Patent number: 11184660Abstract: Devices and methods are provided for dynamically switching states of remote control devices. A remote control device may receive voice data from a user, send the voice data to another device which may pass the voice signals to a server. The server may determine instructions associated with responding to the voice signals and send the instructions to the other device, which may convert the instructions to remote control commands. The other device may send the commands along with state information to the remote control device, allowing the remote control device to emit commands determined by the other device and to map other command signals to possible inputs which the remote control device may receive.Type: GrantFiled: September 27, 2018Date of Patent: November 23, 2021Assignee: Amazon Technologies, Inc.Inventors: Brian Ewanchuk, Hongmei Dilip Li, Bernardo De Carvalho e Silva, Balsa Laban, Vijai Rajagopal, Chang Hwa Rob Yang

Patent number: 8556303Abstract: An apparatus secures a cover onto a housing of a portable electronic device. The apparatus has a first latch that is pivotally connected to the cover by a first hinge, so that in a first rotational position, the first latch contacts a first catch on the housing and in a second rotational position, the first latch is remote from the first catch. A second latch assembly has a second latch that is pivotally connected to the cover by a second hinge, so that in one rotational position, the second latch contacts a second catch on the housing and in another rotational position, the second latch is remote from the second catch. By squeezing the first and second latches between two fingers, a user is able to disengage those latches from the catches and remove the cover from the housing.Type: GrantFiled: August 19, 2009Date of Patent: October 15, 2013Assignee: BlackBerry LimitedInventors: Vijai Rajagopal, James Carl Infanti, Timothy Herbert Kyowski

Patent number: 8507820Abstract: A mobile electronic device has a dome switch assembly secured to the housing of the device, over a recess formed in the housing of device. The dome switch assembly has a substrate with a vent hole communicating between the recess of the housing and the space comprised between the substrate and a dome actuation portion of the dome switch assembly. Upon actuation of the dome switch assembly, air present between the dome actuation portion and the substrate flows into the recess of the housing.Type: GrantFiled: November 25, 2011Date of Patent: August 13, 2013Assignee: Research In Motion LimitedInventors: Chao Chen, Vijai Rajagopal

Patent number: 8378240Abstract: A switch assembly is provided to actuate a pair of switches using a single push key, e.g. for a camera that utilizes a first switch to activate an image focusing function and a second switch to activate a camera shutter. The switch assembly comprises a contact pad switch and a dome switch that are located laterally to one another. When the push key receives a first downward force, only the contact pad switch becomes activated and a first electric circuit is completed. When the push key receives a second downward force that is greater than the first force, the dome switch collapses and a second electric circuit is completed.Type: GrantFiled: June 21, 2012Date of Patent: February 19, 2013Assignee: Research In Motion LimitedInventors: Vijai Rajagopal, James Infanti, Firmansyah Sulem, Timothy Kyowski

Patent number: 8297666Abstract: An apparatus for securing a cover over an opening defined in a housing of a portable electronic device includes a pair of latches along opposite edges of the cover. Each latch assembly has a cap affixed to the cover and partially housing a latch that is slideable therein. Each latch is biased by a separate spring into a first position, at which a tab on that latch projects from the cap and engages the housing. An actuator on each latch extends outside the respective cap for engagement by a user to slide the latch into a second position in which the associated tab is retracted from engaging the housing.Type: GrantFiled: March 27, 2009Date of Patent: October 30, 2012Assignee: Research In Motion LimitedInventors: Vijai Rajagopal, James Carl Infanti, Timothy Herbert Kyowski

Patent number: 8058571Abstract: A switch assembly is provided to actuate a pair of switches using a single key cap, e.g. for a camera that utilizes a first switch to activate an image focusing function and a second switch to activate a camera shutter. The switch assembly comprises an inner switch and an outer switch, wherein the outer switch partially or completely surrounds the perimeter of the inner switch. The outer switch comprises an upper conductive surface and a lower conductive surface that, when in contact, electrically couples two terminals for closing a circuit. The inner switch comprises an actuator and a dome switch. When the key cap receives a first downward force, only the outer switch becomes activated and a first electric circuit is completed. When the key cap receives a second downward force that is greater than the first force, the dome switch collapses and a second electric circuit is completed.Type: GrantFiled: February 25, 2009Date of Patent: November 15, 2011Assignee: Research In Motion LimitedInventors: Vijai Rajagopal, Firmansyah Sulem, Timothy Kyowski, James Infanti
