Abstract: A small-sized, high-efficiency semiconductor amplifier exhibits a satisfactory efficiency characteristic over a wide band and a low output level for secondary and tertiary higher harmonics. The semiconductor amplifier is equipped with an output circuit which is composed of a parallel resonance circuit for the secondary higher harmonic of the fundamental-operation frequency, a first connection line, a second connection line, and an open-end line having a length corresponding to approximately 1/4 of the wavelength of the tertiary higher harmonic, the drain terminal of FETs leading to the output circuit being connected to one end of the parallel resonance circuit through the first connection line, an open point being formed at one end of the parallel resonance circuit, the other end of the parallel resonance circuit for the secondary higher harmonic being connected to the open-end line having a length corresponding to approximately 1/4 of the wavelength of the tertiary higher harmonic through the second connection line, the length and width of the first connection line being adjusted to determine the secondary-higher-harmonic load-reflection coefficient of the FETs as seen from the drain thereof to such a value as will maximize the efficiency of the amplifier, the length and width of the second connection line being appropriately adjusted so as to adjust the impedance matching conditions with respect to the fundamental wave.

Abstract: The invention relates to a defibrillation system with a defibrillator connected to at least two defibrillation electrodes, with at least one defibrillation electrode being provided for intracardiac placement. This defibrillation electrode comprises a flexible electrode cable having at least one elongate, electrically insulated conductor and an electrode head which is fitted at the distal end of the electrode cable and has at least one defibrillation surface for transmission of defibrillation pulses to the heart. The defibrillation system furthermore comprises control means which decide when the defibrillator is to emit one or more defibrillation pulses. In order to obtain a defibrillation system with an intracardiac defibrillation electrode of this type whose defibrillation surface is comparatively large and can be distributed in the heart such that damage to the heart is avoided and that it is simultaneously possible to achieve optimum defibrillation, and in which the defibrillation electrode should not influence the cardiac blood flow during the period in which it does not emit any stimulation pulses, it is proposed, according to the invention, that the electrode head (14, 17) be constructed such that it can be expanded and that the defibrillator (1) comprise control means (7) which influence the electrode head (14, 17) via the electrode cable (4, 5), if and when required, in such a way that it expands. <IMAGE>

Date May 30, 1996In the determination of deviation from a concentric position for a protective polyimide coating disposed on an optical fiber, the absorption of light in the coating is used. A light source such as a laser provides a light ray which is split by a beamsplitter in two light rays. By suitably placed mirrors, the light rays are guided to hit two opposite sides of the fiber at oblique and equal incidence angles to the longitudinal direction of the fiber. The light rays hit the fibers at positions which are a little displaced in the longitudinal direction of the fiber in order to prevent wrong light rays from hitting the detectors which receive the reflected light. The detectors provide signals representing the intensity of the reflected light to a subtraction circuit which forms the difference of the signals from the detectors. The different signal is then a measure of the concentricity error of the coating. A simple method and device are obtained in this way which can also be used on-line in the determination of concentricity in the case where the coating is extruded in a drawing tower where the fiber is produced. Absolute determinations of the thickness of a coating can also be made by making a measurement on a fiber having a calibrated coating.

Abstract: A self-adjusting quadrature modulator and modulation method improve the accuracy with which digital data is impressed on an RF carrier, which is particularly useful for systems having Viterbi, echo-integrating demodulators and for systems using subtractive CDMA techniques. The method and apparatus involve receiving one's own transmission with a suitable modulation assessment receiver and determining the modulation error relative to the theoretically perfect transmission expected by the receiver. The measured error is used to adjust the modulation to minimize the error. The modulation assessment receiver may use log-polar signal processing to measure phase and (log)amplitude instead of cartesian I and Q components, and then convert to cartesian form. In addition, correction factors determined by the modulation assessment receiver can be directly identified with certain transform components produced by the Fast Walsh Transform.

Abstract: A method for detecting a leaking nuclear fuel element amongst several of these elements (4) which have been lowered into a liquid (5) such as water, involves testing the elements one after the other in a sequence. During each detection operation the liquid around the element is sucked up and its gaseous contents are separated for analysis in a testing unit (22-38) in order to detect and measure any gaseous fission products.In the testing unit the amount of gaseous fission products normally present in the liquid is measured in relation to the gases normally present in this liquid. In an uninterrupted sequence the amount of fission products in the liquid around each successive element is measured until a leaking element is detected when a relatively high fission product concentration is recorded, following which the testing unit is cleaned out so that the measuring sequence can be continued until all the elements have been tested. The apparatus used for carrying out this method is also claimed, comprising a signal processing and regulating circuit (33) for controlling a liquid suction device (13), normally keeping it active unless a leaking element is detected, in which case the circuit deactivates the suction device in order to clean the testing unit before the device is reactivated to continue the detection sequence.

Abstract: The position of the phone is calculated taking into account the speed of which it is travelling through the cell, by calculating the speed according to the difference in positional data supplied to a sequence filter by two or more sensors.  At least one of the sensors is used to provide data for the speed with which the phone is moving through the cell, and the actual data used to record the position of the phone is based on figures for the speed gathered from two position sensors. An Independent claim is also included for the sensor system (300) used, which contains two or more sensors (301, 303), each sensor being provided with at least one suppressor unit (307, 308) and at least one processor unit (309, 311; 310, 312). Information from the sensors is combined in a sequence filter (305) in order to provides the position of the phone. The processor units supply the sequence filter with the calculated speed at which the phone is moving away from at least one of the sensors, and they also calculate the speed at which the filter is supplied with information on the position of the phone.

Abstract: A method and a device and system in which a torque applied to a bolt, screw or other fastener in a screw threaded joint using a pulse driven torque wrench is estimated. The pulse driven torque wrench is arranged with means for sensing torque applied by the pulse driven torque wrench, also with signal processing means and with control means to control the drive means. The present invention comprises memory and calculation means so that parameters may be calculated from measurements of torque applied. The applied torque is estimated from calculated parameters that describe the form of each pulse, enabling the applied torque to be accurately estimated. The main advantage of the invention is that it provides an accurate and consistent estimate of applied torque. It is also particularly fast and economic to use because no reset or re-calibration is needed for higher or lower torque values and for different fastener/joint combinations. The mode or rate of shut-off also may be pre-determined to suit the type of joint.
