    摘要： A polycrystalline abrasive composite cutter, including a tool body with a top cutting surface and a flank surface. The composite cutter, joined to a substrate, constitute a shear cutter for a PDC bit, roller-cone bit insert, or other tool that can be highly useful for petroleum drilling or other applications. The body of the polycrystalline abrasive composite cutter includes a plurality of polycrystalline abrasive layers (90) and a plurality of arresting layers (100). The polycrystalline abrasive layers (90) and the arresting layers (100) are arranged to alternate throughout the tool body in a direction normal to the top cutting surface (92) and in a direction normal to a flank surface (94).

    摘要： The current invention discloses method and system to detect remote control and prevent critical application from being peeped at and manipulated. Solution includes remote control detection, remote control blocking and user interaction.When remote access is detected, all suspicious behaviors found during network protocol filtering, session id based detection and remote control behaviour analysis are blocked.Innovative and efficient remote detection methods support user space and kernel space mode, intercept function modules for running applications and services to check and verify. Also new detective methods support network packets filter to judge accurate remote activities.
