Patent number: 10902001Abstract: Methods and systems for identifying and displaying present contacts associated with a device's group account are described herein. In some embodiments, a contact list associated with a requesting device may be obtained, and group accounts, and in particular group accounts that have granted communications session privileges to the requesting device's group account, may be determined. Presence information associated with each of the group accounts may be determined so as to identify which of the group accounts are currently “present” (e.g., human presence has been detected proximate to a user's device). These group accounts may be aggregated together, and list metadata may be generated indicating which of the contacts are present, and which are not. The list metadata, as well as list data representing the contact list, may then be provided to the requesting device.Type: GrantFiled: February 27, 2017Date of Patent: January 26, 2021Assignee: Amazon Technologies, Inc.Inventors: Rishi Shankar Rengasamy, Arun Rajendran, Ganesh Basavaraj Mamadapur

Patent number: 10860208Abstract: Systems and methods for using multiple control displays to control displaying applications on a dashboard screen in a vehicle are described. The applications can be non-driving-critical applications running in an operating system installed on a computing device embedded in the vehicle. The computing device is connected to the dashboard screen, a first control display and a second control display. A controlling application in the operating system can populate the first control display and the second control display with different menus, and display one or more of the non-driving-critical applications in a single display area or multiple display areas depending on user inputs from the first control display and the second control display. In an embodiment, the first control display is positioned within a driving wheel of the vehicle and the second control display is positioned between two front seats in the vehicle.Type: GrantFiled: January 4, 2019Date of Patent: December 8, 2020Assignee: BYTON LIMITEDInventors: Shyam Narayan, Kun Ma, Wilson Li, Himanshu Mittal, Ganesh Raman, Arun Rajendran, Neeraja Kukday, Sanjay Madhavarao

Publication number: 20200349943Abstract: Methods and systems for performing contact resolution are described herein. When initiating a communications session using a voice activated electronic device, a contact name may be resolved to determine an appropriate contact with which the communications session may be directed to. Contacts from an individual's contact list may be queried to determine a listing of probable contacts associated with the contact name, and contact identifiers associated with the contact may be determined. Using one or more rules for disambiguating between similar contact names, a single contact may be identified, and a communications session with that contact may be initiated.Type: ApplicationFiled: May 19, 2020Publication date: November 5, 2020Inventors: Someshwaran Elangovan, Aparna Nandyal, Venkatesh Kancharla, Arun Rajendran, Sumedha Arvind Kshirsagar, Christopher Geiger Parker

Patent number: 10662574Abstract: A laundry appliance includes a blower that directs process air along an airflow path. An evaporator dehumidifies the process air and removes condensate from the process air. A heat exchange plate is disposed within the airflow path and supports the evaporator from below and within the airflow path. The heat exchange plate receives the condensate from the process air. A sloped area of the heat exchange plate directs the condensate downward and along the heat exchange plate to a condensate drain, wherein the sloped area includes a directing surface that blocks the process air from pushing the condensate upward and away from the condensate drain.Type: GrantFiled: November 29, 2017Date of Patent: May 26, 2020Assignee: Whirlpool CorporationInventors: Gianluca Bocchino, Arun Rajendran

Patent number: 10619289Abstract: A fluid delivery system for a laundry appliance includes a blower that delivers process air along an airflow path. A drum receives process air to dry laundry. A heat exchanger dehumidifies the process air and removes condensate therefrom. A drain channel receives condensate from the heat exchanger. A pump directs fluid from the drain channel and along a fluid path. The fluid at least partially includes the condensate. A fluid diverter valve receives the fluid from the pump and selectively and delivers the fluid sequentially to a plurality of spray nozzles that direct a flow of the fluid onto a lint filter and toward the drain channel and a fluid outlet.Type: GrantFiled: November 30, 2017Date of Patent: April 14, 2020Assignee: Whirlpool CorporationInventors: Gianluca Bocchino, Arun Rajendran

Publication number: 20200109509Abstract: A laundry appliance includes a rotating drum for processing laundry. A blower directs process air through an airflow path that includes the rotating drum. A heat exchanger is positioned within the airflow path that dehumidifies the process air. A fixedly-secured lint filter captures lint from the process air at a position upstream of the heat exchanger. A fluid spray system has spray nozzles that deliver fluid to a surface of the fixedly-secured lint filter. Each spray nozzle of the plurality of spray nozzles directs captured lint away from the fixedly-secured lint filter.Type: ApplicationFiled: December 10, 2019Publication date: April 9, 2020Applicant: WHIRLPOOL CORPORATIONInventors: Gianluca Bocchino, Arun Rajendran

Publication number: 20200063329Abstract: A fluid flow system for a laundry appliance includes a blower that delivers process air along an airflow path having a heat exchanger. A drain channel receives condensate from the heat exchanger and fluid spray from a spray nozzle for directing lint particles to the drain channel and on to a sump for collecting fluid, including the condensate. A pump seat and a fluid outlet are integrally formed in a sump cover. A pump directs the fluid from the sump to the fluid outlet. A fluid level sensor detects at least minimum and maximum capacities of the fluid in the sump. When the fluid is below the minimum capacity, the pump defines an idle state. When the fluid reaches the minimum capacity, the pump defines an active state. When the fluid exceeds the maximum capacity, the pump directs the fluid to the fluid outlet.Type: ApplicationFiled: October 14, 2019Publication date: February 27, 2020Applicant: WHIRLPOOL CORPORATIONInventors: Gianluca Bocchino, Roy E.
