|20130225938||Connector Interface System for Data Acquisition - A data acquisition system includes a receptacle and a data acquisition device. The receptacle has a housing, sensor inputs to receive data signals from sensors coupled to an object, and a rib to block insertion of a standard Universal Serial Bus (USB) plug and facilitate insertion of a modified USB plug having a slot that mates with the rib. The data acquisition device includes circuitry to receive, store and process data, a USB plug having pins operatively coupled to the circuitry, a first subset of pins configured to receive data signals from the receptacle and a second subset of pins configured to support standard USB communication with USB-compliant devices, and a slot formed in the USB plug such that the slot facilitates interconnection of the USB plug both with standard USB-compliant devices and with the receptacle, the slot mating with the rib to facilitate interconnection.||08-29-2013|
|20130116585||Ventricular Fibrillation Detection - Systems and techniques are disclosed for determining the onset and offset of a ventricular fibrillation event and for distinguishing ventricular fibrillation from noise. In some examples, an electrocardiogram (ECG) signal is obtained; a transform is applied to the ECG signal to obtain an analytical pair, the analytical pair including the ECG signal and the transformed ECG signal; a speed-amplitude is determined from the analytical pair; and an onset of a ventricular fibrillation event is identified based at least one of a value of a cost function of the speed-amplitude over a window and a quantity of occurrences the speed-amplitude crosses a threshold over the window.||05-09-2013|
|20110166468||SYSTEM AND METHOD FOR PROCESSING AND PRESENTING ARRHYTHMIA INFORMATION TO FACILITATE HEART ARRHYTHMIA IDENTIFICATION AND TREATMENT - A system and method for presenting information relating to heart data can involve operations including identifying arrhythmia events in physiological data obtained for a living being, receiving human assessments of at least a portion of the arrhythmia events, determining a measure of correlation between the human assessments and the identified events, and selectively presenting information regarding the identified events based on the measure of correlation. The operations can also include identifying atrial fibrillation events in physiological data obtained for a living being, obtaining heart rate data for the living being, and presenting information regarding the heart rate data and duration of the atrial fibrillation events together with a common time scale to pictographically represent heart rate trend with atrial fibrillation burden during a defined time period.||07-07-2011|
|20100204586||Detecting Sleep Disorders Using Heart Activity - Systems, methods, apparatus, and computer program products for detecting the existence of a sleep disorder in an individual using heart activity. In one aspect, machine-implemented methods include the actions of analyzing a machine-readable heart rate series of a monitored individual in the time domain using one or more digital data processing devices, detecting a cyclic variation in heart rate in the heart rate series as a result of the analysis in the time domain, and outputting, over an output, a report characterizing a sleep disorder event based on the detection of the cyclic variation in heart rate in the heart rate series. The cyclic variation in heart rate is indicative of a sleep disorder.||08-12-2010|
