Abstract: Various embodiments that relate to local communication are discussed. A radio from one geographical area can enter a communication environment of a different geographical area. However, if the radio still functions consistent with the previous geographical area, then the radio will not blend into the new geographical area. Therefore, the radio can alter operational characteristics when entering the new geographical area such that the radio blends into the new geographical area from a radio frequency perspective.

Abstract: A communications satellite system that provides one terabit/second throughput utilizing passive optical beamforming networks. An onboard telescope couples uplinked optical beams into an onboard optical signal processing system via an optical waveguide. The passive optical signal processing system comprises an optical demultiplexer, a multiplicity of single-sideband filters, and a multiplicity of optical beamforming networks. The optical beamforming networks and the SSB filters may comprise optical ring resonators. The output of the optical signal processing system is converted into electrical signals which are sent to a phased-array transmit antenna. The user links are in the radio-frequency (RF) domain.

Abstract: Provided herein are systems and methods for establishing secure communications and connectivity between agents (client, user, or service) over any physical network topology. The system allows clients (client, user, or service agents) to connect to services in a secure manner reducing risks from third party trust attacks, denial-of-service, and anonymous attacks (either zero-day or using known vulnerabilities) while simultaneously improving the performance of the connectivity.

Abstract: A user device transmits a login request. A provider server, receives a random number from and transmits other information to an authentication server. The provider server transmits the random number to the device. The random number is transferred to a second user device, which transmits it to the authentication server. The authentication server transmits provider authentication policy requirements and further transmits the other information to the second device. The second device transmits user validation information to the authentication server. The authentication server determines that the transmitted validation information corresponds to the service provider authentication policy requirements, compares the validation information with stored validation information for the user to authenticate the user. The second device transmits a message, including the random number and the other information, signed with a user credential to the authentication server.

Abstract: A graphical user interface made up of icons representing individual files and collectively forming the shape of a “v” is described along with methods of using and creating the graphical user interface. The v-shaped interface is useful to display detailed information about many of the items in a list and facilitates manipulation of list order and selection of the active file in the list. The interface further permits the use of a representative icon associated with the list as a whole. Manipulation of the representative icon can cause modification or replacement of the entire playlist represented by the icon.

Abstract: An authentication server transmits a random number to and receives a other information from a service provider. Later, the first random number is received from a requester and a provider identifier, the received other information and provider authentication policy requirements are transmitted to the requester. A user identifier and validation information are received from the requester. The received validation information is determined to correspond to the provider authentication policy requirements, and compared with stored user validation information associated with the received user identifier to authenticate the requester. A message, including both the random number and other information, signed with a credential of the requesting user is received and transmitted to the first provider.

Abstract: A network user is authenticated to another network entity by using a first program to receive user input validation information, and store a user credential. A second program receives information, such as a random number, from the other entity. The first program receives an input transferring the information to it, transmits the information to the authentication server, and receives an identifier of the other entity, other information, and authentication policy requirements from the authentication server. It then transmits the input validation information corresponding to the received authentication policy requirements to the authentication server, and in response receives a request for a user credential. It signs a message, including the transferred information and the received other information, with the stored user credential, and transmits the signed message to the authentication server to authenticate the user.

Abstract: Background frames can be completed from a collection of frames having foreground objects that are partially obscuring the pixels comprising the background. The special offset of a pixel represented across a collection of frames can be determined based on camera movement data. By determining the relative offset of a pixel represented in a first frame from the same pixel in other frames, pixel values representing a background object can be accumulated to derive a completed background frame.

Abstract: Among other things, methods, systems and computer program products are disclosed for manipulating media. In one aspect, a first set of media item images is displayed in a first region of a display screen. The media item images are moved about a predetermined path within the first region in response to a received input. A second set of media item images is displayed in a second region of the display screen where the second set of media item images are associated with an indicated media item image displayed in the first region. At least one of the media item images in the second set of media item images displayed in the second region is different from the indicated media item image.
