Abstract: A wire is bonded to a target surface using a rotary bond head by positioning a wedge bonding tool of the bond head over the target surface. A camera system is tilted at an oblique angle relative to an arrangement of the bond head to conduct pattern recognition of bonding points on the target surface for determining actual positions of the bonding points and an orientation between the actual positions of first and second bonding points. The bond head is moved to the actual position of the first bonding point and rotated to the determined orientation. Thereafter, the wire is bonded to the target surface at the first bonding point with the bond head.

Abstract: A method and system are provided for managing a multi-threaded process invoking an OpenGL32 command to an OpenGL32 library. Each command requires rendering context as a parameter for access to the library. A manager is provided in conjunction with a table to store rendering context. Each rendering context in the table is assigned an identifier. A thread issuing an OpenGL32 command with an identifier associated with rendering context is passed through to the OpenGL32 library. Similarly, for an OpenGL32 command presented to the manager without an identifier associated therewith, rendering context is created and stored in the table with an associated identifier.
