Abstract: An apparatus calculates a block vector difference (BVD) between a block vector (BV) and a block vector predictor (BVP). The apparatus determines each of a plurality of BV candidates based on a sum of the BVP and a different one of a plurality of BVD candidates. Each of the plurality of BVD candidates comprises: a first and a second component magnitude of the BVD; and a different combination of signs for the first and second component magnitudes. The apparatus determines validities of the plurality of BV candidates based on values of samples, stored in a reference memory, of reference blocks indicated by the plurality of BV candidates. The apparatus signales, in a bitstream, a sign for at least one of the first and second component magnitudes of the BVD based on the validities of the plurality of BV candidates.

The opening is configured to receive an airfoil segment of the stator vane assembly. A forward portion of the main body extends between the forward end and the opening. An aft portion of the main body extends between the opening and the aft end. A cooling circuit is defined within the platform. The cooling circuit includes a first plenum defined in the forward portion, and at least one re-use plenum defined in the aft portion and separated from the first plenum. The cooling circuit further includes a connecting channel that fluidly couples the first plenum and the at least one re-use plenum.

Abstract: Technologies described herein relate to conflict detection in a geo-replication architecture that includes several computing systems, where a database is asynchronously updated at the several computing systems and update notifications are transmitted amongst the computing systems to ensure that the database is replicated across the computing systems. Partial vector clocks, instead of full vector clocks, are used to update the database at different computing systems, thereby using fewer network resources when compared to conventional approaches. Further, less than whole vector clocks can be persisted with records stored on disk, thereby using fewer disk resources when compared with conventional approaches.

Abstract: This disclosure describes systems and techniques for using controlling access to user information using ephemeral user identifiers. In one aspect, a method includes determining, for a given domain, engagement by a user with content provided by the given domain for display by an application at a client device of the user. A determination is made, based on the engagement by the user, to extend, for the given domain, a linkage between user identifiers for a user of the application. In response to determining to extend, for the given domain, the linkage between the user identifiers for the user of the application, one or more future domain-specific ephemeral user identifiers for the user and the given domain are obtained. An attestation record that includes a current domain-specific ephemeral user identifier and the one or more is generated and sent to the given domain.

Abstract: Methods and systems are described herein for facilitating installation of cables within datacenters without signals being sent/received from outside the datacenter buildings. In particular, the mechanism for facilitating installation of cables within datacenters may include scanning cable codes (e.g., QR codes, bar codes, near field communication (NFC) codes, radio frequency identification (RFID) codes, etc.) and retrieving path information for scanned cable codes. The mechanism then proceeds to track the installation process by scanning codes located throughout a datacenter to verify that the cable installation is proceeding correctly. In instances where a scanned code does not match a code that is expected, based on an order within the path information, an error message is generated indicating that there may be a problem with the cable installation.

Abstract: A lighting system includes a wake-up light source to emit a wake-up light beam and a plurality of luminaires located in a space. A respective luminaire includes an illumination light source to emit illumination lighting for the space, a light sensor to detect light, a wireless transceiver configured for wireless communication, and a memory. The respective luminaire further includes a processor coupled to the light sensor, the wireless transceiver, and the memory. The respective luminaire further includes wake-up programming in the memory. Execution of the wake-up programming by the processor causes the respective luminaire to: (a) detect a plurality of light measurements above a light threshold; (b) determine whether the plurality of light measurements are in accordance with a pattern; and (c) in response to determining the plurality of light measurements are in accordance with the pattern, enter a beaconing mode.

Abstract: Devices, systems, and methods are directed to controlling lifting gas in a volume defined by an inflatable structure of an aircraft. For example, controlling lifting gas in the volume of the inflatable structure may account for variations in ambient and tactical conditions experienced by the aircraft over the course of flight, as may be useful for lifting the aircraft to a target altitude and/or carrying out a particular mission. Additionally, or alternatively, controlling lifting gas in the volume of the inflatable structure may facilitate lifting the aircraft using lifting gas generated by reacting stable materials with one another at a launch site in the field. As an example, aluminum may react with water to form a lifting gas including hydrogen and steam. As the steam condenses to water in the inflatable structure, a valve may expel water from the inflatable structure to assist in maintaining buoyancy of the aircraft.

Abstract: Methods and apparatus to monitor media content at a content display site are described. An example apparatus includes processor circuitry to execute computer readable instructions to: estimate a first audience size associated with unmeasured locations based on distributed census-based page views and a measured panel data; generate a virtual panel based on the first audience size to enable more accurate estimation of traffic from the unmeasured locations by weighting second panelists associated with the unmeasured locations and reweighting a subset of the second panelists; and determine additional activity not represented by the measure panel data; and calculate an online audience based on a measured location audience, the virtual panel, and the additional activity.

Abstract: An identification station is operable to obtain digital representations of biometrics for people and communicate these digital representations of biometrics over one or more networks to an identification system device in order to identify the people for a variety of different purposes. The identification station also stores data related to previous biometric identifications in a local cache for one or more time windows. Upon obtaining a digital representation of a biometric, the identification station may first check if the digital representation of the biometric corresponds to data in the local cache. If so, the identification station may omit communicating with the identification system device. Otherwise, the identification station may communicate with the identification system device to identify the person, as well as store the digital representation of the biometric in the local cache for the one or more time windows.
