Abstract: Examples described herein generally relate to maintaining a snapshot of a multitier distributed file system. A snapshot directory volume of a directory volume can be created at least in part by copying, to the snapshot directory volume, metadata of the directory volume. Based on a file access request, it can be determined whether the file has not been snapshotted. If not, a snapshot file record of the file, and associated with the snapshot directory volume.

Abstract: An airfoil body for an aircraft extending from an inner end to an outer end, and between a leading edge and a trailing edge, comprising an airfoil skin, a planar sheet disposed below the airfoil skin including an array of transducer elements attached to the planar sheet comprising one or more of: (i) an array of semiconductor sensors not including solar cells; (ii) an antenna array and (iii) thermal transfer elements.

Abstract: An airfoil body for an aircraft extending from an inner end to an outer end, and between a leading edge and a trailing edge. The airfoil body comprises an internal structure and an airfoil skin covering the internal structure. The skin has a pressure side and a suction side, and the suction side includes a light transmitting portion. The internal structure includes an array of transduce elements attached to a planar sheet with the airfoil body. The present disclosure further relates to wings and aerial vehicles.

Abstract: A vehicle such as an aircraft on which a solar cell assembly is mounted on a surface of the space vehicle. The solar cell assembly may be prepared on an assembly fixture. The solar cell assembly may then be removed from the assembly fixture and positioned on a top surface of the streamlined body of the vehicle. In examples, the solar cell assembly comprises a first film, an array of solar cells on top of the first film, and a second silicone film deposited over the solar cells.

Abstract: A virtual secure mode is enabled for a virtual machine operating in a computing environment that is associated with a plurality of different trust levels. First, a virtual secure mode image is loaded into one or more memory pages of a virtual memory space of the virtual machine. Then, the one or more memory pages of the virtual memory space are made inaccessible to one or more trust levels having a relatively lower trust level than a launching trust level that is used by a virtual secure mode loader to load the virtual secure mode image. A target virtual trust level is also enabled on a launching virtual processor for the virtual machine that is higher than the launching trust level.

Abstract: The disclosure relates to an airfoil body for an aircraft extending from an inner end to an outer end, and between a leading edge and a trailing edge. The airfoil body comprises an internal structure and a skin covering the internal structure. The skin has a pressure side and a suction side, and the suction side includes a light transmitting portion. The internal structure includes an array of solar cells configured to receive solar light through the light transmitting portion. The present disclosure further relates to wings and aerial vehicles.

Abstract: Embodiments provide a method and system for transferring data between different computing devices. Specifically, a communication session is established between a first computing device and a second computing device. The communication session may be established using a first communication protocol. The first computing device creates a virtual memory object which is bound to one or more memory blocks of the first computing device. A path to the virtual memory object is generated and the path is transmitted to the second computing device using the communication session. The second computing device may then read or write data directly into/from the virtual memory object using a second communication protocol that is different from the first communication protocol. The data is written into and read from the virtual memory object using file system commands.

Abstract: A dispenser includes a dispenser body having an interior cavity, and an aperture that communicates with the interior cavity. The dispenser also includes a loading door and a lid. The lid engages a dispenser surface when in the closed position to thereby create a substantially gas impermeable seal. The dispenser further includes a mounting surface disposed within the interior cavity and proximal the aperture. The mounting surface includes a mounting interface that permits substantially gas impermeable mounting of a cartridge while permitting access to the cartridge from the exterior of the dispensing body through the aperture.

Abstract: An accessory clamp for use with a rod includes an accessory interface and a corresponding rod clamp. The accessory interface includes at least one of at least one accessory hook and at least one accessory T-slot. By one approach, at least one of the accessory hooks comprises a pivoting accessory hook. By one approach the rod clamp can comprise a universal rod clamp. As one example in these regards, the universal rod clamp can include a selectively variable gripping surface to accommodate a variety of rod diameters. By one approach the accessory interface and the corresponding rod clamp can pivot with respect to one another.
