This article discusses the synthesis of a six-link transforming mechanism rocking machine.First, problem synthesizing four-link articulated-lever for reproducing verticalline was solved. For this purpose, rectilinear-guiding ofthe Evans type, which is hinged-lever with straight vertical line drawingpoint, considered. The task to implement constraint equation. geometricmeaning equation determine...

In this paper at first introduced constituent equations for piezoelectric and then by the help of this equations, internal energy of hinged-hinged piezoelectric multilayer beam was computed. Then by the principle of minimum potential energy and Rayleigh -Ritz method the bending curvature equation of hinged-hinged piezoelectric multilayer beam under concentrated moment, concentrated force, unifo...

This paper presents a general family of 3D hinged dissections for polypolyhedra, i.e., connected 3D solids formed by joining several rigid copies of the same polyhedron along identical faces. (Such joinings are possible only for reflectionally symmetric faces.) Each hinged dissection consists of a linear number of solid polyhedral pieces hinged along their edges to form a flexible closed chain ...

We have investigated magnetic actuation of hinged, surface micromachined structures. Electroplated magnetic material (Permalloy) is integrated with two types of hinged microstructures and the magnetic actuation process has been experimentally characterized. Under a given external magnetic field, the angular displacement of a hinged structure is determined by the volume of the magnetic material ...

We have developed a new magnetic actuation process for assembling three-dimensional MEMS devices using hinged, surface micromachined structures. Electroplated magnetic material (Permalloy) is integrated with two types of hinged microstructures and the magnetic actuation process has been experimentally characterized. Under a given external magnetic field, the angular displacement of a hinged str...

We prove that two polygons A and B have a reversible hinged dissection (a chain hinged dissection that reverses inside and outside boundaries when folding between A and B) if and only if A and B are two non-crossing nets of a common polyhedron. Furthermore, monotone hinged dissections (where all hinges rotate in the same direction when changing from A to B) correspond exactly to non-crossing ne...

Enabled by advances in both integrated circuit technology and micro electrome-chanical systems (MEMS), the continuing miniaturization and integration of electronics, sensors, actuators and mechanisms will make it feasible to create insect-sized autonomous microrobots. We propose to create a class of autonomous crawling microrobots the size on the order of 1cm 3 and equipped with a power source,...

OBJECTIVE To investigate the effectiveness of the hinged ankle-foot orthosis (AFO) on sit-to-stand (STS) transfers in children with spastic cerebral palsy. DESIGN Before-after trial. SETTING University-affiliated hospital. PARTICIPANTS Nineteen spastic diplegic children (age range, 2-6 y). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The transitional movement of STS was tested ...

Exposures to diacetyl, a primary ingredient of butter flavoring, have been shown to cause respiratory disease among workers who mix flavorings. This study focused on evaluating ventilation controls designed to reduce emissions from the flavor mixing tanks, the major source of diacetyl in the plants. Five exhaust hood configurations were evaluated in the laboratory: standard hinged lid-opened, s...
