Title: Code transmitting apparatus and code transmission system
Inventor: KIMURA TOMOHIRO
IPC: H03M7/40
Filed: 1992-06-26
Granted: 1998-06-23
Abstract: Although data is transmitted with efficiency by an arithmetic encoding system, the number of carry control signals increases in proportion to the number of consecutive bits "1" s or bytes X'FF's in a conventional system.  In the present invention, an arithmetic encoder 302 detects the possibility of a carry generated during arithmetic coding operation being propagated beyond at least a predetermined number of consecutive bytes X'FF's in a supplied arithmetic code 315.  When the propagation of the carry is impossible, a carry control signal is inserted into the first 2 bits of the byte other than X'FF' which occurs immediately after the consecutive bytes X'FF's so as to transmit the presence or absence of a carry.  An arithmetic encoder 303 detects the continuation of at least a predetermined number of bytes X'FF's in the arithmetic code 315, and arithmetically decodes an output value YN316 on the basis of the predicted value MPS317 of the occurrence probability of the output value YN316 to be encoded and the region width Qe of the complementary predicted value LPS.  Since the number of total bits of the inserted carry control signals is reduced by this "one-time 2-bits insertion system", the total number of transmitted code bits is also reduced.

Granted: 1999-12-14
Abstract: An image processing apparatus judges the degree of similarity between entered image data and characterizing data of a special image (an image containing a special original such as a bank note or negotiable instrument) prepared in advance, generates data indicative of the degree of similarity and integrates similarity data in two-dimensional space while subjecting the entered image data to image processing conforming to the results of integration. For example, image data of an area for which the degree of similarity resulting from integration indicates a certain value is forcibly converted into data having maximum density.

Abstract: We have discovered that silica-based optical fibers (e.g., 33) that are doped with Ge, Al and a rare earth (e.g., Er) can be very susceptible to hydrogen-induced attenuation change. For instance, such fiber can exhibit loss increase rates that are, at 20°C, 106 times larger than those of a standard single mode fiber. We also believe that transition metal-doped silica-based fibers can exhibit large hydrogen-induced attenuation change. In many circumstances- (e.g., amplifier fiber, attenuator fiber) significant attenuation change of optical fiber is undesirable. We disclose that such change can be substantially eliminated by provision of hydrogen gettering material and/or a "hermetic" fiber coating. It is currently preferred to provide silica cladding material that is a hydrogen getter, and also provide a "hermetic" fiber coating. Containment of the fiber, together with a quantity of a gettering material (e.g., ErFe2) in an essentially hermetic enclosure is also disclosed.

Abstract: An expander circuit for decoding audio signals which were encoded in accordance with the BTSC multichannel sound system standard including DBX companding is presented. A wideband expander circuit is utilized and a DBX expander can be accommodated. The wideband expander circuit is provided with a signal path having an input LPF (low pass filter), a stereo difference signal (L-R) demodulator, a second LPF, and a voltage controlled amplifier (VCA), the gain of which is controlled by a control signal derived from the demodulated difference signal which has been operated on by a bandpass filter (BPF) and an integrating peak detector. The output of the VCA is provided to a deemphasis network before being fed to a decoder matrix for combining with the sum stereo signal (L+R) for reconstructing the original L and R signals. When a DBX expander is connected, the DBX expander is substituted in place of the deemphasis network, the VCA control signal, which provides the wideband expansion, is overridden by a predetermined voltage, the BPF are is disabled, and the input is switched to bypass the input LPF. According to aspects of the present invention, the disablement of the BPF actuates the switching of the input to bypass the input LPF.

Abstract: If the process were to be changed for optimizing the injection of hot electrons into the channel of the memory transistor in the manufacture of an integrated circuit comprising an embedded EPROM, this could lead to degradation of the transistors in the logic, in particular in the case of channel lengths below 1 µm. To prevent this, a process is presented by which the non-volatile memory is optimized without the properties of the logic being affected by this. For this purpose, according to the invention, a first series of steps is performed in which first the floating gate is defined, followed by the source/drain implantation and a side-wall oxidation for obtaining an oxide spacer on the sides of the floating gate. During these steps, the region of the logic to be formed is uniformly protected against implantation and oxidation by the same poly layer from which the floating gate is made. Then, in a second series of steps, the usual CMOS process is carried out whereby first the gates of the transistors are formed, followed by the necessary source/drain implantations.

Abstract: A number of octapeptides were generated from the sequences encoding the 60 kDa Ro/SSA peptide, the La/SSB autoantigen, the 70 kD nuclear ribonucleoprotein (nRNP), and the Sm B/B' polypeptide, which represent linear epitopes for autoantibodies present in the sera of SLE and SS patients. These peptides are useful in solid phase assays for patients characterized by the presence of these autoantibodies, and can be used to categorize patients as to the likelihood of developing certain conditions associated with SLE. The peptides are also potentially useful in treatment of these patients using immobilized peptide to remove autoantibody and to block binding of the autoantibodies with patient molecules reactive with the autoantibodies.

Abstract: A processing method that processes interferometer data to provide for rejection of multipath signal returns from an emitter and computes an improved estimate of the relative angle between the emitter and an interferometer. The present processing method comprises the following steps. Interferometric data is gathered that comprises complex signal amplitudes derived from the emitter at a plurality of emitter angles relative to the interferometer. The complex signal amplitudes derived at each of the plurality of emitter angles are processed by maximizing a predetermined log likelihood function corresponding to a natural logarithm of a predetermined probability density function at each of the plurality of emitter angles to produce a plurality of maximized log likelihood functions. The improved estimate of relative angle between the emitter and the interferometer is made by selecting the emitter angle corresponding to an optimally maximized log likelihood function. The present method rejects multipath signal returns from an emitter and computes an improved estimate of the angle between the emitter and the interferometer. The present processing method may be employed to reject radome reflections in radars, particularly those employing antennas having a relatively low radar cross-section.

Abstract: An auxiliary video data slicer for extracting auxiliary video information in a video signal includes a peak detector (220, 230) for determining the peak amplitude of horizontal sync pulses and of a run-in-clock (RIC) waveform included in the auxiliary video information. A variable threshold voltage (PEAK VREF) for the peak detector is varied in a first range to detect the sync pulse peak. A threshold voltage (SYNC VREF) for detecting the leading edge of sync pulses is derived from the peak amplitude of the sync pulses. The location of the RIC waveform interval within a particular line of video is determined based on the detection of a sync pulse edge (SYNC). The variable threshold voltage is varied in a second range to detect the peak amplitude of the RIC signal. A data slicing threshold level (DATA VREF) for extracting auxiliary video information is derived from the peak value of the RIC signal. The auxiliary video data slicer may be implemented in an integrated circuit.
