Abstract: A method for detecting stick-slip in a drillstring includes (a) measuring a parameter that is a function of a torque applied to the drillstring by a top drive system over a selected time period, the measuring being performed by at least one surface sensor that produces measurement data including torque values over a frequency range; (b) filtering out measurement data that has a frequency outside a selected frequency band, the selected frequency band including a resonant frequency of the drillstring; (c) identifying a minimum and a maximum torque value in the filtered measurement data and determining a difference of these two values; (d) determining a surface stick-slip index by dividing the difference of the maximum and minimum torque values by an average torque value over the selected time period; and (e) displaying the surface stick-slip index on a display.

Abstract: The invention is directed to a first electronic device. The first electronic device receives a phone call that was routed to the first electronic device by a call-routing service. While receiving the call, the first electronic device receives a request to route the phone call to a second electronic device. In response to receiving the request to route the phone call to the second electronic device, in accordance with a determination that a first routing criteria have been met, the first electronic device sends a request to the call-routing service to route the phone call to the second electronic device instead of routing the phone call to the first electronic device. In accordance with a determination that a second routing criteria have been met, the first electronic device causes call data associated with the call to be routed through the first electronic device to the second electronic device.

Abstract: The embodiments of the Socket and Ratchet Holder are comprised of a socket body and a strap assembly. The strap assembly is comprised of a longitudinal strap and a cross strap. The socket body is comprised of a plurality of socket apertures. The plurality of socket apertures are comprised of a range of sizes of apertures ranging from a small aperture to a large aperture to accommodate the range of sizes of sockets in a typical socket wrench set. The socket body is comprised of narrow-end loop aperture and a wide-end loop aperture. The socket body is comprised of a wrench aperture so that when the socket wrench is to be stowed, the user secures the socket wrench from the bottom of the socket body into the wrench aperture. The socket body is also comprised of a universal aperture to stow the universal socket joint and the socket extension.

The system and method may also include using the yard planner system to form an initial yard plan based on the yard data, monitoring the yard data over time with the yard planner system, and updating the initial yard plan to form an updated yard plan based on changing yard data over time.

Abstract: Methods, apparatuses, and systems for managing digital content in hierarchies are described. A first version of a digital image is received from an external device which tracks changes to the first version. It is determined that a second version of the digital image, changes to which have been tracked, exists. Based on comparing the tracked changes of both versions, the versions are combined. The first version is created by splitting the second version, which is stored in a master hierarchy, and transmitting the split version to the external device. During splitting, a child hierarchy of information is split from the master hierarchy, the child hierarchy including portions of the master hierarchy to access the second version such that the second version can be accessed independent of the master hierarchy. Changes to the versions are tracked in change tables, for example, using values that are mashed into a single record.

Abstract: Methods, systems, and apparatus, including computer program products, for synchronizing database changes among multiple devices. In one aspect, a method includes determining one or more primary differences between a primary database and a local synchronization database; receiving, from a secondary device, one or more secondary differences associated with a secondary database; merging the primary differences and the secondary differences to generate a set of merged differences; providing the set of merged differences to the secondary device; receiving, from the secondary device, an acknowledgment indicating receipt of the set of merged differences; and updating the primary database in accordance with the set of merged differences after receipt of the acknowledgment. Further, at least one conflict can be detected between the primary differences and the secondary differences, and can be resolved prior to generating the set of merged differences.

Abstract: Provided herein is an endothelial scaffold comprising, consisting of, or consisting essentially of decellularized corneal stroma. In some embodiments, the scaffold has cultured endothelial cells seeded thereon. Methods of treating a patient in need of corneal endothelial transplant are also provided, including implanting the scaffold as described herein onto a cornea of the patient (e.g., by deep keratectomy).
