Abstract: The disclosure facilitates management of a plurality of related data stores by tracking metadata changes across the data stores, detecting the impact of the tracked metadata changes, and generating alerts based on the detected impact. Metadata change data from a plurality of data stores are received by a change impact engine and recorded to a centralized metadata change data structure. At least one change impact rule is applied to the recorded metadata change data and, upon detection of an impact based on the applied change impact rule, an alert based on the applied impact rule is generated. Consolidating the metadata change data from multiple data stores and detecting metadata changes that will significantly impact the operation of the associated system provide advance opportunities to manage and/or mitigate the impact of the metadata changes.

The upper and/or lower boundary defines a shape having two lobes, each with an outer edge with a convex profile, and a connecting portion extending between the lobes, such that the connecting portion is defined by two outer edges extending between the outer edges of the lobes, wherein at least one of the outer edges of the connecting portion has a concave outer profile.

Abstract: In some examples, a feedthrough assembly for a medical device may include a ferrule. The ferrule defines an aperture extending through the ferrule from an outer end surface defined by the ferrule to an end inner end surface defined by the ferrule. The aperture includes a first portion having a first diameter and a second portion having a second diameter less than the first diameter. The aperture defines a longitudinal axis extending therethrough and the ferrule defines a ledge between the first and second portions of the aperture that extends radially inward toward the longitudinal axis. The feedthrough assembly further may include a conductive pin within the aperture and an insulating member surrounding at least a portion of the pin. The insulating member may electrically insulate the conductive pin from the ferrule, and the ledge and a surface of the insulating member adjacent the ledge may define a space therebetween.

Abstract: A golf club head includes a body and a face plate insert. The body includes an annular face support having a recessed shelf configured to receive the face plate insert, and partially defining a cavity. The face plate insert includes a hitting surface and a rear surface that is opposite the hitting surface. The face plate insert is disposed within the annular face such that the rear surface of the face plate insert abuts the recessed shelf. The face plate insert includes a polymeric material that is disposed across the cavity and can be at least partially exposed through a rear opening of the cavity.

Abstract: A ball striking device, such as a golf club, includes a head that includes a face having a ball striking surface configured for striking a ball and a body connected to the face and extending rearward from the face. A face member formed primarily of a metallic material forms the face, and a body member is connected to the face member and extends rearward from the face member to form at least a portion of the body. The body member is formed at least partially of a polymer material, and has a doped portion containing a doping material dispersed within the polymer material. The doping material may have a different density than the polymer material, such that the doped portion has a different density than the portions of the body member not containing the doping material. A co-molding method may be used to form the ball striking device.

Abstract: A computer-implemented method according to one embodiment includes receiving, by a target system from a source system, a description of a set of data updates that are to be written to the target system. For each given portion of data of the target system that is to be rewritten during performance of the set of data updates, forward lookup is performed on the target system for determining a physical storage address of the given portion of data. The method further includes marking each of the determined physical storage addresses of the portions of data of the target system in a copy of a reverse lookup table of the target system. The marked-up reverse lookup table is used for determining an ordering in which the performance of the set of data updates would result in a least amount of garbage collection being performed while performing the set of data updates.

Abstract: Playlists having media items from more than one source are described. Media items in a first library are mapped to media items from an online media item store. Media items within the playlist that can be found in the first library will be played from the first library, while media items not within the first library will be played from the online media store. By identifying media items present in both libraries and playing them only from the first library, the described method can reduce the royalties needing to be paid by the online media store. Further methods are disclosed for setting limits on the number of media items that can be shared by a second library.
