1 _______.
One product of bioengineering is the artificial heart, which can extend and improve the lives of patients who might die of heart failure while waiting for a transplant of a natural heart. 2 _______. It has electric motors and a pumping system with hydraulic fluid and hydraulic valves. It has external and internal parts (i.e. outside and inside the body). 3 _______. This internal battery is recharged by an external battery using a simple electrical coil, which induces a current. This current then recharges the internal battery. The whole system is controlled by a microprocessor inside the body. Of course, biological safety is very important, so the plastics used in the valves and hydraulic membranes of the artificial heart are durable enough to withstand 100,000 beats of the ‘heart’ per day. 4 _______.

A patented charging technology for all kinds of batteries shortens battery charge times, generates no heat while charging, and extends the battery life 10-fold, to as many as 5,000 charge and discharge cycles. With nickel-cadmium (Ni-Cd) batteries, the charging time drops 90 per cent or more. The system will charge batteries up to 110 per cent of their manufacturer-rated (nominal) capacities, and restores memory-impaired batteries to 98 per cent of their former capacities. The system is easier on batteries than slow- and fast-charging methods, with over-charge and over-heat batteries by force-feeding current. Using a custom IC, the battery chargers read the electrochemical potential of a battery under charge, and determines its internal condition. They change the flow of current during millisecond-scale periods.

Blind people or people who cannot see well often use a cane to feel their way when walking. The Ultracane is a new type of cane which helps blind people to avoid obstacles in their part. It uses echo-location, like a bat, to detect objects around the blind person. 1 _______. The cane transmits ultrasound signals. 2 _______. Sensors on the cane receive the reflected signals which are passed to a microprocessor which calculates the position and size of the object.
There are four buttons on the handle of the cane – the two which are for objects in front and overhead are on the top, and the two which are for objects on the left and right are on the back. These buttons vibrate when an object is detected. 3 _______.
People who have tried the cane say that with a little practice they can use these vibrations to make a mental map of their surroundings as they walk. Because the cane uses vibrations, not noise, they can also use their ears for additional information about their surroundings. 4 _______.

1_____________________________________. They in the 1950s and ’60s discovered the fun they could have experimenting with the school’s computer, which was available at night. 2_________________________________. They developed a counterculture. 3_____________________________________.
Hacking began to seem more sinister in 1988, when Robert T. Morris, a 23-year-old computer science graduate student at Cornell, created a “virus” - a destructive computer program - that spread through network and erased vital information in military and academic computers. 4____________________________________.
