Abstract:
A pressure transmitter (50) with an output (88) predicting the magnitude of error in the pressure transmitter's output (57). A pressure sensor (72) is adapted to sense a process pressure (74). A controller (76) coupled to the pressure sensor (72) generates a transmitter output (78) representing the process pressure (74). A memory (80) stores predetermined data predicting magnitudes (82) of transmitter output error as a function of cumulative excessive sensor output levels, and also stores a record of cumulative excessive sensor output levels (86). The controller (76) calculates a predicted present magnitude of transmitter output error as a function of the accumulated record and the predetermined data, and generates the prediction output (88).
Abstract:
The invention relates to a position measuring device (100), which supplies a multidigit code word (P) to a numeric control (300) via a serial interface (14). To determine the current functional state of the position measuring device (100) instantaneous values of analogue sampled signals (S6, S7) are also serially transmitted as multidigit amplitude-proportional code words (D6, D7). Said code words (D6, D7) are supplied to a diagnostic device (200), which displays a Lissajous figure (201) derived from said words, or independently performs an evaluation and generates warnings or alarms.

Abstract:
A sensor unit (11) has a sensor (12) and a processing device (13, 14) for processing an output signal (A, A') taking into account a parameter (T). The parameter (T) can be input into the processing device (13, 14) by subjecting the sensor (12) to a sequence of predetermined environmental conditions. This can take place by means of a programming device (19) with an inputting device (21) and an actuator (20). Said actuator (20) can be activated according to a parameter input by the inputting device in such a way that the actuator produces a sequence of environmental conditions corresponding to said parameter.
Abstract:
The invention relates to a position detection system having a sensor arrangement (14) for generating at least one sensor signal according to a body (11) that moves past. The sensor signal/s continually change/s when said body moves past. The at least one sensor signal is compared to at least one reference value in a comparator arrangement (20). Control means are provided for electronically adjusting the sensor arrangement (14) by changing the reference value. The output signal of the comparator arrangement (20) forms the position signal (P) for detecting a relative position of the body (11) and the sensor arrangement (14). The sensor arrangement can thus be mechanically positioned in a relatively imprecise manner and fine tuning can be carried out electronically by changing the reference value.
Abstract:
An inspection chip used for sensor measurement has a structural feature such as a projection, a recess, or a through hole on/in a portion that a user may grasp. The state such as the size, the number, or the portion of the structural feature(s) of the inspection chip is different from that of a correction chip similar to the inspection chip in shape. Even a visually-handicapped person or a person having weak eyes can distinguish the inspection chip from the correction chip by sense of touch thanks to the difference in the structural feature, thus preventing the user from mistaking one of the inspection and correction chips for the other.
Abstract:
The invention relates to a method for establishing a table of correction values for recognising the deviations from zero in a sensor module of a vehicle. According to said method, at least one, preferably at least two sensors which detect the movement of the vehicle and at least one temperature sensor are provided. The invention also relates to a method for determining a corrected sensor signal and to a sensor module for determining a corrected sensor signal. A table of correction values is established using the following steps: Determination of the deviations from zero of the sensor, by running the latter through a temperature profile in a calibration mode and Classification of the deviations from zero of the sensor and allocation of temperature values or classes to said deviations.

The present invention provides a method and system for monitoring a composite optical signal in an optical network. The method includes separating the composite optical signal into a plurality of subsets, each subset including a plurality of data points, and detecting the plurality of data points. The method and system in accordance with the present invention utilizes an optical performance monitor which is able to obtain the entire spectrum in a matter of milliseconds. The preferred embodiment of the optical performance monitor utilizes a plurality of separator modules (406) to separate sets of data points of the optical signal and transfer these data points to a device for analysis. The method and system of the present invention is faster than a conventional performance monitor. Because the optical performance monitor of the present invention allows the spectrum to be obtained in fractions of a second, real-time performance monitoring is provided.
Abstract:
According to the inventive method for configuring the sensor, the sensor (1.1 1s) continuously compares sensor data (SD) detected in the sensor mode to ensure that they correspond with characteristic, stored, predetermined sensor data (SDM). As soon as the sensor has established that the data correspond, it switches from the sensor mode to a configuration mode. The data corresponding to the characteristic sensor data (SDM) are used for configuring the sensor (1.1 1.s). After this configuration data has been received, the sensor switches back to sensor mode. The invention also relates to a configurable sensor. Said sensor is provided with a comparator (3), which continuously compares sensor data (SD) detected by a sensing element (2) to ensure that they correspond with the characteristic, stored, predetermined sensor data (SDM). An electronic evaluating device (4) for configuring the sensor is also provided. The comparator (3) intermittently subjects said evaluating device to the received sensor data as soon as it is established that the data correspond.
