Exhaust gas processing device for diesel engine
Provided is an exhaust gas processing device for a diesel engine which can carry out sufficient regeneration processing of a DPF. A DPF regeneration control section continues normal regeneration processing by a DPF regeneration control section when an accelerated regeneration starting operation section does not perform accelerated regeneration starting operation after notification of accelerated regeneration requiring information is started. The DPF regeneration control section prohibits the normal regeneration processing, and an accelerated regeneration re-requirement notification section starts notification of accelerated regeneration re-requiring information, when a PM accumulation amount estimate becomes equal to or higher than an accelerated regeneration re-requirement determination value J4. Thereafter, the regeneration processing of the DPF is not carried out unless the accelerated regeneration starting operation section starts the accelerated regeneration starting operation to cause the DPF regeneration control section to carry out the accelerated regeneration processing by the DPF regeneration section. |

Scanning probe microscope
In the case of measuring a pattern having a steep side wall, a probe adheres to the side wall by the van der Waals forces acting between the probe and the side wall when approaching the pattern side wall, and an error occurs in a measured profile of the side wall portion. When a pattern having a groove width almost equal to a probe diameter is measured, the probe adheres to both side walls, the probe cannot reach the groove bottom, and the groove depth cannot be measured. When the probe adheres to a pattern side wall in measurements of a microscopic high-aspect ratio pattern using an elongated probe, the probe is caused to reach the side wall bottom by detecting the adhesion of the probe to the pattern side wall, and temporarily increasing a contact force between the probe and the sample. Also, by obtaining the data of the amount of torsion of a cantilever with the shape data of the pattern, a profile error of the side wall portion by the adhesion is corrected by the obtained data of the amount of torsion. |

Statistical corner evaluation for complex on-chip variation model
The invention provides a method for performing statistical static timing analysis using a novel on-chip variation model, referred to as Sensitivity-based Complex Statistical On-Chip Variation (SCS-OCV). SCS-OCV introduces complex variation concept to resolve the blocking technical issue of combining local random variations, enabling accurate calculation of statistical variations with correlations, such as common-path pessimism removal (CPPR).

SCS-OCV provides a statistical corner evaluation method for complex random variables that can transform vector-based parametric timing information to the single-value corner-based timing report, and based on the method derives equations to bridge POCV/SSTA with LOCV. This significantly reduces the learning curve and increases the usage of the technology, being more easily adopted by the industry. |

The second macroinstruction instructs the microprocessor to perform an arithmetic/logic operation using the first operand in the second architectural register and a second operand in a third architectural register to generate a result and to load the result back into the first architectural register. An instruction translator simultaneously translates the first and second program-adjacent macroinstructions into a single micro-operation for execution by an execution unit. The single micro-operation instructs the execution unit to perform the arithmetic/logic operation using the first operand in the second architectural register and the second operand in third architectural register to generate the result and to load the result back into the first architectural register. |

Elimination of duplicate objects in storage clusters
Digital objects within a fixed-content storage cluster use a page mapping table and a hash-to-UID table to store a representation of each object. For each object stored within the cluster, a record in the hash-to-UID table stores the object's hash value and its unique identifier (or portions thereof). To detect a duplicate of an object, a portion of its hash value is used as a key into the page mapping table. The page mapping table indicates a node holding a hash-to-UID table indicating currently stored objects in a particular page range. Finding the same hash value but with a different unique identifier in the table indicates that a duplicate of an object exists. Portions of the hash value and unique identifier may be used in the hash-to-UID table. Unneeded duplicate objects are deleted by copying their metadata to a manifest and then redirecting unique identifiers to point at the manifest. |

Using spatial information with device interaction
The amount of resources needed for an electronic device to track and/or interact with a user is reduced by utilizing a predicted relative position of that user. In some embodiments, a full 360° scan is performed using at least one image capture element to locate a primary direction to a user of the device.

Systems and methods for routing cross-channel calls
Activities performed by a client at a site of an organization are monitored and stored in an activity database. A call is thereafter received from the client at a telephone system of the organization, which performs an identification of the client. The identification is provided to a cross-channel router as a request for a prediction on where the call from the client should be routed, and the router indexes into the activity database based on the identification of the client to obtain the monitored activity of the client. The router employs predicting rules and the obtained activity to generate a prediction of client needs, and returns the generated prediction to the telephone-based system, which presents prioritized telephone prompts to the client according to the returned prediction to help in routing the call. |

Enhanced multi user MIMO scheduling
A spatial multiplexing scheduler in, for example, an eNB or other base station, determines rank n precoders for UEs. Each UE reports the preferred precoder from this set of rank n precoders. The preferred precoder results in imbalance in performance over m layers compared to the rest of (n−m) layers. The UEs also report channel quality to the eNB, from which the eNB determines which layer(s) is better for the UE. For example, when n=2 and m=1, the eNB may then select two UEs such that, for the same precoder used by the UEs, the first UE has much higher layer 1 performance than layer 2, and the second UE has much higher layer 2 performance than layer 1. These two UEs may then share the same frequency-time domain resources, with the first UE information sent/received on layer 1, while the second UE information is sent/received on layer 2. |
