Abstract: A method and apparatus for evaluating the insurability of a potentially insurable risk has data bases for storing information, and the ability to correlate selected elements of information in respective data bases. Certain elements are assigned weights on the basis of predetermined relationships existing between elements of information in one data base and corresponding elements of information in another. Information is displayed from a data base for use by an underwriter in assigning a weight to a selected element, or an expert module corresponding to the selected element is identified and used for assigning the weight. A risk classification is determined for the potentially insurable risk from the weights assigned. The system can identify additional elements of information required for evaluating the potentially insurable risk, and can request entry of such information for subsequent storage.

Statically validated threshold levels are used for comparison with the decision variables to determine the probability of normal and ischemic conditons.

Abstract: A system and method for the inventory of physical assets utilizes a digital computer based system including work station terminals each having an interactive graphics display screen in which the information displayed on the display screen may be graphically altered by the user. Inventory designation data may be obtained by a hand-held laser reader from a bar code label affixed to the item. Absolute geographic location data in terms of latitude, longitude and elevation, each within one foot of accuracy, is associated with each inventory item and with its designation data.

Abstract: A processing system manages investments, wherein certain types of investments are represented in two redundant media, the first media being an investment that produces revenue and the second media being a negotiable draft similar to a traveler's check, drawn against an issuer other than the investor. The processing system supervises the issuance of drafts in response to the addition of a first media investment to an investment account, permits issued drafts to be transferred between account holders and to non-holders, and supervises buy and sell orders relating to each account to ensure that an appropriate balance of values is maintained between the first and second media investments in each account such that each outstanding draft is supported by a first media investment.

Abstract: An ultrasound blood flow imaging system employing a moving-target-type Doppler processor having a passband extending from zero hertz to the repetition frequency of the pulses generated and processed during each beam. The system is able to image low-velocity blood flow by reducing the frequency at which pulses are generated and processed during each beam, thereby increasing the gain of the flow processor at low frequencies. In order to avoid a corresponding decrease in the frame rate, the ultrasound pulses for several beams are alternately generated and processed in interleaved sequence rather than generating and processing all of the ultrasound pulses for each beam before generating and processing ultrasound pulses for the next beam.

Abstract: Malfunctions of the cardiovascular control system may be diagnosed by examination of a patient's heart rate fluctuation power spectra. Particularly indicative of cardiovascular stress are: a level below about 0.1 (beats/min.).sup.2 in the power spectrum of heart rate fluctuations at a frequency between about 0.04 and about 0.10 Hz; a marked increase to above about 10 (beats/min.).sup.2 in a peak in the heart rate fluctuation power spectrum between about 0.04 to 0.10 Hz; and a ratio of the area under a heart rate power spectrum peak at a frequency between about 0.04 and 0.10 Hz to the area under a peak in the respiratory heart rate fluctuation power spectrum centered at the mean respiratory rate about about 0.10 Hz as having an absolute value less than 2.0 for longer than or equal to about one hour or as having an absolute value greater than about 50.

The system comprises as a central processing unit a command computer (4) structured on the basis of a permutograph and comprising a plurality of storage modules (M), with the storage modules (M) corresponding to the elements and the connections between the storage modules to the edges of the permutograph.

Abstract: A monochrome image of a cross-section of a body and a color representation of the velocity of blood flow therein are combined so that they are mutually exclusive by causing each pixel of a display to be in monochrome when a signal from which a velocity indicative signal may be derived is less than a minimum value or when that signal exceeds the minimum value and a weighted value of the velocity indicative signal is less than a weighted value of the signal for the monochrome image, and to be in color when the signal from which a velocity indicative signal may be derived exceeds the minimum value and a weighted value of a signal indicative of velocity exceeds a weighted value of the signal for the monochrome image.

After the tickets have been retrieved at terminal ends or stations of the transportation routes, the information is read from the tickets, and the transportation entities are billed for ticket fares or fare differences calculated on the basis of the read information.

Abstract: An improved medical diagnostic imaging method and apparatus. In both, Nuclear Magnetic Resonance and Computed Tomography imaging artifacts caused by the finite number of directions from which imaging data is obtained is minimized. An image is constructed and then modified by adjusting each image element with contributions from neighboring picture elements. When all picture elements have been so modified an improved image approximating a result that would have been achieved by interpolating and then reconstructing image data is obtained.

Abstract: The transfer of the temperature of a body to a fertility calculator (7) is only authorized by the time controller (20, 23) when a first counter shows that a first preselected period of time (e.g., 22 hours) has elapsed since the previous temperature measure and when a second counter (23) shows that the temperature is being taken during a second preselected time interval (e.g. 4 hours) following the first period of time. Accordingly, only one measure can be made per day at approximately the same time, thereby eliminating the important problem encountered when the temperature is taken at irregular intervals.
