Abstract: Shear wave imaging is provided in medical diagnostic ultrasound. A region is imaged to determine a location in which to calculate shear velocity. The shear velocity is estimated for the location. The imaging may guide the identification of the location, reducing the time to determine useful shear information. The estimate of shear may be validated, such as using cross-validation, to indicate the confidence level of the shear value. The shear velocity may be displayed relative to a scale of shear velocities associated with a type of tissue, such as tissue for an organ. The location on a scale may be more intuitive for a user.

Abstract: A hydration system is disclosed for carrying readily dispensable fluids, such as water. A removable cap having an annular valve covers a container. A flexible tube is disposed through the center of the annular valve and extends generally to near the bottom of the container. A bite valve is attached to the end of the tube that is external to the container. When the annular valve is closed, the hydration system is substantially closed, preventing fluid loss. When the annular valve is opened, an air channel is created that allows air to enter the container, facilitating the flow of fluid from the container through the flexible tube. The annular valve may be a poppet-type valve having a valve stem that is movable between the closed position and the open position. The hydration system is sufficiently compact to be utilized with narrow-mouthed bottles.

Abstract: Methods and systems for improving a user's experience with a set-top box. A system for allowing a user to subscribe to a subscription service when the user selects to view the content of the subscription service is provided. A system for replication of configuration information for set-top boxes is provided. A system for monitoring and blocking content being viewed by another is provided. A system that allows nontelevision programming content to be represented as a channel of an electronic program guide is provided.
