Publication number: 20240078854Abstract: The present disclosure relates generally to a vehicle safety system. The vehicle safety system may include operational sensors sensing operational characteristics of a vehicle, environmental sensors sensing environmental characteristics of an environment external to the vehicle, and one or more processors. The operational and environmental sensors may output operational and environmental data based on the operational and environmental characteristics that are sensed by the respective sensors. The processors may examine the operational and environmental data to determine whether the vehicle is in a safe state for an onboard operator of the vehicle to exit the vehicle while avoiding the vehicle rolling away from a stationary state. The processors may examine the operational and environmental data to determine whether the vehicle is not in the safe state and may generate one or more notifications to the operator in response to determining that the vehicle is not in the safe state.Type: ApplicationFiled: June 29, 2023Publication date: March 7, 2024Inventors: Shankar Chandrasekaran, Matthew Price, Satendra Kumar Singh, Rajasekaran Murugesan

Patent number: 11729276Abstract: There are provided systems and methods for a rapid online variable sourcing infrastructure for decision system. Specifically, endpoints may be injected into domain servers serving as a template for sourcing new data variables. When new variables are involved, a first endpoint is injected for registering variables exposed to the domain server, and a second endpoint may be injected to fetch data values at run time, e.g., during the actual decision computation. In this way, data pipeline latency can be avoided during the sourcing process, as the data variables can be sourced from domain servers at run time.Type: GrantFiled: November 10, 2020Date of Patent: August 15, 2023Assignee: PAYPAL, INC.Inventors: Ravi Shankar Chandrasekaran, Dinesh Damodharan

Publication number: 20220407936Abstract: Techniques are disclosed relating to generating real-time suggested actions for a user based on their user profile attributes. In various embodiments, a server system may select, in real-time, a particular action to suggest to a user based on profile attributes associated with a user account of the user. The server system may then provide a message indicative of this particular action to a user device associated with the user. In some embodiments, the server system may then receive an indication that the user has initiated the particular action. In response to this indication, the server system may update the profile attributes associated with the user account to indicate that the user has initiated the particular action. Using these updated profile attributes, the server system may then select, in real-time, an updated action to suggest to the user that is different from the particular action.Type: ApplicationFiled: June 29, 2022Publication date: December 22, 2022Inventors: Sumit Ranjan, Sriram Ramakrishnan, Ravi Shankar Chandrasekaran, Dinesh Damodharan
