Volume Measurement Apparatus/Methods TRIZ Cases
- Electronic IV Tags for Accurate Line Association and Fluid Monitoring
A clamped tag combines sensing, display, and wireless feedback to reduce IV line mismatches, manual tracing, and expired-set errors.
- Diaper Urine Volume Detection with Pulsed Light and Activity Sensing
A photodetector removes ambient light interference while activity sensing corrects movement effects in diaper urine volume estimation.
- Flexible Ink Pouch Empty-State Detection via Pump Signal Frequency
Pump signal frequency detects empty flexible ink pouches when vertical fill-level sensing becomes unreliable.
- Event Sensor Dispenser Droplet Detection Beyond Frame-Rate Limits
An event sensor detects dispenser droplets through luminance changes, avoiding limited per-droplet images from high-speed cameras.
- Electromagnetic Liquid Level Indicator Using Eddy Currents
Replacing mechanical floats with wireless electromagnetic detection eliminates internal wear and fire hazards in fuel tanks.
- Flexible Envelope Gas Volume Measurement Device
A flexible envelope collects gas at constant pressure, enabling accurate volumetric metering without condensation bias.
- Optical Fluid Level Sensing Arrays for Aircraft
A modular fluid level sensing system uses optical nodes to detect liquid presence without manual calibration.
- Movable Ultrasonic Transducer for Aircraft Fluid Level Measurement
A movable ultrasonic transducer measures fluid levels through tank walls, eliminating the weight and complexity of fixed sensor installations.
