20220026779 · 2022-01-27 ·

A robotic fiber switching system switching between two sets of patch cords is disclosed. The connectors for inner patch cords are placed on multiple layers of stackable rotors which moves into the targeted port by utilizing the interaction of magnetically activated coils and nearby magnets. Multiple layers of stackable stator base are placed outside of the stackable rotors, around which the outer patch cords are placed. To establish a connection, a robot sliding on a rail surrounding the stackable stator is configured to move to the targeted port on the rail, using a robotic arm to pull the corresponding outer patch cord connector from a parking stand and latch it into the adaptor of the inner patch cord at the targeted port.

20210362272 · 2021-11-25 ·

A system that uses a scalable array of individually controllable laser beams that are generated by a fiber array system to process materials into an object. The adaptive control of individual beams may include beam power, focal spot width, centroid position, scanning orientation, amplitude and frequency, piston phase and polarization states of individual beams. Laser beam arrays may be arranged in a two dimensional cluster and configured to provide a pre-defined spatiotemporal laser power density distribution, or may be arranged linearly and configured to provide oscillating focal spots along a wide processing line. These systems may also have a set of material sensors that gather information on a material and environment immediately before, during, and immediately after processing, or a set of thermal management modules that pre-heat and post-heat material to control thermal gradient, or both.

Animated optical security feature

An optical device includes an array of lenses and a plurality of segments disposed under the array of lenses. The plurality of segments corresponds to a plurality of images. Upon tilting the device at different viewing angle, the array of lenses presents images sequentially. In some examples, individual ones of the segments can comprise specular reflecting, transparent, diffusely reflecting, and/or diffusely transmissive features. In some examples, individual ones of the segments can comprise transparent and non-transparent regions. Some examples can incorporate more than one region producing an optical effect.
