Abstract: Methods for enabling hands-free selection of virtual objects are described. In some embodiments, a gaze swipe gesture may be used to select a virtual object. The gaze swipe gesture may involve an end user of a head-mounted display device (HMD) performing head movements that are tracked by the HMD to detect whether a virtual pointer controlled by the end user has swiped across two or more edges of the virtual object. In some cases, the gaze swipe gesture may comprise the end user using their head movements to move the virtual pointer through two edges of the virtual object while the end user gazes at the virtual object. In response to detecting the gaze swipe gesture, the HMD may determine a second virtual object to be displayed on the HMD based on a speed of the gaze swipe gesture and a size of the virtual object.

Abstract: The present disclosure is directed to a monitoring system for automatically inferring, without human modelling input or information regarding actual physical network connectivity, a service architecture of a widely distributed service operated by an Infrastructure-as-a-Service (IaaS) tenant but deployed on a set of virtual resources controlled by an independent IaaS provider. The monitoring system can collect infrastructure metadata and/or system-level metric data characterizing the set of virtual resources from the IaaS provider, and automatically infer from the metadata and/or metric data how the virtual resources should be organized into groups, clusters and hierarchies. The monitoring system can automatically infer this service architecture using naming conventions, security rules, software types, deployment patterns, and other information gleaned from the metadata and/or metric data. The monitoring system can then run analytics based on this inferred service architecture to report on service operation.

In some embodiments, the 3? end of both the sense and anti-sense strand further comprise, in 5? to 3? order: a spacer; a second phosphate or modified internucleoside linker; and a 3? end cap. The two strands can have the same or different spacers, phosphates or modified internucleoside linkers, and/or 3? end caps. The strands can be ribonucleotides, or, optionally, one or more nucleotide can be modified or substituted. Optionally, at least one nucleotide comprises a modified internucleoside linker.

Abstract: Methods for controlling the display of content as the content is being viewed by an end user of a head-mounted display device (HMD) are described. In some embodiments, an HMD may display the content using a virtual content reader for reading the content. The content may comprise text and/or images, such as text or images associated with an electronic book, an electronic magazine, a word processing document, a webpage, or an email. The virtual content reader may provide automated content scrolling based on a rate at which the end user reads a portion of the displayed content on the virtual content reader. In one embodiment, an HMD may combine automatic scrolling of content displayed on the virtual content reader with user controlled scrolling (e.g., via head tracking of the end user of the HMD).

Abstract: Embodiments of the invention describe systems and methods for malicious software detection and analysis. A binary executable comprising obfuscated malware on a host device may be received, and incident data indicating a time when the binary executable was received and identifying processes operating on the host device may be recorded. The binary executable is analyzed via a scalable plurality of execution environments, including one or more non-virtual execution environments and one or more virtual execution environments, to generate runtime data and deobfuscation data attributable to the binary executable. At least some of the runtime data and deobfuscation data attributable to the binary executable is stored in a shared database, while at least some of the incident data is stored in a private, non-shared database.

Abstract: A method of producing a ceramic weld, including identifying a ceramic first surface and a ceramic second surface to be bonded together, maintaining a non-oxidizing atmosphere over the first and second surfaces, and engaging the first and second surfaces to define a joint. An arc is generated between an electrode and the joint to create a liquid phase, and the liquid phase is cooled to yield a solid fusion layer, wherein the first and second surfaces are joined in the fusion layer.

Abstract: In some examples, a technique may include positioning a first part comprising a ceramic or ceramic matrix composite and a second part comprising a ceramic or a CMC adjacent to each other to define a joint region at the interface of the first part and the second part. In some examples, the joint region may be heated using at least one of a laser or a plasma arc source to heat the joint region to an elevated temperature. The first and second parts may be pressed together and cooled to join the first and second parts at the joint region. In other examples, a solid braze material including a filler material and a metal or alloy may be delivered to the joint region and locally heated to cause a constituent of the filler material and a constituent of the metal or alloy to react. When reacted, the constituents may form a solid material, which may join the first and second parts.

Abstract: A reach back secure communications terminal includes a modem to satellite interconnect board that captures DTMF tones, demodulates encrypted modem information, and converts both into an ASCII string for presentation to a data port of a satellite phone, allowing out-of-band control of a non-secure satellite system (e.g., AT command control of a data port) by a user on a secure side of an encryption device, by including the ability to interpret control signals and control the satellite system appropriately. A false dial tone is presented to the encryption device, and the data stream coming from the encryption device is monitored for the presence of dual-tone, multi-frequency (DTMF) tones representing control signals, the DTMF tones are converted to ASCII characters, which are in turn received as control signals by the satellite phone, allowing control of the functions of the satellite system directly from the secure side of the encryption device.
