20130136295 | Loudspeaker Based on "The Principle of The Center Of Percussion." - A transducer of electrical oscillations to mechanical oscillations, mainly a loudspeaker having in general an elongated oscillating member attached by joints to a surrounding structure in areas of points or lines of specific dynamic balance, like one end, center of mass, center of percussion about a certain point or axis of rotation. At least one electromagnetic actuator is mounted in the area of these balancing points or lines. The use of the principle of the center of percussion is allowing for higher loudspeaker performance. | 05-30-2013 |

20090055136 | Geometric Singularity Detection - A system and method for geometric singularity is presented. In one aspect, the system and method are employed for detecting and quantifying envelope singularities of one or more solid shapes in relative movement. In an implementation, a solid shape having a motion is defined. A set of points in a space in which the motion of the solid shape occurs are sampled. For each point in the set of points, the following values are determined: an inverted motion of the motion; one or more inverted trajectories that correspond to points of the space associated with the inverted motion; one or more intersections between the inverted trajectories and a boundary defined by the motion of the solid shape; and one or more tangencies between the inverted trajectories and the boundary. Each point in the set of points is then classified as a function of values of the intersections and tangencies, each classification being one of a set of classifications including an interior fold point, a fold boundary point, a regular point, a sweep boundary point, or a point exterior to the set swept by the solid shape during the motion. | 02-26-2009 |
