Abstract: A device images time-wise in parallel using transducer elements of a group. The elements are of a current group and imaging is time-wise sequential by group. The groups may be spatially disposed with respect to each other so as to mutually intermesh element-wise. The imaging may include volumetric imaging. The device may be configured for not collectively using any of the elements to focus, nor to steer, a beam used in the imaging. The device may further be operable to transition between spacing states at least one of which is characterized by a respective minimum, nonzero, degree of intra-group, element-to-element non-adjacency, or may be fixed at a selected spacing state. The transitioning may be automatic, in response to input indicative of blood vessel size and/or depth.

Abstract: An automatic, stand-alone, hand-held ultrasound blood-vessel examination device includes a reduced number of transducer elements and presents a simplified user interface, without the need for displaying an image of any of the vessels. The probe, in one embodiment, acquires and examines a volume of interest, searches for a target vessel, tests the vessel for normality of blood flow, and reports the diagnosis, all automatically and without need for user intervention. In another embodiment, the probe finds a body vessel in a volume, and extracts a clinical Doppler parameter, all automatically and without need for user intervention.

Abstract: A method, system, and algorithm detects graphite responses in optical mark recognition documents using inexpensive visible-light scanners. The invention is invariant to the numerous background colors and artwork in typical optical mark recognition documents. A superposition of a graphite response image and a background image is modeled. The background image in turn is modeled as a superposition of screening, artwork, lines, and machine text components. A sequence of image processing operations and a pattern recognition algorithm is used to isolate the graphite response image from a test document by systematically removing the components of the background image. The image processing operations consist of grayscale and color segmentation and the application of the Hough transform. Components that are not removed by image processing operations are identified by calculating their texture features, and removed using a multivariate Gaussian classifier.

Abstract: A device (308) is configured for examining pulsatile flow, for deriving, based on the examined flow, spectral characteristics and for, based on the derived characteristics, determining which one or more pulse cycles are to be selected as representative of the flow. The cycles selected can be consecutive and amount to a predetermined number of cycles, such as five. The cycles (200) subject to selection may initially be filtered out based on waveform anomalies, with the surviving cycles in a consecutive group of sufficient number being judged based on parameters such as waveform caliper measurements and other types of the characteristics. Good cycles are detected (202) by their lack of variation, with respect to the measured parameters, from each respective, parameter median over the spectrogram cycles not initially filtered. The technique may, according to user selection, take into account additional parameters suited to particular medical application. Uses include correctly identifying an artery by name.

Abstract: Method, system and software product for identifying high risk pregnancies comprising the step of generating a spectrogram from ultrasound Doppler signals reflected from the uterine artery and determining the maximum frequency envelope of said spectrogram, and of defining a systolic part and a diastolic part of the maximum frequency envelope and calculating an area ratio under said systolic and diastolic part (AR). This area ratio relates to the blood volume in the uterine artery.

Abstract: A device is configured for interrogating a blood vessel to derive flow characteristics (S628) and for, responsive to the deriving and based on the derived characteristics, anatomically identifying the vessel. A spatial map of the vessels may be generated based on the interrogating, and specifically the Doppler power computed from data acquired in the interrogating. Subsequent interrogating (S668) may occur, based on the map and on a user-selected set of vessels and/or vessel categories, to derive clinical Doppler indices. The device can be designed to automatically set a sample volume (509) for the subsequent interrogating, and to operate automatically from the user selection to display of the indices. The display may further include an image (524) of the vessels summoned by the set, annotated by their individual anatomical names, and optionally a diagnosis relating to blood flow. The displayed image may be enlarged to zoom in on the user's onscreen selection.

Abstract: A device images time-wise in parallel using transducer elements of a group (428, 432, 436, 440). In some embodiments, the elements are of a current group and imaging is time-wise sequential by group. The groups may be spatially disposed (408, 412) with respect to each other so as to mutually intermesh element-wise. The imaging may include volumetric imaging. The device can be configured for not collectively using any of the elements to focus, nor to steer, a beam used in the imaging. The device might be operable to transition between spacing states (404, 408, 412) at least one of which is characterized by a respective minimum, nonzero, degree of intra-group, element-to-element non-adjacency (470), or may be fixed at one spacing state. The transitioning may be automatic, in response to input indicative of blood vessel size and/or depth.

Abstract: Disclosed is an ultrasound device for measuring blood flow velocity in a blood vessel of a subject without imaging functionality in the device. The measurement depends upon reflections of a collimated beam of ultrasound from a subject's body part. Received electrical signals representative of the reflected ultrasound energy is used for generating a representation of blood flow at a plurality of predetermined locations in the volume and calculating a first blood flow velocity at each of the locations. The representation of flow is used for delineating the blood flow in the blood vessel in the volume. An angle calculating unit calculates the Doppler angle between the direction of the radiated collimated beam in the delineated blood flow at each point. A velocity calculator calculates a second blood flow velocity at the plurality of points based on the calculated first velocities and the calculated angle at the point.

In another embodiment, the probe finds a body vessel (108-112) in a volume, and extracts a clinical Doppler parameter, all automatically and without need for user intervention.

Abstract: Petri net models, of systems, communication protocols, and software programs, which include place objects, transition objects, arcs, and initial markings, may be used for testing and verification. To reduce computations, a new unfolding process is performed on the net models. Two or more candidate buffer place interfaces are selected from the input net model. The input net is subdivided with a preliminary cut to form two subnets, wherein the preliminary cut passes through suitable candidate buffer place interfaces, objects of each of the subnets other than the suitable candidate buffer place interfaces are reachable from at least one initial marking, and the subnets do not include a mix of initial and non-initial marking places. Each of the two subnets are unfolded and then joined to form an unfolded net that is behaviorally equivalent to original input net model. The unfolded net is then stored in a storage unit.

Abstract: In one embodiment, a wireless device communicates an uplink data stream to a wireless network using two radio access technologies (RATs) simultaneously. The wireless device has a host controller unit that segments the uplink data stream and provides each of the segmented portions to either a first baseband module corresponding to a first RAT or a second baseband module corresponding to a second RAT. The first baseband module modulates the data that it receives using the first RAT and provides the modulated data to a first radio frequency (RF) module. The second baseband module modulates the data that it receives using the second RAT and provides the modulated data to a second RF module. The first and second RF modules convert the modulated data to RF and provide the RF signals to first and second antennas, respectively. In alternative embodiments, more than two RATs are used simultaneously for communications.
