  • Patent number: 9652142
    Abstract: A first device such as a portable computing device can be configured to act as a text-entry device (in a text-entry mode) and a cursor control device (in a cursor control mode) for a second device. The first device can include a touch-sensitive display capable of receiving text inputs and cursor inputs for controlling the display of a second device which is communicatively coupled to the first device. The first device can be configured such that selection of certain items displayed by the second device can cause the first device to switch from a text-entry mode to a cursor control mode. The first device can be configured such that rotation of the device between a landscape orientation and a portrait orientation causes the device to switch between modes. The first device can be configured such that sideways movement of the device causes the device to switch between modes.

  • Patent number: 9349120
    Abstract: Methods, systems, and computer programming products are provided for silencing message threads. Incoming messages related to the same matter are grouped into one or more message threads. A user can select to silence a message thread. Once a message thread has been silenced, the user will no longer receive notifications of new messages added to the thread.

  • Patent number: 9164649
    Abstract: An electronic computing device can be configured to act as a text-entry device and a cursor control device for a second device. The first device can include a touch-sensitive display capable of receiving text inputs and cursor inputs for controlling operations performed on the second device which is communicatively coupled to the first device. The first device can be configured such that selection of a field displayed by the second device can cause information such as text from a focus field to be displayed by the first device. The second device can be configured to send information pertaining to the focus field to the first device. The information can include a warning that the maximum length of input for the focus field has been, or is about to be, exceeded.

  • Patent number: 9105023
    Abstract: Embodiments of the systems, devices, and methods described herein generally facilitate transmission and reception of activation data for use in activating a mobile device to operate with a server. In accordance with one example embodiment, an activation barcode is received from a server by reading an image comprising the activation barcode via a computing device, wherein the image is displayed on a display associated with the computing device, and wherein the activation barcode encodes activation data comprising an activation password. The activation barcode is decoded at the mobile device to obtain the activation password, and an authentication is performed using the activation password after a device activation request is transmitted to the server, wherein the mobile device is activated to operate with the server if the authentication is successful.

  • Patent number: 8983458
    Abstract: A mobile communication device maintains a stored list of a plurality of carrier identifications, where each carrier identification is stored in association with one of a plurality of country codes. The mobile device is also associated with a home wireless carrier that is identifiable by a home carrier identification stored in its memory. The mobile device reads the home carrier identification from the memory, and selects one of the plurality of country codes that is stored in association with the home carrier identification. During operation, the mobile device reads a specified domain name in response to a user-initiated request made via a Web browser or search application. Then, the mobile device produces a Hypertext Transfer Protocol (HTTP) request with a Uniform Resource Locator (URL) corresponding to a specified domain name and a country code parameter which includes the selected country code. The HTTP request with the URL is submitted via the wireless communication network.
