| 20090021275 | METHOD AND ARRANGEMENT FOR POSITIONING A PROBE CARD - A method for perpendicular positioning of a probe card relative to a test substrate, includes storing a separation position approached in a first positioning step as a distance between the needle tips of the probe card and the substrate, storing a contact position approached in a second positioning step until the probe card contacts the substrate, and displaying an image of the needle tips. For avoiding erroneous operation after a probe card has been changed, when imaging the needle tips, the stored contact position is imaged and is changed until presentation of this contact position corresponds to actual height of the tips appropriate for the respective probe card and this setting is then stored as a new contact position. A display device presents the needle tips and the stored contact position and is connected to a memory, a recording device and an input device which changes the contact position. | 01-22-2009 |

| 20110122414 | OFFICIAL SYSTEM FOR ILLUMINATING A MEASURED OBJECT AND INTERFEROMETRIC SYSTEM FOR MEASURING SURFACES OF A MEASURED OBJECT - An interferometric system for measuring surfaces of a measured object using an optical system. The optical system has a beam splitter, which directs measuring beams in a first beam path and measuring beams in a second beam path onto the surfaces of the measured object with the aid of two mirrors. The beam paths which are formed by the light beams which are reflected on the surfaces at least partially overlap in an area having identical beam direction. In this manner, measured surfaces of the measured object are at least partially imaged on an identically irradiated surface of a detector, such as an image recorder. | 05-26-2011 |

| 20080265190 | Electromagnetic Pressure Regulating Valve Device Having an Integrated Pressure Sensor - An electromagnetic pressure regulating valve device for regulating a hydraulic pressure including at least one pressure regulating valve which includes a solenoid part having at least one bobbin holding an electric coil, a coil core and a movably guided armature; a valve part having at least one supply connection, one return connection, one load connection and one actuating element operated by the armature and cooperating with a valve seat; and an electronic part having at least one pressure sensor for measuring the hydraulic pressure present at the load connection. At least the pressure sensor is situated on an end of the solenoid part facing the valve part upstream from the electronic part. Positioning the pressure sensor close to the valve part may substantially reduce the filter effect of the transmission link, and the hydraulic pressure to be measured is therefore transmittable free of errors up to a much higher cutoff frequency. This may result in a higher measurement accuracy, and therefore also a higher regulation accuracy, of the pressure regulating valve. | 10-30-2008 |
