Introduction
One new emerging new technology that will have an impact in today’s society is Li-Fi or light fidelity. Li-Fi is a wireless communication through light something very similar to Wi-Fi except Wi-Fi uses wireless bandwidth signals to send information compare to Li-Fi uses the light system in most building to send information so you are able to connect your devices to the internet. Li-Fi is beneficial to society in a way that it can be more efficient in terms of security, energy, and eliminates health concerns. Just imagine if every street light is equip with Li-Fi then the internet access will be limitless and would need to rely on cell towers for internet and it can help relieve the stress the it can cause on some networks.
Li-Fi is categorized as a Visual Light Communication. Visual Light Communication is a light source that can send information but the light must be visible in order to be considered Visual Light Communication. Originally Visual Light was achieve with sunlight but now that the fact the LEDs Lights are becoming more common Visual Light Communication is easier to achieve then before.
Historical Timeline
Photo of Alexander Graham Bell
The concept of Visible Light Communication or VLC for short has been around for over a hundred years now. It started in the 1880’s with a man name Alexander Graham Bell who was experimenting to see if there was a possibility to send information through light. He experimented on the though and what he was able to accomplish was the photophone. The photophone was the very first instance of Visible Light Communication. Alexander Graham Bell was able to transmit and audio sounds through a beam of light in this case sunlight.
Photo on how the Photophone works
The next instance of Visible Light Communication is more recent. In 2003 at Nakagawa Laboratory in Japan, they decide to use LED’s instead of sunlight. Because of theresearch, it led to a more attention to Visible Light Communication that allowed many projects to take off such as D-Light Project, COWA, and more. These projects are moving along much better now because LED’s lights are starting to become more common and edging out the old incandescent and fluorescent lights bulbs. On top of that, they last much longer and more energy efficient and cost is starting to come down on them.
Graph of different bulbs being compared
In 2010, a company called Siemens use the progress already made with Visual Light Communication and expanded on it wi.
The health dangers of Wi-Fi Radiation
Wireless routers – as well as Bluetooth and similar wireless systems – give off electromagnetic radiation in the low-igahertz frequency.This level is considered potentially dangerous to people. And the danger is
compounded by several factors:
Just like the wireless signals themselves, the EMFs can pass through walls.
Most routers are not turned off at night, so you are exposed 24/7.
You are not only exposed to EMFs from your own router. Did you ever search for a wireless signal and see not only your wireless network, but also your neighbor’s and the one from the business down the street? All of them emit EMFs.
Scientists and researchers are uncovering the health risks of EMFs. Depending on the level and the length of exposure,
Those risks can range from insomnia and headaches to tumors.
Li fi technology
Li-fi is a new wireless technology that uses visible light communication through LED light bulbs to transmit data. It can provide wireless connections up to 224 gigabits per second, much faster than traditional Wi-Fi. Li-fi works by varying the intensity of LED lights to transmit binary code and is received through photodetectors. It has advantages over Wi-fi like better security since light cannot pass through walls and higher speeds. Potential applications include smart lighting, medical uses, aviation, education and home/office networks. Li-fi faces challenges from light interference and inability to transmit through solid objects. Overall, li-fi could replace Wi-fi hotspots and enable a cleaner, safer and more efficient wireless future.
Light fidelity or li fi
This document discusses Li-Fi, also known as light fidelity. It is a technology that uses visible light communication (VLC) to transmit data wirelessly using LED light bulbs. Some key points:
- Li-Fi provides wireless internet access at speeds faster than 10 Mbps by transmitting data through light waves instead of radio waves.
- A prototype was able to stream high quality video using a standard LED lamp in 2011.
- Li-Fi has advantages over Wi-Fi such as higher speeds up to 500 Mbps, more available spectrum, better security since light cannot pass through walls easily.
- Potential applications include underwater communications, internet access anywhere there is light like street lamps, and use in

between the onset of ‘P’wave and onset of ‘Q’ wave.
•‘P-R’ interval cause atrial depolarization and conduction of impulses through AV node.
Duration:0.18 (0.12 to 0.2) sec
Q-T Interval:
•‘Q-T’ interval is the interval between the onset of ‘Q’
wave and the end of ‘T’ wave.
•‘Q-T’ interval indicates the ventricular depolarization
and ventricular repolarization,
i.e. it signifies the
electrical activity in ventricles.

Introduction
One new emerging new technology that will have an impact in today’s society is Li-Fi or light fidelity. Li-Fi is a wireless communication through light something very similar to Wi-Fi except Wi-Fi uses wireless bandwidth signals to send information compare to Li-Fi uses the light system in most building to send information so you are able to connect your devices to the internet. Li-Fi is beneficial to society in a way that it can be more efficient in terms of security, energy, and eliminates health concerns. Just imagine if every street light is equip with Li-Fi then the internet access will be limitless and would need to rely on cell towers for internet and it can help relieve the stress the it can cause on some networks.
Li-Fi is categorized as a Visual Light Communication. Visual Light Communication is a light source that can send information but the light must be visible in order to be considered Visual Light Communication. Originally Visual Light was achieve with sunlight but now that the fact the LEDs Lights are becoming more common Visual Light Communication is easier to achieve then before.
Historical Timeline
Photo of Alexander Graham Bell
The concept of Visible Light Communication or VLC for short has been around for over a hundred years now. It started in the 1880’s with a man name Alexander Graham Bell who was experimenting to see if there was a possibility to send information through light. He experimented on the though and what he was able to accomplish was the photophone. The photophone was the very first instance of Visible Light Communication. Alexander Graham Bell was able to transmit and audio sounds through a beam of light in this case sunlight.
Photo on how the Photophone works
The next instance of Visible Light Communication is more recent. In 2003 at Nakagawa Laboratory in Japan, they decide to use LED’s instead of sunlight. Because of theresearch, it led to a more attention to Visible Light Communication that allowed many projects to take off such as D-Light Project, COWA, and more. These projects are moving along much better now because LED’s lights are starting to become more common and edging out the old incandescent and fluorescent lights bulbs. On top of that, they last much longer and more energy efficient and cost is starting to come down on them.
Graph of different bulbs being compared
In 2010, a company called Siemens use the progress already made with Visual Light Communication and expanded on it wi.
The health dangers of Wi-Fi Radiation
Wireless routers – as well as Bluetooth and similar wireless systems – give off electromagnetic radiation in the low-igahertz frequency.This level is considered potentially dangerous to people. And the danger is
compounded by several factors:
Just like the wireless signals themselves, the EMFs can pass through walls.
Most routers are not turned off at night, so you are exposed 24/7.
You are not only exposed to EMFs from your own router. Did you ever search for a wireless signal and see not only your wireless network, but also your neighbor’s and the one from the business down the street? All of them emit EMFs.
Scientists and researchers are uncovering the health risks of EMFs. Depending on the level and the length of exposure,
Those risks can range from insomnia and headaches to tumors.
Li fi technology
Li-fi is a new wireless technology that uses visible light communication through LED light bulbs to transmit data. It can provide wireless connections up to 224 gigabits per second, much faster than traditional Wi-Fi. Li-fi works by varying the intensity of LED lights to transmit binary code and is received through photodetectors. It has advantages over Wi-fi like better security since light cannot pass through walls and higher speeds. Potential applications include smart lighting, medical uses, aviation, education and home/office networks. Li-fi faces challenges from light interference and inability to transmit through solid objects. Overall, li-fi could replace Wi-fi hotspots and enable a cleaner, safer and more efficient wireless future.
Light fidelity or li fi
This document discusses Li-Fi, also known as light fidelity. It is a technology that uses visible light communication (VLC) to transmit data wirelessly using LED light bulbs. Some key points:
- Li-Fi provides wireless internet access at speeds faster than 10 Mbps by transmitting data through light waves instead of radio waves.
- A prototype was able to stream high quality video using a standard LED lamp in 2011.
- Li-Fi has advantages over Wi-Fi such as higher speeds up to 500 Mbps, more available spectrum, better security since light cannot pass through walls easily.
- Potential applications include underwater communications, internet access anywhere there is light like street lamps, and use in

CONDUCTION SYSTEM OF THE HEART
ECG:
●ECG is a graphic record of the electrical activity of the heart.
●Electrical activity precedes the mechanical activity of the heart.
●Electrical activity has two phases:
Depolarization- contraction of muscle
Repolarization- relaxation of muscle
ECG Leads:
●6 Chest leads
●6 Limb leads
1. Bipolar Limb Leads:
Lead 1- Between right arm(-ve) and left arm(+ve)
Lead 2- Between right arm(-ve) and left leg(+ve)
Lead 3- Between left arm(-ve)
and left leg(+ve)
2. Augmented unipolar Limb Leads:
AvR- Right arm
AvL- Left arm
AvF- Left leg
3.Chest Leads:
V1 : Over 4th intercostal
space near right sternal margin
V2: Over 4th intercostal space near left sternal margin
V3:In between V2 and V4
V4:Over left 5th intercostal space on the mid
clavicular line
V5:Over left 5th intercostal space on the anterior
axillary line
V6:Over left 5th intercostal space on the mid
axillary line.
Normal ECG:
Waves of ECG:
P Wave
•P Wave is a positive wave and the first wave in ECG.
•It is also called as atrial complex.
Cause: Atrial depolarisation
Duration: 0.1 sec
QRS Complex:
•QRS’ complex is also called the initial ventricular complex.
•‘Q’ wave is a small negative wave. It is continued as the tall ‘R’ wave, which is a positive wave.
‘R’ wave is followed by a small negative wave, the ‘S’ wave.
Cause:Ventricular depolarization and atrial repolarization
Duration: 0.08- 0.10 sec
T Wave:
•‘T’ wave is the final ventricular complex and is a positive wave.
Cause:Ventricular repolarization Duration: 0.2 sec
Intervals and Segments of ECG:
P-R Interval:
•‘P-R’ interval is the interval
between the onset of ‘P’wave and onset of ‘Q’ wave.
•‘P-R’ interval cause atrial depolarization and conduction of impulses through AV node.
Duration:0.18 (0.12 to 0.2) sec
Q-T Interval:
•‘Q-T’ interval is the interval between the onset of ‘Q’
wave and the end of ‘T’ wave.
•‘Q-T’ interval indicates the ventricular depolarization
and ventricular repolarization,
i.e. it signifies the
electrical activity in ventricles.
Duration:0.4-0.42sec
S-T Segment:
•‘S-T’ segment is the time interval between the end of ‘S’ wave and the onset of ‘T’ wave.
Duration: 0.08 sec
R-R Interval:
•‘R-R’ interval is the time interval between two consecutive ‘R’ waves.
•It signifies the duration of one cardiac cycle.

prepared by Prof. BLESSY THOMAS, SPN
Empyema is a disease of respiratory system It is defines as the accumulation of thick, purulent fluid within the pleural space, often with fibrin development.
Empyema is also called pyothorax or purulent pleuritis.
It’s a condition in which pus gathers in the area between the lungs and the inner surface of the chest wall. This area is known as the pleural space.
Pus is a fluid that’s filled with immune cells, dead cells, and bacteria.
Pus in the pleural space can’t be coughed out. Instead, it needs to be drained by a needle or surgery.
Empyema usually develops after pneumonia, which is an infection of the lung tissue. it is mainly caused due in infectious micro-organisms. It can be treated with medications and other measures.

Introduction:
Welcome to our captivating SlideShare presentation on the Special Senses, where we delve into the extraordinary capabilities that allow us to perceive and interact with the world around us. Join us on a sensory journey as we explore the intricate structures and functions of sight, sound, smell, taste, and balance.
The special senses are our primary means of experiencing and interpreting the environment, each sense providing unique and vital information that shapes our perceptions and responses. These senses are facilitated by highly specialized organs and complex neural pathways, enabling us to see a vibrant sunset, hear a symphony, savor a delicious meal, detect a fragrant flower, and maintain our equilibrium.
In this presentation, we will:
Visual System (Sight): Dive into the anatomy and physiology of the eye, exploring how light is converted into electrical signals and processed by the brain to create the images we see. Understand common vision disorders and the mechanisms behind corrective measures like glasses and contact lenses.
Auditory System (Hearing): Examine the structures of the ear and the process of sound wave transduction, from the outer ear to the cochlea and auditory nerve. Learn about hearing loss, auditory processing, and the advances in hearing aid technology.
Olfactory System (Smell): Discover the olfactory receptors and pathways that enable the detection of thousands of different odors. Explore the connection between smell and memory and the impact of olfactory disorders on quality of life.
Gustatory System (Taste): Uncover the taste buds and the five basic tastes – sweet, salty, sour, bitter, and umami. Delve into the interplay between taste and smell and the factors influencing our food preferences and eating habits.
Vestibular System (Balance): Investigate the inner ear structures responsible for balance and spatial orientation. Understand how the vestibular system helps maintain posture and coordination, and explore common vestibular disorders and their effects.
Through engaging visuals, interactive diagrams, and insightful explanations, we aim to illuminate the complexities of the special senses and their profound impact on our daily lives. Whether you're a student, educator, or simply curious about how we perceive the world, this presentation will provide valuable insights into the remarkable capabilities of the human sensory system.

FACIAL NERVE
The facial nerve, also known as cranial nerve VII, is one of the 12 cranial nerves originating from the brain. It's a mixed nerve, meaning it contains both sensory and motor fibres, and it plays a crucial role in controlling various facial muscles, as well as conveying sensory information from the taste buds on the anterior two-thirds of the tongue.
