Title: Extrapolating ica knowledge from one epoch to another for fetal ecg separation
Inventor: KOLLURI SAI
IPC: A61B5/288
Filed: 2009-02-12
Abstract: A method of utilizing a maternal-fetal monitoring system to monitor the physiological properties of both a maternal patient and a fetus. A series of electrocardiogram (ECG) electrodes are placed across the maternal patient's abdomen and receives ECG input waveforms across sixteen separate channels. The sixteen channels of information are processed using an independent component analysis (ICA) algorithm to generate a series of ICA output waveforms and a transfer matrix. Following the current epoch, the transfer matrix is applied to the input waveforms on a continuous basis. The conditioned input waveforms are displayed immediately following the first epoch and prior to the expiration of a subsequent epoch. The transfer matrix for the second epoch is combined with the transfer matrix for the first epoch to generate an updated transfer matrix. Various filtering operations on the transfer matrix coefficients may be used to find the updated transfer matrix before the end of the current epoch.

Convention dates, April 2, 1932 and Feb. 7, 1933. [Class 20 (ii).] A vibration neutralizer for ships and other structures comprising a massive body supported by an elastic system such as springs in a framework which is attached to the vibrating structure is characterized by the provision of manually operable means for enabling the effective mass of the body to be adjusted at will. The massive body takes the form of a tank 1, Fig. 1, disposed between upper and lower frames 35, 36 which are connected at their corners by tie rods 38. The tank carries guiderollers 39 which bear against the tie rods and is supported elastically between the frames by sets of single or double spiral springs 32 which bear against the frames and against a rib extending along each side of the tank. Internally the tank is provided with diaphragms, partitions or tubes which act as baffles to prevent surging of the water with which the tank is filled to the required amount. Inlets 8 and outlet 10 for the water are provided enabling adjustments of the water content of the tank to be made at will. When horizontal vibrations are to be neutralized, the tank is mounted on horizontal runners and the springs are correspondingly arranged. In a modification, Fig. 15, the main portion of the massive body is cellular in structure and the water content is supplemented by weights which are introduced into lateral chambers 232, 233 a layer of wax being poured over the weights to prevent their bumping. Excessive movements of the massive body are checked by spring-pumpers 293 coming against limit stops 204.

Abstract: 1494001 Controlling light COMPAGNIE GENERALE D'ELECTRICITE 11 March 1975 [12 March 1974] 10149/75 Heading G2F [Also in Division HIC] An optical isolator comprises a number of plates 1-3, 6-10 exhibiting the Faraday effect and disposed in series on an axis 25 such that in the presence of a magnetic field B of predetermined amplitude and direction, a linearly polarized beam 20 travelling in the transmission direction is incident on each plate at substantially the Brewster angle and with a polarization direction in the respective plane of incidence (i.e. for plates of identical thickness and Verdet constant subjected to the same field B as shown, each plate is equally inclined to the axis 25 and is rotated about the axis by the Faraday rotation angle relative to the preceding plate), the number of plates, their thickness and material, and the magnetic field B being selected such that the linear polarization direction is rotated by 45 degrees between the first and last plates. Beams propagating in the opposite direction may be considered to be composed of linear polarizations parallel and normal to the plane of incidence at plate 10. The normal polarization is strongly reflected at plate 10, and less strongly at following plates. The parallel polarization is increasing reflected by plates 9 to 1 as its polarization vector moves increasing out of the plane of incidence. As particularly described 10 plates are used and a coil 30 provides the field B. In a modification, Fig. 3 (not shown) alternate plates are rotated by 180 degrees about the line 25 whereby the incident and sintering beams may be parallel to the axis 25. A high power laser may comprise a laser generator, a number of amplifiers, and the isolator in series. By forming the plates of an active material such as neodymium doped glass and providing a flash or other pumping device, the isolator may also function as the last amplifying stage, Fig. 4 (not shown).

Class 20(1) A collapsible hut having a flexible covering 14 comprises a framework of hollow, inflatable members including base stays 11 spaced apart by arch members 13 and cross members 12, and spacers 16 for the arch members. A plurality of deflation valves 17 and non-return inflation valves 18 are provided in the framework, and coiled springs 19 are fitted inside at least the arch members 13, being secured thereto at intervals by clips 20. For storage and transport, the various members of the framework are collapsed, after release of the valves 17, by compressing them axially, thereby compressing the springs 19, and are placed in a valise 15 to maintain them in their collapsed condition. Upon opening the valise, those parts of the frame which are fitted with springs 19 tend to expand under the action of the springs so as to suck in air through the non-return valves 18 and effect some measure of self-inflation, a pump being used, if necessary, to complete the operation of erection. As alternatives to the springs 19, use may be made of wires bent to sinuous form, and capable of being compressed into a spiral form.

In a switch of the type described in the parent Specification in which a magnetic shunt is provided for the contacts, and consists of alternate horizontal and vertical strips, the strips N7, N8 enclosing the ends of the contact springs 12 ... 14 are arranged parallel to the holding coils such as H1. In the parent case these strips were vertical and provided an undesirable magnetic connection between springs associated with H1 and the springs immediately below and associated with a further holding coil (not shown) immediately below H1. As shown, the magnetic shunt portions comprise horizontal strips N3, N4 enclosing a horizontal coil A, vertical strips N5, N6 enclosing a vertical coil C, and horizontal strips N7, N8 enclosing hold coil H1. The strips N5, N6 and N7, N8 are bent inwardly and downwardly respectively to provide a large engaging surface to decrease the reluctance at their points of contact. Strips N3, N4 and N5, N6 are slotted to receive each other and provide a square magnetic cage around each contact set. Magnetic members Zs, Zp may be provided as described in Specification 830,317, dividing each cage into form portions, each portion housing a contact pair of a set of four such pairs. The ends of strips N7, N8 are further bent so as to be adjacent to the ends of the contact springs 12 ... 14 to decrease the reluctance of the circuit. The ends of strips N3, N4 are not so bent, to facilitate withdrawal of the contact sets, but the gap may be filled with intermediate layers of magnetic material.
