Abstract: Devices, systems and methods are disclosed for allowing a mobile device to roam from a first frequency band to a second frequency band for a dual band access point when a signal strength associated with the first frequency band improves. For example, the mobile device may store a first signal strength associated with the first frequency band when the mobile device first connects to the first frequency band and may monitor subsequent signal strengths to determine if they exceed the first signal strength. When a subsequent signal strength exceeds the first signal strength, the mobile device may use this as an indication that the mobile device is closer to the access point and within range of the second frequency band. The mobile device may then detect and connect to the second frequency band.

Abstract: Methods and systems are provided to enable access control based on credential properties.

For instance, a user's access rights may be gradually restricted after an initial expiration time and towards a final expiration time. In an example, such access control may be implemented by a client application or client website of the authentication service. Alternatively or additionally, such access control may be implemented by an authorization service used by the client application or client website.

Abstract: A method for fabricating electronic displays comprises placing a fluoropolymer layer on a support plate for the electronic display device and etching the fluoropolymer layer. Etching changes a surface of the fluoropolymer layer so that the fluoropolymer layer becomes less hydrophobic. Pixel walls are formed on the hydrophilic surface of the fluoropolymer layer to form an array of electrowetting display elements. The fluoropolymer layer is subsequently immersed in a vapor or a liquid that is heated to heat the surface of the fluoropolymer layer. Such immersion allows the surface of the fluoropolymer layer to reflow and to become more hydrophobic.

Abstract: Techniques for singleton coordination in an actor-based system are described herein. In some examples, one or more actors within an actor based system may be designated as singleton actors. Each singleton actor is permitted to have only a single associated instance in the actor-based system. In some cases, when multiple executing instances (i.e., duplicates) of a singleton actor are detected, the duplicates may be resolved, for example, such that no more than a single instance of the singleton actor is retained. In some examples, one or more singleton coordinators may be responsible for selecting one or more hubs on which to generate new or re-generated singletons, monitoring existing singletons to ensure that they continue to execute, and re-generating existing singletons after termination.

Abstract: Technologies are described herein for distributed storage and retrieval of directed acyclic graphs, such as version control graphs maintained by a version control system.

The index entry for each object includes a unique identifier for the object and data identifying the location of the object in the distributed object store. The index may be utilized to traverse the directed acyclic graph and to obtain all or a portion of the objects in the directed acyclic graph from the distributed object store.

Abstract: Techniques are described for promoting content items in a page to load in a different order than the order in which they were initially designated to load in the page source. A page may include critical content items designated to load earlier than non-critical content items. In instances where there is a delay due to latency in generating or retrieving the critical content items, one or more non-critical content items may be promoted to load earlier than initially designated. Promotion may include incorporating metadata based priority indicators, such as attributes, into the tags for content items to suggest an order in which the content items may be requested by a user device. By promoting non-critical content items to load during the period in which the loading of the page may otherwise be stalled, overall page load times may be reduced.

The computing device may then access the traffic condition, and then render a visual representation of traffic patterns on a digital map. The traffic conditions may also be packaged as arrays within a picture or texture file.

Abstract: Techniques for altering audio being output by a voice-controlled device, or another device, to enable more accurate automatic speech recognition (ASR) by the voice-controlled device. For instance, a voice-controlled device may output audio within an environment using a speaker of the device. While outputting the audio, a microphone of the device may capture sound within the environment and may generate an audio signal based on the captured sound. The device may then analyze the audio signal to identify speech of a user within the signal, with the speech indicating that the user is going to provide a subsequent command to the device. Thereafter, the device may alter the output of the audio (e.g., attenuate the audio, pause the audio, switch from stereo to mono, etc.) to facilitate speech recognition of the user's subsequent command.
