Abstract: Methods and means for imaging on paper media are provided. A data file of an image to be printed is analyzed. A pattern for a clear fluid is determined according to the analysis. The pattern of clear fluid is applied to a paper media traveling in a particular direction, wherein the pattern is generally elongated along the direction of travel. The pattern of clear fluid is defined by a maximum width that is generally equal to the maximum width of the image to be formed. One or more colored inks are applied such that the image is formed and is supported by the paper media. The paper media exhibits reduced cockle as a result of the pattern of clear fluid.

Abstract: Systems and methods are disclosed for interaction between different cache coherency protocols. One system may comprise a home node that receives a request for data from a first node in a first cache coherency protocol. A second node provides a conflict response to a request for the data from the home node. The conflict response indicates that an ordering point for the data is migrating according to a second cache coherency protocol, which is different from the first cache coherency protocol.

Abstract: A PKI includes an off-line registration authority that issues a first unsigned certificate to a subject that binds a public key of the subject to long-term identification information related to the subject and maintains a certificate database of unsigned certificates in which it stores the first unsigned certificate An on-line credentials server issues a short-term disposable certificate to the subject that binds the public key of the subject from the first unsigned certificate to the long-term identification information related to the subject from the first unsigned certificate. The credentials server maintains a table that contains entries corresponding to valid unsigned certificates stored in the certificate database. The subject presents the short-term disposable certificate to a verifier for authentication and demonstrates that the subject has knowledge of a private key corresponding to the public key in the short-term disposable certificate.

Abstract: A system and technique for detecting data errors in a memory device. More specifically, data errors in a memory device are detected by initiating an internal READ command or verify operation from a set of logic which is internal to the memory system in which the memory devices reside. Rather than relying on a READ command to be issued from an external device, via a host controller, the verify logic initiates verify routine in response to an event such as an operator instruction, hot-plug operation, or a periodic schedule. By implementing the verify operation, the system does not rely on external READ commands to verify data integrity. The verify routine may rely on typical ECC error logging mechanisms and may be used in a RAID memory architecture. Further, the verify routine may be used in conjunction with other error logging and correction logic, as well as scrubbing logic.

Abstract: A tuned circuit is used to detect wobble clock inversions. The tuned circuit reacts to a wobble inversion with a change in amplitude that may be detected by a threshold detector. A bandpass tuned circuit is used to detect wobble clock inversions. The output of the bandpass tuned circuit is input to a saturating high-gain amplifier such as a comparator. The output of the saturating high-gain amplifier reacts to wobble inversions with a half-cycle that has an increased duration as compared to half-cycles without wobble inversions.

Abstract: A cache coherent distributed shared memory multi-processor computer system is provided with a memory controller which includes a recall unit. The recall unit allows selective forced write-backs of dirty cache lines to the home memory. After a request is posted in the recall unit, a recall (“flush”) command is issued which forces the owner cache to write-back the dirty cache line to be flushed. The memory controller will inform the recall unit as each recall operation is completed. The recall unit operation will be interrupted when all flush requests are completed.

Abstract: A low heat loss and small contact area electrode structure for a phase change media memory device is described. The memory device includes a composite electrode that includes a dielectric mandrel that is connected with a substrate and having a tapered shape that terminates at a vertex. An electrically conductive material conformally covers the dielectric mandrel and terminates at a tip. A first dielectric layer covers all of the composite electrode except an exposed portion of the composite electrode that is adjacent to the tip. A phase change media is in contact with the exposed portion. The exposed portion is only a small percentage of an overall surface area of the composite electrode so that a contact footprint between the exposed portion and the phase change media is small relative to a surface area of the phase change media and Joule heat transfer from the phase change media into the composite electrode is reduced.

Abstract: A system comprising a communications link between processors configured to transmit packets between transmitting and receiving processors. The communications link comprises a conduction path for each bit in the packet and the paths are grouped into separate bundles and routed along different paths. A forwarded clock signal is sent with each bundle. The processors operate with a clock frequency that is roughly three times as fast as the clock frequency of the forwarded clock signal. Data is transmitted on both rising and falling edges of the clock. The receiving processor comprises a recovery circuit to which it pulls the asynchronous data into the processor clock domain. The recovery circuit comprises a delay locked loop circuit configured to create a delayed copy of the clock signal with clock edges that are aligned with the center of the data window for the transmitted data.

Abstract: A system and method for implementing mutual exclusion locks (mutexes) is provided. Mutexes of the present invention designate whether they are to be synchronized using fast nonatomic load/store sequences or, alternatively, expensive atomic hardware instructions. When a requesting thread requests a target mutex, the target mutex is synchronized using the method designated by the target mutex. In some embodiments, the designated synchronization method may be changed to the atomic method when the requesting thread is not the thread associated with the target mutex. In other embodiments, the designated synchronization method may be determined by a heuristic function. For example, the synchronization method may be changed to the atomic method when a mutex request counter, which penalizes thread changes, underflows.
