Abstract: A method for controlling a device, the method including the steps of, in a processing system: receiving a signal associated with a thought pattern (100), the signal being received from a single electroencephalogram (EEG) channel, the EEG channel having sensed any one or a combination of a visual cortex, a parietal cortex, or the area in between the visual cortex and the parietal cortex, and generating a control signal based on the determined thought pattern (120), the control signal being configured to initiate control of the device.

Abstract: This invention describes a method for determining an abnormality of metabolic function and/or a variation of metabolic function, the method including the steps of, in a processing system receiving electroencephalography (EEG) signal information (100), analysing the signal information (110), and determining the abnormality from the analysis (120). It also describes a method for managing the variation accordingly, the method including the steps of, detecting the abnormality (400), applying patient information (410), determining appropriate dose (420), and providing the required dose (430).

Abstract: A method for forming a disk of a disk drive having a magnetic head for reading data from or writing data to the disk is introduced. The disk is formed of a disk substrate. Additionally, a laser process using a pulse laser with a pulse width of 20˜90 ns and an energy of 0.5˜6.0 ?j is performed to form a plurality of rimless depressions in an inner diameter zone having a radius between 0.65? and 0.78? of the disk substrate, so that a landing zone is formed for landing the slider.

Abstract: The present invention provides a texture measuring method of a hard disk plate. The method comprises performing a laser etching process to form a pinhole at each of a plurality of predetermined positions in a predetermined area on the hard disk plate, measuring the pinhole at each of the predetermined positions to obtain a first measurement value, performing a mechanical texturing process on the predetermined area of the hard disk plate to form circular textures on the predetermined area, and measuring the pinhole at each of the predetermined positions to obtain a second measurement value wherein the first and second measurement values are used to determine the extent of texturing performed on the predetermined area of the hard disk plate.

Abstract: Nowadays, in fabricating a magnetic recording medium, a disk substrate is first mechanically polished to form an even surface. Next, a laser texturing process is performed to produce a textured annular landing zone on the disk substrate. A magnetic layer is then formed on the disk substrate to complete the fabrication process. However, abnormal asperity usually remains on the surface of the disk substrate. Further, as the amount of exposure time in the air increases, an oxide film is inevitably formed on the surface of the disk substrate. Both of them degrade the surface smooth of the disk substrate, resulting in poor control of the size and structure of the laser texture. In addition, due to the irregular distribution of the mechanical polished texture on the disk substrate, a subsequently formed magnetic layer can not easily achieve the desired properties. This invention therefore provides a light texture process for fabricating a magnetic recording medium.
