5. Look through text 2 once again and say whether the following sentences are true (t) or false (f):

1) The data in the radio-frequency tags will include not only the ‘best before’ date but also nutritional data.

2) You can order food with the help of Screenfridge.

3) The Screenfridge is equipped with a microphone, speaker, video-camera and a telephone.

4) You can keep an eye on the children when you are out if you have a Screenfridge.

6. Read text 3 and name the function of electronic nose. Text 3. Electronic nose

An electronic nose is a device intended to detect odors or flavors. The expression "electronic sensing" refers to the capability of reproducing human senses using sensor arrays and pattern recognition systems. The stages of the recognition process are similar to human olfaction and are performed for identification, comparison, quantification and other applications, including data storage and retrieval.

In all industries, odor assessment is usually performed by human sensory analysis, by chemosensors, or by gas chromatography. The latter technique gives information about volatile organic compounds but the correlation between analytical results and actual odor perception is not direct due to potential interactions between several odorous components.

The electronic nose was developed in order to mimic human olfaction that functions as a non-separative mechanism: i.e. an odor / flavor is perceived as a global fingerprint. Essentially the instrument consists of head space sampling, sensor array, and pattern recognition modules, to generate signal pattern that are used for characterizing odors. Electronic noses include three major parts: a sample delivery system, a detection system, a computing system.

7. Look at the text once again and answer the questions:

1) What does the expression “electronic sensing” refer to? 2) What is the disadvantage of the odor assessment performed by gas chromatography? 3) What parts do electronic noses consist of?

8. Read text 4 and say what robotically-assisted surgery was developed for. Text 4. Robotic surgery

Robotic surgery, computer-assisted surgery, and robotically-assisted surgery are terms for technological developments that use robotic systems to aid in surgical procedures. Robotically-assisted surgery was developed to overcome the limitations of minimally-invasive surgery and to enhance the capabilities of surgeons performing open surgery.

In the case of robotically-assisted minimally-invasive surgery, instead of directly moving the instruments, the surgeon uses one of five methods to control the instruments; either a direct telemanipulator or through computer control. A telemanipulator is a remote manipulator that allows the surgeon to perform the normal movements associated with the surgery. In computer-controlled systems the surgeon uses a computer to control the robotic arms and its end-effectors, though these systems can also still use telemanipulators for their input. One advantage of using the computerized method is that the surgeon does not have to be present, but can be anywhere in the world, leading to the possibility for remote surgery.
