Ultra Sonic Radar System

This project has many applications and many future expansions and functions that can be added on. By having a variable floating DC power supply, 7Hz-6 KHz function generator, and oscilloscope with leads connecting to any circuit built, the comprehensive hands-on learning tool would be ideal for most DeVry students.

complicated system. Over the next few pages I am going to try and go over the main parts of the

These products do not rebel against this issues but enhance the needed security that surrounds these controversies, thus these factors did not heavily affect Team 26’s product selection. Other factors that were considered, but did not measure up to our three vital requirements were usefulness, along with how often and how easy the usage of each product would be for the customer. Upon Team 26’s research and evaluations, the top three concepts for Digital Monitoring Products were: The Vision Door, The Portable Cell Tower, and the Weapon Finder. The preeminent concept that matched all requirements was between the Vision Door and the Portable Cell Tower.

By manipulating the key characteristics of the Schmitt trigger, it produces different frequencies fed to the speaker to operate. One key component of the Schmitt trigger is to determine the high and low thresholds at 3V. This is done with the help of the data sheet values as presented in the appendix below. The next section 3.2 contains a detailed explanation of the design process.

Pick an example of radar and explain how it works using at least one diagram or picture. [5 marks]

This is an integral part of transmission; because without power, transmission is impossible. It consists of the PHCN power supply, 250KVA Mikano generator and 150KVA Mikano

This radar is the primary system used for air and surface defense. “How SPY-1 works is that a mechanically rotating radar sends signals or beams outboard from the ship to pick up all targets” (Lockheed Martin). Once the radar receives return signals, the SPY-1 must use a different tracking radar by sending out signals of electromagnetic energy to track and determine what the target is as well as possible threat capabilities. Another reason why SPY-1 is the spear head for US Navy radar systems is its ability to track over one hundred targets at a time. “Some strengths of the SPY-1 that other radar do not have is it’s fast reaction and ability to detect and send a missile in less than ten seconds, fast transition from SPY-1 silent to full radiate, and its large field of fire with minimal blockage zones” (AN/SPY-1, 2000). The most important advantage of the SPY-1 is its ability to be linked with the Aegis system and how they work together to create one multi-functional defense system. SPY-1 is able to track targets while surveying the area as well as update the command and decision system used by Aegis to engage targets if

RADAR stands for RAdio, Detecting And Range, it main is used for the detecting objects by bouncing radio waves off of them and seeing how long it takes for the echo to return. It was developed by a number of nations secretly, but the term RADAR wasn’t used until 1940.

This home security system also has many other features. In case of a power loss, the alarm system will continue to work because it has a back up battery. This system can protect the most vulnerable areas of your home. The motion detectors provide an invisible blanket of protection over a wide area inside the home. The detectors can sense human body movement and heat and can immediately notify the ADT Home Security center. If you have not secured your home with high-end equipment, then give it a thought. It is worth trying for peace of mind and financial

Radar detectors work by notifying the driver after picking up radar waves coming from a speed detection device. Police use two methods to determine the speed of a vehicle, laser, and radar. Most police speed detectors

The building’s protection system included an automatic water sprinkler system, fire alarms, smoke control , heat

Ultrasound or other vibrations having an ultrasonic frequency, particularly as used in medical imaging. Ultrasound is a mechanical vibration of matter above the audible range. The wave is propagating through the medium as a

Echocardiography makes use of the properties of sound waves to identify tissues based on their densities. It differentiates tissue due to the fact that the speed of sound waves is dependent on the elastic properties and density of the medium it is travelling in, also known as the acoustic density of the tissue. The test uses ultrasound which have frequencies >20 KHz. Sound waves are generated by electrically stimulated piezoelectric crystal medium which then travels through an interface between tissues such as myocardium and blood. A

In next years, a lot of research is made in this field, to explore the more potential of piezoelectric effect. In labs scientists putted a lot of efforts to find out where and how they can use this piezoelectric effect. The first practical application of piezoelectric devices was used in First World War. A sonar device is used in this war which uses the piezoelectric effect. This discovery attracted other scientists to work in this field and develop more such devices which uses piezoelectric effect. In next few years, many new piezoelectric materials were explored and developed. Many applications were created that uses piezoelectric

The output of IC-2 is also used for lighting LED-1 indicating presence of signal. When no signal is available output of sensor module goes high and transistor LED is switched ‘OFF’. When another signal arrives, LED is switched ‘ON’ and through clock pulse at Pin No. 14 of IC-3. This makes the LED to switch ‘ON’ the appliance at first pulse and ‘OFF’ the appliance at its Second pulse arrived at its sensor. Transmitter circuits works satisfactorily with 6-9V DC. Battery but receiver circuits needs 6V regulated supply. The CAMD CM8870/70C provides full DTMF receiver capability by integrating both the band-split filter and digital decoder functions into a single 18-pin DIP, SOIC,or 20-pin PLCC package. The CM8870/70C is manufactured using state-of-the-art CMOS process technology for low power consumption (35mW, MAX) and precise data handling. The filter section uses a switched capacitor technique for both high and low group filters and dial tone rejection. The
