| 20080197835 | METHOD AND DEVICE FOR DISTANCE MEASUREMENT BY MEANS OF CAPACITIVE OR INDUCTIVE SENSORS - “The application relates to a method and device for measuring the propagation time of capacitive or inductive fields.” | 08-21-2008 |
| 20080204700 | Method For Light Propagation Time Measurement - In a method and a device for light propagation time measurement, in particular for cameras, a light signal clocked by a clock controller ( | 08-28-2008 |
| 20090212849 | CAPACITIVE MOISTURE INDEPENDENT CRUSH PROTECTION - A protective arrangement for preventing parts of the body from being trapped between at least two mutually relatively moveable parts including at least one strip which is associated with at least one part. There are provided in the strip at least two mutually spaced conductive elements extending in the longitudinal direction of the strip. An electronic sensor system serves to produce an output signal for a capacitance that is adapted to vary as a result of external influences. Due to the fact that at least one first conductive element sends out a signal which is received by at least one second conductive element due to the capacitive effect of the first conductive element and that the second conductive element is at substantially the same electrical potential as the first conductive element and likewise sends out the received signal, there is provided a capacitive crush protection arrangement which does not react to splashes of water or the formation of dew or frost. | 08-27-2009 |
| 20100058645 | METHOD AND APPARATUS FOR TRAPPING INSECTS - An apparatus for catching an insect sitting on a contact surface. The apparatus includes a casing, a light source disposed in the casing for dazzling and immobilizing the insect on the contact surface, and a catch tube disposed in the casing and movable relative to the casing. The apparatus further includes a catch container disposed adjacent to the catch tube and a slider to lift the insect off the contact surface. The slider is movable relative to the casing. | 03-11-2010 |
| 20100181989 | METHOD FOR INDUCTIVE GENERATING OF AN ELECTRICAL MEASUREMENT SIGNAL AND RELATED SENSOR DEVICE - In a method and a sensor device for inductively producing an electrical measuring signal in dependence on a magnitude that is to be measured, there are provided at least two driver coils through which a current is caused to flow in turn at the clock pulse rate of a clock pulse circuit, this current induces a voltage which is dependent on the magnitude that is to be measured in a plurality of coils, the voltage being sub-divided at the clock pulse rate of the clock pulse circuit into voltage signals which are associated with the driver coils, where the voltage signals obtained thereby are evaluated for the purposes of obtaining the measuring signal, where at least two sensor coils are associated with the at least two driver coils, wherein either the sensor coils or the driver coils are connected up in the same sense, whereas the respective other coils are connected up in a mutually opposite sense, and the voltage signals of the sensor coil associated with the driver coils are sampled in certain time periods of the clock pulse signal for the purposes of obtaining the measuring signal. | 07-22-2010 |
| 20100182588 | METHOD AND DEVICE FOR DETERMINING THE DISTANCE TO A RETROREFLECTIVE OBJECT - The invention relates to a method and a device for determining a modification at one object or a modification caused by an object ( | 07-22-2010 |
| 20110095771 | METHOD AND DEVICE FOR ACCURATE CAPACITIVE MEASURED VALUE ACQUISITION - A device and a method for the capacitive detection of an object which is preferably arranged behind a flat article that is transparent to electromagnetic radiation or a wall, including a sensor incorporating sensor electrodes for the detection of the object, preferably for the detection of relative movements between the sensor and the flat article or a finger, where a control circuit serves for the control of the sensor electrodes and for the evaluation of the output signals of the sensor, and, due to the fact that the sensor comprises at least one sensor electrode which is surrounded by at least one further electrode, the surrounding further electrode is connected to the sensor electrode by the control circuit in such a manner that, in the event of a change of the potential of the sensor electrode, the potential of the surrounding further electrode is regulated in the opposite sense to the sensor electrode in such a way that the sensor electrode remains at a pre-determined or pre-definable potential, such that there is produced a capacitive sensor which does not react to tilting or small changes in the spacing from the surface. | 04-28-2011 |
| 20110133756 | APPARATUS FOR CAPACITIVELY MEASURING CHANGES - An apparatus for capacitively measuring changes has a sensor (S) with a sensor-active region. The sensor has at least one transmitting electrode, which generates an electric field, and a further electrode ( | 06-09-2011 |
| 20110163844 | IDENTIFICATION ELEMENT HAVING AN OPTICAL TRANSPONDER - An identification element has a transponder with a data-emitting transmission unit and with a data-receiving reception unit in order to communicate with a device for registering and/or controlling access authorization to spaces or objects. In addition, a control circuit is provided for the transmission unit and reception unit. The transponder is an optical transponder ( | 07-07-2011 |
