摘要:
A shared memory symmetrical processing system including a plurality of nodes each having a system control element for routing internodal communications. A first ring and a second ring interconnect the plurality of nodes, wherein data in said first ring flows in opposite directions with respect to said second ring. A receiver receives a plurality of incoming messages via the first or second ring and merges a plurality of incoming message responses with a local outgoing message response to provide a merged response. Each of the plurality of nodes includes any combination of the following: at least one processor, cache memory, a plurality of I/O adapters, and main memory. The system control element includes a plurality of controllers for maintaining coherency in the system.

Embedded dynamic random access memory (EDRAM) macro disablement in a cache memory includes isolating an EDRAM macro of a cache memory bank, the cache memory bank being divided into at least three rows of a plurality of EDRAM macros, the EDRAM macro being associated with one of the at least three rows, iteratively testing each line of the EDRAM macro, the testing including attempting at least one write operation at each line of the EDRAM macro, determining if an error occurred during the testing, and disabling write operations for an entire row of EDRAM macros associated with the EDRAM macro based on the determining.

A technique for cache coherency is provided. A cache controller selects a first set from multiple sets in a congruence class based on a cache miss for a first transaction, and places a lock on the entire congruence class in which the lock prevents other transactions from accessing the congruence class. The cache controller designates in a cache directory the first set with a marked bit indicating that the first transaction is working on the first set, and the marked bit for the first set prevents the other transactions from accessing the first set within the congruence class. The cache controller removes the lock on the congruence class based on the marked bit being designated for the first set, and resets the marked bit for the first set to an unmarked bit based on the first transaction completing work on the first set in the congruence class.

A vehicle seat latch (24) includes a latch member (40) and a blocking member (70) that each have associated first and second blocking surfaces (80, 82 and 88, 90) for holding the latch member in a latched position with the blocking member in a blocking position. The first blocking surfaces (80 and 88) of the latch member and blocking member have a pressure angle between 4.6 and 6.6 degrees while the second blocking surfaces (82 and 90) have a zero degree pressure angle and are slightly spaced from each other. A deformable blocking portion (84) of the blocking member (70) defines its first blocking surface (88) and is deformed by excessive loading so that the zero degree pressure angle second blocking surfaces (82 and 90) then contact each other to hold the latch member in its latched position.

A leaf and debris catcher for removing leaves and/or debris from a body of water. In one aspect of the invention, the leaf and debris catcher includes a base, a first vertical support member, a horizontal support member, a second vertical support member, and a leaf and debris collection member. In another aspect of the invention, a method is provided for removing leaves from a body of water. The method includes the steps of: providing a leaf and debris collection member; positioning the leaf and debris collection member in a body of water such that the leaf and debris collection member is located in a flow of water; collecting leaves in the leaf and debris collection member; removing the leaf and debris collection member from the flow of water; and removing leaves from the leaf and debris collection member.

Methods, devices, and systems for monitoring heart rate variability (HRV). The HRV monitoring systems and devices are adapted to give immediate feedback to the subject concerning their current condition and any pertinent changes in their condition. The HRV monitoring systems and devices detect, analyze, and assess HRV against a pre-determined application or user need. They also have the ability to provide real time notifications based on the system's assessment of a user's heart HRV and changes in the HRV.

A door wrap including two piece door surface cover connected by a middle jointing section for attachment to a door to protect both sides or top edge of the door on which it is mounted. The door wrap not only protects the door, but also allows the door to be fully functional, such as to be opened, closed or locked. The two-piece door surface covers of the door wrap may be constructed from a piece or pieces of cardboard material while the middle joining section may be made of plastic material. The door wrap may be custom made for uniquely mounted or sized doors, or assembled in standard sizes to fit most doors.

An interface controller that connects devices which read and write the NMEA 0183 sentence data in a RS422 electrical format, to the Ethernet for transmission. NMEA 0183 sentence data is encapsulated and routed to other interface controllers, and/or to user applications operating on computers. A software interface utility designed to operate on the same computer as the users application programs will provide the transparency and the routing/mapping between the Ethernet transmitted NMEA 0183 sentence data and the users application programs communications interface, transparently.

System refresh in a cache memory includes generating a refresh time period (RTIM) pulse at a centralized refresh controller of the cache memory, activating a refresh request at the centralized refresh controller in response to generating the RTIM pulse, the refresh request associated with a single cache memory bank of the cache memory, receiving a refresh grant in response to activating the refresh request, and transmitting the refresh grant to a bank controller, the bank controller associated, and localized, at the single cache memory bank of the cache memory.
