing lets RFID tags be sewn into garments for better wash resistance, comfort, and theft security.

Thin RFID tags use tuned metal threads or traces sewn into fabric to improve wash durability, comfort, and secure item tracking.

Physical changes and user challenge-response checks help reveal skimming devices on card acceptors before payment data is stolen.

A robot arm moves chip cards between mechanical and electrical test positions to speed wear testing and reduce manual handling.

Capacitive pad arrays detect read-head presence during fast swipes, cutting false alarms and power use in magnetic card communication.

A test terminal simulates card swiping with time-varying magnetic fields, reducing physical card handling and POS testing complexity.

External light sources with attachment optics distribute illumination to prevent camera-facing reflections in 2D barcode scanners.

Embedding a synchronization sequence in RFID signals enables readers to calculate transmission characteristics and extract payload data from collided transmissions.

Distributed sensor nodes enable real-time item tracking and dynamic routing, resolving the trade-off between operational efficiency and system complexity.

A payment terminal evaluator inserts into a chip slot to detect fraudulent overlays.

A CMOS-based optical reader calculates image contrast to assess reading stability and prevent code unreadability.

Image capture devices in optical code scanners compare current performance metrics against stored baselines to detect degradation.

A code scanner determines reading stability by analyzing success rates using a CCD sensor and processor.
