Abstract: This disclosure describes systems, methods, and devices related to robotic control for tool sharpening. The device may determine a first location associated with a first cutting tool of the one or more cutting tools relative to the first container. The device may grip the first cutting tool based on the first location of the first cutting tool relative to the first container. The device may move the robotic device to one more scanning sensors. The device may collect three dimensional data. The device may extract a profile of the first cutting tool. The device may determine a top edge and a bottom edge based on the profile. The device may determine a tip of the first cutting tool. The device may generate a sharpening path based on the tip and the profile of the first cutting tool.

Abstract: Disclosed herein are systems and techniques for producing complex components using a reinforced thermoplastic material. The complex components can include contoured or curved outer surfaces, and in some cases define a cavity. In certain examples, one or more thermoplastic materials are arranged to form a wheel component, such as that adapted to define a rim of the bicycle. Thermal bonding can be used to join multiple reinforced thermoplastic materials to one another in order to form a cavity of the wheel component or other complex shape. In certain examples, a portion of a tooling assembly can be pressurized to maintain a shape of the cavity during thermal bonding and cooling. This can remove the need for a sacrificial bladder or other structure that would maintain the shape of the cavity, allowing for a seamless final component, optionally absent indicia of bladder exit or other seams.

Abstract: Context menus are described. In one or more implementations, an option is displayed in a user interface by a computing device, the option selectable to cause a representation of an object to be added to a context menu. In response to selection of the option, the context menu is configured by the computing device to include the representation of the object such that the representation of the object is selectable to launch the object by the computing device.

Abstract: A composite ammunition magazine comprises a box with a follower slidably disposed in the box and a spring disposed between a bottom of the box and the follower and biasing the follower towards an open top. A pair of opposite lips extends from proximal ends at opposite sides of the open top in an arc to distal free ends over the open top of the box. The box and the pair of lips comprise a composite material comprising fibers in a resin matrix with the sides of the box comprising hoop fibers oriented at 0 degrees and axial fibers oriented at 90 degrees, and the pair of lips comprising lateral fibers oriented at 0 degrees and arc fibers extending in an arc and oriented at 90 degrees with respect to the lateral fibers. The pair of lips comprises more arc fibers than the axial fibers in the box.

Abstract: A trigger assembly for use with a firearm has a hook carried by and pivotal with a selector to engage an aft tab of a hammer in the safe position of the selector.

Abstract: A rifle barrel for a gas-operated rifle includes a metallic liner with a longitudinal bore and a transverse gas port through the liner to the bore intermediate along a length of the liner. A thermally conductive sleeve circumscribes the liner substantially along the length of the liner. A composite wrap circumscribes the sleeve substantially along a length of the sleeve. The composite wrap is separated from the gas port.

Abstract: An integral hand guard and accessory rail has an elongated shell with a shell wall adapted to be spaced-apart from and circumscribing a barrel of a firearm. The shell has a portion adapted to be griped by a user and defining a hand guard. The shell wall has another portion protruding radially away from the barrel defining an elongated rail, the rail having a cross-sectional shape orthogonal to the axis with a narrower neck a wider head coupled to the shell by the neck.

Abstract: Methods and apparatuses are disclosed for power conversion for fuzes and other electrical power consumers. A current monitor coupled to a power source signal generates a source current indicator. A controller generates a control signal responsive to the source current indicator. A filter well is coupled to the power source signal. An inductive switch circuit switchably grounds a rectified inductive load coupled to an output side of the filter well in response to the control signal, developing a pulsed power signal. A resonance rectifier presents substantially lossless resistive impedance for the pulsed power signal and rectifies the pulsed power signal to charge a charge storage device and generate a power output signal. The filter well, the inductive switch circuit, and the controller maintain the source current indicator within a predetermined current range by filtering the pulsed power signal and adjusting the control signal's frequency responsive to the source current indicator.

Abstract: According to one embodiment, a bow includes a handle portion and a bowstring. Compression members including primary compression elements and secondary compression elements are positioned on the ends of the handle portion. The compression elements are arcuate in shape and joined at the ends. As the bowstring is drawn, the compression members are compressed and energy is stored therein. The bow can include limbs that do not significantly deform or store energy as the bow is drawn. Upon release of the bowstring, the stored energy is rapidly returned to the bowstring.

Abstract: Embodiments of the invention provide a method, system, and media for intelligently presenting representations of files. The method can include determining a set of files for which information about them is to be rendered in a window of a graphical user interface even when not all of the files are the same type, conditioning a format of each representation based on a type of each file, selecting for each representation a set of file properties to be presented (the selection being based on the type of each file), and presenting the set of representations consistent with the formats and with appropriate file properties.
