    摘要: A towable, furrow opening seed planting assembly includes a mobile frame and a planting unit, the planting unit including a ground engaging opener, a seed depositing apparatus and a press wheel for covering the deposited seed with soil. A variety of different press wheels may be substituted through the use of adapters removably mounted on a universal press wheel arm whereby press wheels having different widths may be maintained in proper alignment with the furrow created by the opener for ensuring proper soil coverage and contact with the deposited seed.

    摘要: A seed firming wheel assembly is supported in close-coupled relationship with the rear portion of the paired discs of an opener to gently press deposited seeds down into the bottom of a V-shaped trench formed by the discs. The mounting arm of the assembly is configured in a manner to minimize the accumulation of mud and trash residue, while the wheel itself may take the form of a solid, circular block of ultra-high-molecular-weight polyethylene with slick sides to reduce soil adherence or a spoked, molded plastic wheel having open spaces between the spokes to permit soil pass-through.

    摘要: The front folding machine has a main fore-and-aft carrier frame provided with transport wheels that may be hydraulically actuated to raise and lower the frame simultaneously with the actuation of gauge wheels on a pair of transverse drill units connected to the rear of the carrier frame, thereby causing the trash cutters and openers which are carried by the drill units to raise out of the ground while the gauge wheels and transport wheels remain in ground engagement. Before folding the drill units forwardly into transport positions extending parallel to the path of travel, the drill units are raised by hydraulically operated tool bars into elevated positions in which the gauge wheels of the units are entirely off the ground and the residue cutters are high enough to clear the transport wheels of the carrier frame as the drill units are folded into the transport position. The tool bars which provide elevation for folding purposes are also provided with flotation pivots by which the drill units are connected to the tool bars so that the individual units can rock laterally about separate fore-and-aft pivots when the machine is unfolded and the gauge wheels encounter changes in terrain during field operations. Flotation limit means associated with the drill units prevent excessive rocking movement during terrain changes and also assist in the control of the drill units during raising and lowering between field and transport positions.

    摘要: A method in a mobile device for use in receiving updates of network-maintained map data sets is described. The mobile device receives, through a wireless network, map data for rendering a map. The map data has a plurality of layers, where each of the plurality of layers includes a version number and a plurality of data entries associated therewith. Each of the plurality of data entries indicates a plurality of data points for rendering one or more artifacts or labels within an area of interest of the map. The mobile device stores the map data, and displays the area of interest from the plurality of layers of the stored map data. The mobile device then receives, through the wireless network, an indication of an alternative version of one of the layers of the stored map data. When the version number of the alternative version is greater than the version number of the stored version, the mobile device causes one or more requests for the alternative version of said layer for the area of interest to be sent through the wireless network. The mobile device also receives the alternative version of said layer for the area of interest through the wireless network in response to the one or more requests. The mobile device also then causes the map of the area of interest to be rendered in the display in accordance with the combined plurality of layers of the stored map data, but with use of the alternative version of said layer.

    摘要: This is directed to controlling the output of audio based on the mode of an electronic device. In particular, this is directed to an electronic device having a sound mode, silent mode, and mute mode controlling the output of audio along different audio output routes. In the sound mode, all audio can be output, while only registered or authorized audio can be output in the silent mode. In the mute mode, no audio can be output. The sound and silent modes can be enabled using an interface of the device (e.g., a switch having two possible states), while the mute mode can be enabled using an accessory coupled to the device. To disengage the mute mode, a user can provide a corresponding instruction using the accessory, or providing an instruction on the device related to volume control. For example, a user can change the device volume using an on-device interface, or toggle a sound/silent switch to a sound mode.

    摘要: A downhole valve has a closure device (e.g., one or more flappers) for closing off the valve. A no-go actuation mechanism protects the flappers from damage. When the flappers are closed, the mechanism prevents a tool from passing into the valve and causing damage to the flappers. Yet, the mechanism may open the valve's flappers when the tool string is forced into the valve. When the valve has successfully opened, then the mechanism moves out of the way of the toolstring so it can pass through the valve. For the mechanically operated valves, operators use a shifting profile in the valve only in the upward direction to return the valve to the closed position. For hydraulic actuated valves, hydraulic pressure may be used or exhausted, depending on the design, to allow the flappers to go closed. Once the flappers have closed, the no-go mechanism is once again realized.
