Abstract: Apparatus, for use at a valve of a heart of a subject, includes a first catheter, a second catheter, and a translation element. The translation element is connected to, and operatively joins, the distal ends of the first catheter and the second catheter. The translation element is operable to translate the distal ends laterally with respect to each other to transition the apparatus between (i) a first state in which the distal ends are held next to each other for transluminal advancement to the heart, and (ii) a second state in which the distal ends are spaced apart from each other for positioning at a first location on the annulus and a second location on the annulus, respectively. The apparatus is configured to, while in the second state, from the distal ends, anchor a first tissue anchor at the first location, and a second tissue anchor at the second location.

Abstract: An ophthalmic device includes an optic including an optic axis and a closed-loop haptic structure coupled to the optic via a frame surrounding the optic, the closed-loop haptic structure including a closed loop extending from first and second attachment points to the frame. The closed loop includes a first hinge and a second hinge. The first hinge has a first section having a first component extending in a first angular direction, a second section having a second component extending in a second angular direction opposite to the first angular direction, and a first connecting section between the first section and the second section. The second hinge has a third section having a third component extending in the second angular direction, a fourth section having a fourth component extending in the first angular direction, the fourth section being connected to the second section to form the closed loop.

Abstract: A computer implemented method includes detecting user interaction with mixed reality displayed content in a mixed reality system. User focus is determined as a function of the user interaction based on the user interaction using a spatial intent model. A length of time for extending voice engagement with the mixed reality system is modified based on the determined user focus. Detecting user interaction with the displayed content may include tracking eye movements to determine objects in the displayed content at which the user is looking and determining a context of a user dialog during the voice engagement.

Abstract: Provided is a crude oil additive comprising a pyrolysis oil fraction. In some embodiments, the crude oil additive further comprises a dispersant. Also provided are methods of preparing the crude oil additive as well as methods for reducing the viscosity of crude oil and methods for increasing the API gravity of crude oil.

Abstract: An electronic device displays a content region including first content that contains an image; and, while displaying the first content, detects an input at a location that corresponds to the location of the image. In response, the electronic device, in accordance with a determination that the input includes an intensity above a respective threshold and that the image is associated with a link to second content that is different from the first content, displays a preview of the second content while maintaining display of at least a portion of the first content in the content region; and, in accordance with a determination that the input includes an intensity above the respective threshold and that the image is not associated with a link to additional content, displays an enlarged version of the image while maintaining display of at least a portion of the first content in the content region.

Abstract: Systems, methods, and computer readable media to improve the operation of graphics systems are described. In general, techniques are disclosed for determining the computational need of GPU-centric elements executing from within pages of another application, selecting one or more GPU's appropriate to the need, and transitioning the system to the selected GPUs.

Abstract: An electronic device, while displaying a user interface that corresponds to at least a portion of a web page on a display, detects a touch input on a touch-sensitive surface at a first location that corresponds to the displayed portion of the web page on the display. While detecting the touch input on the touch-sensitive surface, the electronic device detects an intensity of the touch input on the touch-sensitive surface, determines whether the intensity of the touch input on the touch-sensitive surface has changed from below a first intensity threshold to above the first intensity threshold, and in response to determining that the intensity of the touch input on the touch-sensitive surface has changed from below the first intensity threshold to above the first intensity threshold, generates a force down event that is distinct from a mouse down event.

Abstract: In some implementations, a website can be certified by a push notification service operator to send push notifications to user devices. A web browser on the user's device can communicate with the website to advertise the user device's ability to receive push notifications. The website can provide to the web browser a certificate indicating that the website is authorized to utilize the push notification service. If the certificate is valid and has not been revoked, the browser can prompt the user to allow push notifications from the website. If the user authorizes push notifications, a device token can be provided to the website that allows the website to send push notifications to the user device through the push notification service. In some implementations, the web browser can be configured to provide websites access to APIs for accessing information stored on a user device.

Abstract: Presenting snap-shots of plug-in content in user interfaces. Input to present a user interface that includes content obtained by executing a plug-in is received. In response, the plug-in is executed to obtain the content. An image representative of the content is identified. Then, the execution of the plug-in is terminated, and the image representative of the content is displayed in the user interface. In the user interface, an object selectable to present the content obtained by executing the plug-in is displayed. When a selection of the object is received, the execution of the plug-in is re-instantiated to obtain the content, and the content is displayed in the user interface in place of the image.
