Publication number: 20250135331Abstract: Dual-function input devices for a computing device may include a housing and an actuator disposed within the housing. The actuator may be pivotable relative to the housing in a first direction and a second direction. The actuator may include a first connector and a second connector. The input devices may include an input lever that is coupleable with the actuator via one of the first connector and the second connector. The actuator may be configurable between a first mode by coupling the input lever with the first connector and a second mode by coupling the input lever with the second connector. In the first mode the input lever and the actuator may be pivotable in the first direction by a first distance. In the second mode the input lever and the actuator may be pivotable in the first direction by a second distance that is greater than the first distance.Type: ApplicationFiled: October 30, 2023Publication date: May 1, 2025Inventors: David Maher, Andrew Kelly, Simon Baumgartner, Cheng Hao Chiu, Baptiste Merminod

Publication number: 20240274636Abstract: A pixel sensor array of an image sensor device described herein may include a deep trench isolation (DTI) structure that includes a plurality of DTI portions that extend into a substrate of the image sensor device. Two or more subsets of the plurality of DTI portions may extend around photodiodes of a pixel sensor of the pixel sensor array, and may extend into the substrate to different depths. The different depths enable the photocurrents generated by the photodiodes to be binned and used to generate unified photocurrent. In particular, the different depths enable photons to intermix in the photodiodes, which enables quadradic phase detection (QPD) binning for increased PDAF performance. The increased PDAF performance may include increased autofocus speed, increased high dynamic range, increased quantum efficiency (QE), and/or increased full well conversion (FWC), among other examples.Type: ApplicationFiled: February 15, 2023Publication date: August 15, 2024Inventors: Ming-Hsien YANG, Chun-Hao CHOU, Kuo-Cheng LEE, Chien Nan TU, Chun-Wei CHIA, Tse-Yu TU, Ya-Min HUNG, Cheng-Hao CHIU, Chun-Liang LU
