Publication number: 20240107757Abstract: Embodiments of semiconductor devices and methods for forming the semiconductor devices are disclosed. In an example, a method for forming device openings includes forming a material layer over a first region and a second region of a substrate, the first region being adjacent to the second region, forming a mask layer over the material layer, the mask layer covering the first region and the second region, and forming a patterning layer over the mask layer. The patterning layer covers the first region and the second region and including openings corresponding to the first region. The plurality of openings includes a first opening adjacent to a boundary between the first region and the second region and a second opening further away from the boundary. Along a plane parallel to a top surface of the substrate, a size of the first opening is greater than a size of the second opening.Type: ApplicationFiled: December 8, 2023Publication date: March 28, 2024Inventors: Jia He, Haihui Huang, Fandong Liu, Yaohua Yang, Peizhen Hong, Zhiliang Xia, Zongliang Huo, Yaobin Feng, Baoyou Chen, Qingchen Cao

Patent number: 11702805Abstract: Surrogates for roadside objects, such as concrete curbs, can be used for vehicle testing. A surrogate for a concrete curb can substantially be similar in size and/or shape as the concrete curb that the surrogate is mimicking. The surrogate can be configured to exhibit substantially the same characteristics as their actual counterpart concrete curb when sensed by one or more vehicle sensors (e.g., cameras, radar sensors, and/or LIDAR sensors). Such surrogates can be used to test automated vehicles, one or more vehicle sensors, a vehicle sensor system, and/or one or more vehicle system (e.g., a road departure mitigation system). The surrogates can be configured to withstand being impacted by a test vehicle without being damaged and without damaging the test vehicle.Type: GrantFiled: December 3, 2019Date of Patent: July 18, 2023Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., The Trustees of Indiana UniversityInventors: Rini Sherony, Stanley Yung-Ping Chien, Seeta Ram Pandey, Wensen Niu, Yaobin Chen

Publication number: 20200240091Abstract: Surrogates for roadside objects can be used for vehicle testing. A grass surrogate can be configured to exhibit substantially the same characteristics as natural grass when sensed by one or more vehicle sensors (e.g., cameras, radar sensors, and/or LIDAR sensors). Such surrogates can be used to test autonomous vehicles, one or more vehicle sensors, a vehicle sensor system, and/or one or more vehicle systems (e.g., a road departure mitigation system). The grass surrogate can help a vehicle to identify road boundaries, particularly in portions of a road that do not include lane markings. The grass surrogate can be configured to withstand being driven over by a test vehicle without being damaged and/or without damaging the test vehicle. In some arrangements, the grass surrogate can include artificial grass that is coated with a mixture of high gloss acrylic paint and high reflectance pigments.Type: ApplicationFiled: January 24, 2019Publication date: July 30, 2020Inventors: Rini Sherony, Stanley Yung-Ping Chien, Qiang Yi, Jun Lin, Abir Saha, Yaobin Chen, Chi-Chih Chen

Patent number: 9454888Abstract: Systems, apparatuses and methods for detecting internal cell faults using online and real-time sensing techniques, and providing an accurate and reliable early warning for the incoming failure of battery cells hours or days prior to failure. A system is configured to perform real-time and direct measurement of battery cell parameters of temperature, voltage, and AC impedance through online sensing. These parameters may be simultaneously processed using advanced probabilistic and/or fuzzy logic-based algorithms to provide an early warning for the incoming failure of battery cells in a battery pack. This technology may safeguard the LIB battery packs while allowing them to operate at or near 100% capacity in both transportation and stationary applications.Type: GrantFiled: October 27, 2015Date of Patent: September 27, 2016Assignee: Indiana University Research and Technology CorporationInventors: Jian Xie, Jie Chen, Lingxi Li, Yaobin Chen

Patent number: 5553609Abstract: A computer-based remote visual monitoring system is provided for in-home patient health care from a remote location via ordinary telephone lines. The system includes a supervisory control center having access to patient and health care professional databases for assigning patients to appropriate health care professionals and for performing task planning. A number of master monitoring computers are linked to the control center and are accessible by a corresponding number of health care professionals. A slave monitoring computer is located within the homes of a plurality of patients and may be linked via telephone modems to any of the master monitoring computers. Audio/visual equipment at both locations permits real-time two-way communications during an "in-home" visit to a patient by a health care professional from a remote location.Type: GrantFiled: February 9, 1995Date of Patent: September 10, 1996Assignees: Visiting Nurse Service, Inc., Indiana University FoundationInventors: Yaobin Chen, Thomas G.
