摘要:
A method of joining a first component and a second component is provided. The first component has a surface that comprises at least about 75% by volume of a refractory metal. The second component has a coefficient of thermal expansion greater than a coefficient of thermal expansion of the first component. The method includes disposing a coating on the surface of the first component. The coating includes an adhesion layer and a wetting layer disposed over the adhesion layer. The method further includes disposing a bonding material between the first and second components and joining them. The bonding material has a melting temperature lower than a melting temperature of the second component. An article made using the method is also presented.

Methods and devices are provided that use lower-layer signalling, for example Layer 1 (L1) and/or Layer 2 (L2), as a part of mobility beam management. A method for performing inter-cell mobility management may include receiving, by a user equipment (UE) from a network, higher-layer signaling that includes configuration information for a plurality of mobility beam management reference signals (MBM-RSs) enabling the UE to measure MBM-RSs transmitted by at least one base station in the network. In addition the UE may receive from the network, lower-layer signaling include additional information relating to monitoring for a mobility beam MBM event.

Preferred systems and methods provide a personal channel for broadcasting personal content to televisions over a network, such as a fiber optic access network. A service provider assigns a personal channel identifier to a broadcaster. This identifier allows viewers to tune to the personal channel. The broadcaster sends personal content to the service provider together with a list of authorized viewers for that personal content. The service provider stores the personal content and makes it available as specified by the subscriber for viewing. When requested, the service provider sends the personal content to the specified set top boxes on the assigned personal channel identifier. By tuning the set top box to the broadcaster's channel, viewers may view the personal content on television as though it were broadcast from any network television station.

An approach is provided for faceted browsing of video assets. A metadata file is parsed to categorize and rank attributes corresponding to a video asset, wherein the ranked attributes are based on a criterion. A set-top box provides attribute browsing to determine selection of the video asset.
摘要:
A method for dispersing nanotubes, comprising forming a nanocomposite solution with associated nanotubes and nanoplatelets, mixing a surfactant to the nanocomposite solution, separating the nanocomposite in solution, wherein the nanotubes remain suspended in the surfactant solution, and isolating the nanotubes in solution. In certain instances, the method further comprises functionalizing the nanotubes in solution.
摘要:
Systems and methods are provided for enhanced television services such as an interactive audio programming guide for a television. Users may use an input device, such as a remote control, to select display objects displayed on an output device, such as a television, as part of an interactive programming guide. An IPG module on a network terminal, such as a set top box, may determine whether the display object requires an audio representation. If an audio representation is required, the set top box may transmit an audio representation of the display object to the television to be played for the user.
摘要:
An indirectly heated cathode assembly is presented. The indirectly heated cathode assembly includes at least one electron source for generating a first electron beam, an emitter for producing a second electron beam when heated by the first electron beam and a focusing electrode for controlling, and directing the first electron beam towards the emitter.
