摘要:
In a storage system in which computers are connected via a network, in order to avoid a state where communication quality is degraded due to poor performance of an apparatus constituting the network, for a transfer data amount, an amount of data sent out from a storage apparatus is suppressed. Moreover, the storage apparatus inhibits a read-ahead process, in accordance with the suppression of the sending out of the data. Furthermore, proper load allocation is realized by migrating a logical storage unit provided by the storage, to another network interface or a second storage apparatus, without changing a configuration of the network.

A wiring board adapted for mounting an electronic component has the form of a structure in which a plurality of wiring layers are stacked one on top of another with an insulating layer interposed therebetween and are interconnected through via holes formed in the insulating layers, respectively. A plurality of openings are formed through the structure in a region where a wiring is not formed, extending through the structure in a thickness direction thereof. Further, solder resist layers are formed on the outermost wiring layers, respectively, and exposing pad portions defined in desired locations in the outermost wiring layers.

A shield device for a resonance type contactless power transmission system that reduces adverse influence on power transmission efficiency without unnecessarily increasing space for installing the shield device is provided. A shield device of the resonance type contactless power transmission system includes cylindrical shield members, which are provided in a power supply unit and a power receiving unit, respectively. The distance between the bottom of the shield member provided in the power supply unit and the primary-side resonance coil and the distance between the bottom of the shield member provided in the power receiving unit and the secondary-side resonance coil are both set to be greater than a distance between the primary-side resonance coil and the secondary-side resonance coil that allows power transmission at the maximum efficiency from the power supply unit to the power receiving unit.

A three-dimensional (3D) location of a reflection point of a ray between a point in a scene (PS) and a center of projection (COP) of a camera of a catadioptric system is determined. The catadioptric system is non-central and includes the camera and a reflector, wherein a surface of the reflector is a quadric surface rotationally symmetric around an axis of symmetry. The 3D location of the reflection point is determined based on a law of reflection, an equation of the reflector, and an equation describing a reflection plane defined by the COP, the PS, and a point of intersection of a normal to the reflector at the reflection point with the axis of symmetry.

Embodiment of invention discloses a system and a method for determining a three-dimensional (3D) location of a folding point of a ray between a point in a scene (PS) and a center of projection (COP) of a camera of a catadioptric system. One embodiment maps the catadioptric system, including 3D locations of the PS and the COP on a two-dimensional (2D) plane defined by an axis of symmetry of a folding optical element and the PS to produce a conic and 2D locations of the PS and COP on the 2D plane, and determines a 2D location of the folding point on the 2D plane based on the conic, the 2D locations of the PS and the COP. Next, the embodiment determines the 3D location of the folding point from the 2D location of the folding point on the 2D plane.

Embodiments of the invention disclose a system and a method for determining a pose of a probe relative to an object by probing the object with the probe, comprising steps of: determining a probability of the pose using Rao-Blackwellized particle filtering, wherein a probability of a location of the pose is represented by a location of each particle, and a probability of an orientation of the pose is represented by a Gaussian distribution over orientation of each particle conditioned on the location of the particle, wherein the determining is performed for each subsequent probing until the probability of the pose concentrates around a particular pose; and estimating the pose of the probe relative to the object based on the particular pose.
摘要:
Log manipulation by a first administrator is prevented so that the reliability of system auditing can be improved.After receiving a service start request from a management computer, a storage subsystem creates a first resource group regarding which access by a host computer is permitted, and also creates a second resource group regarding which access by the management computer is permitted. The storage subsystem further creates a data storage area, to which data is to be written by the host computer, and makes the data storage area belong to the first resource group, while it also creates a log storage area, in which log information indicating past operation performed on the data storage area by the host computer is to be recorded, and makes the log storage area belong to the second resource group.
