20150046979 | Storage Detection Apparatus, System, and Method - A storage detection apparatus is placed in an operating system in kernel mode; after file information is intercepted and a security level of file content is determined, file content of a high security level is redirected to a storage area of high storage security; the security level of the file content itself is determined and stored, which is transparent to a user, thereby implementing division of security levels for different documents generated by a same application. | 02-12-2015 |
20150134672 | Data Copy Management Apparatus and Data Copy Method Thereof - A data copy management apparatus and a data copy method thereof. The data copy method includes obtaining, using a hash algorithm, hash values of multiple source data blocks obtained by dividing source data; sending the hash values to a target storage side, so that the target storage side determines, based on the received hash values, whether the target storage side directly generates the source data blocks or a source storage side sends the source data blocks to the target storage side; ignoring the source data blocks when a first feedback fed back by the target storage side is received; and sending the source data blocks to the target storage side when a second feedback fed back by the target storage side is received. Thus, a speed of copying a special data block can be improved, saving central processing (CPU) and network resources and reducing copy time. | 05-14-2015 |
20150154087 | DATA PROCESSING DEVICE AND DATA PROCESSING METHOD - Embodiments of the present invention provide a data processing device and a data processing method. In the data processing device and the data processing method provided by the embodiments of the present invention, first data in a memory is written into a first non-volatile storage unit in a log file form, and a log file of the first data written into the first non-volatile storage unit is written into a second non-volatile storage unit. Because a data write speed of the first non-volatile storage unit is higher than a data write speed of the second non-volatile storage unit, fast backup of the data in the memory can be achieved, and when the data in the memory is lost in an abnormal situation, security of the data in the memory can be ensured. | 06-04-2015 |

20150297182 | MECHANICALLY ROTATING INTRAVASCULAR ULTRASOUND PROBE - A mechanically rotating intravascular ultrasound probe relates to the technical field of medical devices, and aims to provide a forward-looking mechanically rotating intravascular ultrasound probe having a small volume, a high image resolution and good imaging stability. The intravascular ultrasound probe includes a catheter, an ultrasonic transducer disposed at a front end of a cavity of the catheter and a driving apparatus that drives the ultrasonic transducer to rotate mechanically. The driving apparatus is a micro motor disposed in the cavity of the catheter, including a rotor and a stator. The ultrasonic transducer is installed on top of the rotor and electrically connected to the rotor, and the rotor is also electrically connected to the stator; the catheter is a magnetic metal tube, and a front end thereof is enclosed by an acoustic window which has a spherical tip and allows ultrasonic waves of the ultrasonic transducer to pass through; the acoustic window is filled with an ionic liquid having a function of a ultrasonic coupling agent. The ultrasound probe solves a problem of rotation torsion of an image when the catheter passes through a lesion with high-grade stenosis or a curved blood vessel section, and achieves forward scanning imaging and side scanning imaging for a blood vessel wall. | 10-22-2015 |
