Abstract: Disclosed techniques relate to caching tenant encryption keys for a multi-tenant database. In some embodiments, a computing system encrypts data for a database in a multi-tenant database system using encryption keys assigned to respective tenants that are using the database. The computing system may store the encryption keys in a cache and, in response to a key rotation request for a first tenant, invalidate an entry in the cache for the first encryption key of the first tenant. The computing system may block writes for the first tenant until a new key is cached (e.g., based on retrieval from a key management system). In various embodiments, disclosed techniques may reduce encryption latency.

Abstract: System includes a controller configured to obtain one or more of a route parameter or a vehicle parameter from discrete examinations of one or more of a route or a vehicle system. The route parameter is indicative of a health of the route over which the vehicle system travels. The vehicle parameter is indicative of a health of the vehicle system. The discrete examinations of the one or more of the route or the vehicle system separated from each other by one or more of location or time. The controller is configured to examine the one or more of the route parameter or the vehicle parameter to determine whether the one or more of the route or the vehicle system is damaged. The system also includes examination equipment configured to continually monitor the one or more of the route or the vehicle system responsive to determining that the one or more of the route or the vehicle is damaged.

Abstract: A virtual browsing experience may be implemented that allows a user to move a mobile device within a physical environment in order to control browser navigation to different items on an associated display. The virtual browsing experience improves the user's ability to recall where previously-viewed items are located in the virtual browsing environment. In some embodiments, a mobile device may determine its position and/or orientation in a physical environment, and when movement of the mobile device is detected, a user interface on an associated display may digitally navigate through multiple items according to the position and/or orientation of the mobile device. The position and orientation of the mobile device may be determined from position information or data obtained by a sensor device of the mobile device, and appropriate subsets of items can be determined for display based on detected movement of the mobile device.

Abstract: A camera system and method capture image data with a camera, a data storage device electrically connected to the camera and configured to store the video data and/or a communication device electrically connected to the camera and configured to communicate the image data to a system receiver located remote from the camera. The system receiver may be located onboard a vehicle such that an operator can carry the camera off board the vehicle and communicate the image data back to the vehicle, when performing, for example, work on the vehicle or inspecting the vehicle or the environs of the vehicle.

Abstract: A system for providing low-latency compute capacity is provided. The system may be configured to route incoming code execution requests based on user indications to use specific containers running on a plurality of virtual machine instances. The system may be configured to process a code execution request, identify, based on the user indication that a specific container previously used to handle a request of similar type is to be used for handling the code execution request, and cause the code execution request to be handled using the specific container.

Abstract: A retractable load carrier system for a vehicle comprising a rail assembly comprising a first rail and a second rail, wherein each rail is configured to be mounted to a vehicle roof. The system can further include a rack assembly comprising a first support member and a second support member generally parallel to each other, wherein the first support member and second support member can be coupled together with at least one cross members, wherein the rack assembly has a first end and a second end, wherein both the first and second end can include a handle portion. A locking means can be coupled to the handle portion of the rack assembly, wherein the locking means comprises a plurality of engagement members configured to latch to engage the grooved portion of the rail assembly or the pins are configured to engage the pinion portion of the rail assembly.

Abstract: A locomotive speed determination system and method receive image data of a field of view of a camera operably disposed onboard a locomotive. A speed and/or heading of the locomotive are determined as the vehicle is moving based at least in part on one or more differences in the image data. In one aspect, pixel intensities in different images or frames may be examined to identify one or more features of interest in the images or frames. Movement of the one or more features of interest in the images or frames is correlated to movement of the locomotive along the route, and the time difference between when the images or frames are obtained can be used to determine the locomotive speed.
