Abstract: In some examples, an unmanned aerial vehicle (UAV) may include a stereo camera including two cameras. To maintain proper alignment of the stereo camera as the UAV moves about, a management device may access calibration information for the stereo camera and receive sensing information indicating movement of the two cameras relative to each other. Based at least in part on the calibration information and the sensing information, the management device may instruct an actuator to move one of the two cameras to the proper alignment or may rectify frames captured by the two cameras to return to the proper alignment.

Abstract: Disclosed herein is a method including receiving, from a user application, data to be transmitted from a source address to a destination address using a single connection through a network; and splitting the data into a plurality of packets according to a communication protocol. For each packet of the plurality of packets, a respective flowlet for the packet to be transmitted in is determined from a plurality of flowlets; a field in the packet used by a network switch of the network to route the packet is set based on the determined flowlet for the packet; and the packet is sent via the determined flowlet for transmitting through the network.

Abstract: A network protocol is provided to identify and authenticate devices from different vendors that are deployed in a network. Each vendor is provided a vendor key unique to the vendor by a network management server. A vendor server associated with the vendor provisions a device with a first hash value generated using the vendor key among other device attributes. When the device is deployed in the network, the network management server queries the device. The device generates a second hash value using the first hash value and sends it in a response to the network management server. The network management server computes a local hash value using the vendor key and the attributes received from the response. The network management server authenticates the device if the local hash value matches with the second hash value.

The first and second conveyors are coupled to one another such that the inner sides are spaced closer to one another than the outer sides and the first and second conveyors are angularly offset from one another. The transfer system also has a movement system that moves the conveyor system along at least one of a vertical direction, and a second direction so as to align the conveyor system with another conveyor system.

Abstract: A method for processing packet data in a service provider environment includes, by a network-enabled data processing device within a server computer of the service provider environment, receive packet data including header information and payload information. The packet header information can be separated from the payload information.

Transforming instructions and at least one address of one or more storage locations can be received from the processor, based at least in part on the header information. The payload information can be transformed based on the transforming instructions. The transformed payload information can be stored in the one or more storage locations based on the at least one address.

Abstract: A cluster formation engine invokes generation of an automatically scalable group (ASG) of virtual machine instances, where the ASG is associated with one or more applications to be run in a cloud computing environment. The cluster formation engine detects a failure to generate a first virtual machine instance to be included in the ASG, and completes the generation of the ASG without including the first virtual machine instance in the ASG.

Abstract: Described are systems, methods, and apparatus for generating motion extracted images having a high dynamic range (“HDR”) based on image data obtained from one or more image sensors at different times. The implementations described herein may be used with a single image sensor or camera that obtains images at different exposures sequentially in time. The images may be processed to detect an object moving within the field of view and pixel information corresponding to that moving object extracted. The non-extracted image data may then be combined to produce a motion extracted HDR image that is substantially devoid of the moving object.

Abstract: Security controls applied to a set of data, such as a data volume, can be recommended based on comparing the contents of the data set against those of other data sets and locating other data sets with the same or similar data. Security controls applied to those other data sets, but not applied to the set of interest, can be recommended for application to the data set. In order to protect customer data, the data to be compared can be sampled from the data set and analyzed for aspects such as present patterns, structures, or data types. In some embodiments various derivations can be generated, as may include hashes, checksums, or summaries based on the underlying data, and these derivations can be compared for purposes of finding data sets including similar data. Security controls can be recommended for tasks such as data placement, storage, or migration.

Abstract: A virtual private network (VPN) endpoint node is implemented on multiple virtual machines in a provider network. One or more virtual machines execute a packet aggregator. One or more other virtual machines implement cryptographic units. The packet aggregator is configured to distribute incoming encrypted packets from a secure tunnel across the plurality of cryptographic units. Each cryptographic unit is configured to decrypt incoming encrypted packets from the packet aggregator and to encrypt outgoing plaintext packets for transmission across the secure tunnel. The packet aggregator also may assign a sequence number to an outgoing plaintext packet, create a tunneled packet including the sequence number in a header of the tunneled packet and including the plaintext packet in tunneled packet, select one of the cryptographic units, and forward the tunneled packet to the selected cryptographic unit.

Abstract: In a provider network, a request is received for diagnostic information for a computing resource. In response to the request, diagnostic information from the computing resource is accessed via an out-of-band communication channel. The diagnostic information is stored for fault analysis. The out-of-band communication channel is operative when the one computing resource is not in a normal operating state.

Abstract: A system processes a video stream to identify an activity performed by a subject. The system examines the video segment for the presence or absence of an object that is correlated with the activity. If the object is found, and if the object is positively correlated with the detected activity, a confidence level associated with detecting the activity is increase. If the object is found, and if it is negatively correlated with the activity, the confidence level is decreased. In other examples, absence of an object may be positively or negatively correlated with the activity. In one embodiment, the system may detect a number of alternative activities, and may use the presence or absence of various objects to determine the most likely activity being performed. In another embodiment, the system may use the presence of various objects to narrow the set of activities that are searched for.
