Abstract: A radial compression mechanism utilizes a string wrapped around a plurality of compression dies to move the dies inward and close a central cylindrical cavity defined by the working surfaces of the dies. The string may be coupled to a string tension mechanism that enables a user to applied a desired tension to the string and thereby compress an article within the central cylindrical cavity. The compression dies may be coupled to a base and move along die-guiding slots from an open position to a closed position. A spring may be configured to force the compression dies open and provide some back-tension to the string. The string may extend around a pully on an opposing side of the compression mechanism and both ends of the string may be coupled to the string tension mechanism.

Abstract: Systems and methods for generating composite depth images are disclosed. Exemplary implementations may: capture, by a depth sensor, a set of depth images over a capture period of time; generate, by an inertial sensor, inertial signals that convey values of one or more inertial parameters characterizing motion of the depth sensor during the capture period of time; select a target capture position based on one or more of the capture positions of the set of depth images; generate, using the values of the one or more inertial parameters during the capture period of time, re-projected depth images; and generate a composite depth image by combining multiple depth images, such multiple depth images including a first re-projected depth image and a second re-projected depth image.

Abstract: A modular filtration platform having at least one manifold head and at least one respective filter cartridge assembly. Each manifold head is connected to one another to establish a water flow in a series or parallel manner. Each filter cartridge assembly is releasably secured from rotation relative to the manifold head by a locking mechanism. An aperture on the filter cartridge assembly annular collar mates with a protruding resilient extension on either the manifold head or support bracket. Alternatively, an aperture on the filter cartridge assembly annular collar and an aperture on the manifold head annular collar mate with a protruding member from a locking ring extending through both apertures. An integrated sensor package may be integrated with the system for true managed water visible/audible indications and Wi-Fi interface to facilitate virtually instantaneous response times for filtration needs.

Abstract: Automatic propagation of real-world parent seismic images to efficiently generate a collection of realistic synthetic child training images to train a model for accurate automatic seismic interpretation. A 3D structural model in a present-day geological space (e.g., GB) depicting subsurface locations of particles (e.g., in region B) may be transformed by a 3D coordinate space transformation (e.g., uvtB) to a depositional space (e.g., G*B) depicting past depositional locations of those particles (e.g., corresponding depositional region B). A real-world parent image depicting subsurface locations of particles (e.g., in region A) may be transformed, via a forward transformation (e.g., uvtA), to a depositional seismic image in the depositional space of the three-dimensional structural model (e.g., G*A=G*B). A reverse transformation (e.g., uutB?1) may transform the depositional seismic image from the depositional space into synthetic child training images in the present-day geological space (e.g.

Abstract: Techniques are provided for pattern-aware prefetching using a parallel log-structured file system.

Abstract: A dual-factor PIN based authentication system and method uses a cryptogram provided by a contactless card associated with the client in association with a PIN stored by the contactless card to authenticate the client. In some embodiments, cryptogram authentication may be preconditioned upon a PIN match determination by the contactless card. In other embodiments, the cryptogram may be formed at least in part using the personal identification number (PIN) stored on the contactless card encoded using a dynamic key stored by the contactless card and uniquely associated with the client. Authentication may be achieved by comparing the cryptogram formed using the PIN against an expected cryptogram generated an expected PIN and an expected dynamic key.

Abstract: An inventory system for storing and locating goods in a storage area. Ordered goods are placed in bag units at a central filling center. The filled bag units are shipped to local storage areas where they are placed onto rails in a storage structure. The rails include an imaging sensor at each bag receiving location defined on the rails for obtaining a bag identifier that is affixed with the bag unit. The bag identifier and the rail address for each bag unit is stored on a local computer database. When a user wants to pick up stored goods, the user inputs the identification or order information for the goods and the computer will search the inventory to locate the goods in a specific stored bag unit. The rail adjacent the bag unit will be illuminated to facilitate locating the goods.

Abstract: A method includes identifying, for a specified vehicle, a competitive set of other vehicles based on input from a user. The method also includes receiving from the user one or more parameters to be used in pricing the specified vehicle. The method further includes identifying a recommended price for the specified vehicle using the competitive set and the one or more parameters. The one or more parameters could include a selection or definition of multiple pricing formulas to be used to identify the recommended price. Different pricing formulas can be associated with different lengths of time that the specified vehicle is available. A first of the pricing formulas can be used to identify a first recommended price for the specified vehicle and, after a specified amount of time has elapsed, a second of the pricing formulas can be used to identify a lower second recommended price for the specified vehicle.

The one or more computing devices may display the selected panoramic image and the first panoramic image and align the selected panoramic image with the first panoramic image such that the selected panoramic image is oriented in the same direction as the first panoramic image. The one or more computing devices may connect the selected panoramic image with the first panoramic image.

Abstract: A media server is hosted in a service provider's network so that media content can be stored from or rendered to a private network such as a Digital Living Network Alliance network. Media content may be stored by accessing the media server or by downloading the media content to the media server. Support of set top boxes interacting with voice-on-demand (VOD) controllers and computers interacting with IP-based video content servers are integrated through the media server. Consequently, VOD assets can be played on IP-based devices and IP-based content can be played on set top boxes. A gateway function converts IP-based content to a VOD asset, and renders the VOD asset to a set top box while mapping digital rights management information for the VOD asset. Conversely, the gateway function may convert a VOD asset to IP-based content that can be played on an IP-based device.

Abstract: A non-occluding drug-coated balloon catheter device for use in a blood vessel transporting blood comprises a catheter shaft including a guidewire lumen, a fluid lumen and a connector port. A balloon is mounted on the catheter shaft and includes an outer envelope surrounding the guidewire lumen in fluid communication with the fluid lumen; a drug coating applied on the exterior surface of the outer envelope; and at least one bypass lumen forming a passage extending from the proximal end of the outer envelope to the distal end of the outer envelope. When the balloon is positioned in a blood vessel and inflated, the exterior surface of the outer envelope presses the drug coating against the blood vessel and the bypass lumen is open between the distal end of the outer envelope and the proximal end of the outer envelope such that blood transport continues through the bypass lumen.
