Devices With Sensor TRIZ Cases
- Mobile Device Orientation Detection Reducing Power Consumption
Accelerometer calculates mobile device orientation to keep display and camera off, preventing unnecessary battery drain from false activations.
- Mobile Terminal Direction Indication via Network Location and Magnetic Correction
A mobile communication terminal retrieves location data from network identification information to display destination direction without GPS hardware.
- Multi-Sensor Stowed State Verification for Electronic Devices
Cross-referencing proximity, touch, and imager signals prevents false gesture control when primary sensors malfunction.
- Barometric Sensor Calibration for Altitude Accuracy
A barometric sensor calibration process determines a pressure offset using location data to adjust altitude readings.
- Touch Screen Gesture Disambiguation via Distance Thresholding
Portable multifunction devices detect finger-down and finger-up events on a touch screen display to determine user input position.
- Infrared Proximity Sensor Threshold Adjustment for Lens Degradation
Compares current reflected infrared ray intensity against stored baselines to modify sensing thresholds when lens transmittance drops due to dust or abrasion.
- Portable Terminal Display Brightness Control via Temperature Mapping
A portable terminal adjusts display brightness using a stored temperature-to-brightness lookup table.
- Mobile Device Walking Safety Control via Sensor Fusion
A mobile electronic apparatus uses sensor fusion to detect user walking states and adjust display output for situational awareness.
- Handheld Device Surface Reflectance Estimation
A handheld device estimates surface reflectance using orientation and light sensors to adjust display modes.
