A method and apparatus wherein a Genetic Algorithm or an Evolutionary Program is used as an intelligent search technique addresses the problem of assigning sensor reports in multi-target tracking with one or more sensors. The inventive technique of tracking objects includes receiving sensor reports from at least one sensor over multiple time scans; formulating hypotheses as lists of associations between the sensor reports; constructing at least one track for each of the hypotheses; scoring each of the hypotheses; searching through a portion of the hypotheses, using an intelligent search algorithm, to find a good hypothesis; and determining the state of the tracked objects.

In a system for managing medical information by using a hybrid card having an optical stripe and an IC module, in a hospital there is provided a main data processing apparatus which can write and read data on and from the optical stripe of the hybrid card and can write and read data from the IC module, and in a patient's home there is arranged a sub data processing apparatus for reading and writing the data on and from the IC module. The patient measures blood pressure and heart rate at home, and the measured data is recorded on the IC module. In the hospital the blood pressure and heart rate stored in the IC module are read out and are used for diagnosis. As the sub data processing apparatus installed in the patient's home could not write data on the optical stripe, the apparatus can be made small in size, simple in construction and cheap in cost. Further, the important data stored in the optical stripe could not be erased or altered by the patient. The sub data processing apparatus may be formed to read limited data stored on the optical stripe.

Method of operating, catheter and catherization system for measuring electrical impedances in blood vessels, within a annular area around the catheter. The catheter contains excitation electrodes, between which the impedance is measured through a potential difference between measuring electrodes present between those electrodes.Around the catheter a pattern of electrical field lines is created, a so-called counter current field, by varying the amplitude of the currents it being provided that between the measuring electrodes no or hardly any current runs and that at a larger distance of the measuring electrodes the electrical field lines are mainly perpendicular to the longitudinal axis of the catheter. The average impedance of the area to be measured and that of the area outside this will be measured separately. The current intensities then will be chosen such that their relation deviates from the one, at which there is no current between the measuring electrodes--the quenching relation--respectively by adjusting exactly on the quenching relation.

Methods and apparatus for transforming input image data representing an image to produce output image data representing a transformed image are provided. Input image data is stored in a first memory in the form of input data blocks. Read addresses for reading the data from the first memory are produced in order to yield transformed data blocks each representing a portion of the transformed image. A depth value and depth gradients with respect to orthogonal directions of the transformed image are produced and, from these, a depth value for each pixel of each transformed data block is produced. Depth values of pixels of the transformed data blocks having the same position in the transformed image are compared to produce write enable data for storing the read addresses in a second memory, so that read addresses for data relatively closer to the point of view overwrite addresses of hidden data. The read addresses are read from the second memory circuit to the first memory circuit in order to read out the image data to produce the transformed data blocks.

The method and apparatus of the .present invention presents an apparatus and-method for block adaptive image compression. The method and apparatus of the present invention reduces data storage and transmission requirements by sending a subset of the entire pixel data set existing in an image pixel data set. The pixels that are stored are referred to as primary pixels. The remaining pixels that are not transmitted or stored are referred to as secondary pixels. These secondary pixels are estimated from the primary pixels. A high fidelity image can be reproduced utilizing only the primary pixels. The method and apparatus of the present inventions estimates the secondary pixel values from the primary pixel values by predicting that a secondary pixel will look like the surrounding primary pixels, or by interpolating a value for the secondary pixels by summing the surrounding primary pixels and averaging them to obtain a value for the secondary pixel.

The present invention provides an interneuron crossrelation identification technique and an interneuron connection-structure estimation technique for inferring a connection-structure and the strengths of the connectivities among a plurality of neurons required for constructing a neural network model, by obtaining crossrelations among time-course data of neurons. The interneuron crossrelation detection technique may include steps of: calculating conditional probabilities by, among other things, normalizing crosscoincidence histograms calculated from time-course data of activities of the neurons representing a train of action potentials of the neurons representing a train of action potentials of the neurons, and comparing trains of symbols representing time-course states of the activities of the neurons; distinguishing an inhibitory connectivity form an excitatory connectivity by comparing the conditional probabilities to each other; and quantitatively estimating the magnitude of crossrelation among the time-course data. The interneuron connection-structure estimation technique may include steps of: computing conditional probabilities by normalizing cross-coincidence histograms calculated from time-course data of activities of the neurons representing a train of action potentials of the neurons; computing conditional mutual information and three-point mutual information from the computed conditional probabilities; and inferring a connection structure among the neurons.

Method and system for remote monitoring of high-risk patients using artificial intelligence. A plurality of high-risk patients can be simultaneously monitored without patient intervention. A patient hears questions in the doctor's voice at each monitoring encounter and responds. The patient's responses are recorded at a remote central monitoring station and can be analyzed on line or later. Artificial intelligence (AI) and voice technology (DECvoice) are combined to present to the patient, during a monitoring session or encounter, questions which would be selected from a plurality of different recorded questions. Questions to the patient are chosen using AI, based on the patient's response, by parsing. The monitor could take several forms such as for e.g., uterine activity strips, glucometers, blood pressure cuffs, pulse monitors, electroencephalographs, etc. Preferably, four telephone lines are dedicated to each patient, one for the monitor, one for the voice, one as a back up and one to sense failures. Dual tone matrix frequency signals (DTMF) may be used for transmission of monitored signals and other information which can be recognized by DECvoice, which is but one example of the voice technology which can be used.

An image filing apparatus comprises a drive device which is loaded with an optical disk capable of storing a plurality of signals, and with which image signals representing images and subsidiary information belonging to each of the images are stored on the optical disk and read therefrom. When the image signals and the subsidiary information corresponding to each of the image signals are stored on the optical disk loaded into the drive device, a data base constructing device constructs an image signal retrieving data base from the subsidiary information such that an image signal corresponding to the subsidiary information may be retrieved. A storage device stores the data base such that it can be rewritten. A data base construction preventing device inspects the subsidiary information when an image signal and the subsidiary information corresponding to the image signal are stored on the optical disk loaded into the drive device. In cases where the subsidiary information has been found to be abnormal, a data base is prevented from being constructed from the subsidiary information.
