  • Patent number: 9589432
    Abstract: A haptic peripheral including a magnetic actuator coupled to a user input element for providing haptic effects to the user input element. The magnetic actuator includes at least two opposing programmable magnets, a first programmable magnet and a second programmable magnet, with pre-programmed patterns to control the motion of the user input element. Each programmable magnet has a pre-programmed pattern of magnetic elements. The pre-programmed patterns of the magnetic elements interact with each other to cause haptic effects. In order to vary to haptic effects output by the magnetic actuator, the second programmable magnet is spun, rotated, or otherwise moved to change the orientation or position of the pre-programmed pattern. The re-oriented pattern of the second programmable magnet changes the interaction between the first and second programmable magnets and thereby results in different haptic effects being output to the user input device.

  • Patent number: 8394310
    Abstract: An inflatable compaction tool for consolidating a composite material inside a faceted hollow or tubular mold for a composite part is made from an elastic material. The compaction tool includes relatively flat wall segments conjoined by corner segments that define a sealed chamber. The wall segments curve away from the mold surface toward the midpoint of each wall segment, so that as a pressurized fluid is introduced into the compaction tool, a component of the force exerted on the tool interior surface is transmitted through the wall segments toward the corner segments. Thus, during initial inflation, the corner segments are forced toward the corner regions of the mold before the wall segments contact the composite material, firmly compressing the composite material into the corner regions of the mold before the friction of the wall segments against the composite material inhibits expansion of the corner segments into the mold corner regions.

  • Patent number: 8372330
    Abstract: A solidification substrate assembly for making a three-dimensional object from a solidifiable material includes a solidification substrate assembly. In certain examples, the solidifiable material solidifies in contact with the solidification substrate, and the tilting of the substrate and/or or the use of a peeling member facilitates separation of the substrate from the solidified material. In other examples, the solidification substrate assembly includes a film that is adjacent to a rigid or semi-rigid layer. The solidifiable material solidifies in contact with the film, and a peeling member peels the film away from the solidified material. Intelligent solidification substrate assemblies are also described in which a force sensor determines when to expose the solidifiable material to solidification energy and/or whether to use a peeling member to separate the solidification substrate from a solidified objection section.

  • Patent number: 8371838
    Abstract: The present invention relates to a method and a device for placing at least one material layer onto a relief mold for producing a composite material. Thereby, an elastically-reversibly deformable body with a surface relief that is designed to correspond to the relief mold is pressed against the material layer, as a result of which the surface of said body is deformed, and the material layer can be picked up. As a result of its elastically-reversible characteristics the body subsequently deforms back to its initial state so that the material layer can easily be placed onto the relief mold.

  • Patent number: 8337740
    Abstract: A complex-shaped, three-dimensional fiber reinforced composite structure may be formed by using counteracting pressures applied to a structural lay-up of wetted fibers. The wetted fibers are arranged on pressurizable members and may be configured to include internal structural features, such as shear webs. A reinforcement stiffener may be located adjacent to at least one of the pressurizable members and the wetted fibers that form the internal structural feature. The reinforcement stiffener includes a modulus of elasticity that is substantially higher than a modulus of elasticity of the resin used to wet the fibers. In one embodiment, the reinforcement stiffener may be received in a pocket of one of the pressurizable members and may include a releasing agent that permits removal of the stiffener after the composite structure has been pressurized and cured.

  • Publication number: 20120302670
    Abstract: A mold assembly or system includes a moldbase that holds mold inserts and has embedded fluid lines to facilitate cooling during part formation. Mold inserts combine to form mold cavities that receive carbon fiber and resin components to form a carbon composite based part. A permanent release coating along a mold component surface that contacts the carbon fiber and resin components facilitates the release of the finished part from the mold component. Guide pins and guide pin receiving holes facilitate accurate alignment of mold components. Ejector pins within respective ejector pin shafts help eject a finished part from a respective mold component. An ejector pin shaft cover transfers force from an ejector pin to eject a finished part and also prevents substantial passage of resin into the ejector pin shaft. A fluid actuated ejection system provides fluid based mechanical forces to the ejector pins to facilitate finished part ejection.

  • Publication number: 20120256348
    Abstract: A material forming apparatus and method for shaping a material to a forming tool having complex contours. The material forming apparatus may comprise a bladder sealed to a support structure, cooperatively forming a hollow space therebetween into which air or another gas may be pumped to inflate the bladder. The forming tool may comprise a protrusion of any shape to which the material may conform. The material may be placed between the bladder and the protrusion and the support structure may be actuated toward the forming tool. As the support structure progresses toward the forming tool, an area of material pressed against the protrusion by the bladder increases in an outward direction. A pressure regulator may regulate an amount of pressure applied to the material by the bladder as the bladder presses the material against the forming tool.
