10. Переведите предложения, учитывая особенности перевода инфинитивных оборотов (Приложение 2, табл. 10).

1. The importance of industrial robots is expected to increase very rapidly in the future.

2. Many robot related accidents have been reported to take place at different automated mills.

3. This task requires the worker to be near the robot.

4. The percentage of unrecorded robot accidents is presumed to be high.

5. The controller is assumed to store the trace of values corresponding to the most recent end-effector moves (движение). This trace is called event trace.

6. The experiments proved this system to be very efficient.

11. Прочитайте и переведите текст. Automatic supervisory systems

According to the classification of supervisory functions, three types of automatic supervisory systems may be distinguished: safety control, geometrical adaptive control and technological adaptive control. Safety systems deal with disturbances that lead to break-downs. Geometrical adaptive control systems supervise the quality of technological processes.

The typical structure of an elementary system of automatic supervision is as follows.

The quantity being measured is transformed by a sensor into a measurement signal: this is nearly always an electrical quantity. The signal is then pre-processed in order to improve signal-to-noise ratio.

The pre-processed signal undergoes the main processing in order to present it in a form which best represents the feature of the manufacturing system investigated. The processed signal is then evaluated from the point of view of the symptom of non-optimal functioning of the manufacturing system.

The symptom is sent to the supervising system. There, an appropriate command signal is formed according to the control strategy. This command signal is sent to the actuator and changes the controlled variable of the manufacturing system.

In the elementary system, only one parameter is known to be measured, and as a result of supervision only one control variable can be changed. In practice, more complicated systems are reported to be in use. They employ several sensors for the measurement and several control variables to influence the operation of the manufacturing system.
