AbstractMany states and nations bloat their constitutions with procedural and policy details that other polities leave to statutory or regulatory discretion. American state constitutions vary in length from under 9,000 to almost 400,000 words. Long-lived constitutions can provoke fears that the dead hand of the past may reach into the present; lengthy ...

Development of gripping mechanism for a prosthetic hand
International Journal of Computer Aided Engineering and Technology, 2014Prosthetic hand is an artificial device which replaces human hand lost due to trauma or congenital. Prosthetic hand should be simple for a person with amputations to use and should contribute to their performance in grasping task. The prosthetic hands usually consist of a finger like and thumb like member to grip an object.

Optimal Grip Points with Human Hand
International Journal of Humanoid Robotics, 2016The aim of this work was to determine how an object of given shape should be grasped to maximize the grasping capacity of the human hand. To do that the model searches the optimal grip points on the object with the aim of maximizing the weight of the object lifted without slipping.

Reliability of a hand gripping endurance test
Ergonomics, 1997The aim of this study was to assess the reproducibility of a new endurance test for hand grip movements. On six occasions separated by at least 3 days, 30 healthy subjects performed six maximal endurance tests in two different positions with a hand grip tool attached to an isokinetic dynamometer. The test consisted of repeated maximal grip movements (1-

Humans and robots: Hand in grip
Acta Astronautica, 2005As we move boldly forward into the 21st century, there has rarely been a more exciting time in which to contemplate the future of space exploration. The President of the United States has made a new and ambitious commitment to exploration of the solar system and beyond.

Gripping Force Modeling of a Binding Hand
2019 2nd IEEE International Conference on Soft Robotics (RoboSoft), 2019Lunch boxes (boxed meals) are popular in Japan, as they are in many locations. Japanese lunch boxes contain foods with a wide variety of shapes, and many are flexible or soft. The current generation of robotic hands often struggles to grasp objects like this. This research aims to develop a robotic hand based on the use of a flexible thread that grasps

Cardiovascular Responses to Isometric Hand grip vs. Relaxed Hand Grip in Sustained Cycling Efforts
Journal of Strength and Conditioning Research, 2012Peripheral isometric contractions may lead to enhanced performance. Previous research using hand grip protocols indicates increased stabilization and peak power outputs. Research is lacking with the grip vs. no-grip protocol during sustained efforts.

Precision grips, hand morphology, and tools
American Journal of Physical Anthropology, 1997This study asks whether there are discernable links between precision gripping, tool behaviors, and hand morphology in modern hominoids, which may guide functional interpretation of early hominid hand morphology. Findings from a three-pronged investigation answer this question in the affirmative, as follows: (1) Experimental manufacture of early ...

Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1995
An efficient measurement and evaluation system for hand tool tasks can provide a practical solution to the problem of designing and evaluating manual tool tasks in the workplace. Such a prototype system, termed the data glove, was developed by overlaying twelve Force Sensitive Resistors on an posture-measuring glove (Cyberglove™, Virtual Technologies ...

The Seriously Uninjured Hand???Weakness of Grip
Journal of Occupational and Environmental Medicine, 1983Loss of grip is a rateable factor in the determination of permanent disability by compensation boards in some states. Malingerers, or those with psychological rather than organic disability, can voluntarily record lower grip measurements in the so-called injured hand when compared with the normal hand. The purpose here is to provide an objective method
