20130044863 | Radiotherapy and Imaging Apparatus - A radiotherapy apparatus is described which includes a source of radiation for generating a therapeutic beam towards a target region of a patient. A collimation apparatus is configured to act on the beam in a plane transverse to the beam axis. An imaging apparatus is configured to obtain imaging data of the target region. A control apparatus is configured to receive the imaging data from the imaging apparatus and control the collimation apparatus in dependence thereon. The imaging data includes at least one two-dimensional slice image including only a single two-dimensional slice image oriented in any one direction and which includes the target region. | 02-21-2013 |

20090003164 | Fast Disc Recognition by Elimination of Calibrations - A method and a device for fast disc recognition for use in read/write performances when an optical disc is connected to an optical drive, including the provision of a set S of parameters for safe data transfer between the drive and the disc, the direct calibration during a disc recognition step only of those parameters out of said set S in need of a direct calibration, the start of a read/write data transfer sequence after said disc recognition step is finalized and the calibration of the remaining parameters at first after or during one or more data transfer read/write sequences. | 01-01-2009 |
20090022033 | FOCUS CONTROL FOR A MEDIUM SCANNING SYSTEM - An optical disc device and a method are for scanning a medium via a beam of radiation while focusing the beam, in particular for scribing a visible label on a record carrier that has a label side provided with a radiation sensitive layer for creating the visible label. The device has a head for providing the beam and a detector for generating a detector signal (CA) from radiation reflected from the medium. A focus system is provided for generating a focus control signal for focusing the beam of radiation to a spot on the medium. A focus excitation signal ( | 01-22-2009 |

20100091262 | POSITIONING SYSTEM, METHOD, AND LITHOGRAPHIC APPARATUS - A lithographic apparatus includes a positioner configured to position a first part of the apparatus relative to a second part of the apparatus, the positioner including a motor having a motor position dependent motor constant defining a relation between a motor input and a motor output, and a control system to drive the motor, the control system including a set-point generator to provide a reference signal based on a desired position of the first part relative to the second part, and a controller to provide a drive signal to the motor based on the reference signal, wherein the controller includes a compensator which is configured to at least partially compensate the drive signal for the motor position dependent motor constant. The invention further relates to a positioner, a method to optimize the positioning system, and a method to derive a motor position dependent motor constant. | 04-15-2010 |
