.... that of the French engineer and inventor Henri Giffard, who constructed in 1852 a cigar-shaped, non-rigid gas bag 44 m (143 ft) long, driven by a screw propeller rotated by a 2.2-kw (3-hp) steam engine. He flew over Paris at a speed of about 10 km/hr (about 6 mph). Giffard's airship could be steered only in calm or nearly calm weather. The first airship to demonstrate its ability to return to its starting place in a light wind was the La France, developed in 1884 by the French inventors Charles Renard and Arthur Krebs. It was driven by an electrically rotated propeller. The Brazilian aeronaut Alberto Santos-Dumont developed a ser .....

.... inputs enable the computer to generate an on screen image of the hand that follows the operator's hand movements. The glove also has miniature vibrators in the finger tips to provide feedback to the operator from grasped virtual objects. Therefore, driven by the proper software, the system allows the rator to interact by grabbing and moving a virtual object within a simulated room, while experiencing the "feel" of the object. The virtual reality line includes the Datasuit and the Eyephone. The Datasuit is an instrumented full-body garment that enables full-body interaction with a computer constructed virtual world. In one .....

The Phazer sends an invisible infared signals to the Lidar gun, this way the measurement of the speed is blocked. Many devices like that were outlawed because they transmit scrambling radar beams to the police car. The Phazer reflects only part of the signal and also mixes it with an FM signal. It is perfectly legal for people living in all states but California, Minnesota, Oklahoma, Virginia, and Washington D.C. The Phazer starts to scramble the signals from three miles awa .....

.... things that the so-called active medium might consist of are, atoms of a gas, molecules in a liquid, and ions in a crystal. Another component consists of some method of introducing energy into the active medium, such as a flash lamp for example. Another component is the pair of mirrors on either side of the active medium which consists of one that transmits some of the radiation that hits it. If the active component in the laser is a gas laser than each atom is characterized by a set of energy states, or energy levels, of which it may consist. An example of the energy states could be pictured as a unevenly spaced ladder which the .....

.... slid ruler was a mechanical device made of two rules, one sliding inside the other, and marked with many number scales. This slide ruler could do such calculations as division, multiplication, roots, and logarithms. Soon after came some more advanced computers. In 1642 came Blaise Pascal's computer, the Pascaline. It was considered to be the first automatic calculator. It consisted of gears and interlocking cogs. It was so that you entered the numbers with dials. It was originally made for his father, a tax collector.2 Then he went on to build 50 more of these Pascaline's, but clerks would not uses them.3 They did this in fear .....
