Abstract: In an apparatus and a method for detecting and assessing a spatially discrete dot pattern disposed in a multidimensional coordinate system, each dot in the pattern assumes at least two differentiatable status values. A measuring device records the coordinate values and status values of each dot of the multidimensional spatial dot pattern. A memory stores data that correspond to the recorded coordinate values and status values of each dot of the multidimensional spatial dot pattern. A computer into which the stored data are entered and in which a coordinate counter for each coordinate value of a coordinate axis is determined from the stored data, is associated with the memory. The value of the coordinate counter is formed from the number of detected dots of the coordinates that have a predetermined status value. A neural network is associated with the computer. An n-dimensional input vector with components formed from the calculated coordinate counters of each dot of the spatially discrete dot pattern is entered in the neural network.      The neural network calculates an output vector by comparing the calculated input vector of the measured dot pattern with stored set-point vectors obtained on the basis of exemplary dot patterns. The neural network assigns a classification value of the measured dot pattern from the output vector ascertained and outputs it.

Abstract: A constant contact spring bearing for use with a railway car truck bolster is disclosed. Greater design flexibility and installation tolerances are available because a longer travel spring, with potentially lower spring load rate and stress rate, may be used. The present invention facilitates the establishment of loadings that may be expected to fall reliably within set-up tolerances from unit to unit. Instead of mounting the spring bearing on the surface of the truck bolster top member, the present invention provides a recess in the truck bolster to receive the spring, allowing for use of longer springs. With longer travel springs available for use, a spring may be selected with a lower load rate and a lower stress rate.

Title: Optical signal power detection with signature bit pattern in wdm systems
Inventor: HARLEY JAMES
IPC: H04B10/077
Filed: 1997-10-22
Granted: 2004-12-07
Abstract: The power of an optical signal (s1) travelling on a channel (.lambda.1) of a WDM transmission system, is measured using a signature bit pattern (s BP1) which is inserted in the frame of the optical signal (s1). The power level of s BP1 is adjusted at the launching point to a predetermined ratio (m) with the power of the optical signal. At a point of interest, the fiber is tapped and a fraction of the tapped signal, that includes a corresponding fraction of s BP1, is converted to an electrical signal. The fraction of s BP1 is extracted from a the electrical signal and power of s BP1 is measured. This gives the optical power of s1 as (m) is known and also the calibration constant for the respective channel (.lambda.1) is known. The method can be applied for any and all channels of the WDM transmission system.
