An advanced multiple-beam GPS receiving system is achieved that is capable of simultaneously tracking multiple GPS satellites independently, detecting multiple interference signals individually, and suppressing directional gain in the antenna pattern of each beam in the interference directions. The GPS receiving system can be used for both planar and non-planar receiving arrays, including arrays that are conformally applied to the surface of a platform such as an aircraft. The GPS receiver combines spatial filtering and acquisition code correlation for enhanced rejection of interfering sources. Enhanced gain in the direction of GPS satellites and the ability to shape the beam patterns to suppress gain in the direction of interfering sources make the GPS receiving system largely insensitive to interfering and jamming signals that plague conventional GPS receivers.

Transactional memory implementations may be extended to include special transaction communicator objects through which concurrent transactions can communicate. Changes by a first transaction to a communicator may be visible to concurrent transactions before the first transaction commits. Although isolation of transactions may be compromised by such communication, the effects of this compromise may be limited by tracking dependencies among transactions, and preventing any transaction from committing unless every transaction whose changes it has observed also commits. For example, mutually dependent or cyclically dependent transactions may commit or abort together. Transactions that do not communicate with each other may remain isolated. The system may provide a communicator-isolating transaction that ensures isolation even for accesses to communicators, which may be implemented using nesting transactions. True (e.g., read-after-write) dependencies, ordering (e.g., write-after-write) dependencies, and / or anti-dependencies (e.g., write-after-read dependencies) may be tracked, and a resulting dependency graph may be perused by the commit protocol.

A multi-grounded neutral electrical isolation system for a personal-communication-system cell site consists of two standard distribution transformers separated by a distance greater than the zone of influence corresponding to the maximum expected ground potential rise at the PCS cell site. The primary winding of the first transformer is connected to the utility's low-voltage distribution system and is grounded through the network's ground. The secondary winding is connected to the primary winding of the second transformer through a high-voltage non-shielded insulated conductor and the frames of the two transformers are kept electrically isolated. The secondary winding of the second transformer energizes the PCS cell site and shares its ground connection, which is also common to the adjacent high-voltage transmission tower. All neutrals are grounded through their respective grounding systems. The second transformer is selected with a basic-insulation-level rating sufficient to withstand the maximum ground potential rise expected to occur at the cell site as a result of a fault or a lightening discharge at the high-voltage transmission tower. By separating the two transformers by a distance at least equal to the zone of influence corresponding to such a GPR, the isolation of the distribution grid from the cell site is ensured. Moreover, the BIL rating of the transformers protects the transmission grid from a sudden potential rise due to a fault in the transformer's insulation.
