Trigometric Functions TRIZ Cases
- Vehicle Combination Drag Prediction Under Crosswind Shape Changes
Predict drag area after trailer or shape changes by rescaling projected area versus air-attack angle, avoiding repeated wind tunnel tests.
- Vehicle Combination Drag Prediction Using Projected Area Rescaling
Projected area rescaling predicts vehicle combination drag under shape changes and crosswind angles without new wind tunnel tests.
- Frequency Response Measurement Using Multi-Sine and Sweep Switching
Switching between multi-sine and sweep signals by Nyquist region cuts measurement time while preserving accurate gain and phase data.
- Drawing-Tool Curve Fitting With Tangent Arcs for CNC Splines
Sectional tangent-arc fitting automates complex CNC spline curves, improving fitting accuracy while reducing manual operations and errors.
- Flexible PWM Sine Wave Generator for Low-Power Resolver Signals
A DDS-based flexible PWM timer generates resolver sine signals with adjustable frequency while cutting die size, latency, and power use.
