Abstract: A broadband light source is fabricated from an optical transmission medium having an amplification material such as rare earth doped (e.g. erbium) fiber. The natural emission spectrum of this amplification material is corrected. The weak emission wavelength region has been enhanced and the whole spectrum flattened. The source outputs high power with about 25% pump efficiency. The spectrum is stable and the power density is equalized through out the emission region.

Abstract: The purpose is of avoiding the sliding frictions also in that case in which both elements (2, 3) in which the annular tracks (5, 6) for ball (4) rolling are provided get positioned with their symmetry axes (10, 11) being mutually incident. Due to this reason, the traditional pivot and the corresponding female hollow cooperating with it have been eliminated. The side portions (8) of the annular tracks (5, 6) have now a development characterized as follows: .cndot. it is extended enough in order to retain the rolling bodies (4) inside the hinge (1-1G) during their rolling along the annular tracks (5, 6); .cndot. and is limited enough in order to generate between the first element (2) and the second element (3) in the region of the rolling bodies (4), an annular gap (9) which is wide enough in order to prevent any contacts between the first element (2) and the second element (3) also in the case when their respective symmetry axes (10, 11) are mutually incident.

Abstract: A direct conversion receiver for a delay-and-correlate transmitted reference spread spectrum signaling method and apparatus is based on minimal component digital circuitry instead of analog delay and multiplier circuits. The method allows direct RF to baseband conversion and eliminates the need for an IF stage. The receiver includes an RF convener for converting a received direct sequence spread spectrum signal to baseband. An analog-to-digital converter samples the baseband signal at a rate greater than the chipping rate of the direct sequence spread spectrum signal. A delay stage coupled to the output of the analog-to-digital converter generates a delayed signal. Multiplier logic receives output signals from the analog-to- digital converter and the delay stage and, in response, generates control output signals. A counter responsive to the control output signals increments or decrements a count or recycles, depending on the decoded control output signals.

Abstract: An inspection system for a welding apparatus for performing welding by supplying electric power outputted by an inverter based on a command from a welding control unit, through a welding transformer to a welding gun. The inspection system includes a first input/output section for receiving positive and negative components of a waveform outputted by the inverter and for outputting waveforms, a second input/output section for receiving waveforms outputted by the welding control unit and for outputting waveforms similar to those outputted by the inverter. A selector selects the operation of either the first or second input/output sections. A first OR circuit has applied thereto the first waveforms outputted by the first and second input/output sections, and a second OR circuit has applied thereto the second waveforms outputted by the first and second input/output sections. A third OR circuit has the outputs of the first and second OR circuits applied to the inputs thereof. A comparator compares the number of waveforms outputted from the third OR circuit with a predetermined value within a predetermined time. If the number of the waveforms outputted is equal to or larger than the predetermined value, it can be determined that the welding control unit or the inverter is operating normally. If the number of the waveforms outputted is smaller than the predetermined value, it can be determined that the welding control unit or the inverter is operating abnormally.

Title: Method and apparatus for generating a model of an industrial production
Inventor: REINE FRANK
IPC: G05B17/02
Filed: 1998-04-30
Granted: 2000-08-08
Abstract: A process model of an industrial process or system is generated. The model correlates a first number M of process parameters forming  input  values  with  a  second  number  L  of  quality characteristics forming output values, which are processed to form feedback control signals for the process or system.  A third number N of training data sets of the industrial process are first gathered.  These data training sets are then processed in a second step during a learning phase of the model with the help of a processing unit such as a personal computer, whereby a preliminary approximating model  is  used  including a neural network with local approximation characteristics.   The neural network is connected in parallel with a linear network.  Both networks are connected to the same inputs.  The neural network first has a further number K of neural cells.   This initial number K corresponds to the number N of training data sets.  A weighted linear combination of the M process parameters  is performed.   The  linear network and the neural network are connected with their outputs through weighting circuits to a common summing network.  A reduction step is performed, whereby the neural and the linear network become smaller with fewer neural cells and with M-R weighted linear combinations by using the method of stepwise regression to ascertain a final simpler process model as compared to the initial preliminary model for providing closed loop feedback signals to control the industrial process such as a chipboard production process.

Les passages du courant entre les surfaces de préhension sont améliorés afin d'obtenir efficacement une hémostase sans que les tissus ne collent aux surfaces de préhension. La configuration géométrique de la pièce d'espacement permet de nettoyer facilement les pinces. Les bords et les parties avant des extrémité des branches présentent des surfaces conçues pour assurer le passage efficace du courant sur les surfaces latérales, ce qui améliore le rendement des pinces lorsqu'on les utilise pour effectuer la coagulation dans un mouvement de balayage.
