Abstract: A seal assembly for a rotary machine is positioned between a rotating component and a stationary component of the rotary machine. The seal assembly includes a seal bearing face that opposes the rotating component and a slide device. The slide device is positioned between different fluid pressure volumes in the rotary machine. The slide device axially moves toward the rotating component responsive to pressurization of the rotary machine. The slide device includes cross-over ports and the seal bearing face includes feed ports. The feed ports extend through the seal bearing face to form an aerostatic portion of a film bearing between the seal bearing face and the rotating component. The seal bearing face and/or the rotating component is a non-planar surface that, during rotating motion of the rotating component, forms an aerodynamic portion of the film bearing between the seal bearing face and the rotating component.

Abstract: The present disclosure generally relates to data storage devices, and more specifically, to a magnetic media drive employing a magnetic recording head. The head includes a main pole at a media facing surface (MFS), a trailing shield at the MFS, and a heavy metal layer disposed between the main pole and the trailing shield at the MFS. Spin-orbit torque (SOT) is generated from the heavy metal layer and transferred to a surface of the main pole as a current passes through the heavy metal layer in a cross-track direction. The SOT executes a torque on the surface magnetization of the main pole, which reduces the magnetic flux shunting from the main pole to the trailing shield. With the reduced magnetic flux shunting from the main pole to the trailing shield, write-ability is improved.

By utilizing three read heads within each data head, data can be read from a tape that has experienced tape dimensional stability, as at least one read head will be near a center of each data track of the tape.

Abstract: Described herein are dialog systems, and techniques for providing such dialog systems, that are suitable for use on standalone computing devices. In some embodiments, a dialog system includes a dialog manager, which takes as input an input logical form, which may be a representation of user input. The dialog manager may include a dialog state tracker, an execution subsystem, a dialog policy subsystem, and a context stack. The dialog state tracker may generate an intermediate logical form from the input logical form combined with a context from the context stack.

Abstract: The concept of a service layer message template is introduced, which may be a request template or a response template. Message templates may be created and stored at the service layer. Each message template may contain a set of request or response parameters and their values. Once in place, an application can send a request to the service layer that does not include the request parameters contained in the message template (i.e. request template); instead, a message template identifier may be sent. Since request parameters are included in the message template and stored at the service layer, communication overhead between the service layer and the application (or another service layer) may be reduced.
