A Java Ring is a finger ring that contains a small microprocessor with built-in capabilities for the user, a sort of smart card that is wearable on a finger. Sun Microsystem s Java Ring was introduced at their JavaOne Conference in 1998 and, instead of a gemstone, contained an inexpensive microprocessor in a stainless-steel iButton running a Java virtual machine and preloaded with applets (little application programs). The rings were built by Dallas Semiconductor.
Workstations at the conference had ring readers installed on them that download ....etc

ABSTRACT

This paper presents an anthropomorphic robot hand called the Gifu hand II, which has a thumb and four fingers, all the joints of which are driven by servomotors built into the fingers and the palm. The thumb has four joints with four-degrees-of-freedom (DOF); the other fingers have four joints with 3-DOF; and two axes of the joints near the palm cross orthogonally at one point, as is the case in the human hand. The Gifu hand II can be equipped with six-axes force sensor at each fingertip and a developed distributed tactile sensor w ....etc

1. Introduction

The nature of the public network has changed. Demand for Internet Protocol (IP) data is growing at a compound annual rate of between 100% and 800%1, while voice demand remains stable. What was once a predominantly circuit switched network handling mainly circuit switched voice traffic has become a circuit-switched network handling mainly IP data. Because the nature of the traffic is not well matched to the underlying technology, this network is proving very costly to scale. User spending has not increased proportionally to t ....etc

INTRODUCTION



The new systems include a weapon, head-to-toe individual protection, onboard computer network, and enhanced human performance.
The Future Warrior will be a responsive and formidable member of an invincible battle space team.



TECHNOLOGY

The key technology supporting these initiatives is ad hoc peer-to-peer wireless networking (ad hoc p2p), also known as a mobile mesh network.
Ad hoc p2p operates by taking a collection of mobile terminals (such as ....etc
