  • Patent number: 11134858
    Abstract: A method of locating a source of vibrational cardiac energy within a human, includes acquiring time synchronized vibrational cardiac data noninvasively from a surface of the human's body with at least three transducer channels. A time-to-frequency transformation is performed on the vibrational cardiac data to obtain a sequence of heart cycle ensemble averaged power spectral density (PSD) estimates. A feature is identified in the PSD estimates. A vernier band (VB) in frequency is established for the feature. The VB portion of the PSI) estimates that correspond to the feature are processed to obtain a vibrational energy intensity level estimate at a spatial location within the human's body. A metric of clinical significance is obtained from the strength of the estimated vibration intensity within a VB and at a location relative to a background noise level.

  • Patent number: 10510022
    Abstract: Systems and methods for machine learning, models, and related explainability and interpretability are provided. A computing device determines a contribution of a feature to a predicted value. A feature computation dataset is defined based on a selected next selection vector. A prediction value is computed for each observation vector included in the feature computation dataset using a trained predictive model. An expected value is computed for the selected next selection vector based on the prediction values. The feature computation dataset is at least a partial copy of a training dataset with each variable value replaced in each observation vector included in the feature computation dataset based on the selected next selection vector. Each replaced variable value is replaced with a value included in a predefined query for a respective variable. A Shapley estimate value is computed for each variable.

  • Publication number: 20190209067
    Abstract: Embodiments of the invention provide bladder fullness monitoring systems and associated methods for such monitoring. One includes a controller and an active optical sensor that is affixed to a patient's bladder. The sensor emits light onto the bladder and further detects light reflected from the bladder, in order to generate an output signal that indicates an amount of emitted light was reflected back to the detector. The controller is coupled to the optical sensor to receive and interpret the output signals, e.g., to determine when the bladder is full. The controller may be operatively coupled to a urinary control apparatus which uses the output signals to trigger urination in patients who have lost the ability to voluntarily urinate. Embodiments are particularly useful for monitoring bladder fullness in patients who have lost bladder sensation and/or the ability to voluntary urinate and rely on a urinary control apparatus in order to urinate.

  • Patent number: 9591972
    Abstract: Method and apparatuses are described to evaluate a state of health of a coronary artery. Vibrational cardiac data from a transducer is received from a first location. The transducer measures vibration of a surface of a human's body non-invasively. The vibrational cardiac data is processed in a second location to create processed vibrational cardiac data. The processing includes separating an unwanted coronary event from the vibrational cardiac data. The processing further includes performing a time-to-frequency transformation on the vibrational cardiac data from a portion of a diastolic interval within a heart cycle to obtain a vibrational frequency power spectrum estimate. The processing includes evaluating a state of health of the coronary artery using the processed vibrational cardiac data.

  • Patent number: 8961427
    Abstract: Methods and apparatuses are described to obtain cardiac data, which includes acquiring vibrational field cardiac data from a transducer wherein the transducer measures vibration over a surface of a human's body. An unwanted coronary event is separated from vibrational cardiac data. A transient event is extracted from the vibrational cardiac heart cycle data. The transient event occurs during a diastolic interval within a heart cycle. The transient event is evaluated for a condition of coronary artery blood flow turbulence and a condition of health of a coronary artery is assessed from a feature in the vibrational frequency power spectrum estimate.

  • Patent number: 8419651
    Abstract: A method includes acquiring vibrational cardiac data from an array of N transducers wherein the transducers are coupled to a human. A master replica is selected from a segment of the vibrational cardiac data. The master replica is correlated with the segment to obtain a plurality of local maxima. Vibrational cardiac data that were emitted during a diastolic interval are extracted from each heart cycle with the aid of the plurality of local maxima. A two-dimensional space-time frequency power spectrum is processed for Equivalent Rectangular Bandwidth, which provides estimates of the energy produced by turbulent blood flow through a coronary stenosis.

  • Patent number: 7840473
    Abstract: A system and method of selling reinsurance includes identifying a reinsurance product and a capacity of the reinsurance product to be sold and calculating a fair risk price for the reinsurance product. The reinsurance product is then offered to potential buyers via an electronic auction, wherein a minimum bid in the electronic auction is determined, at least in part, by the fair risk price. Bids are received from the buyers for portions of the capacity of the reinsurance product and are ranked in accordance with a calculated profitability value and/or time of receipt. Buyers are notified of a status of their respective bids, and particularly, whether bids have been tentatively accepted, partially accepted, or excluded, i.e., rejected. Upon notification of bid status, buyers are given the opportunity to modify bid parameters in an attempt to have their bids ranked at higher a level, thereby increasing the chance of the bid being accepted.

  • Patent number: 6151022
    Abstract: Displayed inconsistencies and errors within a visual resource (e.g., dialog, menu) and between two visual resources are automatically detected without requiring the execution of an application having either of the visual resources. When a source application is localized, its visual resources are extracted and translated into the target language. This translation of the visual resources often causes errors in the visual display. The visual resource analyzer of the invention identifies these errors without requiring execution of either the source or localized versions of the application, which enables the errors to be easily corrected. Furthermore, the elements of a visual resource are analyzed for display anomalies, such as alignment errors and overlapping other elements.

  • Patent number: 4180069
    Abstract: A plunger rod and piston for a syringe which are easily and quickly assembled with a minimum force. The plunger rod has a tip of truncated "christmas tree" shape and the piston, which is of a flexible resilient material, has a pocket of complementary shape to receive the plunger tip. The tip includes a series of frusto conical segments of decreasing cross-wise dimension from the base to the terminal end of the tip thereby defining a plurality of circumferentially extending, axially spaced radially directed shoulders.The piston pocket has a series of frusto conical pocket sections decreasing in size from the open end thereof to define a plurality of circumferentially extending axially spaced, radially directed, flexible lips. Upon assembly of the tip in the piston pocket, the lips deflect to permit seating of the tip therein and then engage behind the radial shoulders to lock the parts together.
