20100036517 | SEMICONDUCTOR MANUFACTURING APPARATUS - A semiconductor manufacturing apparatus includes a first program on a controller and a second program on an interface board between the controller and controlled devices. Both of the programs update their own counters and exchange their counter values with each other, serving as bi-directional software watchdog timers (WDT). If a counter value of the first program on the controller sent to the second program on the interface board is determined to be abnormal by the second program, the second program on the interface board sends commands to the controlled devices to terminate output so that the apparatus is navigated to a safe mode. The first program similarly monitors the counter values of the second program for anomalies. This bi-directional software WDT can be implemented as add-on to software programs that already exist in the controller and the interface board, therefore, this implementation does not incur extra cost of hardware of the apparatus. | 02-11-2010 |

20090012385 | Magnetic Resonance Imaging Device and Method - A magnetic resonance imaging apparatus including signal receiving means for detecting a nuclear magnetic resonance signal from an object, signal processing means for reconstructing an image by using the detected nuclear magnetic resonance signal and display means for displaying the image, a whole image of the examiner being obtained while each imaging site of the object is continuously or stepwise moved and disposed in the imaging space, is equipped with detecting means for detecting the gradient and size of each site of the object, inputting means for inputting reference information for carrying out magnetic resonance imaging corresponding to the gradient and size of each site of the object onto an image representing the gradient and size of each site of the object which is displayed on the display means, storage means for storing the input reference information, control means for controlling the imaging operation on the basis of the reference information stored in the storage means, and combining means for combining nuclear magnetic resonance signals obtained through the imaging operation carried out under the control to create the whole image. | 01-08-2009 |
20090091323 | MAGNETIC RESONANCE IMAGING APPARATUS AND METHOD - A magnetic resonance imaging apparatus comprises static magnetic field generating means for generating a static magnetic field in an imaging space, a gradient magnetic field generating means for generating a gradient magnetic field in the imaging space, high-frequency magnetic field generating means for generating a high-frequency magnetic field so as to induce nuclear magnetic resonance in a subject placed in the imaging space, signal receiving means for detecting a nuclear magnetic resonance signal from the subject, signal processing means for reconstructing an image by using the detected nuclear magnetic resonance signal, display means for displaying the image, a table for placing the subject thereon to dispose the subject in the imaging means, and table moving means for moving the table on which the subject is placed. | 04-09-2009 |
20090278535 | Magnetic resonance imaging apparatus and method - In performing the moving table imaging, an MRI apparatus and a method thereof are provided, which minimizes image degradation and reduces imaging time. When an image of a wide range of a test object is taken, the imaging is repeated while changing the gradient magnetic field intensity in a phase-encode direction, as well as changing the size of field of view FOV in the readout direction by changing the readout gradient magnetic field intensity in reading out the data, according to the phase-encode amount. In a part where the FOV is expanded, data acquisition frequency is lowered, and consequently, the total imaging time is reduced. The data sampling time may be changed along with the change of the FOV, and therefore, a process for achieving a unique matrix size in the readout direction is rendered unnecessary, and a spatial resolution can be maintained. | 11-12-2009 |
