Abstract Test card for color TV is a widely used method to evaluate the quality of a TV set directly. We have made a test signal generator (which can also generate synchronizing (abbreviated to sync hereafter) signals) mainly based on microprocessor Z-80. Taking the advantage of microprocessor programming, combining with the technique of microprocessor, digital circuits and analogue devices, we use software as far as possible to generate signals directly or to simplify the controlling circuits. Those signals, such as composite sync signal, bla ....etc

DISH STIRLING SYSTEMS
ABSTRACT
Electrical power generated with the heat from the sun, called solar thermal power, is produced with three types of concentrating solar systems - trough or linefocus systems; power towers in which a centrally-located thermal receiver is illuminated with a large field of sun-tracking heliostats; and dish/engine systems. A special case of the third type of system, a dish/Stirling system, is the subject of this paper. A dish/Stirling system comprises a parabolic dish concentrator, a thermal receiver, and a Stirlin ....etc

ABSTRACT
DISH TO DIGITAL: AMAZING GROWTH IN THE RADAR ANTENNA TECHNOLOGY
Radar is a vulnerable technology. Today’s military radar systems perform a variety of tasks which were not possible by the radar systems developed more than 6 decades ago during world war 2nd . There has been continuous efforts towards upgrading the radar system and associated technologies with drastic improvement in the performance. Almost every current radar innovation owes its existence to the advance ....etc

1.0 System Description
Dish/engine systems convert the thermal energy in solar radiation to mechanical energy and then to electrical energy
in much the same way that conventional power plants convert thermal energy from combustion of a fossil fuel to
electricity. As indicated in Figure 1, dish/engine systems use a mirror array to reflect and concentrate incoming direct
normal insolation to a receiver, in order to achieve the temperatures required to efficiently convert heat to work. This
requires that the dish tr ....etc

Abstract

The main scope of the project is to control the Dish antenna from a remote area.
Stepper motors operate differently from normal DC motors, which rotate when voltage is applied to their terminals. Stepper motors, on the other hand, effectively have multiple toothed electromagnets arranged around a central gear-shaped piece of iron. The electromagnets are energized by an external control circuit, such as a microcontroller.
To make the motor shaft turn, first one electromagnet is given power, which makes the gear's teeth ....etc
