Publication number: 20230384502Abstract: An apparatus including a first ferrule, a second ferrule and a tracing fiber. The first ferrule may comprise a cap. The second ferrule may comprise the cap. The tracing fiber may be configured to propagate light from the first ferrule to the second ferrule. The first ferrule may enable the light to be directed into the tracing fiber when the cap is removed. The cap of the second ferrule may be configured to scatter the light to provide an omnidirectional emission of the light from the second ferrule. The tracing fiber may be bundled with one or more data carrying lines in a cable. Each of the data carrying lines may be configured to enable a communication of data. The tracing fiber may be configured to propagate the light without interrupting the communication of data.Type: ApplicationFiled: June 6, 2023Publication date: November 30, 2023Inventor: Jamyuen Ko

Patent number: 11635632Abstract: This document describes a mirror-based microelectromechanical system (MEMS) for optical image stabilization in image-capture systems. The mirror-based MEMS includes a MEMS platform that can rotate about a pitch axis and/or a yaw axis. MEMS rotors drive rotational motion of the MEMS platform. One or more piezo films, flexibly connected to the stationary platform, extend over the MEMS rotors. The piezo films have a resistance value that varies when the piezo films are deformed by the MEMS rotors. The piezo films form a bridge circuit across the MEMS platform, which produces an output voltage that varies with the resistance values. A MEMS mirror, coupled to the MEMS platform, reflects light rays to an image sensor. A microcontroller receives pitch and yaw information from the image sensor. The microcontroller accesses the output voltage and determines how much to move the MEMS platform to compensate for the pitch and yaw of the camera.Type: GrantFiled: April 12, 2021Date of Patent: April 25, 2023Assignee: Google LLCInventors: Jamyuen Ko, Chung Chun Wan
