15. What is modulation? Give its advantages. Answer Definition of Modulation The message signal having weak strength cannot be transmitted directly through the communication channel Since carrier signal carries the message signal therefore, certain carrier signal parameters are changed according to the message signal. A method in which message signal is transmitted to the receiver with the help of carrier signal is called modulation. In this, both carrier signal and message signal are combined…

Jude Medical have vulnerabilities that let the hacker access a device. The devices, such as defibrillators and pacemakers are used to control heart functions and prevent heart attacks. The penetrable devices under FDA’s warning are the Merlin@home Transmitters made by St. Jude Medical, which are the part of the home monitor. Pacemakers and other implanted cardiac devices use a wireless RF signal to connect to the home monitor. A physician can monitor the pacemaker and patients’ health by…

Equality is agreeably something the world should be pursuing, but should we have total equality? Should everyone be the same in order for it to be fair? Kurt Vonnegut’s short story, “Harrison Bergeron” describes a world where there is total equality; everyone is the same. The story takes place in 2081, where amendments have been added to make everyone the same. Those who are stronger, faster, smarter or beautiful wear burdens to bring them down to the same level as the rest of society. No one…

1762-IF4 is an Allen Bradley MicroLogix 1200 System with 4 Channel Current/Voltage Analog Input Module. It has a dimension of 90 x 87 x 40.4 mm. It has Delta-Sigma converter and 4 differential (bipolar) inputs. It’s analog operating voltage range is -10 – 10 V DC normal and -10.5 – 10.5 V DC full scale. It’s analog operating current range is 4 – 20 mA normal and -21 – 21 mA full scale. It converts the analog input up to the full-scale range. It enhances the functionality of MicroLogix 1200…

in aviation long before his father’s death. The Hughes family was known for their engineering background; and growing up Hughes Jr. would take things apart and put them back together. Before the age of twelve, Hughes built Houston’s first radio transmitter and a motorized bicycle. And by the age of fourteen, Hughes started taking flying lessons. One day Hughes Sr. and Jr. were at a Harvard-Yale boat race. Hughes Sr. promised Jr. anything he would like if Harvard won the race. Harvard did win, so…

Introduction As homeotherms, humans have the ability to control thermoregulatory mechanisms: physiological processes that are critical to maintaining core temperature within a very narrow limit. Although peripheral temperature fluctuates regularly & often largely in response to ambient temperature, core temperature must be maintained within a tight window in order for the human body to function properly. Throughout the course of circadian rhythm, the body’s core temperature can fluctuate by up…

involve a complex surgery in the head to the ear. They will implant an electrode array behind the ear and attached a line to a stimulator just above the ear. The individual will then place the transmitter, which is magnified on top of the head, over the stimulator, which is also magnetic. Connected to the transmitter is a speech processor/microphone behind the ear that picks up the sound. Because the person is deaf and because of the cochlear implant sound is not heard within the ear. The sound…

her heart. The heart rate monitor consist of two parts they work together. The transmitter which looks like a belt and needs to be fixed around the chest and the receiver will be worn as a watch on the wrist. They have different functions, the monitor will measure and record your average heart rate from the moment the monitor is switched on till it is been turned off. Important is the direct contact from the transmitter to the skin, as it picks up electrical signals from the heart through the…

Scottish-born American inventor and teacher of the deaf, Alexander Graham Bell (1847-1922) is best known for perfecting the telephone to transmit vocal messages by electricity. The telephone inaugurated a new age in communication technology. Alexander Graham Bell was born on March 3, 1847, in Edinburgh. His father, Alexander Melville Bell, was an expert in vocal physiology and elocution; his grandfather, Alexander Bell, was an elocution professor. After studying at the University of Edinburgh…

Harrison Bergeron versus 2081 We hold these truths to be self-evident: that all men are created equal; that they are endowed by their Creator with certain unalienable rights; that among these are life, liberty, and the pursuit of happiness. Thomas Jefferson. We in the United State hold this line of the Declaration of Independence to be a pivotal part of our country. We have went to war many times to uphold the right that everyone to be equal. Many men and women have died to help ensure that…
