Multiple receiving antennas and posture beacon signaling keep wireless power stable as instrument orientation changes and help limit human exposure.
Beacon-guided wireless charging powers portable measuring instruments only when unused, reducing radio-wave exposure and battery replacement.
A battery-shaped module plus lid-shaped section enables wireless charging in small instruments without enlarging the standard battery compartment.
A motor-driven collet rotates the micrometer ratchet by button control, enabling one-handed use with faster, more precise measurement.
