Publication number: 20240071812Abstract: A method for forming a semiconductor device includes providing a semiconductor substrate, implanting n-type impurities into a device region in the semiconductor substrate to form an implanted region and an un-implanted region. The method also includes forming an epitaxial layer on the semiconductor substrate and forming a trench surrounding the device region in direct contact with the implanted region. The method further includes performing a selective lateral etch through the trench to remove the implanted region to form a cavity under the epitaxial layer. The un-implanted region is retained to form a pillar under the epitaxial layer. Next, an insulating material is disposed in the cavity and the trench. The method forms a single crystalline region that is separated from the semiconductor substrate by the insulating material except at the pillar.Type: ApplicationFiled: August 30, 2022Publication date: February 29, 2024Inventors: Chung-Lei Chen, Anhao Cheng, Meng-I Kang, Yen-Liang Lin

Patent number: 11027140Abstract: The invention provides an implantable vagal nerve stimulator having a “passive” generating power source that harvests the stomach's movements to transform kinetic energy to electrical charge without the need for a battery. In this regard, the invention is self-powering and is automatically timed to stomach peristalsis. While sporadic stimulation to the vagal nerve would seem too infrequent to cause weight loss effects, electrical stimulation delivered at the optimal time (e.g., during food consumption) has been found to optimize the effects of vagal nerve stimulation, giving the user's brain a “full stomach” signal before the user over-consumes food.Type: GrantFiled: June 15, 2018Date of Patent: June 8, 2021Assignee: Wisconsin Alumni Research FoundationInventors: Xudong Wang, Weibo Cai, Guang Yao, Lei Kang

Publication number: 20190385121Abstract: Due to the noisy nature of global positioning systems (GPS), tracing a signal from a device of a delivery provider may be inadequate for the task of determining a best dispatch time. However, leveraging motion data from mobile devices provides a more detailed picture of when a delivery provider is on the road, walking, or waiting. Using this data, an example embodiment creates a trip state model that enables segmenting out each stage of a trip. The trip state model enables collection and use of historical data for individual restaurants, which allows a dispatch system to optimize pickup and delivery times for both delivery providers and consumers.Type: ApplicationFiled: June 13, 2019Publication date: December 19, 2019Inventors: Ryan Waliany, Lei Kang, Ernel Murati, Mohammad Shafkat Amin, Nikolaus Paul Volk, Thanh Le Nguyen
