摘要： There is provided a method for referencing and correcting the beating spectrum generated by the interference of the components of a frequency comb source. The proposed method allows monitoring of variations of a mapping between the source and the beating replica. This can then be used to compensate small variations of the source in Fourier transform spectroscopy or in any other interferometry application in order to overcome the accuracy and measurement time limitations of the prior art. Constraints on source stability are consequently reduced.

摘要： The invention relates to a field device (3) for determining or monitoring a process variable in process automation systems. Said field device consists of a sensor (1), working according to a defined measuring principle, and a control/evaluation unit (2) that processes and evaluates the measurement data supplied by the sensor (1). The control/evaluation unit (2) is at least partially configured as a re-configurable logic device FPGA having a plurality of dynamically re-configurable functional modules (4). An interface (25) is provided via which the control/evaluation unit (2) receives sensor- and application-specific data on a defined sensor type in a respective defined process application. The control/evaluation unit (2) configures the functional modules (4) in accordance with the sensor- and application-specific data in such a manner that the field device (3) is optimally adapted to the process variable to be determined or to be monitored and to the current process application of the field device (3).

摘要： A chopped Hall effect sensor topology includes a switched Hall plate, an amplifier responsive to an output of the switched Hall plate and a filter stage responsive to the output of the amplifier and including an anti-aliasing filter and a selective filter that is tuned to the modulation frequency. The switched Hall plate includes a Hall element and a Hall plate modulation circuit that modulates the Hall offset signal component or the magnetic signal component. In embodiments in which the Hall offset signal component is modulated by the switched Hall plate, the amplifier, if chopped, includes an even number of additional modulation circuits. In embodiments in which the magnetic signal component is modulated by the switched Hall plate, the amplifier contains an odd number of modulation circuits. The described topology provides a low noise, fast response time Hall effect sensor.

摘要： A sensor (10) has an output coupled to a first comparator input. A control circuit (18) is arranged to switch from an upward tracking mode to a downward relative level detection mode, to a downward tracking mode, to an upward relative level detection mode and back to the upward tracking mode successively. A first and second digital to analog conversion circuit (14a,b) receive a first and second digital control value from the control circuit (18) respectively. A controllable combiner circuit (16) has inputs coupled to outputs of the first and second digital to analog conversion circuits (14a,b) and an output coupled to the second comparator input, the control circuit (18) having first output coupled to controllable combiner circuit (16) to cause the combiner circuit (16) to supply first and second combiner output signals determined by the first and second digital to analog conversion circuit (14a,b) to the second comparator input in the upward and downward tracking mode respectively, and to supply a third combiner output signal corresponding to an average of the first and second combiner output signals to the second comparator input in the relative level detection modes. The control circuit (18) has an input coupled to the output of the comparator (12), the control circuit (18) controlling one directional upward tracking by the first digital to analog conversion circuit (14a) of upward changes of the sensing signal in the upward tracking mode, and controlling one directional downward tracking by the second digital to analog conversion circuit (14b) Of downward changes of the sensing signal in the upward tracking mode.

摘要： Die Erfindung betrifft ein Verfahren zur Erkennung eines Sensors an einem Messverstärker und ein Verfahren zur Synchronisation eines Sensors mit einem Messverstärker. Der Sensor (1) ist mittels eines Steckers 5 mit einem Messverstärker (4)verbindbar. Der Messverstärker (4) umfasst wenigstens ein Kontaktpaar (11) mit einem ersten Kontakt (12) und einem zweiten Kontakt (13). Der Stecker (5) umfasst wenigstens ein Kontaktpaar (7) mit einem ersten Kontakt (8) und einem mit dem ersten Kontakt (8) gekoppelten zweiten Kontakt (9), wobei die Kontakte des Messverstärkers (4) und des Steckers (5) miteinander kontaktierbar sind. Zum Erkennen, ob der Sensor (1) an dem Messverstärker (4) angeschlossen ist, legt der Messverstärker (4) ein elektrisches Potential an einen Kontakt des Kontaktpaares an und misst das elektrische Potential an dem zweiten Kontakt des Kontaktpaares, wobei der Messverstärker (4) das elektrische Potential des ersten Kontakts mit dem elektrischen Potential des zweiten Kontakts vergleicht. Stellt der Messverstärker (4) hierbei aufgrund des gleichen Potentials an den Kontakten fest, dass ein Sensor (1) angeschlossen ist, kann der Messverstärker (4) die Daten aus einem Speicher (2) des Sensors (1) auslesen und der Messverstärkers (4) wird aufgrund der ausgelesenen Daten justiert.

摘要： A package measurement apparatus comprising three measurement devices, one for each dimension. Each measurement device comprises a plurality of signal receptor modules. Each module comprises a row of signal receptor, and a signal energy source. In a first calibration step, the outputs of each receptor are standardized to reference maximums and minimums. In a second calibration step, calibration sets of receptor outputs are created and recorded. During measurement, a measurement set of receptor outputs is obtained and matched with a calibration set of receptor outputs to determine the dimension of an object.

摘要： In a method for determining an output value from a sensor in automation engineering which has a non-linear characteristic curve K prescribed on a point-by-point basis, auxiliary points Hj are additionally produced in accordance with a simple computation code. The output value is obtained from the input value by interpolating at least two points on the characteristic curve.
