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.

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.

In a silicon substrate for a package, a through electrode is provided with which a through hole passing through from a bottom surface of a cavity for accommodating a chip of an electronic device to a back surface of the substrate is filled. An end part of the through electrode in the bottom surface side of the cavity has a connection part to a wiring that forms an electric circuit including the chip of the electronic device. The silicon substrate for a package is characterized in that (1) a thin film wiring is included as the wiring and the connection part is reinforced by a conductor connected to the thin film wiring and/or (2) a wire bonding part is included as the wiring and the connection part is formed by wire bonding the end part of the through electrode in the bottom surface side of the cavity.

The present invention calculates the power consumption of the storage system for each device which supplies power with a storage system, and controls the storage system to keep the power consumption not to exceed the upper limit. In order to achieve this, the power consumption of the chassis configuring the destination storage system is calculated with reference to the number of logical volumes configuring the pool which includes virtual logical volumes, and the logical volumes included in the source storage system are migrated to the virtual logical volumes included in the destination storage system, keeping the power consumption specified in advance per device supplying power to the chassis configuring the destination storage system not to exceed the upper limit value. (Refer to FIG. 27.)
摘要:
There is provided a logical volume management method for storage system. When a logical volume is created on a flash memory drive, a management computer allocates logical volume while flash memory chip border of flash memory drive is taken into account. Specifically, a table for managing a correlation between each parity group and the flash memory chip of the flash memory drive is obtained and the logical volume is allocated in such a manner that a flash memory chip is not shared by a plurality of logical volumes. When complete erasing of logical volume data is performed, the management computer specifies a flash memory chip on which complete data erasing is to be performed, and the storage system completely erases data exclusively on the chip of interest with a use of a function of completely erasing data at a time by chip unit of the flash memory chip (chip erasing).
