Publication number: 20200051430Abstract: The present disclosure relates to system(s) and method(s) to generate recommendations for traffic management. The system receives historical traffic data associated with each road segment in a target geographical location. Further, the system analyses the historical traffic data to forecast a traffic intensity corresponding to each road segment. The system compares the traffic intensity with a predefined threshold upper value to identify one or more congested road segments. The system further compares the traffic intensity with a predefined threshold lower value to identify one or more uncrowded road segments, when the threshold intensity is less than the predefined threshold upper value. The system identifies a target road segment, from the one or more uncrowded road segments, corresponding to each congested road segment using a routing algorithm. The system further generates one or more recommendations based on the target road segment for traffic management.Type: ApplicationFiled: August 8, 2018Publication date: February 13, 2020Inventors: Gaurav VRATI, Sanjay YADAV

Patent number: 8404502Abstract: The present invention generally relates to organic light emitting diode (OLED) structures and methods for their manufacture. To increase the lifetime of an OLED structure, an encapsulating layer may be deposited over the OLED structure. The encapsulating layer may fully enclose or “encapsulate” the OLED structure. The encapsulating layer may have a substantially planar surface opposite to the interface between the OLED structure and the encapsulating layer. The planar surface permits successive layers to be evenly deposited over the OLED structure. The encapsulating layer reduces any oxygen penetration into the OLED structure and may increase the lifetime of the OLED structure.Type: GrantFiled: May 27, 2011Date of Patent: March 26, 2013Assignee: Applied Materials, Inc.Inventors: Tae K. Won, Jose Manuel Dieguez Campo, John M. White, Sanjay Yadav

Patent number: 7504332Abstract: A method and apparatus for depositing a material layer onto a substrate is described. The method includes delivering a mixture of precursors for the material layer into a process chamber and depositing the material layer on the substrate at low temperature. The material layer can be used as an encapsulating layer for various display applications which require low temperature deposition process due to thermal instability of underlying materials used. In one aspect, the encapsulating layer includes one or more material layers (multilayer) having one or more barrier layer materials and one or more low-dielectric constant materials. The encapsulating layer thus deposited provides reduced surface roughness, improved water-barrier performance, reduce thermal stress, good step coverage, and can be applied to many substrate types and many substrate sizes. Accordingly, the encapsulating layer thus deposited provides good device lifetime for various display devices, such as OLED devices.Type: GrantFiled: January 8, 2007Date of Patent: March 17, 2009Assignee: Applied Materials, Inc.Inventors: Tae Kyung Won, Sanjay Yadav

Publication number: 20080282982Abstract: The present invention generally relates to an inductively coupled plasma apparatus. When depositing utilizing a plasma generated from a showerhead, the plasma may not be evenly distributed to the edge of the substrate. By inductively coupling plasma to the chamber in an area corresponding to the chamber walls, the plasma distribution within the chamber may be evenly distributed and deposition upon the substrate may be substantially even. By vaporizing the processing gas prior to entry into the processing chamber, the plasma may also be even and thus contribute to an even deposition on the substrate.Type: ApplicationFiled: February 28, 2008Publication date: November 20, 2008Inventors: John M. White, Sanjay Yadav, Qunhua Wang, Soo Young Choi, Weijie Wang
