Publication number: 20170188892Abstract: A method for distinguishing between individual human subjects using plethysmographic waveforms. In one embodiment, the method comprises the steps of: receiving a plurality of plethysmographic signals from different individuals; normalizing the signals to the same period length and mean; changing the basis of each of the plurality of signals to obtain its basis vectors and coefficients; reducing the number of coefficients for each signal in the plurality of signals; and calculating the covariance matrix and mean for each individual's set of normalized and dimensionally-reduced plethysmograph waveforms. In another embodiment, the method further comprises the step of taking the Mahalanobis distance between each new plethysmograph waveform that has also been normalized and dimensionally reduced and the stored models of all individuals. In yet another embodiment, the method further comprises the step of finding the index of the stored model with the minimum Mahalanobis distance.Type: ApplicationFiled: January 5, 2017Publication date: July 6, 2017Applicant: Ivy Biomedical Systems, Inc.Inventor: Jennifer Laine

Publication number: 20140330149Abstract: Disclosed herein are various embodiments of methods, systems and devices for detecting atrial fibrillation (AF) in a patient. According to one embodiment, a patient places his or her left and right hands around left and right electrodes and a hand-held atrial fibrillation detection device acquires an electrocardiogram (ECG) from the patient over a predetermined period of time such as, by way of example, one minute. After acquiring the ECG from the patient, the device processes and analyzes the ECG and makes a determination of whether the patient has AF. The device may further be configured to provide a visual or audio indication of whether the patient has AF, or does not have AF. The device may be employed in a health care provider's office without the need for complicated or expensive diagnostic equipment, and is capable of providing an on-the-spot and low-cost diagnosis of AF.Type: ApplicationFiled: April 29, 2014Publication date: November 6, 2014Applicants: Applied Biomedical Systems BV, Applied Medical Systems BVInventors: Richard P.

Patent number: 7916299Abstract: The device and the method are used for optical detection of at least one phase transition between at least two media, which are taken into a line and/or dispensed from the line by an intake and/or dispensing device. A light-emitting transmitter emits light across and onto the line at a measurement point provided for this purpose. A receiver receives the emitted light, which is influenced by media in the line, to form reception signals. At least one waveguide, which is arranged up to the measurement point on the probe, is provided between the transmitter and/or the receiver and the measurement point (M). Due to the fact that the waveguide is arranged in parallel to the line at least in the area near the probe and at least one deflection lens is provided in the area of the measurement point to deflect the light emitted and/or the light to be detected, a phase boundary or state can be detected, and the dead volume is reduced.Type: GrantFiled: January 21, 2008Date of Patent: March 29, 2011Assignee: Stratec Biomedical Systems AGInventors: Martin Trump, Oliver Burk
