Abstract: In a level control device for producing an output signal in digital modulation with an amplitude variation, a control signal generator (19) comprises an AD converter (23) for converting to a digital value a level of a signal produced by a level detector (17) by detecting the output signal, a processor (25) for providing a processed value by comparing the digital value with a reference value, and a DA converter (27) for converting the processed value to a control value for controlling a variable attenuator (11). Controlled, the attenuator produces an attenuated signal which is used as the output signal with its level or power kept at a controlled value determined by the reference value.

Abstract: An apparatus monitors a web of textile material which is also processed by a textile processing machine. The web is in motion relative to an imaging unit, and the imaging unit repetitively scans at least one strip across the web in a direction substantially perpendicular to the direction of relative motion of the web. A computer receives signals from the imaging unit and produces digital data corresponding thereto. The computer further analyzes the digital data to find entities of interest in the web and determines parameters of the found entities of interest. Preferably, the imaging unit and computer include distinguishing means for producing a plurality of optical images of the same portion of the web where each of the optical images are distinguished one from the others by the spectral content. In addition, the imaging unit and computer produce a plurality of time separated images, where each of the time separated images are produced during different lighting conditions on the web. In one embodiment, one image is produced while the front side of the web is illuminated, and another image is produced on the same portion of the web while the rear side of the web is illuminated.

Abstract: There is now provided a method of machining and shaping a through opening in a fiber-reinforced composite material starting from a preformed hole. At least one rotation symmetrical milling body with a substantially smaller diameter than that of the preformed hole is placed in that hole and the opening is machined and shaped by the milling body partly rotating around its own axis, partly by a translational movement relative to the edge of the opening. According to the method, the fiber-reinforced material is oriented in such a way that the axis of rotation of the milling body is essentially perpendicular to the longitudinal direction of the fibers at the edge of the opening. The size and/or form of the finished opening differs significantly from that of the preformed hole. The radial spread of the damages and/or the defects define a lower limit for the amount of material removed.

Abstract: This invention relates to a method and apparatus for recognizing a script written character. 
     The character is entered using character entering means and digitised by appropriate means. The digitised character is then stored in, for example, a memory. Codes representing topological vector features of the character are extracted from the character, then the topological and vector features of the character are compared with a set of reference topological and vector features stored in a memory. Each of the set of reference characters corresponding with a specific script written character. A logic process is then performed to determine which of the set of reference features most closely corresponds to the topological features of the digitized character thereby identifying the script written character. The relative weighting of the topological effect and the vector effect can be varied for different types of script to enable still more accurate recognition.

Abstract: An output driver circuit for an integrated circuit is disclosed, where the output driver drives an output terminal with a high logic level having a voltage limited from the power supply voltage of the integrated circuit. The limited voltage is provided by applying a limited output high voltage to an output buffer, such that the drive signal applied to the gate of the pull-up transistor in the output driver is limited by the limited output high voltage applied to the output buffer. A voltage reference and regulator circuit for generating the limited output high voltage is also disclosed, and is based on a current mirror. The sum of the current in the current mirror is controlled by a bias current source, which may be dynamically controlled within the operating cycle or programmed by way of fuses. An offset compensating current source adds current into the reference leg of the current mirror to eliminate the development of an offset voltage in the current mirror, and the limited output high voltage is shifted by the threshold voltage of the pull-up drive transistor by way of a threshold shift circuit.

Abstract: The system uses a sound pressure sensor or microphone which is connected with a regulator and a loudspeaker. In the regulating circuit, the input is the sound pressure of the interference inside the motor vehicle (Pst r). The feedback is the sound pressure from the active sound absorption system (Pactives system). The difference between the input and the feedback, is the actual pressure inside the motor vehicle (Pges). This is then fed to three series connected filters. The first filter (HMik) represents the transfer function of the microphone and the second filter (HRegler) represents the transfer function of the regulator. The third filter represents (HLS) the transfer function of the loudspeaker. The second filter gives an output signal (ULS) to the loudspeaker, deflecting the membrane by the amount (xLS), used as feedback with the transfer function (HLS-Mik) to form the sound pressure from the active sound absorption system (Pactive system).

A single MMU translates addresses of the two distinct architectures under control of the mode bit which is also used to simultaneously inform instruction decode which architecture is being used so that instructions are properly decoded. The MMU is also capable of mapping the address translation of one architecture onto that of the other so that software written for both architectures may be multi-tasked under the control of a single operating system.

Abstract: A gain equalizer which equalizes gain versus wavelength characteristics of an optical amplifier. The gain versus wavelength characteristics of the optical amplifier include first, second and third gain peaks in a wavelength band with the second gain peak being between the first and third gain peaks. The optical amplifier amplifies an input signal in accordance with the gain versus wavelength characteristics to produce an output signal. The gain equalizer includes first, second and third optical filters having first, second and third transparency characteristics, respectively. The first, second and third transparency characteristics are periodic waveforms having different periods related to the wavelength difference between the first and third gain peaks. The second transparency characteristic is a periodic waveform having a period equal to 1/(2 n ) of the period of the waveform of the first transparency characteristic. The third transparency characteristic is a periodic waveform having a period equal to 1/4 of the period of the waveform of the first transparency characteristic. For example, the first transparency characteristic is a periodic waveform with 1/4 period extending between the first and third gain peaks, the second transparency characteristic is a periodic waveform with one period extending between the first and third gain peaks, and the third transparency characteristic is a periodic waveform with two periods extending between the first and third gain peaks.
