    摘要： 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.

    摘要： 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.

    摘要： 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.
