Abstract: A mud motor includes a rotor and a stator. Drilling fluid received by cavities of the mud motor drives the rotor to rotate within the stator. The rotor includes one or more rotor lobes extending helically and defining a rotor pitch. The stator includes two or more stator lobes extending helically and defining a stator pitch. The rotor and the stator together define a tapered profile of the mud motor that varies proceeding from a top end of the mud motor to a bottom end of the mud motor. At least one of the rotor pitch or the stator pitch vary as proceeding from the top end of the mud motor to the bottom end of the mud motor.

Abstract: A fireplace system can comprise a firebox and a heat exchanger. The heat exchanger may be in fluid communication with ambient air and may comprise an inlet configured to draw air into the front of the heat exchanger. Operation of a fireplace system comprising a heat exchanger may produce airflow through the heat exchanger by natural convection. The airflow through the heat exchanger may reduce heat transmission from the firebox and the fireplace system.

Abstract: Systems, methods, and software are disclosed herein for indicating a change to content in a document to a user. A document is displayed in a user interface to an application. Content then is introduced into the document from a source external to the document. After the content has been introduced into the document, the source of the content is queried for any changes to the content at the source. If a change has occurred, an indication of the change to the content at the source is introduced in the document.

Abstract: A fireplace system can comprise a first safety barrier and a second safety barrier disposed across a firebox opening and defining an interbarrier space. A fireplace system can also comprise a heat exchanger in fluid communication with the interbarrier space. The interbarrier space and heat exchanger may further be in fluid communication with ambient air. Operation of the fireplace system may produce natural convection through the interbarrier space, resulting in cooling of the safety barrier and the fireplace system.

Abstract: A virtual library of content is provided that makes it appear that the content is all of a supported file type for a particular client accessing the virtual library. When the virtual library is displayed at a client device, the content appears as if it is available in the appropriate format for the client device irrespective of the content's actual format. Content selected from a content library interface for the virtual library is provided in the appropriate format for the client device through the automatic invoking of a content access service. The content access service can determine the appropriate consumption format for the client device and convert to a supported file format any content that is in a non-supported format before providing the content to the client device.

Abstract: Switched-filter duplexing architecture for front-end systems. In some embodiments, a wireless architecture can include a first system having a first signal routing circuit for a first transceiver, and a first antenna node, and be configured to be capable of simultaneous transmit and receive operations for a first band and a receive operation for a second band through the first antenna node. The wireless architecture can further include a second system having a second signal routing circuit for a second transceiver and a second antenna node, and be configured to be capable of a transmit operation for the second band through the second antenna node. The wireless architecture can further include a switchable path implemented to selectively allow the transmit operation for the second band to be performed through the second antenna node of the second system or the first antenna node of the first system.

Abstract: Multiplexing architectures for wireless applications are discussed herein. In some embodiments, a front-end architecture can include a first power amplifier having an output coupled to a transmit filter through a path that is substantially free of a switch. The transmit filter can be configured to support a first transmit band or a second transmit band. The front-end architecture can further include a receive filter configured to support at least a first receive band associated with the first transmit band, and a second power amplifier having an output configured to couple to a first duplexer or a second duplexer through a selector switch. The first duplexer can include a receive portion configured to support a second receive band associated with the second transmit band.

The first duplexer can include a receive portion configured for a second receive band corresponding to the second transmit band.

Abstract: Content curation can be facilitated by an application programming interface (API) for creating an address for a block of content in a document identified through a location identifier as well as APIs for retrieving content from the created address and pushing or merging the content back to the created address. Access services including conversion and merge services can be used to provide the content blocks in a suitable format for various clients. A document view is described in which a plurality of content blocks are presented as a single document even though the content blocks may be retrieved using at least two uniform resource locators (URLs).

Abstract: A system is provided in which access to documents and collaboration across varied platforms and feature versions is supported. A conversion and merge services is described that enables a client device to display documents irrespective of the original file format and re-integrate into the original document the modifications of the displayed document. The displayed document (as a whole or in parts) can be imported and converted to the file format of the original document before the changes are compared and merged into the original document. A set of application programming interfaces are also provided that perform certain tasks, such as highlight, comment, or format.
