Abstract: An electronic device can utilize one or more sensors and/or imaging elements to determine the relative position of at least one light source relative to the device. In various embodiments, occlusions can be used to cause shadows to be cast on certain sensors. By determining the relative position of each occlusion relative to the sensor, the device can determine an approximate direction of the light source. Utilizing the relative position of a light source, the electronic device can properly light or shade a graphical object to be rendered by the device or otherwise process image information captured by the device.

Abstract: Described herein are systems and techniques for periodically projecting content onto a display medium that is configured to display images for a finite amount of time, during which time the images decay until the image substantially or entirely disappears from the display medium. That is, the systems and techniques may project light onto the display medium, with the light energizing particles of the display medium to display a predefined image.

Abstract: Approaches enable a service such a network optimization service of a computing device (e.g., a mobile phone, table computer, etc.) or other electronic device to monitor certain conditions of the device, such as device location, to determine a region in which the device is operating in. The device location can be used to determine a region in which the device is operating, and based at least on that region, a group of frequencies (e.g., a band group) including at least a subset of band frequencies and technologies that the device supports can be determined. The device can then search bands/technologies from the band group to determine a network provider (e.g., a public land mobile network (PLMN)) from which to gain telecommunication service access.

Abstract: Various embodiments provide a method for randomly selecting a region on a map for testing and a map of the region can be generated using multiple map rendering engines. A screenshot of each of the generated maps can be obtained and text associated with map labels, such as street, city, and attraction names, can be recognized using an optical character recognition (OCR) engine. At this point, the recognized text from each rendering engine can then be compared to identify at least one error or inconsistency. In at least one embodiment, categories of errors that need most attention in the specific geographic areas can be identified and a human quality assurance tester can isolate these instances and narrow down the same to identify the rendering or data problem.

Abstract: When a touchscreen input device is in proximity with a first computing device, the touchscreen input device can send an identifier to the first computing device.

When possible root causes are ranked, notifications may be issued to alert administrators or other systems of the anomaly and the likely root causes.

Abstract: Described herein are system and methods for mitigating index contention issues in databases. The database server may generate additional storage locations to prevent overloading one or more current storage locations. A variety of database conditions may be used to trigger an increase or decrease in storage locations. In one embodiment, more storage locations may be generated when the amount of data records waiting to be written at a storage location exceeds or equals a threshold amount. Likewise, the database server may reduce the amount of current storage locations when the amount of data records is less than a threshold amount. The record identifiers may incorporate a location reference for their designated storage location. The reference may be a string that includes numbers, letters, or a combination thereof.

Abstract: A session identifier is used during negotiation of a secure connection between a client and an endpoint that includes both session information and client identification information. For example, a client connects to a load balancer using transport layer security (TLS). The load balancer may pass client information, such as session information, on to an application server that determines client information to put in a TLS session identifier. The application may send the client information to include in the TLS session identifier back to the load balancer. The load balancer may combine TLS session information for resuming TLS communications and client information for identifying the client into the session identifier. The session identifier may be passed to the client for use in later communication. TLS negotiation between the client and the load balancer may be completed and a secure connection begun. The application may monitor actions performed by the client.

Abstract: A method for provisioning digital certificates in a compute service environment may include authorizing a customer entity for using and/or controlling a network resource in the compute service environment. Upon completing the authorization, a digital certificate may be issued to the customer entity. The digital certificate may be associated with the network resource and may be issued for a limited duration period. The use and/or control of the network resource by the customer entity may be monitored. Reissuance of the digital certificate may be conditioned on whether the customer entity is still using and/or controlling the network resource in the compute service environment. If the customer entity is still using and/or controlling the network resource in the multi-tenant environment, the digital certificate may be automatically reissued for another limited duration period. The automatically reissuing may take place without receiving a certificate reissue request from the customer entity.
