An image capturing apparatus capable of guaranteeing the authenticity of a person existing in an image as an object. The image capturing apparatus has an image capturing section that captures an image of an object to generate an image data item. A biometric information acquisition section detects biometric information of the object. A biometric authentication section acquires a biometric authentication result indicating whether or not the detected biometric information matches registered biometric information registered in advance. A hash value generation section generates a hash value from the image data item in a case where the biometric authentication result indicates that the biometric information and the registered biometric information match. The hash value and the image data are recorded in a recording medium. When the image of the object is captured by the image capturing section, biometric information of the object is detected.

Image capturing apparatus that guarantees authenticity of image data, management system, control method, and storage medium

The present disclosure includes systems and methods for reducing rewrite overhead in a sequential access storage system. The method may comprise writing a data set to a sequential access medium using a magnetic head, wherein the data set comprises a plurality of encoded data blocks, classifying each of the plurality of encoded data blocks on the sequential access medium into one of at least three classes of write quality, and rewriting the encoded data blocks in a rewrite area of the sequential access medium based at least in part on the write quality class. In some embodiments, the at least three classes of write quality may comprise a hard rewrite class for which rewrites are necessary to prevent data loss, a soft rewrite class for which rewrites are desirable but not necessary, and a no rewrite class for which no rewrite is needed or desired.

Selective hard and soft rewrites

A first aspect of the present disclosure provides a chair. This chair is provided with a seat portion in which a deformation mode of at least a portion of a seating surface of the seat portion is isolated in such that a target curved surface including a double-curved surface of a prescribed type, relative to a prescribed position, is formed irrespective of the position of the buttocks of a user when the user is seated.

Chair, seat portion, and backrest

Mechanisms are provided to receive encoded header information stored on a tape of a tape drive, wherein the encoded header information has been generated by: generating, for a plurality of tracks of the tape of the tape drive, a header information in a plurality of symbols, wherein the plurality of symbols is comprised of a first set of symbols and a second set of symbols, wherein the first set of symbols include identical information across all tracks of the plurality of tracks, and wherein the second set of symbols are configurable to include different information across all tracks of the plurality of tracks; and modifying, for writing to the tape of the tape drive, the first set of symbols of the plurality of tracks to include parity information corresponding to information included in the second set of symbols of the plurality of tracks. The received encoded header information is decoded.

Header decoding mechanism for tape storage

Aspects of the present disclosure relate to a method of writing a dataset to a tape, the dataset comprising a plurality of sub datasets, each sub dataset including a plurality of headers and a plurality of records. The method includes storing, in each header of each sub dataset, at least a portion of a record range indicator indicating a range of records included in the dataset.

Locating data within tape systems using sub dataset headers

In an approach to adaptive tape calibration criteria based on the number of dead tracks, the number of rewrite occurrences for each dead track on a tape drive is determined. Responsive to detecting that a head is in a dead track state, the number of dead tracks is stored on the tape drive. A calibration threshold is determined, where the calibration threshold includes the number of dead track rewrites and the calibration reference value for a specific tape drive type. Responsive to the number of rewrite occurrences exceeding the calibration threshold while writing a data set, a calibration of the tape drive.

Adaptive tape calibration criteria by number of dead tracks

In a semiconductor-mounting heat dissipation base plate including: an insulating substrate to which a metal circuit layer for mounting a semiconductor chip thereon is fixed; a heat dissipation base formed from the same metal material as the metal circuit layer at a side opposite to the metal circuit layer across the insulating substrate and fixed to the insulating substrate similar to the metal circuit layer; and a strengthening member provided in the heat dissipation base so as to be separated from the insulating substrate, the sizes of crystal grains of a metal structure at a part of the heat dissipation base or the metal circuit layer are reduced by a crystal size reducing material adhered to a mold, thereby preventing an adverse effect of a columnar crystal structure.

Semiconductor-mounting heat dissipation base plate and production method therefor

In an approach to adaptive tape calibration criteria based on the number of stop writes, the number of rewrite occurrences caused by a stop write is determined for each specific tape drive type. Responsive to detecting a stop write during a write operation, the total number of stop writes is stored on the tape drive. A rewrite calibration threshold is determined, where the rewrite calibration threshold includes the total number of stop writes on the tape drive and a calibration reference value for the specific tape drive type. Responsive to the number of rewrite occurrences caused by the stop write exceeding the rewrite calibration threshold while writing a data set on the tape drive, a calibration of the tape drive is performed.

Adaptive tape calibration criteria by number of stop writes

A methodology that enables, for example, tape drive operation at lower SNR and/or reduced rewrite area uses a first threshold T and a second threshold r for a rewrite condition. Codeword interleaves (CWIs) in a data set are written onto a plurality of simultaneously-written parallel tracks of a magnetic recording medium, read back and error correction decoded. A determination is made as to whether at least one of the Cor C' codewords in each decoded CWI contains more byte errors than the second threshold r of the rewrite condition. A number of CWIs in a rewrite buffer are according to the following criteria: b&#x2032;=b&#x2212;T when bis greater than the first threshold T, and b&#x2032;=0 when bis less than or equal to the first threshold T.
