Abstract: A method of predicting pore pressures at a proposed drilling location using Interval Transit Times derived from seismic data and Interval Transit Times from a calibrated normal geopressure trend. Seismic Interval Transit Times derived pore pressures and actual pore pressures derived from logs in a drilled well at an offset location are used to correlate graphically or analytically the seismic Interval Transit Times to normal geopressure interval transit times from a proposed drilling location to be used in the prediction of pore pressures at the proposed location.

Abstract: A method and apparatus for reducing the number of errors generated when reading digital data stored on a recording medium such as film, the method comprising passing light of two different frequencies (i.e., two different frequency bands) through the film, one frequency being modulated by digital data stored on the film and the other being unaffected by the stored data. The light that is unaffected by the stored data is modulated by debris on the film such as dirt and is used to flag data bits that may be in error to thereby facilitate an error correction process. In the first disclosed embodiment the two frequencies of light are processed separately to obtain the digital data and error flags. A second embodiment combines all light passing through the film to produce digital information that includes error flags.

Abstract: A method for demarcating a reticulocyte particle group from a red blood cell particle group in a one-dimensional frequency distribution assumes a normal distribution on one side of the distribution. Various positions Xs.sub.1, Xs.sub.2, . . . , Xs.sub.n, which respectively indicate frequencies that are p.sub.1, p.sub.2, . . . p.sub.n percent (where n is an integer of 3 or greater) of a peak frequency of the distribution, on the normal side of the distribution, are determined. An average value and standard deviation of the normal distribution is determined from these values. A threshold value is next obtained from the average value and standard deviation, the threshold value being used to separate the reticulocyte group from the red blood cell group. The average value and standard deviation may be obtained using a least square method or by computing the mean of several average values and standard deviations.

Abstract: An automated ledger account maintenance system provides up-to-the-minute balances in all ledger accounts whenever data relating to a completed transaction is entered. The system is implemented on a general purpose computer and includes a predefined data file structure including ledger account data files corresponding to the ledger accounts and transaction record data files corresponding to transaction journals. Compliance with user definable accounting procedures is ensured through the use of an accounting control table that contains symbolic codes used by the recordkeeping procedures to authorize and control the creation and updating of the ledger account and transaction record data files. Cross-referencing and indexing of ledger account records, transaction records, and the second control records is provided to ensure a high degree of resistance to unauthorized alteration of the data files and to provide for traceability of all entries and postings.

Abstract: In a shared navigable workspace that is presented at more than one workstation, a region is made private in response to a user request. The user can also indicate the region's level of privacy by indicating levels of access of different users. The private region's contents are displayed only to users that have visual access; a non-informative pattern covers the region's area on the displays of other users. The private region and its contents can be modified only by a user with access to modify. When a user requests movement of a pointer into the private region, the pointer can be presented in the private region if the user has sufficient access; otherwise, the pointer would be kept outside the private region's boundary. If a user requests a transition into the private region by selecting a selectable transition unit, called a teleporter, the request would be denied unless the user has sufficient access.

Abstract: A circuit for buffering and parity checking digital data communicated between first and second data buses includes a plurality of bidirectional bit buffer circuits.

Abstract: A computer system for recording patient care results for retrospective analysis in a primary care out-patient environment provides, in the present system, for entry of separate, linked electrocardiographic (EKG) or chest x-ray (CXR) test results (or both) for a database of patients. Entry of the EKG and/or CXR results prompts the creation of a separate lab record, if not already present, which may be holding blood work from the same lab test request. Portions of information entered in the EKG or CXR routine are automatically transferred to the separate lab record. Provision is made for linking the EKG or CXR records to the lab record in both "source" and "non-source" situations; a "source" situation meaning that the lab test request was made formally during an office visit, and a "non-source" situation meaning that the lab test request was made informally, such as by telephone. Two print generation programs pull together various linked data files and selectively print out information contained therein.

Abstract: An asynchronous chip is tested functionally by clocking it at a rate slower than its specified rate while applying test vectors at times selected so that synchronized signals guaranteed on the chip will be predictable. Testing of the chip at the specified rate is accomplished on a section-by-section basis.

Abstract: A method is provided for modifying calculation of a predefined procedure in a spread of financial data in a financial information system operative on a digital computer wherein data is manually input into a cell as a value, the value is prioritized above other values dependent thereon by setting a lock flag to indicate that the data is to be secured against change by subsequent recalculation on the cell and thereafter the data of all other cells which is not locked is recalculated on the basis of the priority values stored in cells designated as locked. In each case, the steps of inputting, locking, recalculating and storing are repeated for each manually entered data value. The value is recalculated upon unlocking a cell, thereby deprioritizing the data.

Abstract: The invention relates to x-ray scanners and more particularly to a method for calibrating scanners by means of a single standard of elliptical shape, for example. Attenuation measurements are performed with respect to a number of principal angular positions of the scanner about the standard. In addition, a number of meaurements or views are taken on each side of this principal position in order to compute a mean attenuation with respect to each channel. The attenuation curve is then smoothed by filtering and polynomial approximation.

Abstract: This rescue administration aid device is a portable unit which may be worn on a rescuer's wrist. It is operative in response to parameter entries by the rescuer according to the victim's condition to provide sequential procedural displays of medical standard rescue steps for assisting the rescuer in carrying out the correct rescue operation. The standard rescue procedure is stored in a microprocessor which, if necessary, can be re-programmed to update to a new rescue standard procedure. It includes a recall feature operative for reverse searching of any desired step in the display if the condition of the victim changes during the rescue operation. Additionally, distinct tone signals are emitted at selected steps of the rescue operation procedure to assist the rescuer in memorizing and conducting such steps in the rescue.

Abstract: A system for automatic collection of tolls includes a toll facility, an in-vehicle toll processor having memory for storing a toll-money-available quantity purchased by the user, and a toll-facility-identification site that transmits a toll-facility-identifier signal indicating the identity of the upcoming toll facility and the toll to be collected. As the vehicle approaches the identification site, the in-vehicle processor receives the identifier signal and calculates the toll be be debited. When the vehicle passes through the toll facility, the facility transmits a toll-collect signal instructing the in-vehicle toll processor to debit the calculated toll from memory. The in-vehicle processor debits the calculated amount and transmits an acknowledgement signal to the toll facility.

Abstract: The approximate elapsed time since the onset of ventricular fibrillation is detected from an analog electrocardiogram signal. The signal is digitized for a time interval of four seconds to obtain a data set of time domain samples. These time domain samples are Fourier transformed to a frequency domain spectrum and the median frequency which bisects the energy of the power spectrum is detected. That median frequency is then compared to a pattern of experimentally obtained median frequency data as represented by a mathematical algorithm to calculate the estimated time from the onset of ventricular fibrillation. This frequency parameter can also be used to evaluate the response to therapy during ventricular fibrillation and CPR, as well as estimate the most appropriate time to defibrillate a subject following various pharmacologic and mechanical intervention.

Abstract: Magnetic Susceptibility Imaging (MSI) comprises a generator to magnetize the tissue to be imaged, such as a first Helmholtz coil, which produces a high-strength external magnetic field to which unpaired electrons of paramagnetic molecules of tissue, which includes primarily deoxyhemoglobin and oxygen, couple in a positive sense, and to which orbital electrons of diamagnetic molecules of tissue, such as proteins and water, couple in a negative sense to produce a secondary magnetic field. The imaging system further comprises a nullifier to null the external magnetizing field, such as a second Helmholtz coil which, for example, confines the flux of both of the coils to a single plane such that the component of the secondary field perpendicular to this plane is the only field with a nonzero component. The secondary field component is detected by a detector, such as an array of Hall voltage detectors.

Abstract: An automated method and system to determine a number of parameters related to the size and shape of the heart as well as parameters related to the lungs from data derived from digital chest radiographs. A cardiac rectangle enclosing the heart and portions of the surrounding lung tissue is determined, and within the cardiac rectangle, horizontal and vertical profiles, and the first derivatives thereof, are determined. Based on these derivatives, cardiac boundary points on the left and right sides of the cardiac contour are determined, as well as diaphragm edge points. A predetermined model function is then fitted to selected of the determined cardiac boundary points to determine the cardiac contour. Tests are performed to determine whether or not the heart has an abnormal size or is a "tall" heart, and if so, corrective measures are taken. In a preferred embodiment, a shift-variant cosine function is used as a model function fitted to the selected cardiac boundary points.
