Abstract: This application provides a task migration system and method. The system includes a first terminal and a second terminal. The second terminal runs a first application. The first terminal opens a recent task interface after receiving a user operation, where the recent task interface includes an identifier of the second terminal; after receiving a user operation performed on the identifier of the second terminal, displays, in the recent task interface, at least one task card corresponding to an application run by the second terminal in the background; and after receiving a user operation performed on a first task card corresponding to the first application, runs the first application, and displays a first user interface of the first application.

Abstract: A transmission system and a transmission method are provided. The transmission system comprises a compressor, an intermediate terminal, and a decompressor. The compressor transmits an initial Internet Protocol package (IP package). The initial IP package comprised an initial forwarding table. The initial forwarding table records at least one candidate context identification (CID). The intermediate terminal receives the IP package and selects the at least one candidate CID different from an intermediate CID recorded in the intermediate terminal, so as to create an intermediate forwarding table. And, the intermediate terminal transmits an intermediate IP package. The decompressor receives the intermediate IP package. The decompressor selects the at least one candidate CID different from a decompressor CID recorded in the decompressor to be a target CID.

Abstract: The present disclosure provides a wireless communication method and a wireless communication system of push-to-talk. The wireless communication system includes a plurality of wireless communication devices to form a mobile ad hoc network. When one wireless communication device operates in an idle state to receive a call invitation via the mobile ad hoc network, it operates into a play state to play audio content of the call invitation. When this wireless communication device operates in the play or talk state to receive another one or more call invitations, it operates into a play and queue state or a talk and queue state to continue an original playing or talking act and to store audio content of said another one or more call invitations later.

Abstract: An optical window structure is disclosed. The optical window structure includes a support layer that has a reinforcement layer and a cushioning layer. In addition, the optical windows structure has a polishing pad which is attached to a top surface of the support layer. Furthermore, the optical window structure has an optical window opening and a shaped optical window. The shaped optical window at least partially protrudes into the optical window opening in the support layer and the polishing pad during operation.

Abstract: A novel colloidal silica slurry including additives for enhancing the removal rate of a metallic workpiece, preventing etch pits, and enhancing smoothness. These additives include HNO.sub.3, H.sub.2 O.sub.2 and Al(NO.sub.3).sub.3. In lieu of colloidal silica, colloidal alumina can be used. The metallic workpiece can be NiP, Ni, Al or other appropriate materials.

Abstract: A memory disk having a central opening and planar sides for receiving magnetic media on both of the sides is bounded by a cylindrical outside diameter peripheral edge and chamfered edges extending between each of the planar sides. The peripheral edge is clamped by a disk processing chuck including a disk retainer mount having a central disk support for mounting a circular disk edge bounding the central opening and a mount cylindrical beveled edge receiving an outside diameter chamfered edge of the disk. A ring in the retainer mount includes a multiplicity of spaced radial fingers extending cylindrically around the ring, each finger having a distal end extending to a first position outboard of the disk peripheral edge. The distal ends are moveable inwardly to a second position by an inflatable bladder acting simultaneously against all the fingers, placing the distal end tips into clamping contact with the disk peripheral edge mounted on the retainer mount.
