Patent number: 9595240Abstract: Techniques for adjusting a brightness of a front that lights a display of an electronic device in response to determining that the display is going to perform an update. Typically, page updates on certain types of displays, such as electronic paper displays, result in a relatively large but rapid change in brightness. Therefore, by increasing the brightness during the relatively dark portion of the update (e.g., when some, a majority, or all of the pixels are in the black state) and then decreasing the brightness back to its initial state upon completion of the update, the overall brightness perceived by the user remains more uniform. Increasing the uniformity of this perceived brightness in turn decreases the jarring affect of the flashing update and increases the experience of the user.Type: GrantFiled: November 25, 2013Date of Patent: March 14, 2017Assignee: Amazon Technologies, Inc.Inventors: Siddharth Gupta, Scott Michael Dylewski

Patent number: 9564104Abstract: Techniques are presented for adjusting a brightness of a front light that illuminates a display of an electronic device. Typically, page updates on certain types of displays, such as electronic paper displays, result in a relatively large but rapid change in brightness. Therefore, by adjusting the brightness of the front light during the update (e.g., when some, a majority, or all of the pixels are in the white state) and then adjusting the brightness back to another state upon or near completion of the update, the overall brightness perceived by the user remains more uniform. Increasing the uniformity of this perceived brightness in turn decreases the jarring effect of an update and increases the experience of the user.Type: GrantFiled: May 18, 2015Date of Patent: February 7, 2017Assignee: Amazon Technologies, Inc.Inventors: Herve Jacques Clement Letourneur, Siddharth Gupta

Publication number: 20160261457Abstract: Homes, enterprise establishments, and other facilities often have routing devices that route traffic to locally connected client devices. A routing device may be connected to an external network (e.g., the internet) through a bridging device, such as an outdoor unit that receives network connectivity through a cellular backhaul connection. If the bridging device's backhaul connection temporarily fails (e.g., due to radio link failure), a public IP address associated with the bridging device and the routing device may change upon recovery of the backhaul connection. If the routing device is not aware of the changed public IP address, subsequent communications between the routing device and the external network may fail. Disclosed are systems and methods for recovering from connectivity failure when using bridging devices to provide network connectivity.Type: ApplicationFiled: March 3, 2015Publication date: September 8, 2016Inventors: Siddharth Gupta, Rohit Tripathi, Tyler Byron Wear, Ady Abraham, Elena Salman

Publication number: 20160192403Abstract: A method, an apparatus, and a computer program product for communication in a network. The apparatus sends a multicast message to a network device. The multicast message facilitates discovery of an unknown IP address of the network device. The apparatus determines whether a first response message is received from the network device in response to the multicast message and determines the IP address of the network device from the first response message when the first response message is received from the network device. The apparatus establishes a secure connection with the network device using the determined IP address. The apparatus sends a link status check message to the network device to detect a failed end-to-end link between the apparatus and the network device.Type: ApplicationFiled: December 30, 2014Publication date: June 30, 2016Inventors: Siddharth GUPTA, Rohit TRIPATHI, Kuo-Chun LEE, Sivaramakrishna VEEREPALLI, Tyler Byron WEAR, Vaibhav KUMAR

Publication number: 20160182683Abstract: Homes, enterprises, and other facilities often have routers that receive internet connectivity through wired remote network connections, and this connectivity is provided to locally connected client devices. Smart phones and other wireless devices can serve as mobile access points that receive internet connectivity through different remote network connections (e.g., cellular networks). The mobile access points may also service client devices that may be different from those serviced by the routers. When a mobile access point is placed in a facility having a router, the local networks of the mobile access point and the router may be merged. Disclosed are systems and methods for dynamically selecting from multiple host devices (e.g., the router and the mobile access point) to provide internet connectivity for merged networks.Type: ApplicationFiled: December 22, 2014Publication date: June 23, 2016Inventors: Tyler Byron Wear, Gaurav Gopal Kathuria, Rohit Tripathi, Siddharth Gupta, Chaitanya Pratapa

Patent number: 9299320Abstract: Techniques for providing visual feedback on a display of an electronic device by sequentially and/or independently controlling the illumination of the lighting output by the display. In some implementations, the techniques may be employed following an interaction with the device having one or more light source controllers instructing one or more light sources, such as Light Emitting Diodes (LEDs), in a lighting apparatus, such as for a display which renders content on the device. For instance, a lightguide of the lighting apparatus may sequentially receive light from the one or more light sources as directed by the one or more light source controllers and may direct the light to provide illumination for a display. In some cases, the display may be a reflective display that is front-lit by the lighting apparatus. In other cases, the display may be a backlit display that is backlit by the lighting apparatus.Type: GrantFiled: February 20, 2014Date of Patent: March 29, 2016Assignee: Amazon Technologies, Inc.Inventor: Siddharth Gupta

Patent number: 9097825Abstract: A front light component for electronic devices that include displays for rendering content using a light guide to control illumination for a front light display. A high reflectivity “white” tape is used under and adjacent to the light guide to improve overall uniformity of the light beams. The high reflectivity tape may also be selected to be of a controlled white hue to compensate for variances in color of Light Emitting Diodes (LEDs) where the LED color is slightly off from ideal white. In this way the complementary color of the high reflectivity tape with the color of the LED will cause the output spectrum to be uniform and white. This disclosure also describes techniques for assembling electronic devices in a component stack to provide enhanced display uniformity and improved reading experience.Type: GrantFiled: June 24, 2013Date of Patent: August 4, 2015Assignee: Amazon Technologies, Inc.Inventors: Siddharth Gupta, Gregory Turner Witmer

Patent number: 8693267Abstract: A system and a method to improve signal synchronization in a plurality of signal paths traversing multiple voltage domains. According to an embodiment of the present disclosure a memory arrangement is preferred for signal synchronization. All read/write and clocks signals and other control signals are driven to periphery supply (Vp) levels, except wordline (WL[i]) signals which are driven at core supply (Vc) level. By doing so, lower average and peak current consumption associated with core supply (Vc) is achieved with constant delays and maintaining required signal synchronization in the signal paths traversing multiple voltage domains.Type: GrantFiled: December 23, 2009Date of Patent: April 8, 2014Assignee: STMicroelectronics International N.V.Inventors: Siddharth Gupta, Rakesh Kumar Sinha, Vamsi Krishna Gullapalli, Dibya Dipti
