Abstract: In a multi-wavelength light detecting and/or emitting apparatus, there are provided at least one of at least of a first unit of a first directional coupler having a grating for an optical coupling function and a photodetector having a photoelectric conversion function and at least a second unit of a second directional coupler having a grating for an optical coupling function and a semiconductor laser, and a common light waveguide extending parallel with the unit in a light propagating direction. The first directional coupler and the photodetector are serially arranged in the light propagating direction and parallel with the common light waveguide, and the second directional coupler and the semiconductor laser are serially arranged in the light propagating direction and parallel with the common light waveguide. When there are formed a plurality of the first units and the gratings have different pitches, wavelength multiplexed light signals can be simultaneously detected per each wavelength with an equal detection performance. When there are formed a plurality of the second units and the gratings have different pitches, laser lights of different wavelengths can be emitted from a single emission end of the common waveguide and the semiconductor lasers can be independently driven.

Abstract: A light transmitter for preventing the degradation of the extinction ratio and the occurrence of pulse width distortion in the light output in spite of the variation of current to light conversion efficiency A of the laser diode. The transmitter uses the characteristics such that the light pulse width becomes narrower than the modulation current pulse width if the laser diode is modulated by a bias current smaller than the threshold level. The light transmitter includes mismatch detection circuit (14) which detects the decrease of the light pulse width. By the detected mismatch signal, the modulation current control circuit (15) limits to increase the modulation current. The modulation current control circuit (15) operates together with the control circuit which controls automatically the light output peak value to be constant.

Abstract: A system that classifies or identifies hand printed or machine printed alphanumeric characters using an iterated least squares polynomial discriminant method is disclosed. Super-sampling of labeled training characters is performed prior to feature extraction. Feature extraction subsamples individual character images. The feature vectors and associated labelings are used to create a weight matrix. During iteration, the weight matrix, to be subsequently used for identification, is modified by determining which characters are incorrectly classified, or classified with too small a confidence, and replicating those characters during training to strengthen the correct classification. The correct classification is also strengthened by using negative feedback to inhibit incorrect classification by using negative values in the target vectors. The speed of the learning process is enhanced by maintaining intermediate matrices and step wise increasing the amount of each feature vector and the size of the sample set used during training. The memory efficiency utilization is enhanced by maintaining and modifying intermediate matrices and compressing the sparse binary features vectors.

Abstract: The circuit amplifies an input RF band of signals and exhibits a signal gain in decibels that is a linear function of a logarithmic control signal input. The circuit employs a transistor having an emitter electrode connected through an inductor/resistor combination to a source of common potential. Within a limited band of RF frequencies, the resistor inductor combination appears to be a high impedance. A PIN diode is connected in shunt across the resistor/inductor combination and, in response to a control current, alters its RF resistance. A capacitor is connector across the emitter of the transistor and provides a tuning function so that, at the mid-frequency of the RF band, a resonant tuned circuit results, thereby causing a high value resistive load to appear across the PIN diode. In this manner, linear gain control is achieved by varying a DC control current through the PIN diode.
