Abstract: A method for determining positions of moving targets in unbiased three-dimensional (3D) measurement spaces using data collected against the moving targets by an electro-optical or infrared (EO/IR) sensor, the method comprising receiving data collected from electrical signals reflected from the moving targets in a first focal plane of the EO/IR sensor at a first time point, receiving data collected from electrical signals reflected from the moving targets in a second focal plane of the EO/IR sensor at a second time point, generating two-dimensional (2D) measurement data for the moving targets in the first and second focal planes, calculating 3D target velocities for the moving targets using the 2D measurement data, and estimating local 3D positions within a first unbiased 3D measurement space for the moving targets at the first and second time points based on the 3D target velocity.

Abstract: Disclosed are various embodiments for transmitting a plurality of files of a plurality of file systems associated with a corresponding plurality of users to each one of the users. In one embodiment, a jukebox service identifies files from file systems associated with each user requesting to consume the transmitted content. In one embodiment, the jukebox service identifies the files based in part on a plurality of disc jockey preferences provided by a disc jockey. The jukebox service then generates a jukebox playlist of the identified files having an order that is generated based at least in part on a playback profile associated with each one of the files. For instance, the playback profile may describe a playback frequency of the respective file. The jukebox service may then transmit the files over a network to clients of requesting users according to the order established by the jukebox playlist.

Abstract: System and method for sensor alignment. In one example, a reimaging optical system includes reimaging foreoptics positioned to receive and reimage incident electromagnetic radiation to produce an intermediate image plane and output an optical beam of the received incident electromagnetic radiation, an imaging optical apparatus positioned to receive the optical beam and focus the electromagnetic radiation of the optical beam onto a first focal plane, a first imaging sensor positioned at the first focal plane and configured to produce a first image responsive to receiving the electromagnetic radiation of the optical beam, an alignment object selectively positioned at the intermediate image plane and configured to superimpose an alignment tool upon the first image, and a controller coupled to the first imaging sensor and configured to perform an alignment process for the first imaging sensor based on at least a position of the alignment tool in the first image.

Abstract: Disclosed are various embodiments of a method and system for providing a simplified listing process for sellers. A computing device obtains contact information for a seller and a representation of an item that may be purchased through an electronic marketplace. This information is obtained without requiring the seller to register with the electronic marketplace. Using the representation of the item, a seller listing for the item in the electronic marketplace is generated. The seller is notified through the contact information when a buyer purchases the item from the seller through the generated seller listing.

Abstract: Disclosed are various embodiments for replicating service requests. A service request is obtained from a client. A primary service and a secondary service are determined based at least in part on the service request and a routing configuration. The secondary service corresponds to another version of the primary service. The service request is routed to the primary service and potentially replicated to the secondary service. A service response to the service request is obtained from the primary service and then sent to the client.

Abstract: Disclosed are various embodiments for pre-fetching data from a service in advance of obtaining an asynchronous callback for the data from a client. It is determined whether a network page requested by a client is configured to prompt the client to initiate an asynchronous callback for data that may be pre-fetched. The data is pre-fetched from a service before obtaining the asynchronous callback for the data from the client. The data that has been pre-fetched from the service is sent to the client in response to obtaining the asynchronous callback for the data from the client.

Abstract: An Internet-based service configured to operate a scavenger hunt in which participants are required to answer questions using information obtained from one or more Web sites visited in response to hints suggesting where such information may be located. Each preceding question must be successfully answered before a next question is presented. Generally, a correct answer requires verification that a respondent visited the Web site at which the information required in the answer is located. This, in turn, may require that the respondent reached the Web site at which the information required in the answer is located through an authorized path including at least one predetermined Web address. Such verification may be achieved by using referring uniform resource locator (URL) information regarding the at least one Web address as a security key to allow access to a location at which the respondent may enter the answer.

Abstract: Substances or agents which diminish the level of IL-6 or its activity in Kaposi's sarcoma-derived cells are useful agents in the treatment of Kaposi's sarcoma. In particular, substances which inhibit the expression of the gene encoding IL-6 or its receptor, or which interfere with the activity of these substances, are useful in the treatment of this condition. In particular, antibodies immunoreactive with these proteins, oligomers which interfere with the production of these materials, or substances which interfere with the activity of other proteins, DNAs or RNAs that regulate the production and activity of IL-6 are thus useful.
