Abstract: An ultrasonic diagnostic imaging system for shear wave measurement transmits push pulses in the form of a sheet of energy. The sheet of energy produces a shear wavefront which is a plane wave, which does not suffer from the 1/R radial dissipation of push pulse force as does a conventional push pulse generated along a single push pulse vector. The sheet of energy can be planar, curved, or in some other two or three dimensional shape. A curved sheet of energy can produce a shear wave source which focuses into a thin line, which increases the resolution and sensitivity of the measuring techniques used to detect the shear wave effect.

Abstract: A device and a method for computing a weighted-average-based position of a shear wave in a temporal domain based on a sampling of shear wave displacements along a propagation path of the shear wave. The weighted-average-based position is, for example, by displacement observed at a plurality of times that correspond to sampling, and represents a time of arrival of the shear wave at a location being sampled along the propagation path. Further, times of arrival of the shear wave at respective locations along the propagation path are functionally related to known inter-location distances to derive shear-wave group velocity. The derived shear-wave group velocity serves as an input into algorithms for estimating a shear elasticity of a medium, such as a body tissue, for purposes of a clinical diagnosis and therapy assessment.

Abstract: The weighted-average-based position (244) in the temporal domain is computed based on the sampling of shear wave displacement (226) along the propagation path. The weighting is, for example, by displacement observed at times (230) corresponding to sampling and represents the time of arrival of the shear wave at the shear-wave propagation path location being sampled. In some embodiments, the computed shear-wave times of arrival at respective locations are functionally related to known inter-location distances (250) to derive shear-wave group velocity. The derived velocity can serve as input into known algorithms for estimating shear elasticity of the medium, such as body tissue, for purposes of clinical diagnosis and therapy assessment.

Abstract: A method and apparatus store data for locations. Updates to the data for the locations are received and stored. In one implementation, a quick read location trigger is received image from a sender, wherein one of the locations is identified based upon the received quick read location trigger. In another implementation, one of the locations is identified based upon an identifier received from a computer aided dispatch. The data with the updates is transmitted to the sender of the quick read location trigger or to an emergency service provider while in transit to said one of the locations.

Abstract: In some embodiments, a method and routing system parameterize a routing policy and apply the parameterized-routing policy to a route. Parameters are assigned to at least some policy statements of the policy. The parameterized policy may be called with parameters stored in a parameter table. In some embodiments, common blocks of the policy may be identified and assigned parameter sets. A commonized routing policy may be reused within more than one policy. In some embodiments, a method and routing system may evaluate a configuration file to determine relationships between route attributes. The relationships may be expressed in one or more mathematical functions, and when a route is received from a peer, the attributes of the route may be modified based on the mathematical functions. In some embodiments, a router and method for implementing routing policy and traffic engineering are provided.

Abstract: A routing policy compiler generates a configuration data abstraction layer of a routing policy which maps configuration to an intermediate layer comprising fields, operators and arguments. A policy repository verifies the intermediate layer against a set of verification rules for one or more client protocols including versions thereof. The policy repository may generate compiled policy transmission language for use by one or more client protocols including versions thereof. The policy compiler supports multiple software versions of client protocols with differing capabilities as well as differing client protocols. In some embodiments, an optimization may be performed on a compiled policy so that route updates are processed more efficiently. The policy compiler may permit the addition of new attributes to a routing protocol without having to recompile. Policy statements may be verified for more that one client protocol including more than one version of a client protocol.

Abstract: A system, which may be used to perform simultaneous grinding and intimate mixing of edible fat-based slurries or emulsions, may include a cylindrical drum having a central longitudinal axis and a curved inner surface and mounted on springs, and a motor and tuned mass coupled to the cylindrical drum to vibrate the cylindrical drum about a center of vibration that is offset from the central longitudinal axis of the cylindrical drum. The system includes at least one pair of partition plates disposed at an angle to the longitudinal axis of the cylindrical drum to divide the cylindrical drum into at least two process zones, the partition plates of the at least one pair having matching apertures and moveable relative to each other between alignment and misalignment. The system may be used, for example, in chocolate manufacture.

Abstract: A vibratory media mill may be used to perform simultaneous grinding and intimate mixing of edible fat-based slurries or emulsions. The invention has particular applicability in the field of chocolate manufacture, where the vibratory media mill can eliminate use of traditional five-roll refiners and/or conches. The vibratory media mill is cheaper and simpler to operate and maintain than traditional grinding and mixing equipment.

Abstract: An ultrasound system and method that identify flow regions within a volume. The system comprises: a survey system for collecting motion data from a target image; a segmentation system for mapping a region of flow within the image based on the motion data; and a flow acquisition system that automatically limits the collection of flow image data within the image to the region of flow.

Abstract: Ultrasonic diagnostic imaging devices are powered by fuel cells providing the continuous production of electrical energy by the direct electrochemical conversion of a hydrogen-based fuel into a flow of current. The ultrasound devices described comprise wireless transducer probes, handheld ultrasound systems, and cart-borne or tabletop ultrasound systems. The fuel for the fuel cells is contained in replaceable containers such as cartridges or ampules. When the fuel is exhausted, the fuel cells are immediately returned to a fully operating condition by replacing the expended unit with a full cartridge or ampule.

Abstract: A body protector assembly for a vehicle for preventing dents and keeping one's vehicle clean. The body protector assembly for a vehicle includes a plurality of thin pieces of material made essentially of plastic and adapted to removably attached to selected parts of a body of a vehicle with powerful magnetic fastening members. A plurality of elongate impact-resistant members are securely mounted to the thin pieces of material with loop members. A sufficiently thin, durable sheet of material is detachably mounted to an underside of a vehicle with fasteners. The sufficiently thin pieces of material can be detachably attached to the thin, durable sheet of material.
