Abstract:

An improved adjustable golf tee comprises a tubular housing, an inner member slideably retained within the housing, and a removable retaining plug inserted into the housing. The tubular housing has an upper end, and a lower end fixed to a base. The lower end of the housing has an opening therein that is suitably generally rectangular in cross section and is beveled outwardly on opposed sides. The inner member has an upper end for supporting a golf ball, a body and a lower portion slideably retained at respective desired positions within the tubular housing. The lower portion of the inner member has two flexible legs that are extendable through the lower opening of the housing. Once the inner member is slid into the desired position, relative to the housing, the legs are extended outwardly along the beveled sides of the lower opening. The removable plug is inserted between the flexible legs of the inner member and wedged into the external lower opening, to fix the flexible legs against the lower end of the housing, to retain the inner member at the desired position.

Abstract:

Methods and apparatus for managing stack data in multi-core processors having scratchpad memory or limited local memory. In one embodiment, stack data management calls are inserted into software in accordance with an integer linear programming formulation and a smart stack data management heuristic. In another embodiment, stack management and pointer management functions are inserted before and after function calls and pointer references, respectively. The calls may be inserted in an automated fashion by a compiler utilizing an optimized stack data management runtime library.
