1. INTRODUCTION
A heat pipe is a simple device that can quickly transfer heat from one point to another. They are often referred to as the superconductors of heat as they possess an extra ordinary heat transfer capacity & rate with almost no heat loss.
The development of the heat pipe originally started with Angier March Perkins who worked initially with the concept of the working fluid only in one phase (he took out a patent in 1839 on the hermetic tube boiler which works on this principle). Jacob Perkins (descendant ....etc

Thermoelectric coolers, also called thermoelectric modules or peltier coolers, are semiconductor-based electronic components that function as small heat pumps. On applying a low DC voltage to the thermoelectric module, heat moves through the module from one side to the other. One face of the module is therefore cooled, while the other face simultaneously heats up. This phenomenon may be reversed whereby a change in the polarity of the applied DC voltage will cause heat to be moved in the opposite direction. consequently, a thermoelectric module ....etc

4QD-TEC: Electronics Circuits Reference Archive Current Loop Interface



This circuit was developed to interface one of the new type contactless (inductive) throttle sensors to
4QD's motor controllers for use in a conversion to an Eze-Go golf car.

The throttle itself consists of a coil and some electronics with a steel jacketed brass slug which is moved
in and out of the coil by the throttle movement. The assembly has only two contacts and draws a current
of between 600 microamps ....etc

ABSTRACT:

In business a product could have a shorter life if it can't win the hearts of people and showcase new technology, so take the case of Nokia, who is coming up with the Nokia Morph flexible mobile phone which the company claims include nanotechnology and would immensely benefit its end-users. The main benefit of Nanotechnology is that its component ....etc

1. INTRODUCTION
Programmable logic controllers (PLCs) are members of the computer family capable of storing instructions to control functions such as sequencing, timing, and counting, which control a machine or a process. The PLC is composed of two basic sections, the Central Processing Unit (CPU) and the Input/Output (I/O) interface system. The PLC measures input signals coming from a machine and through the internal program provides output or control back to the machine.
Ladder logic is the programming language used t ....etc
