Patent number: 12236695Abstract: A computer-implemented system and method relate to certified defense against adversarial patch attacks. A set of one-mask images is generated using a first mask at a set of predetermined regions of a source image. The source image is obtained from a sensor. A set of one-mask predictions is generated, via a machine learning system, based on the set of one-mask images. A first one-mask image is extracted from the set of one-mask images. The first one-mask image is associated with a first one-mask prediction that is identified as a minority amongst the set of one-mask predictions. A set of two-mask images is generated by masking the first one-mask image using a set of second masks. The set of second masks include at least a first submask and a second submask in which a dimension of the first submask is less than a dimension of the first mask. A set of two-mask predictions is generated based on the set of two-mask images.Type: GrantFiled: September 21, 2022Date of Patent: February 25, 2025Assignee: Robert Bosch GmbHInventors: Shuhua Yu, Aniruddha Saha, Chaithanya Kumar Mummadi, Wan-Yi Lin

Patent number: 11956994Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.Type: GrantFiled: August 10, 2021Date of Patent: April 9, 2024Assignee: Applied Materials, Inc.Inventors: Chung-Chih Wu, Hoang Yan Lin, Guo-Dong Su, Zih-Rou Cyue, Li-Yu Yu, Wei-Kai Lee, Guan-Yu Chen, Chung-Chia Chen, Wan-Yu Lin, Gang Yu, Byung-Sung Kwak, Robert Jan Visser, Chi-Jui Chang
