Abstract: One or more computing devices, systems, and/or methods for video encoding are provided. For example, a video file may be segmented into at least a first portion and a second portion. The first portion may be analyzed to determine that the first portion is associated with a first level of complexity, and the second portion may be analyzed to determine that the second portion is associated with a second level of complexity. A first bitrate associated with the first level of complexity may be determined, and a second bitrate associated with the second level of complexity may be determined. The first portion may be encoded at the first bitrate to generate a first encoded portion, and the second portion may be encoded at the second bitrate to generate a second encoded portion. The first encoded portion and the second encoded portion may be assembled to generate an optimized video file.

Abstract: A camera supporting device includes a supporting frame, an outer casing, a camera holding structure, and a linkage mechanism. The outer casing is rotatably connected to the supporting frame. The camera holding structure is rotatably connected to the supporting frame independently of the outer casing. The linkage mechanism incudes a driving part and a driven part kinematically connected to the driving part. The driving part is fixedly connected to the camera holding structure. The driven part is fixedly connected to the outer casing. An image-capturing device can be fixed on the camera holding structure. Through the camera holding structure driving the outer casing through the linkage mechanism, the outer casing can provide a wider angle range available for the image-capturing device to capturing exterior images.

Abstract: The present invention proposes an O-band silicon-based high-speed semiconductor laser diode for optical communication and its manufacturing method, by using different buffer layers to form the growth surface of InP material with low dislocation density; N—InAlGaAs is used instead of conventional N—InAlAs electron-blocking layer in the epi-structure to reduce the barrier for electrons to enter the quantum wells from N-type and lower the threshold; a superlattice structure quantum barrier is used instead of a single layer barrier structure to improve the transport of heavy holes in the quantum wells; and the material structure is adjusted to achieve a reliable O-band high direct modulation speed semiconductor laser diode for optical communication on silicon substrate.

Abstract: Method and Apparatus for access secured electronic data are disclosed. According to one aspect, an off-line access mechanism in a client machine is activated to facilitate those users on the go to access secured electronic data. When a user decides to be away from a network premises or on a business trip, an off-line access request may be generated by the off-line access mechanism and forwarded to a server. In response, the server may grant the off-line access request to the user as well as the client machine from which the user will access the secured electronic data off-line. Depending on implementation, the AC may provide amended or tentative access rules, access privileges or user keys that will automatically expire when a predetermined time ends or become invalid the next time the client machine is connected to the server.

Abstract: Provided are a computer program product, system, and method for generating data structure to maintain error and connection information on components and use the data structure to determine an error correction operation. For each of a plurality of first level components in enclosures connected to second level components, errors at the first level component and a connection between the first level component to one of the second level components are determined and error variables are set to indicate whether an error was reported at the first level component. A data structure is generated indicating connections among the first level components and the second level components. The error variable values and the data structure are used to determine an error correction operation with respect to at least one of the first level component and the connected second level component.
