Abstract: A transceiver for a cellular telephone, particularly a portable telephone, comprises a transmitter (1) and a receiver (2) coupled to a common antenna (3) by an antenna duplex filter (4). The duplex filter (4) comprises two passband filters (5, 6) connected respectively to the transmitter (1) and the receiver (2). The receiver (2) comprises a first amplifier (7). A notch filter (8) tuned to the transmit frequency is connected to the output of the amplifier (7). The notch filter (8) enables the filtering performance of the receive filter (6) to be relaxed, and the location of the notch filter(s) at the output of amplifier (7) means that the insertion loss is less critical. The requirement for lower filtering performance enables the duplex filter (4) to be smaller and less costly.

Abstract: A method allows analog device model descriptions to be described in a suitable language and then automatically converted into the language of the simulator in a form that facilitates gradient-based calculations. The method can include the steps of: entering a high-level description of the component model by naming the model, declaring parameters, specifying argument-independent equations, describing a topology of the model, declaring arguments, and specifying argument-dependent equations. Then, compiling the high-level description to produce model behavior code parse trees and model structure data, analyzing the data-flow of the model behavior code parse trees to produce verified parse trees and error messages for those variables referenced but not defined, debugging the model behavior code parse trees and model structure data, translating the verified parse trees to produce scalar-code parse trees according to a selected translation mode, the scalar code parse trees including objects that manipulate expressions containing derivatives with respect to an argument, checking the argument dependence of the scalar-code parse trees to produce repartitioned scalar code parse trees, and filling in the data required by simulator model templates to convert the repartitioned scalar code parse trees into code in the computer programming language used by the simulator.

Abstract: The present invention relates to methods and apparatus for encryption and decryption, respectively, of digital sound in television. The decryption takes place in two steps. The first step, encryption with running key, is achieved by adding modulo 2 a pseudo random sequence to the digital signal containing a sound information. The pseudo random sequence is preferably generated by a non-linear feedback register initialized by the control word. The second step involves encryption of the control word, thereby being transmitted to the receiver in ciphered form. The encryption is preferably achieved by a microprocessor also performing coding of the control word for forward error correction. The control word in turn is generated by a true random sequence generator. The invention enables an encryption that is secure against breaking without deteriorating the sound quality and also enables efficient handling of the key of the encryption.

Abstract: Disclosed is an image processing apparatus where plural line memories (6-10) store first image information corresponding to a first recording density based on input image data for plural lines, and a logical circuit included in a decision circuit (15, 16) determines a pixel data to be interpolated corresponding to the pixel position of second image information when the first image information is converted to the second image information in accordance with the stored first image information for plural lines. A logical circuit also included in the decision circuit detects a predetermined pattern in accordance with the stored image information for plural lines when the pixel data to be interpolated is determined, calculates a logical expressions for predetermined pattern diffusing processing, and determines a value of the pixel to be interpolated to diffuse the predetermined pattern in the second image information. With the above structure image information for a lower recording density is converted to information for a higher recording density, where half-tone images in high quality can be obtained.

Abstract: Solvents for salt-gradient anion-exchange separation of nucleic acids, especially double-stranded DNA and especially by liguid chromatography, are improved by replacing NaCl as the eluting salt with any of a wide range of alkyl ammonium salts and can be used to elute nucleic acids in strict order of increasing length, with reduced sensitivity to elution temperature and salt concentration. Anion-exchange chromatography with these solvents is well suited for identification of DNA fragments on the basis of size, with greater accuracy, precision, and resolvable size range than often is possible with gel electrophoresis.

Abstract: A data storage system using a moving storage medium quickly measures and accurately compensates for thermal and mechanical errors in the position of the data detector with respect to the written data. This is accomplished by measuring the error rate of the written data as a function of the read offset of the detector. Error rates become increasingly large as the sensed noise to signal ratio becomes large. The number of errors detected in reading written data for various read offsets when the data storage system is initially activated is counted. When the number of errors reaches a target rate, the read offset required to produce the target rate is saved. This procedure is performed on either side of the data track. The detector is then centered between the two offsets. During the operation of the storage system, thermal and mechanical errors are introduced into the detector position compensation means. The present invention compensates for this by periodically determining a new offset for each side of the data track. The new offset which corresponds to the target error rate is found by interpolating between measured offsets for error rates which are higher and lower respectively than the target error rate. The new measured read offsets are obtained by reading back written data in a similar manner as was used to obtain the initial read offsets. The detector is then recentered with respect to the write transducer position between the new offsets on either side of the data track.
