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 _______.

Some people call it the Batcane.

These are reflected by objects which are near the blind person.

The larger the object, the larger the vibration.

The engineers who invented the cane are now planning new uses of echo-location to help the blind.

1 _______. Sensors in their homes can detect falls, lack of activity, or even if food is removed from the refrigerator. Lack of movement triggers an alarm which alerts medical staff or relatives. 2 _______. This can be sent via the telephone system to medical staff without the patient leaving home.
3 _______. The operation was carried out using a high-speed computer link and robotic tools in the French operating theatre. At this stage, such procedures are expensive and a local surgeon has to be present in case the network link fails. 4 _______.

Telecare is a way of looking after people such as old people at a distance.

Patients can wear monitors for recording the pulse and other signs.

Telesurgery was used in 2001 to allow a surgeon in New York to operate on a patient in France.

In the future, however, telesurgery could be a life-saver for people living, working, or travelling remote from medical help.
