  • Publication number: 20170119259
    Abstract: A method for dual-contrast unenhanced magnetic resonance angiography includes iteratively acquiring flow-dependent slices and flow-independent slices in a region. Each iteration of the acquisition process comprises identifying a flow-dependent slice location within the region and identifying a flow-independent slice location upstream from the flow-dependent slice location according to blood flow in the region. Each iteration further includes applying a first radio frequency (RF) saturation pulse to the region such that MR signals from veins in the region are substantially suppressed, and applying a second RF saturation pulse to the flow-dependent slice location such that MR signals from background muscle and arterial blood in the region are substantially suppressed. A flow independent slice is acquired at the flow-independent slice location after the second RF saturation pulse is applied and before unsaturated arterial blood has maximally flowed into the region.

The method modifies the general population PWV-BP transform using the at least a first PWV and BP measurement, and updates the general population PWV-BP transform. If a Sufficient number of simultaneous PWV and BP measurements are taken, and determined to be statistically valid, a personal PWV-BP transform can be established.

    Abstract: A system and method are provided for prompting blood pressure-related calibrations. The method relies on statistical hypothesis tests over a current measurement and an accumulated set of calibration points to determine whether the benefit of calibration, in terms of calibration diversity, outweighs the cost to the patient. The algorithm uses statistical methods to predict calibration effect without actually performing the calibration, hence, reducing the calibration ‘cost’ to the patient and increasing the diversity of calibration points and thereby improving PWV-BP transform quality. The method is applicable to both manual and automatic calibration modes.

    Abstract: A system and method are provided for using demographic data to derive a PWV-BP transform. The method provides a PWV measurement device with a non-transitory memory, processor, and a calibration application for supplying pseudo-calibrated PWV values. The method loads into the memory a first database of information cross-referencing age compared to central-aortic PWV-BP transforms, a second database of information cross-referencing age and gender compared to systolic and diastolic blood pressure, and a third database of information cross-referencing age as compared to whole-arm PWV. Whole-arm PWV measures a distance between a superasternal notch and index finger, divided by a transit time of an arterial pulse from to heart to the index finger tip. After accepting age and gender data from a first user, the calibration application interpolates the information from the first, second, and third databases, and derives a pseudo-calibrated whole-arm PWV-BP transform for the first user.

    Abstract: An ADL monitoring system uses a set of sensors each adapted to respond to an activity and to generate a sensor output signal representative of the detected activity level or type. An activity density map is formed. The activity level or type is compared with a range of activity levels or types represented in a map which characterized a reference spread of activity levels over the same time period as the activity density map. A probability analysis is then used to identify initial anomaly points. For these the initial anomaly points, a test of activity permutations is carried out to find timeslots in the activity density map which may be reordered to remove the initial anomaly points. In this way, anomalies at the level of individual timeslots can be identified, and the permutation approach makes the system robust to changes in the order in which activities are carried out by a subject.

  • Publication number: 20170119290
    Abstract: The present invention relates to systems and methods using optical or electrical spectroscopy for accurate detection and monitoring of biological tissue properties in a noninvasive manner. To perform in vivo diagnose with more accurate and repeatable measurements, an air-tight micro suction cup is placed against biological tissue under test (such as skin of a patient), around which an electrical or optical sensing system comprising excitation and detection sensors is integrated. Applying a high power suction pump over the micro cup, a negative pressure is generated to reshape the skin covered by the cup to a contour suitable for better measurement results. Most important, as the suction power increases, certain amount of blood flow or body fluid is brought to skin layer, providing great potential of improving those diagnoses that require direct analysis over these biological components.

  • Publication number: 20170119294
    Abstract: A “one-step”, single-handed device for obtaining small, precise volumes of fluid from animals is able to quickly and easily draw a fluid sample. The device comprises an extraction component and a collection component that are coupled together and disposed along a grip handle. The user manipulates the device so as to initiate the extraction of the fluid, and then collect the fluid in a component that can quickly and easily be removed from the grip handle—allowing the handle to be re-loaded and used again and again. The extraction component may comprise a hypodermic needle and the collection component may comprise a pre-calibrated pipette, where the pipette is positioned directly behind the needle and will thus draw the extracted fluid into a pre-sized chamber within the pipette.

  • Publication number: 20170119295
    Abstract: The ability to detect when a person is hiding important information has high value in many applications. A new class of systems, termed autonomous scientifically controlled screening systems (ASCSS), is designed to detect individuals' purposely hidden information about target topics of interest. ASCSS represents a systematic synthesis of structured interviewing, orienting theory, defensive response theory, non-invasive psychophysiological measurement, and behavioral measurement. To evaluate and enhance the design principles, an automated screening kiosk (ASK) system was constructed. The ASK system has been used in a physical security screening scenario in which participants constructed and attempted to smuggle a fake improvised explosive device (IED). The ASK system results indicate that ASCSS enables more widespread application of credibility assessment screening systems.

  • Publication number: 20170119296
    Abstract: Systems and methods for detecting deceptive intent of a subject include observing eye movements of the subject and correlating the observed movements to known baseline neurophysiological indicators of deception. A detection system may record eye movement data from the subject, compare the eye movement data to a data model comprising threshold eye movement data samples, and from the comparison make a determination whether or not the subject is lying. The detection system may create an alert if deception is detected. The eye movements detected include saccadic and intersaccadic parameters such as intersaccadic drift velocity. Measurements may be collected in situ with a field testing device, such as a non-invasive, non-contact device attached to the subject's computing device and configured to non-obtrusively record the eye movement data.

  • Publication number: 20170119297
    Abstract: A computer-implemented method of assessing a mental state of a subject (106) includes receiving (302), as input, a heartbeat record (200) of the subject. The heartbeat record comprises a sequence of heartbeat data samples obtained over a time span which includes a pre-sleep period (208), a sleep period (209) having a sleep onset time (224) and a sleep conclusion time (226), and a post-sleep period (210). At least the sleep onset time and the sleep conclusion time are identified (304) within the heartbeat record. A knowledge base (124) is then accessed (306), which comprises data obtained via expert evaluation of a training set of subjects and which embodies a computational model of a relationship between mental state and heart rate characteristics. Using information in the knowledge base, the computational model is applied (308) to compute at least one metric associated with the mental state of the subject, and to generate an indication of mental state based upon the metric.
