Sensing By Mechanical Means TRIZ Cases
- Barcode Scanner Rotational Assembly With Nested Low-Clearance Housing
A nested curved housing and ratchet linkage enable stable scanner rotation while shielding moving parts and reducing finger-pinch risk.
- Data Card Enclosure with External Ports for Server Access
External communication ports on a data card enclosure provide direct access to internal connectors without opening the housing.
- Physical Interactive IDs for Mass-Produced Object Identification
Replacing digital encoding systems with mechanical bump structures to reduce manufacturing complexity while maintaining object identification capability.
- Secure Smart Card Reader Logging and Signature Generation
A secure smart card reader logs security events and generates cryptographic signatures to verify user interactions.
- Combined RFID and Optical Imaging Module for Medical Device Tracking
A unified module merges an optical imager and RFID reader through a single host interface to capture barcode and wireless identification data.
- Automated Item Assistance System Using Sensor Identification
Sensors detect items in a locale to trigger automatic manual retrieval, eliminating the need for users to track physical documentation.
- Compact Token Receptacle Footprint Reduction
Integrating electrical contacts in a dense-packed configuration reduces the physical space occupied by the token receptacle on host devices.
- Dual-Layer Smart Card Phone With Magnetic Coupling
A dual-layer smart card phone couples a master unit and slave unit via magnetized contact pads for secure financial transactions.
- Information Bearing Medium with Marked Unit Data Zones for Accurate Code Detection
Distinct mark patterns in adjacent unit data zone strings prevent mis-recognition of sequentially arranged convex portions during high-speed detection.
- Compact Card Reader with Top-Insertion and Integrated Housing
A compact card reader merges the housing into a single metal casing to hold an electronic card securely.
- Geolocation Cross-Reference for Internet User Authentication
Cross-references IP address and voice device locations to verify internet user identity, preventing fraud from mismatched geographical proximity.
- 2D Sensor Array Barcode Decoding via Aiming Pattern Illumination
A two-dimensional sensor array uses an aiming pattern to illuminate and decode barcodes.
- Card Reader Audio USB Mode Switching
A card reader switches between audio and USB modules for data communication.
- Passive Magnetic Identification for Surgical Instruments
A passive identification device uses a rotating magnetic object to generate unique induction signals for tracking medical tools.
- ATM Anti-Fraud System Using Radiation Jamming and Segmented Sensing
Segmented radiation sensing detects skimmers while periodic jamming signals block data theft without continuous energy drain.
- Oscillating Card Stand for Wear-Free Contact
An oscillating card stand limits contact duration to prevent wear on electronic cards during data transfer.
