We describe a method to store and retrieve design cases of four-bar linkages. The method abstracts relevant features from the planar curve that characterizes each linkage design, and records these features at several levels of abstraction. This allows to use a fast multi-level retrieval procedure, that successively eliminates inappropriate cases at each level. The retrieval incorporates toleran...

Perhaps the most common configuration for planar manipulandums used in motor control studies is the serial five -bar linkage, but this design suffers from strongly directional inertia and force production characteristics. An alternative parallel-link design whose properties are less direction-sensitive across the workspace has been used in wrist-motion studies, but has never been scaled up for ...

Kcnk4–1.7 6 1.0–Adra2c. Additional comments: We have compared our interspecific map of chromosome 5 with a composite mouse linkage map that reports the map locations of many uncloned mouse mutations (provided from the Mouse Genome Database, a computerized database maintained at The Jackson Laboratory, Bar Harbor, ME). Kcnk4 mapped in a region of the composite map that lacks mouse mutations with...

Abstract Inspired by the jumping action of frogs, the mechanical structure of four-legs jumping robot is given particularly. This robot is used for the rough terrains or wetland environmental exploration. The four identical legs are mainly composed of a six-bar spring/linkage mechanism integrated with two springs. The D-H parameters, the forward kinematics equation and mechanics analysis on one...

mechanism, elastic displacement Abstract—This paper has as main purpose to identify the dynamic components of the matrices in the motion equation, combining the motion of rigid body with the one of elastic body. The finite element modeling requires the identification of a proper procedure in order to establish accurate boundary conditions which assure continuous motion in the nodes. Finally, an...

A large number of independent and interacting factors affect seating comfort such as seat shape, stability, lumbar support and seat height. Although many subjective comfort studies have been conducted, few of them considered seating comfort from its subassembly level. This paper analyzed the automotive seat cushion designed with geared four-bar linkage for the seat height adjustment. The operat...

INTRODUCTION Individual-level data on all prescription drugs sold in Danish community pharmacies has since 1994 been recorded in the Register of Medicinal Products Statistics of the Danish Medicines Agency. CONTENT The register subset, termed the Danish National Prescription Registry (DNPR), contains information on dispensed prescriptions, including variables at the level of the drug user, th...
