Patent number: 5263161Abstract: A data structure has a value field for storing values and a lock field for indicating a lock state of the resource associated with the data structure. This data structure is used to implement a locking protocol amongst multiple processes competing for shared resources. If the lock field is a locked state, the process that locked the lock field has exclusive access to the resource. If, however, the lock field is in an unlocked state, any process may gain access to the resource. The lock field also has deferred states corresponding to the locked and unlocked states wherein multiple requests to lock or unlock the resource may be stored until serviced. The locking protocol is useful in a data processing system having multiple processing elements and utilizes a locking means that includes a local memory controller.Type: GrantFiled: June 11, 1992Date of Patent: November 16, 1993Assignee: Massachusetts Institute of TechnologyInventors: Paul S.

Patent number: 4696603Abstract: A complaint offshore platform in which the primary restoring force to lateral displacement is established by flex piles driven into the seafloor and fixedly secured to the platform legs a preselected distance above the seafloor. The platform includes a substantially rigid space-frame structure extending from the ocean bottom to a position above the ocean surface. A drilling and production deck is secured atop the space-frame structure. Shear piles extend through the base of the space-frame structure to prevent lateral displacement of the base while permitting the space-frame structure to pivot about its base. As the platform sways about its base in response to environmental forces, the flex piles establish a vertical couple at the location at which they are attached to the space frame structure. This couple resists movement of the platform away from a vertical orientation. In the preferred embodiment, the flex piles are secured to the platform at or near one-half the total height of the space-frame structure.Type: GrantFiled: December 5, 1985Date of Patent: September 29, 1987Assignee: Exxon Production Research CompanyInventors: Mark A. Danaczko, Lyle D. Finn, M. Sidney Glasscock, Michael P. Piazza, Kenneth M. Steele, Timothy O. Weaver

Patent number: 4696604Abstract: A pile assembly adapted for use in a compliant piled tower. A plurality of drive piles are driven into the ocean floor in a symetric array about a central, substantially vertical axis. A flex pile is secured to the upper end of each drive pile and extends upward to a preselected elevation above the ocean floor. The longitudinal axes of each drive pile flex pile pair are laterally offset from one another with the flex piles also being arranged in symetric array about the central axis. A tie member is provided to restrain the flex piles from lateral motion relative to one another. The tie member serves to balance the moments established by virtue of the eccentric axes of the flex pile drive pile pairs. The use of eccentric axes in the pile assemblies simplifies driving the drive piles, permits the drive piles to be placed relatively far from one another to minimize pile group effects and permits the flex pile to be designed without being constrained by driving considerations.Type: GrantFiled: August 8, 1986Date of Patent: September 29, 1987Assignee: Exxon Production Research CompanyInventors: Lyle D. Finn, Kenneth M. Steele
