Acceleration Measurement Using Interia Forces TRIZ Cases

Distributing wirings through multiple bonding regions stabilizes airtightness and prevents leaks caused by uneven stress concentration.

Dual frequency mode opto-mechanical resonator cancels temperature drift by measuring the difference between two resonance frequencies.

Replacing dual magnets with a single unit ensures identical minor loop slopes, eliminating imbalance errors and improving measurement accuracy.

Angled detection laser beam selects atomic velocities to maintain interferometer signal contrast across accelerations exceeding ±1g.

Resin covering portions suppress solder fillet rise on terminal electrodes, preventing movement limitations and improving detection accuracy.

Inverting conventional mode configurations reduces cross-talk sensitivity while simplifying circuitry for reliable three-axis sensing.

Segmented Coriolis masses in a yaw rate sensor compensate for rotational acceleration interference through differential capacitance measurement.

Groove portions on the outer edge of a physical quantity sensor element suppress leakage vibration and force transmission.

Recessed insulating portions and dummy electrodes in a capacitive acceleration sensor reduce electrostatic attraction, preventing movable body sticking.

A tri-axis angular rate sensor uses a single planar sense frame to detect rotation about three perpendicular axes via Coriolis forces.

Cylindrical piezoelectric transducers extend as cantilever beams from a bulkhead partition to form a compact vector sensor.
