Abstract: FIELD: measuring equipment. 
     SUBSTANCE: invention relates to measurement equipment, namely to methods and facilities intended for measurement of liquid flow rate, and can be used in various industries for purposes of control, regulation and accounting of medium flows. In particular, the invention can be used for determination of liquid flow rate in a well by a vortex flow meter under conditions of action of low-frequency vibration loads. Method of determining liquid flow rate consists in continuously receiving a signal which includes a useful frequency component which characterizes the velocity of the liquid flow and a noise frequency component which characterizes the intensity of vibration. PT signal obtained at the current moment of time is digitized and placed into the spectrum. Vibration sensor measures vibration, digitizes the measured VS signal and spreads it into a spectrum. Further, the useful signal spectrum is picked up by subtracting the signal spectrum VS from the spectrum of the PT signal. Derived spectrum of the useful signal is used to calculate the vortex generation frequency from which the fluid flow rate is determined, which determines the flow rate of the liquid at the current moment in order to transmit information on the determined liquid flow to the consumer. Vortex flow meter configured to supply voltage to power-requiring elements and comprising series-connected primary transducer (PT), processing device (hereinafter, PD), vibration sensor (further, VS). PD is configured to decompose in the spectra of the digitized PT signal and the VS signal, extracting the useful signal spectrum from the PT signal spectrum, application of a useful adaptive filtration signal in the form of a Hamming Window to the said selected spectrum and evaluation of weight functions, calculation of the vortex generation frequency, calculation of the liquid flow rate value at the current moment in time, automatic adjustment of the PT signal level, filtration of its low frequency. 
     EFFECT: high accuracy of determining the frequency of vortex formation, especially during strong vibration action due to: higher vibration stability of the vortex flow meter, possibility of excluding false measurement of flow rate and increasing the minimum measured level of flow rate in conditions of influencing the flow meter of dynamically varying vibration loads.

Abstract: Methods and apparatus for exchanging frames between bridges distribute load sharing in a communications network. The communications network is of the kind in which bridges, and related stations and local LANs, e.g. Ethernet LANs and 802 LANs, can be linked by paths in a plurality of sub-networks and wherein the bridges are linked to support a Spanning Tree Protocol (STP) which elects one bridge as a root and then with respect to said root, computes and utilizes one and only one loop-free set of primary paths between all bridges. Remaining paths, i.e. paths other than said STP primary paths, between the bridges are examined as possible sub-network paths for a Distributed Load Sharing (DLS) configuration in which frames exchanged between certain stations can utilize more than the STP one set of primary paths. Certain ones of the remaining paths are selected as DLS paths under certain conditions and frames are routed over a selected DLS path only when those frames meet certain criteria.

The simulated call setup is initiated by generating a modified short message signal (SMS) which is not registered in the SMS catalogue of the mobile station and which is not shown to the user of the mobile station. The SMS commands the mobile station to carry out a position determining sequence in order to establish parameters for use in establishing the position of the mobile station, for example by commanding the mobile station to connect itself to a base station contained in its neighbor list, analyze the geographical position of the base station, and subsequently send the position determining parameters to a position handler. The geographical position of the base station is analyzed from the cell identity and, if available, the timing advance, the position of the mobile station being presented graphically on a picture screen and constantly updated after each call setup.
