Abstract: A method for training a system for predicting a probability of occurrence of cardiac event is provided. The method includes obtaining sets of electrocardiograms of subjects, each set of electrocardiograms comprising at least one electrocardiogram each obtained, a) prior to and b) during or after an occurrence of a cardiac event, or both. The method includes extracting a first approximation of a time series data. The method also includes obtaining electrocardiograph signals that produced the electrocardiograms. The method also includes creating a training dataset from the extracted time series signals and the electrocardiograph signals for training a first and a second approximation of an electrocardiogram for representing an electrocardiograph signal that produced the electrocardiogram. The method further includes training a second model for extracting a cardiac marker from the second approximation of the electrocardiogram of the subject and calculating a probability of occurrence of a cardiac event.

Abstract: A system to acquire and decode patient clinical information is provided. The system includes an off-the-shelf device. The off-the-shelf device includes at least a processor and memory communicatively coupled to the processor and a low power, long range wireless transmission means communicating with a medical device through one of its ports. The memory includes a plurality of modules for execution by the processor, wherein the modules are configured at least for detecting information about a medical device it is communicatively coupled to; acquiring patient clinical information from the medical device; transforming the patient clinical information into an open standard format; transmitting the transformed patient clinical information securely over a network using a low power, long range wireless protocol. The system also includes a central server configured for receiving the transmitted data for storing and analysis.

Abstract: A continuous, non-invasive fetal heart rate measurement is produced using an ultrasound probe positioned on the abdomen of the mother. The ultrasound probe includes a plurality of ultrasound transducers that are positioned within a housing having a transmission surface. The transmission surface is configured to defocus the individual ultrasound beams created by the plurality of ultrasound transducers. The transmission surface defocuses the ultrasound beam and creates a wider area of coverage for the ultrasound probe. The controller contained within the heart rate monitor selectively activates different combinations of the plurality of ultrasound transducers to reduce the signal-to-noise ratio while allowing the ultrasound probe to locate the fetal heart beat and subsequently increase the signal-to-noise ratio during continuous heart rate monitoring.

Abstract: An ultrasound transducer and method of producing same takes advantage of the properties of two differing materials to optimize the transducer. More specifically, the transducer has one or more emitters made of lead zirconate titanate PZT) crystals that are affixed to a wearable material made of polyvinylildene fluoride (PVDF). As such, the PZT crystals are an effective emitter of ultrasound energy into an object and/or area of interest, such as a patient for maternal and/or fetal care monitoring, while the PVDF material has a low impedance and therefore effectively receives the ultrasound energy returned from the object and/or area of interest. The PVDF material comprises a wearable form factor, whereby the transducer utilizes different properties of different materials and combines them into a common transducer.

Abstract: A technique is provided for accessing data stored in separate databases. A communication system having a first and second computer system is used to retrieve data from a primary or a secondary database. The primary and secondary databases are coupled to the first computer system. A data access controller is used in the system to automatically shift the first computer system from retrieving data from the primary database to retrieving data from the secondary database. The data access controller shifts when a communication error between the primary database and the first computer system is detected by the system.
