Abstract: Memory devices and systems with programmable refresh order and stagger times are disclosed herein. In one embodiment, a memory device includes a first memory bank group and a second memory bank group. The memory device is configured, in response to a refresh command, to perform a first refresh operation on the first memory bank group at a first time and a second refresh operation on the second memory bank group at a second time after the first time. The memory device is further configured to perform, in response to a read or write command, a read or write operation on the first memory bank group, the second memory bank group, or both the first and second memory bank groups after beginning the first refresh operation and before completing the second refresh operation.

Abstract: Structural composite airfoils include a primary structural element, a secondary structural element defining the trailing edge of the structural composite airfoil, and a discrete leading edge structure defining the leading edge of the structural composite airfoil. The primary structural element includes an upper skin panel, a lower skin panel, and a middle C-channel spar that is coupled to the upper skin panel and the lower skin panel. The discrete leading edge structure is coupled to the upper leading edge end of the upper skin panel and to the lower leading edge end of the lower skin panel. The upper skin panel may include a first panel bend adjacent the discrete leading edge structure, and the lower skin panel may include a second panel bend adjacent the discrete leading edge structure.

Abstract: Rivet dispenser reloading systems and methods of use thereof are provided. A non-limiting embodiment of a rivet dispenser reloading system comprises a receiving member defining a channel therein, and a first gate. The rivet receiving member comprises a first port and a second port that communicate with the channel. The first port is configured to receive rivets. The second port is configured to selectively engage with a rivet dispenser and introduce rivets to the rivet dispenser. The channel extends between the first port and the second port and is configured to transport rivets from the first port to the second port in a series arrangement and in a preselected orientation. The first gate is in communication with the second port and is selectively positionable between a first configuration inhibiting movement of rivets through the second port, and a second configuration enabling movement of rivets through the second port.

Abstract: System, method, and apparatus for Internet Protocol (IP) based radio communications. One or more browser-based dispatch consoles connect to one or more Radio over IP (RoIP) gateway device over an untrusted network (e.g., the public Internet) using a Web Real-Time Communication (WebRTC) connection secured with SSL/TLS. Each RoIP gateway device provides an analog interface to the radio domain so as to communicate with one or more radio. This architecture avoids any ongoing connection to a centralized cloud-based server and maintains secure radio communications over the untrusted network. Each browser-based dispatch console accesses each RoIP gateway device from a standard web browser thus enabling portability across any platform that supports a browser.

Abstract: Memory devices and systems with improved command/address bus utilization are disclosed herein. In one embodiment, a memory device comprises a plurality of external command/address terminals and a command decoder. The plurality of external command/address terminals are configured to receive a command as a corresponding plurality of command/address bits. A first set of the command/address bits indicate a read or write operation. A second set of the command/address bits indicate whether to execute a refresh operation. The memory device is configured to, in response to the first set of command/address bits, execute the read or write operation on a portion of a memory array. The memory device is further configured to, in response to the second set of command/address bits, execute the refresh operation to refresh at least one memory bank of the memory array when the second set of command/address bits indicate that the refresh operation should be executed.

Abstract: A server receives a first hypertext transfer protocol (HTTP) from a client device that requests first and second items of content associated with a webpage and applies a defer directive to the second item. The server retrieves, from a database, via a single worker thread, first data associated with the first item and transmits a first message comprising the first data associated with the first item. The server retrieves, from the database, via the worker thread, second data associated with the deferred item and transmits a second message comprising the second data associated with the second item.

Abstract: Memory devices, systems including memory devices, and methods of operating memory devices are described, in which memory devices are configured to conditionally activate certain rows during refresh operations such that the memory devices can execute operations directed to the activated rows concurrently with the refresh operations. In some embodiments, the memory device receives an activate (ACT) command directed to a section of a memory bank while performing refresh operations for the memory bank. The memory device may carry out the ACT command if certain conditions are satisfied not to corrupt the data being refreshed. Subsequently, the memory device generates a signal to indicate the ACT command has been accepted to activate a row identified by the ACT command. Further, the memory device can perform subsequent access commands directed to the row, in parallel with the refresh operations.

Abstract: Structural composite airfoils include a front C-channel spar having an upper flange coupled to an upper skin panel, and a lower flange coupled to a lower skin panel. The lower skin panel includes a joggle adjacent a lower leading edge end, with the joggle being positioned forward of the front C-channel spar. An upper skin surface of the lower leading edge end faces an internal volume defined between the upper skin panel and the lower skin panel. A lower skin surface of the lower leading edge end faces an internal surface of the upper leading edge end of the upper skin panel, and the lower leading edge end of the lower skin panel is coupled to the upper leading edge end of the upper skin panel forward of the front C-channel spar. The leading edge has a bullnose shape defined by the upper skin panel.

Abstract: A connector to connect a center wing box to a bulkhead of an aircraft. The connector includes a panel with a first edge positioned at the center wing box, an opposing second edge positioned at the bulkhead, and a central section. A first flexible seal extends across the panel and provides for relative movement between the first edge and the central section. A second flexible seal extends across the panel and provides for relative movement between the second edge and the central section.

Abstract: Methods and apparatus are described for facilitating the client-side caching of media content based on one or more properties of the media content. Information relating to the cacheability of different types of content is communicated to the media player on a client device in the manifest or playlist employed by the media player to request fragments of the media content. The media player uses this information to make decisions about how to cache the corresponding content.
