Patent number: 11767408Abstract: Methods of depolymerizing polyolefin-based material into useful petrochemical products using supported metal oxides and heat are described. The supported metal oxides improve the depolymerization reaction by decreasing the half time for the depolymerization, which results in a higher depolymerization rate and a shorter residence time in the depolymerization unit, allowing for a predictable depolymerization reaction, and decreasing the branching or aromatic formations in the product.Type: GrantFiled: October 29, 2021Date of Patent: September 26, 2023Assignee: Basell Poliolefine Italia S.r.l.Inventors: Sandor Nagy, Daniel F. White, Christopher D. Smith, Xueyong Yang, David L. Ramage

Patent number: 11501009Abstract: An electronic privacy apparatus, for selectively blocking transmission of data from a camera, includes a camera, a first processor, a switch, and a second processor. The first processor is connected to the camera and receives image data from the camera. The switch is connected to the first processor. The second processor is configured to execute an operating system. The first processor implements a transmission state where the first processor transmits the image data to the second processor. The first processor also implements a privacy state where the first processor transmits blank data to the second processor. Based on user input, the switch selects either the transmission state or the privacy state and transmits a signal to the first processor indicating the user input.Type: GrantFiled: September 30, 2021Date of Patent: November 15, 2022Assignee: Lenovo (Singapore) Pte. Ltd.Inventors: Xueyong Yang, Hiroshi Nakagawa, Kazuhiro Kosugi, Yasumichi Tsukamoto
