Title: Using a supervision signal to control an amplifier to obtain even gain with respect to wavelength
Inventor: CHOI DOE-IN
IPC: H04B10/00
Filed: 1998-07-15
Abstract: Wavelength division multiplexed optical amplifier controlling system and method are provided. The wavelength division multiplexed optical amplifier controlling system includes an optical exchange system for generating and interpreting a supervision channel optical signal, multiplexing the supervision channel and data channels comprised of a plurality of optical signals having different wavelengths, and transmitting and receiving the multiplexed channels and a plurality of optical amplifying portions located on a transmission path connected to the optical exchange system, for performing amplification so as to have even gain with respect to predetermined wavelength range which the data channel optical signals have according to the supervision channel optical signal information, and inserting the state information thereof into the supervision channel when the optical exchange system requests the state information thereof. According to the present invention, since an optical filter in each wavelength for supervision in a WDM-EDFA because a supervision channel having a predetermined wavelength is used is not necessary, the structure of the WDM-EDFA becomes simpler. Therefore, it is possible to lower costs and there is no loss of optical signals which occurs by using a conventional optical demultiplexer.

Title: Controlling a motion effector for use in a virtual reality system
Inventor: KIM JEOUNG TAE
IPC: G05B13/04
Filed: 1998-08-12
Abstract: Plant 360 is the target of control and produces an output signal y(t) reflecting by means of a sensor, the actual movement of a moving part therein. Reference input provider 310 provides a reference input signal r(t) which reflects a desired motion of the plant. Subtractor 320 produces an error signal e(t) by subtracting the output signal from the reference input signal. A feedback compensator 330 generates a first control signal u b (t) by using the error signal and a feed-forward compensator 340 generates a second control signal u f (t) by using the reference input signal. Adder 350 generates a final control signal u(t) by adding the first and the second control signals and provides the final control signal to the plant. This arrangement improves the response of the system and reduces the effect of external disturbances, modelling errors and sensor noise.

Title: Method for control and regulation of doors driven by an electromechanical motor
Inventor: STARK JUERGEN
IPC: E05F15/60
Filed: 1994-11-02
Abstract: An electromechanically operated door having a control and regulation system for the door, the door for being driven by an electric motor, the movement of the door being controlled by sensors. The control and regulation system is equipped with a microprocessor control. In addition to the normal path of data to the microprocessor control, a dual redundancy is achieved, in that there is a safety monitoring system which receives the same safety-related information as the microprocessor control. This safety monitoring system, for its part, is capable of detecting a fault, i.e. if the microprocessor control system has not shut off the door, the door is shut off by the safety monitoring system, which for its part reports any faults which occur in the system to a fault detection unit, and here again, by means of a redundant shutdown unit, brings the connected motor and thus the door to an immediate stop. In addition to the automatic verification of the safety-related functions, manual verification of the safety functions is also possible. Also contemplated is a control and regulation system, having the above features, for a door.

Title: Tungsten recovery from scrap alloys
IPC: C22B7/00
Filed: 1986-03-28
Abstract: The scarcity of high grade tungsten ores obliges users to seek to recover it from scrap materials, but drill bits in particular pose especial problems. Existing proposals to use acidic hydrogen peroxide to oxides and solubilize tungsten is extremely inefficient in reagent consumption per unit tungsten recovered. According to the present invention, hydrogen peroxide can be used considerably more efficiently in the extraction of tungsten into an aqueous acidic solution by employing certain promoters which are solid at 50 DEG  C. in the form of fused blocks. These blocks release the promoter slowly into the reaction solution and achieve similar efficiency of use of hydrogen peroxide and acid but at markedly reduced consumption of promoter in comparison with the same promoter added in powder or granular form. Examples of such promoter are hydroxy or amino substituted aromatic carboxylic acids e.g. 2-hydroxybenzoic acid. The promoters can most conveniently be used in a multi-stage tungsten extraction process.
