Abstract: A method for adaptively teaching content to a user comprises providing a plurality of teaching topics. The method includes sequentially associating a lead problem and a plurality of secondary problems with each of the plurality of teaching topics. Each of the lead problems and the plurality of secondary problems is an open-ended puzzle having a range of solutions and a difficulty rank. The range of solutions for each of the lead problems and the plurality of secondary problems has an optimal solution and a plurality of secondary solutions. A teaching topic is selected and a corresponding lead problem is presented to a user. User provides answer data via a physical input device having enmeshed gears. The user is provided another secondary problem in the selected teaching topic if the answer data matches one of the secondary solutions. The user is provided another lead problem if the answer data matches the optimal solution.

Abstract: An integral vehicle jack assembly is provided for facilitating raising of the ground engaging members of a vehicle off of a supporting surface. The assembly includes a vehicle having a plurality of ground engaging members. A plurality of telescopic supports is coupled to the vehicle. Each support is movable between a deployed position and a retracted position. The deployed position is configured for raising the vehicle such that the ground engaging members are positioned in spaced relationship to a support surface. A control is operationally coupled to the supports for selectively extending and retracting the supports.

Abstract: A visual aim indicator shows players the position of a selected one of a set of aim points during a video game. Each of the set of aim points has a predetermined position. The predetermined positions are within a target region, so that the visual aim indicator shows players the likely destination of their aim. Each aim point is associated with a range of control input values, so that players do not need to provide a precise control input value and can quickly select one of the set of aim points. The sizes of the ranges of control input values associated with the aim points can vary so that a player's aim inputs can be biased towards or away from specific aim points. The visual aim indicator is displayed intermittently during an aiming mode of operation and removed from view when the player completes the aiming mode of operation.

Abstract: Methods and articles are provided for frangible slugs. A method of manufacturing a frangible slug includes heating substantially spherical metallic powdered particles, where substantially all of the powdered particles have diameters larger than 125 microns and smaller than 250 microns, to form heated powdered particles. The method includes heating a microcrystalline wax to form a melted wax. The method also includes combining the heated powdered particles with the melted wax to form a liquid mixture. The method further includes filling a payload cavity of a slug container with the liquid mixture to form a liquid mixture payload, where the slug container is configured to retain a solidified frangible payload as the frangible slug until impact with a solid object.
