20100289359 | Electropermanent Magnet-based Motors - An electropermanent magnet-based motor includes a stator having at least one electropermanent magnet, at least one coil around the electropermanent magnet configured to pass current pulses that affect the magnetization of the magnet, and a rotor that is movable with respect to the stator in response to changes in the magnetization of the electropermanent magnet. A wobble motor has a stator with a centrally-located core from which arms radiate outward, an electropermanent magnet and coil on each arm, and a rotor exterior to the stator such that the rotor can rotate around the stator arms. A rotary motor has a centrally-located rotor that rotates about its axis and a stator exterior to the rotor such that the rotor may rotate within the stator arms, the stator including an anteriorly-located stator core from which stator arms radiate inward toward the rotor, and an electropermanent magnet and coil on each stator arm. | 11-18-2010 |
20110289741 | Methods and apparatus for applying tension to a motion transmission element - In exemplary implementations of this invention, tension is applied to a motion transmission element with periodic features by causing that element to mesh with a device that has a pitch slightly greater than the pitch of the motion transmission element. The motion transmission element with periodic features may comprise, for example: (a) a belt with teeth, or (b) a chain. Further, the motion transmission element may comprise either an open or a closed loop. In exemplary implementations, the width of the teeth of the motion transmission element (along that element's long axis) is greater than the width of the teeth in the rack (along the rack's long axis). This allows room for the teeth of the rack to both fit and move within the gap between the teeth in the motion transmission element. This extra width of the element's teeth is not necessary if the element is sufficiently elastic. | 12-01-2011 |
20140085620 | 3D PRINTER WITH SELF-LEVELING PLATFORM - 3D printing systems and methods avoid build-compromising misalignments through the use of a self-leveling assembly that maintains a constant and typically fully parallel orientation between a build platform and the bottom surface of a resin tank. As a result, contact between the floor of the resin tank and the build platform surface may be uniformly flat and even, and perpendicular to the z-axis motion of the deposition source. | 03-27-2014 |
20140300017 | ADDITIVE FABRICATION SUPPORT STRUCTURES - Some aspects provide a method of generating a support structure for an object, the support structure and the object to be fabricated via one or more additive fabrication techniques, comprising identifying one or more regions of the object as one or more regions to which mechanical support is to be provided, identifying one or more support points within at least a first region of the one or more regions, and generating the support structure for the object, the support structure comprising one or more support tips coupled to the object at the one or more support points, the support tips being generated based at least in part on a direction normal to the surface of the object at the respective support point. | 10-09-2014 |
20140303942 | ADDITIVE FABRICATION SUPPORT STRUCTURES - Some aspects provide a method for evaluating a support structure associated with a three-dimensional object, the support structure and object to be fabricated via one or more additive fabrication techniques, comprising obtaining a representation of the support structure, wherein the support structure is configured to provide mechanical support to at least a first region of the object, calculating a supportedness value for the first region of the object, the supportedness value being indicative of a degree of support that the support structure provides to the first region, depicting the support structure and/or the object via a graphical user interface, and indicating the supportedness value for the first region of the object by coloring a portion of the graphical user interface using one or more colors, at least one of the one or more colors being based at least in part on the supportedness value. | 10-09-2014 |
