摘要:
Embodiments of the present invention disclose a processing method for 802.1Q in 802.1Q (QinQ) termination configuration, where the method includes: creating QinQ termination configuration for a user when determining that the user is online; and deleting the QinQ termination configuration of the user when determining that the user is offline. A processing device for QinQ termination configuration is also provided. With the present invention, the dynamic configuration can be implemented for QinQ termination devices, which facilitates user management and effectively improves the resource usage.

A system for managing a reference clock signal includes an XO; a signal buffer coupled to the XO and configured to drive a reference clock signal generated by the XO; and a first IC coupled to the signal buffer. The first IC includes an XO input buffer configured to receive the reference clock signal, to switch between an enabled, operational state and a disabled state, and to have a first operational impedance while in the enabled state; an impedance equivalence circuit configured to be in an enabled, operational state when the XO input buffer is in its disabled state and vice versa and to have a second operational impedance while in the enabled state that is equivalent to the first operational impedance; and a control mechanism configured to switch the XO input buffer and the impedance equivalence circuit between the enabled state and the disabled state.

A febuxostat which purity is not less than 99.0%, method for preparation thereof, and pharmaceutical composition thereof. The method for preparation includes recrystallizing febuxostat in a mixed solvent. The said pharmaceutical composition can be used in manufacture of medicaments for treating diseases associated with hyperuricemia.
摘要:
A portable data processing apparatus includes a storage storing code associated with a computer program that generates at least one of (a) stereoscopic image data and (b) image data associated with images having two groups of primary colors. A keyboard allows a user to input data used by the computer program or entering commands to control execution of the computer program. A built-in digital projector integrated within the portable data processing apparatus projects onto an external display screen at least one of (a) stereoscopic images and (b) images having two groups of primary colors, the built-in digital projector being integrated within the portable data processing apparatus. A microprocessor executes the code and controls the built-in digital projector to project images based on the image data generated by the computer program.
摘要:
An apparatus includes a digital projector capable of projecting two-dimensional (2D) and stereoscopic images, and a controller to control the digital projector to project images based on the image signals. The controller controls the digital projector to switch from projecting stereoscopic images to projecting 2D images based upon a timer signal indicating that the digital projector has continuously projected stereoscopic images for a first preset period of time.

The subject disclosure is directed towards one or more parallel storage components for parallelizing block-level input/output associated with remote file data. Based upon a mapping scheme, the file data is partitioned into a plurality of blocks in which each may be equal in size. A translator component of the parallel storage may determine a mapping between the plurality of blocks and a plurality of storage nodes such that at least a portion of the plurality of blocks is accessible in parallel. Such a mapping, for example, may place each block in a different storage node allowing the plurality of blocks to be retrieved simultaneously and in its entirety.
