Devices, systems, and methods employ an implant that is sized and configured to attach to the annulus of a dysfunctional heart valve annulus. In use, the implant extends across the major axis of the annulus above and/or along the valve annulus. The implant reshapes the major axis dimension and/or other surrounding anatomic structures. The implant restores to the heart valve annulus and leaflets a more functional anatomic shape and tension. The more functional anatomic shape and tension are conducive to coaptation of the leaflets, which, in turn, reduces retrograde flow or regurgitation. The implant improves function to the valve, without surgically cinching, resecting, and/or fixing in position large portions of a dilated annulus, or without the surgical fixation of ring-like structures.

A three-dimensional shape measuring apparatus includes a line laser light source (1) and an image capturing device (2). A three-dimensional shape measuring method and apparatus is characterized by irradiating a line laser beam to an object (3) to be measured from a laser projecting device, imaging points (6) irradiated with the laser beam by the image capturing device (2, detecting points on taken images as intersections (8), each of the points being detected from the taken images and being detected as a common point where line laser beams pass, deriving equations including the positions of the laser planes and the three-dimensional positions of the intersections as unknowns based on the detected intersections, determining the three-dimensional positions of the intersections and the positions of the laser planes by solving the derived equations as simultaneous equations, calculating by triangulation the three-dimensional positions of the points irradiated with the laser beams other than the intersections by using the positions of laser planes, and obtaining the three-dimensional shape of the object by repeating the series of processes.

Disclosed are methods for determining the largest subset of points that remains within a set of points S (i.e., shape S) when S is subjected to a motion M. These methods, which are generally designated herein as unsweep (or formalistically unsweep(S,M)), can be implemented (preferably by computer) for a variety of practical purposes, for example mechanical parts design. In this instance, simply by knowing the motion to be experienced by a part and the envelope wherein the part must fit during motion, unsweep can define the largest part that fits within the envelope according to the given motion. While direct part shape output is obtained, no part shape needs to be proposed beforehand, and thus the design process is no longer an iterative process of proposing shapes and correcting them in the case of interference. Further, unsweep is related to the known sweep function and can be used to obtain sweeps as well as unsweeps.

A swing rotary fitness apparatus is described. A swing base is axially disposed at a center of a bracket having a pair of handles. A pound-force adjuster is disposed between the swing base and the bracket, and elastic elements for restoration are disposed between the swing base and the bracket. In addition, a rotatable seat is disposed on the swing base. When a user rides on the seat, the user exerts a force by lumbar muscles, so as to generate a circumferential motion of synchronous swing and rotation, which increases amplitude of twisting lumbar muscles greatly and thus improves an effect of exercising the waist.

An improved electric motor design wherein the interior surface of the stator has a plurality of corrugations intersected by annular grooves formed therein and a corresponding number of rotor disks having permanent magnets secured to their outer surface, the permanent magnets being positioned to rotate within the grooves. The magnets alternate in polarity about each disk as well as being offset about the circumference from disk to disk so that one disk set will align with the pole face created by the intersection of the corrugations and the adjacent annular grooves and the other disk set will be offset from the corrugations and pole faces. Alternately energizing coils positioned within a plurality of notches formed in the outer surface of the stator with alternating current causes the magnets and their associated disks to reposition themselves in a manner that causes the motor shaft to rotate as well as shaping the core flux field for more efficient use, thereby increasing motor torque.

A packet shaping device for the purpose of shaping a packet in which burst has grown in a router to an original packet without the burst growth is disclosed. The packet shaping device monitors an arrival time TA of each packet on which a pass time TP is recorded when the packet passes a prescribed pass point and calculates a delay time TD which is a time difference between the pass time TP and the arrival time TA. Then, the packet shaping device obtains a maximum delay time TD_max among the delay times, and delays and sends all the arrived packets in such that the delay time of all the arrived packets is equivalent to the maximum delay time.

Coordinate transformation parameters are adopted at the time of synthetically combining partial measurement data so as to eliminate the setting error that can get in when a workpiece is set in position on a measuring machine. Then, a shape parameter is adopted to estimate the approximate error shape of the entire workpiece and the approximate error shape is removed from the measurement data. As a result, the residuals are reduced if the measurement data are those of three-dimensional sequences of points. Differences are small when small residuals are compared so that the mismatch is reduced. According to the present invention, the entire measurement data can be synthetically combined without using the conventional concept of overlap.

The invention relates to a novel control method for improving lithium ion soft-package laminated battery diaphragm fold. The problem that the battery performance is influenced due to the fold of the soft-package laminated lithium ion battery diaphragm is solved. The control method comprises the following steps: laying down a battery after liquid injection, thereby ensuring that the electrolyte sufficiently infiltrates a pole piece; and then performing rolling on the lay-down battery, and controlling the pressure and speed of the rolling in the rolling process; pre-charging the battery after the rolling is ended; and performing secondary rolling on the completely pre-charged battery, further shaping the diaphragm, and releasing the gas to finish the secondary package. The contacting interface between a positive/negative pole piece and the diaphragm is better by comparing the lithium ion soft-package laminated battery prepared based on the control method with the battery without performing the rolling shaping, the dead lithium existing in the fold area caused by the diaphragm fold is avoided, thus the capacity of the positive/negative material is sufficiently played, and the batteryperformance is improved.
