20090013163METHOD AND SYSTEM FOR MONITORING AND ADAPTIVELY PRE-LOADING CRUCIAL DYNAMIC LINK LIBRARIES - The invention provides a system and method for adaptively loading frequently loaded dynamic link libraries. The system comprises: a monitor for monitoring loading events of dynamic link libraries while an operating system is running, and logging a name and related loading information of the corresponding dynamic link library into a log file in response to the loading events; and an invoker for automatically loading at least one of the most frequently loaded dynamic link libraries logged in the log file upon a subsequent startup of the operating system. By using the system and method, startup performance of the most frequently used applications can be greatly improved.01-08-2009
20090157741DATA OBJECT COPY/PASTE TRANSFER METHOD AND APPARATUS - The present invention provides a solution of transferring a data object between files through copy/paste, in which not only the filtered data object which is adapted to the format and/or function of a destination file is explicitly written to the destination file, but also the original data object information is implicitly written to the destination file, and the map relationship between them is established, so that the whole original information of the transferred data object is reserved during the transfer between files. In subsequent copy/paste operations, the user may choose to use the original data object corresponding to the data object in the transfer of the data object or not based on the actual situation and particular needs, so that the problem of information loss in the process of transferring a data object between files through copy/paste operation is solved effectively.06-18-2009
20110029625METHOD AND SYSTEM FOR PROCESSING EMAIL ATTACHMENTS - The present invention provides a method and system for processing email attachments. The method includes determining that a local file is attached as an email attachment in the email; creating a corresponding relationship record of the email attachment and the local file; determining that the email attachment is modified; and replacing the local file with the modified email attachment according to the corresponding relationship record automatically.02-03-2011

20100171500DEDICATED SYSTEM FOR MSK JOINT IMAGING - A system and method are presented that facilitate imaging of the joints of the upper and lower extremities including, for example, the hip and shoulder as well as sections of the spine, among others. One embodiment of the invention includes a short bore cylindrical magnet with an imaging volume smaller than that of a comparable whole body system, an articulated table that allows placement of the joint to be imaged in the center of the magnet homogeneous volume while maintaining a high degree of patient comfort and openness. The gradient and RF coils may be positioned above and below the patient instead of 360 degrees surrounding the patient. A smaller RF and gradient coil is made feasible because of the reduced imaging volume.07-08-2010
20110118587OPTIMIZATION OF RF TRANSMIT AND GRADIENT MAGNETIC FIELD IMAGING USING RADIO FREQUENCY AND GRADIENT COILS - The invention provides various systems, machine readable programs and methods for performing imaging using a MR scanner. The MR scanner includes at least one local radio-frequency transmit coil and at least one local gradient coil. The local radio-frequency transmit coil(s) and local gradient coil(s) cooperate to define an imaging volume. The MR scanner further includes a control system for performing an imaging operation on a patient's anatomy disposed within the imaging volume. The control system permits a selective simultaneous increase of the gradient magnetic field strength and peak B1 field strength by substantially the same factor, f.05-19-2011
