Force Measurement By Measuring Frquency Variations TRIZ Cases
- Optomechanical Pressure Measurement Using Membrane Ring-Down
A vibrating membrane detects pressure via optical phase shifts.
- Tamper Detection Guard Ring for Payment Terminals
Guard rings detect conductive fluid injection to prevent data theft while minimizing false alarms from voltage variations.
- Nested Sensing Device for Load Pin Strain Measurement
An elongate member nested inside a load pin receptacle measures axial strain accurately, reducing component weight and preventing plastic deformation.
- In-Plane Vibrating Beam Accelerometer with Single Anchor Isolation
A vibrating beam accelerometer minimizes bias errors from thermal expansion mismatch by consolidating multiple anchors into one primary mechanical anchor.
- High Al Ferritic Steel Sensor Substrate Adhesion
A high aluminiferous ferritic stainless steel sheet matches crystallized glass thermal expansion to ensure strong interdiffusion bonding.
- Capacitive Force Sensor for Touch Screen Intent Recognition
A capacitive force sensor measures touch pressure to distinguish user intent from accidental contact.
- Pressure Sensing Module Eliminates Wires for Case Closure Detection
An elastic cover moves a conductive unit to touch a pad upon pressure, creating a direct electrical connection.
- Piezoelectric Polymer Sensor for Crimp Force Measurement
Piezoelectric polymer films replace ceramic rings to resolve low signal output and shunting effects in lighter gauge wire crimping applications.
- Active Waveguide Sensor for Harsh Environment Measurement
Active waveguide sensors transmit ultrasonic energy through wires to separate temperature and strain effects.
- Non-Concentric Rotor Antenna Traces for Rotary Sensor Cross-Talk Reduction
Non-concentric trace layouts on rotor antennas minimize cross-talk interference, ensuring accurate data transmission in rotary sensor systems.
- Towing Hook Load Measurement via Resonance Frequency
A towing hook arrangement measures applied load by detecting natural frequency harmonics imparted by an actuator.
