Abstract: To provide geographic data to client devices for offline use, a system receives, from a client device via a communication network, an indication of a current location of the client device. The system identifies geographic data to be provided to the client device to define an area of offline coverage, which includes determining boundaries of the area of offline coverage based on an amount of geographic data the client device is expected to receive prior to reaching certain points within the area of offline coverage. The system provides the geographic data to the client device.

Abstract: Design tools and methods of use for designing, ordering, and providing manufacturing and installation instructions for waveguide system networks include a system design tool including a location selection module to determine a selected location, a satellite imagery component to provide an image based on the selected location, an overlay module to overlay a design on the image, and a customization module to customize the design. The system design tool includes one or more design modules to at least one of automatically output and build via user input one or more design options based on the image, and a design customization module to select the design from the one or more design options. The system design tool includes a positioning module to set a pair of connectivity points such that a cable length may be automatically calculated based on a calculated distance between the pair of connectivity points.

Abstract: Geographic data corresponding to a certain geographic area of offline coverage is stored in a memory of a computing device. An indication of a geographic boundary delimiting a region smaller than, and contained within, the geographic area is obtained. A current location of the computing device relative to the geographic boundary is determined and, in response to determining that the current location is outside the region, additional geographic data is retrieved via a wireless communication network to expand the geographic area of offline coverage. At least some of the geographic data corresponding to the expanded geographic area is provided via a user interface of the computing device when the computing device is offline.

Abstract: Systems and methods directed to a digital rangefinder camera are described. The digital rangefinder camera may include a viewfinder assembly configured to receive a first optical image from a first optical path and a focus ring movement detection assembly configured to detect an amount of movement associated with a focus ring of a lens attached to the digital rangefinder camera. A processing device may be configured to provide a movement signal indicative of the amount of movement associated with the focus ring to an actuator coupled to an optical element, where the actuator moves the optical element and displaces a second optical image from a second optical path directed toward an optical component in the viewfinder assembly. The optical component in the viewfinder assembly is configured to project the first optical image and the second optical image toward a single common viewing position when the first optical image and the second optical image coincide.

Abstract: Systems and methods provide a route and turn-by-turn directions based on estimates of current and future traffic along the route. A client device may request turn-by-turn directions between an initial and a final location. A server may identify a plurality of routes between the locations. Each route of the plurality of routes may be divided into route segments. For each route segment of a particular route, the server may estimate a travel time. The travel time may be based on estimated vehicle volume data generated from information received from other vehicles. The server may estimate a total travel time for the particular route. The server may repeat this estimate for each of the plurality of routes between the locations and select the route with the lowest estimated travel time. Based on the selected route, the server may generate turn-by-turn directions and transmit the directions to the client device for display.

Abstract: A distributed, web-services based storage system. A system may include a web services interface configured to receive, according to a web services protocol, a given client request for access to a given data object, the request including a key value corresponding to the object. The system may also include storage nodes configured to store replicas of the objects, where each replica is accessible via a respective unique locator value, and a keymap instance configured to store a respective keymap entry for each object. For the given object, the respective keymap entry includes the key value and each locator value corresponding to replicas of the object. A coordinator may receive the given client request from the web services interface, responsively access the keymap instance to identify locator values corresponding to the key value and, for a particular locator value, retrieve a corresponding replica from a corresponding storage node.

Abstract: An injection molding machine having a first mold portion and a second mold portion. The second mold portion being movable relative to the first mold portion and together defining a mold cavity. The injection molding machine includes a fluid path extending through the first mold portion. The fluid path has an inlet and a radially continuous, downwardly-extending, circumferential outlet in fluid communication with the mold cavity. The injection molding machine further having a valve ring movably coupled in the first mold portion. The valve ring includes a downwardly extending rim portion substantially disposed within the fluid path. The valve ring is positionable in a closed position where the rim portion engages the circumferential outlet to obstruct flow of the molding material from the fluid path to the mold cavity and an opened position where the rim portion is spaced apart from the circumferential outlet to permit flow of the molding material from the fluid path to the mold cavity.
