Abstract: A method of adding a power feed to electrical systems includes coupling a set of input lines to a power source such that the input lines are connected to at least one phase of AC power from the power source, and coupling a set of backfeed lines to an output receptacle in a power distribution unit. The output receptacle may be connected in parallel with at least one other output receptacle that is supplying primary power to systems in the data center. The set of backfeed lines and the set of input lines may be tested to determine a match between a pair of lines in the set of backfeed lines and a pair of lines in the set of input lines. Determining the match may include matching the phase of the pair of backfeed lines with the phase of the pair of input lines.

Abstract: A database may provide a visualization of restoration operation granularity. Information may be obtained describing possible restoration points within a given period of time for a database. The information may include a respective state of the database associated with a point in time and a respective restoration operation type for the possible restoration points. A graphical representation may be generated illustrating the possible restoration points ordered within the given time period according to the points in time associated with the respective states of the database. The graphical representation may be provided via network-based interface to a client of the database. The graphical representation of the possible restoration points may be updated in response to changes to the given time period or database volume events that modify the possible restoration points.

Abstract: Aspects of fluorescent ink printing, cutting, and apparel assembly are described. In one example, a system includes a textile printer, a textile cutter, and a computing device that arranges panels and develops print features related to textile products. The computing device can assign certain print features to be printed using fluorescent inks. The computing environment can then instruct a textile printer to print textile panels, for example, along with the print features, using the fluorescent inks. Once the panels are printed, ultraviolet (UV) light sources can be used to create a fluorescent reflection from the fluorescent inks. The fluorescent reflection can be captured by image sensors to generate instructions to cut the panels out from the textile sheet. The reflection can also be used as assembly notations for reference by sewing workers or automated sewing systems.

Abstract: Systems, methods and devices for automatically cropping images taken by an electronic device in order to determine the identity of a product contained in the image are described herein. A number of different techniques may be applied to perform the automatic cropping, including a focus sweep technique in which a first image is analyzed for the presence of a human being and then a second image is taken in a plane closer to the camera than the first image. The two frames are analyzed and a resultant image is provided that avoids the regions in which the human being is present to focus on the product. In other embodiments, a motion vector calculation is made between two images in which an individual is holding a product. The motion vectors related to the human are removed and a bounding box is calculated to reduce the size of the image to include a higher percentage of the product, such that the product can be more easily identified.

Abstract: Systems and methods for authentication generate keys from secret credentials shared between authenticating parties and authenticators. Generation of the keys may involve utilizing specialized information in the form of parameters that are used to specialize keys. Keys and/or information derived from keys held by multiple authorities may be used to generate other keys such that signatures requiring such keys and/or information can be verified without access to the keys. Keys may also be derived to form a hierarchy of keys that are distributed such that a key holder's ability to decrypt data depends on the key's position in the hierarchy relative to the position of a key used to encrypt the data. Key hierarchies may also be used to distribute key sets to content processing devices to enable the devices to decrypt content such that sources or potential sources of unauthorized content are identifiable from the decrypted content.

Abstract: Online retailers may operate one or more services configured to detect requests generated by automated agents. A CAPTCHA may be transmitted in response to requests generated by automated agents. The CAPTCHAs may be included in a modal pop-up box configured to be displayed by a client application displaying a webpage to a customer of the online retailer. Furthermore, the CAPTCHAs included in the modal pop-up box may be rendered inactive and caused not to be displayed by client application executing the webpage. Rendering the CAPTCHAs inactive may provide an additional signal which may be sued to update one or more automated agent detection models.

Abstract: A pickup location may be enabled to continue to operate when communication over a network is not available by preemptively synchronizing certain data. For the delivery of an item, order data such as the expected tracking identification for an item may be sent to the pickup location before the item is delivered. An access code that will be used by the user for retrieving the item from a storage compartment at the pickup location may also be generated and synchronized between the pickup location and a remote computing resource before the item is delivered. A delivery of an item as confirmed by a carrier may be reported to a user when communication with the pickup location is unavailable if the carrier meets a certain confidence threshold requirement based on past performance.

Upon receipt of an input corresponding to the selection of the graphical icon, the browser deletes information collected while accessing the first network resource and accesses the second network resource.

Abstract: A customer submits a set of preferences including hardware specifications for instantiating a virtual machine instance. The virtual machine instance may be instantiated in a physical host computer system that does not conform to the set of preferences. The virtual computer system service may be configured to evaluate the specifications of the available physical host computer systems to determine whether any of the available physical host computer systems conform to the set of preferences. Accordingly, the virtual computer system service may further evaluate the available physical host computer systems to determine whether available physical host computer systems comprise available slots for instantiating the existing virtual machine instance. If the one or more available physical host computer systems have available slots, the virtual computer system service may migrate the existing virtual machine instance to an available physical host computer system in order to fulfill the customer request.
