Abstract: A speech quality estimation technique that employs an arbitrary, speech quality estimation algorithm. The speech quality estimation technique analyzes a reference speech signal and a test speech signal, and based on this analysis, identifies the level of continuous delay variation, if any, and the location of and size of any intermittent delay variations along the test signal. The reference speech signal and/or the test speech signal are adjusted to account for continuous delay variation and intermittent delay variations, such that the reference speech signal and the test signal are similarly scaled with respect to the time domain. The reference speech signal and the test speech signal are then compared for the purpose of generating a speech quality estimation. The resulting speech quality estimation is then adjusted based on the level of continuous delay variation and any intermittent delay variations.

Abstract: An improved method and system of measuring the perceived speech quality in mobile telecommunications networks is disclosed herein. In an embodiment of the invention, the method uses both radio link parameters and an objective measuring technique performed on received signals to estimate the speech quality perceived by the end-user. A radio link processing stage extracts temporal information from a set of available radio link parameters such as the BER, FER, RxLev, handover statistics, soft information, and speech energy. Concurrently, a speech processing stage is used to process a sequence of original signals and received signals, obtained from the output of a telecommunications system. The signal sequences are processed by an objective measuring technique such as Perceptual Speech Quality Measure (PSQM). The outputs from the radio link processing and speech processing stages are utilized to calculate an estimate for speech quality.

Abstract: A method and system for measuring the speech quality in a mobile cellular telecommunications network using available radio link parameters is disclosed herein. In a preferred embodiment, the method includes receiving a set of radio link parameters, as defined in a standard or otherwise available, such as the BER, FER, RxLev, handover statistics, soft information, and speech energy. Temporal information is obtained from the radio link parameters to create a set of temporal parameters which can be statistically analyzed, for example, for the maximum and minimum, mean, standard deviation, and autocorrelation values for a time interval. The temporal parameters are combined to yield a set of correlated parameters that are more closely related to the speech quality. An estimator then uses the correlated parameters to calculate an estimate for the speech quality. The method of the present invention takes advantage of temporal information and correlated relationships from the transmitted parameters.

Abstract: A microwave switch having a switch housing with side walls in which waveguide connections are arranged; a switch rotor rotatably arranged in the switch housing; a drive means arranged on the switch housing with a shaft for providing a moment for rotating the switch rotor; and a transmission arrangement arranged to transmit the moment of the drive means to the switch rotor. The transmission arrangement has a first link with a radially extended slot, and a second link fixed to the shaft and fitted with a guide member arranged to be slidably moved in the slot. Further provided is a first stop member fixedly connected to the switch rotor and arranged, in the respective switch position, to engage with a second stop member fixedly connected to the switch housing; and a means arranged to apply a torque to the switch rotor in order to press the stop members against each other.

Abstract: A second-step virus binding receptor is found in nature on the surface of animal and plant cells. This receptor is thought to be needed for virus penetration into target cells. The second-step receptor has been found to bind a wide variety of viruses belonging to a number of different families. The second-step receptor and natural or synthetic substances which correspond to or are analogous to the binding epitope of the second-step receptor in that they are able to bind to a site on the virus which recognizes the binding epitope of the natural second-step receptor, are therefore indicated for the diagnosis, prophylaxis or treatment of viral infections.

Abstract: A method for phase-locked sampling measurement of a periodically varying quantity. The samples are designated g(I) . . . g(I-n) and may comprise one complete period or a half of one period. The method involves adapting the sampling frequency and the sample position in relation to the quantity to be measured such that phase locking is attained, and this is done by controlling the time interval between sampling. Whether the sampling frequency needs to be increased, left unchanged or be decreased, depends on a number of decisions depending on the values of samples g(I) and g(I)-g(I-n). A device for carrying out the method is also described.
