| 20100007867 | Lithographic Apparatus and Calibration Method - In an embodiment, a stage system calibration method includes moving the stage relative to an encoder grid in response to a setpoint signal and measuring a position of the stage by a sensor head cooperating with the encoder grid. The position of the stage is controlled by a stage controller. A signal representative of a difference between the setpoint signal and the position of the stage as measured by the sensor head is registered. The stage system is calibrated from the registered signal representative of the difference. | 01-14-2010 |

| 20090209842 | MRI GRADIENT COIL ASSEMBLY WITH REDUCED ACOUSTIC NOISE - The invention relates to a magnetic resonance imaging system which comprises means for generating a static magnetic field and a gradient coils system for generating a time varying magnetic gradient field by use of a first electrical current and a second electrical current. The gradient coils system is located in the magnetic field and the gradient coils system has a plurality of vibrational modes. Lorentz forces are generated due to the interaction of the first and/or second electrical currents with the superposition of the static magnetic field and the magnetic gradient field. The gradient coils system and/or the first electrical current are adapted so that the integral of the in-products of said Lorentz forces and a vibrational mode of said plurality of vibrational modes is at a value close to zero, wherein said in-products are determined for all points of the gradient coils system, and wherein the integral is determined by summing the in-products determined for all the points. As the above mentioned integral is close to zero or preferably zero, the Lorentz forces are not able to excite the vibrational mode (for example the lowest order bending mode) of the gradient coils system. Thus acoustical noise that is generated by a vibrating gradient coils system is reduced and the comfort for a patient that is examined by the magnetic resonance imaging system is therefore enhanced. | 08-20-2009 |

| 20110246357 | CHARGEBACK RESPONSE TOOL - A method and a system of a chargeback response tool. A chargeback response tool receives chargeback data from a financial vendor and automatically retrieves chargeback dispute evidence relating to the parties involved in the chargeback and about the original transaction from a transaction system that facilitated the original transaction. The chargeback response tool organizes and presents chargeback dispute evidence. The chargeback response tool may also analyze the performance and effectiveness of agents using the tool and of various approaches of disputing chargebacks. | 10-06-2011 |
