Title: Method for influencing the organism
Inventor: LEVIN YAKOV IOSIFOVICH
IPC: A61B5/374
Filed: 1996-12-26
Abstract: The method relates to the generation of external sound influence by generating musical sounds. The parameters of pitch, volume, and length of these sound, are modified in accordance with the criteria changes in the discrete-current value of a distinctive generalised parameter of the frequency spectrum of a converted biosignal, that is, the bioelectrical potential. Thus, from recorded graphical information concerning bioelectrical activity, time intervals of a same duration are isolated and converted into a frequency spectrum using Fourier's method. A generalised non-dimensional parameter is then determined for each spectrum interval; in the numerical interval between the minimum and the maximum values of this parameter, a scale is constructed that is proportional to the parameters of the musical sound; the corresponding parameter values of the musical sound are then determined for each spectral interval on the basis of the numerical value of the generalised parameter; these corresponding values are then converted by means using a sound card into sound signals generated in a sequence corresponding to the initially recorded alternation of time intervals. The generalised non-dimensional parameter can be determined in relation to the power spectral densities of at least two distinctive frequency ranges isolated in each spectral interval.

Title: Network distributed system for updating locally secured objects in client machines
Inventor: BAHR TERRY S
IPC: G06F21/00
Filed: 1998-03-11
Abstract: Technique for allowing real time centralized administration of protected objects on client computer systems. When a user logs on to a centrally administered clients machine on a computer network, an intermediary object modification process starts in the background with administrator account permissions. Thereafter, whenever the administrative agent on the client computer system unsucessfully attempts to perform an operation on a protected object for which the logon user lacks sufficient permission to perform (218, 220), the agent passes a request (226, 312) to the intermediary process to perform the operation. The intermediary process is able to perform the desired operation because it has sufficient permission to do so even if the administrative agent does not.

Abstract: An arrangement is disclosed for providing equipment 1 x N protection switching in a communications network element or system having a plurality of working port units that process communication signals passing between a first and a second location, having a backup port unit that is used to replace a defective one of the working port units, having a protection switch unit that switches the backup port unit for a defective working port unit, and having a controller for monitoring the operational status of the working port units and upon determining that one of the working port units is defective initiates the switch of the backup port unit for the defective working port, wherein the communication signals are not sent from a working port unit to the protection switching unit and thence to the backup port unit until the working port unit is determined to be defective, thus reducing crosstalk at the protection switching unit, and after the switch is accomplished a verification signal is sent back to the controller that all switching has been accomplished and the backup port is processing the communication signals that had been processed by the defective working port unit. The controller initiates the switching process using the backup port unit which in turn signals the protection unit to connect the signals from the defective working port unit to the backup port unit, and the protection switching unit then forces the defective working port unit to switch the communications signals it had been processing to the protection switching unit. In the event that the defective working port unit has no electrical power the protection switching unit temporarily provides power thereto until it is forced to transfer the communications signals to the protection switch unit for processing by the backup port unit and until the defective working port unit has been replaced.

Filed: 1995-09-20
Abstract: The present invention relates to a method of determining the flow rate and direction of a medium within a conduit. The method is comprised the steps of coupling a pair of sensors to the conduit at a first and second location thereof. A first vibration is imposed upon the conduit at a position proximate a first sensor in the pair of sensors, the position being outside of a region located between the pair of sensors which are separated by a distance and mounted to the conduit. A first transmitted vibration is detected, propagating along the conduit in response to the imposed vibration at both sensors.      The above defined steps are repeated wherein a second vibration is imposed at a second location proximate a second sensor in the pair of sensors, the position being outside of said region located between the pair of sensors. The center velocity of each transmitted vibration is determined by computing an envelope correlation function. The direction of fluid flow and the velocity of the medium within the conduit is then calculated.

Filed: 1998-06-17
Abstract: A silicon substrate material based on silicon has a semi-insulating interior layer (5) isolating the bulk of the substrate material from the top layers (7), where integrated circuits are to be built. The semi-insulating layer is created by producing submicron particles having Schottky barriers or pn-hetero-barriers and distributing the particles so that the depletion regions then produced around neighbouring particles overlap. Such particles will then deplete the silicon material from electric charge carriers. The substrate material can then be processed using the standard silicon processing methods and allows integrated circuits to be manufactured which are suitable for high frequency applications. A silicon substrate is made by sputtering a metal such as Co in a silicon wafer (1) and then silicidizing the sputtered Co atoms by means of an annealing treatment. A top silicon wafer (11) having a silicon dioxide layer (13) at its bottom surface is then bonded to the sputtered layer. Finally the top wafer (11) is thinned to provide a layer thickness suitable for the processing steps required in the manufacture of components.

Abstract: Improved transmission or storage of signals, such as high speed transmissions in subscriber loops of telecommunication systems, is facilitated by apparatus which includes an encoder (12) for encoding the input signal (I) before application to the transmission/storage medium (13) and a decoder (17) which decodes the signal received from the medium. The encoder comprises an analysis filter bank (21) which analyzes the input signal (I) into a plurality of subband signals (S0, S1, ...), each subband centered at a respective one of a corresponding plurality of frequencies; and a device (22) for combining a plurality of the interpolated subband signals to provide an encoded signal in which the interpolated subband signals occupy the same frequency band. The interpolated subband signals may be combined using QAM, CAP or DMT. The decoder (17) extracts the interpolated subband signals from a received encoded signal; and applies them to a synthesis filter bank, complementary and substantially inverse to the analysis filter, which processes the extracted interpolated subband signals (I') to produce a decoded signal corresponding to the input signal.
