Abstract: A medical device retrieval system can include an elongate core member and an expandable member coupled to a distal portion of the elongate core member. The expandable member can move between collapsed and expanded states. The expandable member has an exterior having barbs positioned therealong. The expandable member can be expanded to contact and engage a portion of a medical device positioned within the vasculature of a patient in order to retrieve and remove the medical device therefrom. When the expandable member moves to the collapsed state, it can move the medical device from a higher profile configuration to a lower profile configuration to facilitate retrieval.

Abstract: In some examples, a catheter may include a catheter body configured such that at least one of a proximal portion or a medial portion of the catheter body has a cross-sectional shape including at least three apexes, adjacent apexes being connected by curvilinear sidewalls, the cross-section being taken substantially orthogonal to a longitudinal axis of the catheter body. In some examples, the entire catheter body has the cross-sectional shape including at least three apexes, adjacent apexes being connected by curvilinear sidewalls. In other examples, only a portion of the catheter body has the cross-sectional shape.

Abstract: In some examples, a catheter includes an elongated body extending between a proximal end and a distal end, and defining an inner lumen, an outer body wall having a wall cross-sectional diameter, and a distal aperture at the distal end. A distal portion of the elongated body including a taper section that tapers from the outer body wall of the distal portion to the distal aperture, with the distal portion defining a plurality of slits open to the distal aperture. The distal aperture has an aperture diameter greater than zero and less than the wall cross-sectional diameter. The distal portion defining the plurality of slits is configured to substantially center the distal end around a guide member when the guide member is introduced in the inner lumen and extends through the distal aperture.

Abstract: One example device includes a camera; a display device; a memory; and a processor in communication with the memory to receive audio signals from two or more microphones or a far-end device; receive first location information and second location information, the first location information for a visual identification of an audio source of the received audio signals and the second location information identifying a direction of arrival from the audio source; receive a first adjustment to a first portion of a UI to change either a visual identification or a coordinate direction of a direction focus; in response to the first adjustment, automatically perform a second adjustment to a second portion of the UI to change the other of the visual identification or the coordinate direction of the direction focus; and process the audio signals to filter sounds outside the direction focus, or emphasize sounds within the direction focus.

Abstract: Systems, apparatus and methods for determining a gesture are presented. According to some aspects, disclosed are systems, apparatus and methods for determining a gesture that compares different images and deduces a direction and/or distance based on a relative size change of a palm in the different images. After a reference palm size is registered, subsequent palm sizes are compared to the reference to determine if and/or how much the hand is moving. The hand gesture is determined based on these relative changes in hand movement.

Abstract: Methods and systems according to one or more embodiments are provided for combining touch inputs and offset non-touch gestures. In an embodiment, a method includes concurrently capturing touch input data on a screen of a user device and non-touch gesture input data, the non-touch gesture input data being indicative of a gesture performed in an area offset from the screen of the user device to inhibit obstruction of a user's view of the screen. The method also includes determining an input command based at least in part on a combination of the concurrently captured touch input data and the non-touch gesture input data. In addition, the method further includes affecting an operation of the user device based on the determined input command.

Abstract: Systems, devices, and methods are described for recognizing and focusing on at least one source of an audio communication as part of a communication including a video image and an audio communication derived from two or more microphones when a relative position between the microphones is known. In certain embodiments, linked audio and video focus areas providing location information for one or more sound sources may each be associated with different user inputs, and an input to adjust a focus in either the audio or video domain may automatically adjust the focus in the another domain.

Abstract: Disclosed is a method and apparatus for run-time adaptive non-uniform mapping of user interface events. In one embodiment, the operations implemented may include: categorizing a display area into a plurality of regions of either a first type or a second type; assigning a gravity value to each of the one or more regions of the second type; determining whether a cursor is within a first region of the first type and is being moved toward a second region of the second type that adjoins the first region; and in response to determining that the cursor is within the first region of the first type and is being moved toward the second region of the second type, the second region having a first gravity value, applying an acceleration factor based at least in part on the first gravity value to a cursor movement.

Abstract: Aspects of the disclosed subject matter are related to a method for utilizing touch object orientation with a touch user interface. First, a first location within a text body on the touch interface is determined. Next, a change in an orientation of a touch object is determined while the touch object remains in contact with the touch device. Thereafter, a second location within the text body on the touch user interface different from the first location is determined based at least in part on the first location and the change in the orientation of the touch object.

A method to reduce or stop the dissolution of metal from a metallic surface in contact with a corrosive composition, and a method to stabilize or recover a corrosive composition containing metal contaminants by adding an effective amount of a corrosion inhibitor to the corrosive composition.

Abstract: Multiple media devices are synchronized in a multi-media system having a computer system, a plurality of media devices, and a display system. Each media device to be synchronized receives a front-end synchronization signal that periodically increments a front-end counter. The front-end counter represents an unadjusted system time (UST). The media device obtains a frame of data to be displayed from a computer system. The media device also receives a back-end synchronization signal that periodically increments a back-end counter each time a frame of data is to be displayed. The back-end counter represents a media stream count (MSC). UST and MSC data are periodically transmitted to the computer system for analysis and use by a synchronization algorithm. Specifically, UST is transmitted to the computer system each time a frame of data is obtained, and a UST/MSC pair is transmitted to the computer system each time a frame of data is displayed.

Abstract: A system and method for compressing an image into bit streams allows data to be presented in either lossy or lossless quality. A lossy quality presentation results in some measurable degradation of an image's visual quality upon expansion. A lossless quality presentation displays the image in its original form. The method divides the image to be compressed into a plurality of regions. For each region, a plurality of adjacent pixels are selected and organized into a set. The corresponding sets for each respective region are identified as a group. The pixel sets within each group are encoded and arranged into two bit streams associated with each respective group. Next, each group's respective bit streams are written into a primary bit stream of constant size and possible a supplemental bit stream of variable length for presenting the image in either lossy or lossless quality.
