Look at the picture in your book and try to answer

the questions

The AbioCor Atificial heart

system

1. What kind of patient is the artificial heart for?

2. What does the artificial heart contain?

3. Why are there two batteries?

4. How is the internal battery charged?

5. What is the controller for?

The AbioCor is an artificial heart made of titanium and plastic. It is for the patients with very serious heart problems who are waiting for a heart transplant.It contains a hydraulic pump and a valve which lets the hydraulic fluid from one side of the heart to other. When the fluid moves to right, blood is pumped to the lungs. When the fluid moves to the left, blood is pumped to the rest of the body.The system has two batteries: one internal, inside the patient’s body, and one external. The internal battery lasts up to forty minutes. This is long enough for the patient to have a shower or to change the external battery. The external battery lasts four to five hours.The external battery provides power using a wireless energy transfer system. A coil on the patient’s skin induces power in a coil inside the body. This operates the controller and charges the internal battery.The controller contains a micro processor which decides the best heart rate for the patient at any time.

It’s my job

Before doing the activity in the book please do the activity given on the next slide. Your teacher’ll stop the recording after each paragraph for a short while

My a.special/ b. especial area is electronic a. assistive/ b. assertive technology, or EAT for short. I work for a company which makes a. equipment/ b. systems to help severely a. disabled/ b. abled people. I mean people who a. can/ b. can’t walk, people who have very limited movement – perhaps they can move only their a. head/ b. hand.

We make equipment which helps these people to live as a. independently/ b. dependently as a.possible/ b . impossible. By moving their a. chain/ b. chin, by blowing down a tube, or simply by speaking, they can a.send/b. receive an email, a.adjust/ b. control the temperature in the room, or a. operate/b. use a TV.

In this kind of work, you need a knowledge of a. mechatronics/ b. megatronics. That’s where mechanics, electronics, and software engineering a. meet/ b. greet. Take a page-turner, for example. It’s a device which turns the pages of a book or magazine. The a. input/ b. output can be a a. pneumatic/ b. air switch – that’s a switch worked by air pressure. You operate it by sucking or blowing down a tube. These signals are a. interpreted/ b. translated by a a. microprocessor/ b. microsissor which controls the mechanism which turns the pages. That mechanism uses electrical and mechanical devices. All three a. branches/ b. roots of engineering combine to make it work.

It’s an a.exciting/ b. boring job. Each a. development/ b. employment in technology means new possibilities for disabled people.

Blind people or people __________________often use a cane to feel their way when walking. The ultracane is a new type of cane ___________________________ ___________________It uses echo-location, like a bat, to detect objects around the blind person. Some people call it the Batcane. The cane transmits ultrasound signals. These reflected by objects Sensors on the cane receive the reflected signals which are passed to a microprocessor_______________ _____________________________ There are four buttons on the handle of the cane- the two ___________________ _________________are on the top, and the two which are for objects on the left and right on the back. These buttons vibrate when an object is detected. The larger the object, the larger the vibration.People _____________________say that with a little practice they can use these vibrations to make a mental map of their surroundings as they walk. Because cane uses vibrations, not noise, they can also use their ears for additional information about their surroundings. The engineers ___________________are now planning new uses of echo-location to help the blind.

A CT scanner essentially comprises of a table, a computer, and a gantry (the ‘donut’ shaped ring casing). Inside the gantry is an x-ray tube and a ring of radiation detectors which surround the table. During a CT scan, the x-ray tube spins around the patient emitting x-rays, which pass through the patient’s body. The amount of radiation absorbed by the patient is measured by the detectors. This information is then sent to a computer, which uses these measurements, the position of the patient and the angle the radiation was detected at, to decide whether each part of the patient scanned comprises of air, fluid, bone, fat, or muscle. This information is then displayed as a picture. In this way, a CT scanner enables a doctor to look at the body slice by slice.

Scottish scientists have developed a light-emitting, portable bandage that has been shown to fight skin cancer in a quicker, less painful way than conventional treatments. The metallic, adhesive bandage was created by physicist Ifor Samuel of the University of St. Andrews and dermatologist James Ferguson of Ninewells Hospital Dundee, and contains its own light source connected to a small, portable battery. The patch uses an organic diode that emits lights when a low-voltage electric current passes through it, and is portable enough that patients can move around during their daily treatment."It can be worn by the patient in a similar way to a sticking plaster (bandage), while the battery is carried like an iPod," Samuel said. The device builds on an existing conventional treatment method called photodynamic therapy treatment (PDT), which uses intense light to help a topical pharmaceutical cream be absorbed into the skin. Traditional PDT treatments tend to be painful and require patients to lie beneath a light for several hours. "This new device will have a major impact on the treatment of skin cancers," said Ferguson. "The light-emitting patch is a low-cost, portable and convenient method of treatment. Our initial pilot trials have already shown its effectiveness and we find patients requesting this treatment over conventional methods."

"If there are any idiots in the room, will they please stand up" said the sarcastic lecturer.

After a long silence, one freshman rose to his feet. "Now then mister, why do you consider yourself an idiot?" enquired the lecturer with a sneer.

"Well, actually I don't," said the student, "but I hate to see you standing up there all by yourself."
