A RAID controller uses a method to identify a storage device of a redundant array of storage devices that is returning corrupt data to the RAID controller. The method includes reading data from a location of each storage device in the redundant array a first time, and detecting that at least one storage device returned corrupt data. In response to detecting corrupt data, steps are performed for each storage device in the redundant array. The steps include reading data from the location of the storage device a second time without writing to the location in between the first and second reads, comparing the data read the first and second times, and identifying the storage device as a failing storage device if the compared data has a miscompare. Finally, the method includes updating the location of each storage device to a new location and repeating the steps for the new location.

A biometrics authentication device identifies characteristics of the body from captured images of the body and performs individual authentication. The device guides a user, at the time of verification, to the image capture state at the time of registration of biometrics characteristic data. At the time of registration of biometrics characteristic data, body image capture state data is extracted from an image captured by an image capture unit and is registered in a storage unit, and at the time of verification the registered image capture state data is read from the storage unit and is compared with image capture state data extracted at the time of verification, and guidance of the body is provided. Alternatively, an outline of the body at the time of registration, taken from image capture state data at the time of registration, is displayed.

An electronic flash-memory card has additional pipes for commands and status messages so that data pipes are not clogged with commands and status messages, allowing for a higher data throughput. The command and status pipes are activated when a UAS/BOT detector detects that a host is using a USB-Attached-SCSI (UAS) mode rather than a Bulk-Only-Transfer (BOT) mode. The host can send additional commands and data without waiting for completion of a prior command when operating in UAS mode but not while operating in BOT mode. A command queue (CQ) in the device re-orders commands for accessing flash memory and merges data in a RAM buffer. Smaller 1 KB USB packets in the data pipes are merged into larger 8 KB payloads in the RAM buffer, allowing for more efficient flash access.

Improved convergence in the volume-integral method (VIM) of calculating electromagnetic scattering properties of a structure is achieved by numerically solving a volume integral equation for a vector field, F, rather than the electric field, E. The vector field, F, may be related to the electric field, E, by a change of basis, and may be continuous at material boundaries where the electric field, E, has discontinuities. Convolutions of the vector field, F, are performed using convolution operators according the finite Laurent rule (that operate according to a finite discrete convolution), which allow for efficient matrix-vector products via 1D and/or 2D FFTs (Fast Fourier Transforms). An invertible convolution-and-change-of-basis operator, C, is configured to transform the vector field, F, to the electric field, E, by performing a change of basis according to material and geometric properties of the periodic structure. After solving the volume integral for the vector field, F, an additional post-processing step may be used to obtain the electric field, E, from the vector field, F. The vector field, F, may be constructed from a combination of field components of the electric field, E, and the electric flux density, D, by using a normal-vector field, n, to filter out continuous components.

A processor having a reduction unit that sums m input operands plus an accumulator value, with the option of saturating after each addition or wrapping around the result of each addition.

The reduction unit can be used in conjunction with m parallel multipliers to quickly perform dot products and other vector operations with either saturating or wrap-around arithmetic.
