Volume Measurement Apparatus/Methods TRIZ Cases

Image analysis estimates blood volume on disposable substrates using pixel counting, resolving quantitation accuracy issues in non-laboratory settings.

A monitoring system senses gas temperature, pressure, and stroke during landing events to calculate transient pressure coefficients.

Pressure sensors calculate injected fluid mass from housing pressure changes, resolving shot-to-shot variation measurement limits.

Heated sensor surfaces measure unknown liquid flow rates via evaporation, preventing chamber saturation and maintaining accuracy over long durations.

Sealed replenishment port transfers toner while maintaining cartridge integrity, preventing airborne contamination during in-situ refills.

Stereo cameras determine container angle via image processing, resolving measurement precision versus productivity trade-offs without physical contact.

A pneumatic probe detects fluid levels using a reconfigurable insertion head and movable backstop to seal reservoir ports.

Parallel and perpendicular acoustic probes measure wave speeds to locate fluid interfaces, resolving measurement precision issues in horizontal wells.

A digital profile of an open container enables precise liquid volume estimation through automated image analysis.

Optical detection calculates drop volume without liquid contact, eliminating cleaning needs while maintaining high measurement accuracy.

A single probe merges transit time and capacitance measurements to determine filling levels, resolving unreliable readings caused by foaming or emulsification.

Capacitive sensor distinguishes product from air in gear flow meter, eliminating false rotation readings and ensuring accurate volume measurement.
