| 20090009734 | Lithographic apparatus and device manufacturing method - In an immersion lithography apparatus, ultrasonic waves are used to atomize liquid on a surface of the substrate. | 01-08-2009 |
| 20100000333 | FLUID FLOW METER USING THERMAL TRACERS - Fluid flows through a conduit. To measure flow speed the fluid is heated at a heating location in the conduit with a time-dependent heating strength. A speed of sound in fluid flowing in the conduit is measured at a plurality of sensing locations downstream from said heating location. The flow speed of the fluid is determined from a delay with which the time dependence is detected in the sound speeds measured at said sensing locations. In an embodiment a frequency of the variation of heating strength that is used to determine the flow speed is selected automatically dependent on the flow speed and/or other circumstances. | 01-07-2010 |

| 20110087444 | SYSTEM FOR ULTRASONICALLY DETECTING DEFECTS IN A PIPE WALL - A system for detecting defects in a pipe wall, comprises an ultrasonic transducer which is arranged for emitting, via an exit opening, ultrasonic signals from the interior of the pipe towards its wall and for receiving, via an entrance opening, backscattered signals from the wall. The system is arranged to emit and receive a multitude of signals having their main directions within a plane mainly perpendicular to the pipe axis. The openings are configured to make the ultrasonic transmission signal diverge and/or to receive back signals from a diverging range of angles over a large area of the pipe wall, by using openings with a diameter with magnitude of the wavelength of the ultrasonic signals. Sets of emitted and backscattered signals for different emission and reception positions are processed, in processing means, to form an image based on transmission times between emission and reception of backscattered signals. | 04-14-2011 |

| 20110161065 | ULTRASONIC MODELLING - A method of producing a temperature model of a surface of an object using ultrasonic transducers comprises the steps of iteratively adjusting a temperature model by using measured travel times of ultrasonic waves and their predictions model-based. The ultrasonic waves used for producing the temperature model are preferably substantially non-dispersive ultrasonic waves. The method may further involve a height model of the surface, which height model is produced using substantially dispersive ultrasonic waves and is corrected by using the temperature model. | 06-30-2011 |
