Sliding cams enable independent tilt adjustment of middle lenses, resolving optical axis alignment errors.

Groove geometry retains rolling elements to prevent drop-out, eliminating restriction pins and improving reliability.

Chip On Board LEDs in a plug-in outlet illuminate multiple nearby areas by distributing emission across a single substrate, eliminating bright spot points.

A flexible substrate connects a Hall sensor to a fixed magnet in an image stabilization unit, with holding portions overlapping the sensor mounting area along the optical axis.

Nested concave and convex mirrors inside a solid transparent substrate enable compact femtoprojectors that maintain image quality despite size constraints.

A projection device uses a wavelength converting coating on the mask to emit optical information with consistent color across viewing angles.

Linear rolling guides constrain movable members to reduce perpendicular width, preventing wall contact that deteriorates operational stability.

A rotatable reflection module with ball bearings and electromagnetic drives corrects camera shake within compact housings.

A camera head system uses PCB stator motors to drive roll, tilt, and pan movements directly.

A transparent projection screen uses surface irregularities to scatter light for wide viewing angles.

A camera aperture module uses a magnet, coil, and position detector to drive precise lens barrel adjustments via closed-loop control.

Dual lens units move perpendicular to the optical axis to enable tilt image pickup with precise composition control.

Laterally directed FOLED illumination expands the viewable area while reducing the endoscope diameter by removing bulky optical fibers.

A projector connecting unit houses a rotatable connector that extends for use and retracts into the body.

Nested optical element driving mechanisms reduce system volume while maintaining durability through merged circuit and actuation structures.

Elastically supported ball members enable multi-axis lens rotation, resolving shake compensation limits in portable devices.

A processor dynamically adjusts anti-noise gain to balance sound levels across left and right earphone interfaces.

Rotating the reflection module extends the optical path without increasing the camera module length.

An optical module directs and splits a light beam from an image projection source to provide illumination for a display device.

Guide ducts with chamfers compress and align lateral fiber bundles in endoscope optics, doubling light output for oblique line-of-sight illumination.

Electromagnetic forces pivot a transparent element to boost resolution while lowering power consumption and reducing projector volume.

A zoom lens uses a negative partial group moving perpendicular to the optical axis to correct image blur.

Elastic member biases lens holders toward each other along the optical axis, resolving the trade-off between high positioning accuracy and compact system size.
