Title: Method and apparatus for determining blood pressure
Inventor: BAKER PHILLIP D
IPC: A61B5/0215
Filed: 1991-08-29
Abstract: A method and device for indirect, quantitative estimation of blood pressure attributes and similar variable physiological parameters utilizing noninvasive, indirect techniques. The method of practice includes (i) generating a sequence of signals which are quantitative dependent upon the variable parameter, (ii) transmitting and processing the signals within a computer system and associated neural network capable of generating a single output signal for the combined input signals, (ii) invasively determining an actual value for the parameter concurrent with the noninvasive generation of signals of the previous steps, (iv) applying weighting factors within the neural network at interconnecting nodes to force the output signal of the neural network to match the true value of the parameter as determined invasively, (v) recording the input signals, weighting factors and true value as training data within memory of the computer, and (vi) repeating the previous steps to develop sufficient training data to enable the neural network to accurately estimate parameter value upon future receipt of on-line input signals. Procedures are also described for preclassification of signals and artifact rejection. Following training of the neural network, further invasive measurement is unnecessary and the system is ready for diagnostic application and noninvasive estimation of parameter values.

Title: Speech coding system
Inventor: SERIZAWA MASAHIRO
IPC: G10L19/12
Filed: 1993-02-23
Abstract: An input speech signal is splitted into a time section and generating the splitted signal as a speech vector and LPC coefficient sets are developed by linear prediction analysis for every time section of the speech vector. The speech vector is weighted based on the developed LPC coefficient sets, then a plurality of the weighted speech vectors are connected and the connected speech vector having a predetermined frame length is generated.          An excitation codevector whose weighted synthesized signal is the most similar to the weighted speech vector is determined among from a plurality of excitation vectors each having the frame length which are previously stored as a sound source. A plurality or adaptive codevectors each having the frame length and obtained by cutting out a sound source signal produced from the determined excitation vectors at predetermined timing points are stored in an adaptive codebook. An adaptive codevector whose weighted synthesized signal is the most similar to the weighted speech vector is determined among from the plurality of adaptive codevectors.

Title: Controllable polarisation transformer
Inventor: VAN DER TOL JOHANNES J G M
IPC: G02F1/025
Filed: 1993-03-26
Abstract: Controllable polarisation transformer comprising a passive mode converter (4), a controllable phase shifter (5) and a controllable Mach-Zehnder interferometer (7). The mode converter (4) converts the first signal component of one polarisation (TE or TM) of a light signal entering via an input (1) into a signal component of the other polarisation without affecting the second signal component of the other polarisation (TM or TE), the conversion taking place to another order of the guided mode. Phase control by means of the phase shifter (5) controls the intensity distribution of the light signal over the two branches (8, 9) of the interferometer (7). Optical wavelength control in the interferometer (7) controls the phase with which the signals through the branches come together in the output (2). Advantages: very good integration capability, preferably on semiconductor material, with a waveguide structure which can be achieved in a single etching step and without critical manufacturing parameters; can be used reciprocally, even as a polarisation modulator.
