  • Publication number: 20240130878
    Abstract: A proximal stent-graft retention system includes a stent-graft having a suture loop attached to a proximal end of the stent-graft and a delivery catheter having a distal tip that includes a retention feature. The retention feature can include a slot extending through a sidewall of the distal tip and a trigger wire. The slot of the distal tip exposes a portion of the trigger wire within the tip lumen such that the trigger wire may extend through the suture loop of the stent-graft at the slot of the distal tip of the delivery catheter and is configured to retain the proximal end of the stent-graft in the radially expanded configuration via the suture loop to prevent distal migration and compression of the stent-graft. Proximal retraction of the trigger wire releases the suture loop of the stent-graft such that the stent-graft is no longer coupled to the delivery catheter.

  • Patent number: 11635015
    Abstract: A fluid actuated normally closed coolant control valve. The valve comprises a valve housing, an inlet port, the inlet port configured for fluid communication with either a coolant source or a heat exchanger of a DEF tank; an outlet port configured for fluid communication with the other of the heat exchanger of a DEF tank or the coolant source; a valve chamber, a valve and an actuator configured to actuate the valve. The actuator is a fluid actuated piston. The valve is biased to a closed condition in which the flow of coolant from the inlet port to the outlet port is prevented by the valve. The valve is actuatable to an open condition in which the flow of coolant from the inlet port to the outlet port is permitted, and the valve is withdrawn from the valve chamber, wherein the flow factor for the valve is greater than 1.5.

  • Patent number: 10015391
    Abstract: Operating a camera system that includes a forward-facing camera directed at a forward scene and a rearward-facing camera directed at a rearward scene opposite the forward scene includes analyzing a video stream containing a reflection of the forward scene in a cornea of an eye of a user of the camera system, the video stream captured with the rearward-facing camera. The analyzing includes identifying an item in the reflection moving relative to a field of view of the forward-facing camera and predicted to enter the field of view of the forward-facing camera and identifying a characteristic of the item. A camera setting of the forward-facing camera is adjusted according to the characteristic of the identified item, the adjusted camera setting selected to improve capturing a photograph or video containing the item with the forward-facing camera.

  • Patent number: 9959031
    Abstract: An electronic device includes a display and a touch input disposed over the display. The touch input receives touch inputs from a user and detects location of the user's hand relative to the display including location of the user's hand in front of and not touching the touch input. A controller controls the display of content, including determining an obstructed area of the display that is obstructed from viewing by the user's hand as indicated by the detection made by the touch input; determining that a default location for the display of a new graphical user interface (GUI) element that should be added to the display overlaps with the obstructed area by at least a predetermined amount; and changing a manner in which the new GUI element is displayed so that the new GUI element is not obstructed by the user's hand.

  • Publication number: 20160182435
    Abstract: A user device, such as a smart phone or an augmented reality glasses, receives data to be displayed to a first user, and the user device determines whether the first user is engaged in a social interaction with a second user. The user device presents the data for display to the first user when the first user and the second user are not engaged in the social interaction. For example, the user device may determine whether the second user is turned toward the first user for a threshold amount of time. When the first user is engaged in the social interaction with the second user, the user device withholds the data, determines a break in the social interaction, and presents the data to the first user during the break. The user device may modify the displayed data based on the duration of the break.
