Abstract: Interference-based augmented reality hosting platforms are presented. Hosting platforms can include networking nodes capable of analyzing a digital representation of scene to derive interference among elements of the scene. The hosting platform utilizes the interference to adjust the presence of augmented reality objects within an augmented reality experience. Elements of a scene can constructively interfere, enhancing presence of augmented reality objects; or destructively interfere, suppressing presence of augmented reality objects.

Abstract: Systems and methods of determining languages of users in networked environments are provided herein. A data processing system having one or more processors coupled with memory can receive, from a client device, a request for content identifying an account profile. The data processing system can determine, using a log record identifying activities of the account profile, a first set of candidate languages. The data processing system can identify a plurality of information resources to be presented in accordance with a ranking. The data processing system can determine a second set of candidate languages from the plurality of languages based on content in each information resource and a corresponding ranking of each information resource. The data processing system can identify a set of languages included in both the first set of candidate languages and the second set of candidate languages.

Abstract: Errors that affect a quantum computer can be efficiently measured and characterized by placing the quantum computer in a highly-entangled state such as a Greenberger-Horne-Zeilinger (GHZ) state, accumulating quantum errors in the highly entangled state, and then measuring the accumulated errors. In some approaches, the error characterization includes measuring parity oscillations of the GHZ state and fitting a quantum error model to a power spectrum of the parity oscillations. The fitted quantum error model can be used to select a suitable fault-tolerant error correction scheme for the quantum computer given its environmental noise.

In various embodiments, the system includes a device management system operatively coupled to a merchant system. According to particular embodiments, the device management system: 1) receives a first payload correspond to a device from the merchant system, the first payload including data in a particular format; 2) creates a fingerprint for the device by parsing the first payload and creating a record of a section format for each of one or more distinct sections of the particular format; and 3) comparing a format of each subsequent payload that corresponds to the device to the fingerprint for the device to determine whether the device has been compromised.

Abstract: Solutions for improving parallelization of computer programs interleave machine instruction placement in memory. A compiler decomposes a software loop in stages to interleave instructions such that, for contiguous sets of instructions having some minimum length (e.g., each set has at least two to four instructions), instructions within a set have no dependency on prior instructions within that set. This enables the compiled program to be more fully parallelized—for example, either by a superscalar processor executing the compiled program, or by the compiler turning each set of instructions into a very long instruction word (VLIW)—to automatically benefit from the disclosed interleaving of instructions that eliminates dependencies.

Abstract: An electronic device incorporates, and method and computer program product provide improved auto white balance (AWB) performance. The electronic device receives first image content from a first image capturing device of an electronic device. The electronic device receives second image content from a second image capturing device. The second image capturing device has a second field of view (FOV) that differs from a first FOV of the first image capturing device. The controller identifying, during an image capturing process for a target image within the first FOV, whether a condition exists that causes a distortion in a white balance of the first image content. In response to identifying that the condition exists, the controller captures the second image content within the second FOV, determining an AWB value for the second image content, and automatically adjusting the first image content using the AWB value for the second image content.

Abstract: Systems, methods, and computer program products for providing and managing a lighting system. A lighting device of the system is configured to receive an activation signal from a user interface of the lighting device, an external communication device, or another lighting device. In response to receiving the activation signal, and if certain operational conditions are met, the lighting device may activate a light source and transmit another activation signal. Additional lighting devices receiving the activation signal from the first lighting device may also activate their light sources and retransmit the activation signal. Data carried by the activation signals and signals received from one or more sensors in each lighting device may be used by the lighting device to determine whether to activate its light source, and one or more characteristics of the light to be emitted.

Abstract: A spacecraft trash disposal apparatus and method are disclosed. The spacecraft trash disposal apparatus includes an airlock, an inflatable trash enclosure holding trash, and a pressure regulating system. The spacecraft trash disposal apparatus permits wet and dry trash to be transported from the inside of a spacecraft via the inflatable trash enclosure holding the trash. The inflatable trash enclosure is ejected to the surrounding vacuum of space without causing trash or liquids to escape from the inflatable trash enclosure. The pressure regulating system permits reduction of pressure inside the inflatable trash enclosure from typically atmospheric to a lower pressure while the airlock is depressurizing without going to a full vacuum. This lower pressure is such that, at a given temperature, the liquid trash is prevented from boiling. The lower pressure permits a lightweight inflatable trash enclosure for low cost spacecraft trash disposal.
