13.8 Closedloop dynamic systems are often difficult to analyze and test. Special test facilities are often constructed for this purpose. Diagram such a test setup for evaluating an unmanned air vehicle (UAV) designed for remote surveillance using an optical sensor. Assume that the test equipment includes an actual optical sensor, while other system components are simulated. Indicate which elements in the simulation are part of the system under test and which elements represent external inputs. Label all blocks and input/output lines. One system engineering responsibility of advanced development is to understand how the system concept will accept, transform, consume, and produce each of the four functional elements of signals, data, materials, and energy. To illustrate this concept, for Problems 13.9 through 13.12, evaluate how you would engineer a system that would automate lawn care, such as monitoring lawn water levels to determine when to start/stop automated sprinklers; how to determine when an automated lawn mower should service the lawn; what displays and commands should be provided to the user. For each problem, construct a table with four columns, labeled Accept, Transform, Consume, and Produce.

13.9 In the Accept column, describe what signals will the system accept from all external entities. In the Transform column, describe the transformation of these signals, and what the system will transform these signals into. In the Consume column, describe what signals the system will consume and for what purpose. Note that the system will either transform or consume all of its input signals. In the Produce column, describe what signals the system will produce for output.

13.10 In the Accept column, describe what data the system will accept from all external entities. In the Transform column, describe the transformation of these data, and what the system will transform these data into. In the Consume column, describe what data the system will consume and for what purpose. Note that the system will either transform or consume all of its input data. In the Produce column, describe what data the system will produce for output.

13.11 In the Accept column, describe what materials the system will accept from all external entities. In the Transform column, describe the transformation of these materials, and what the system will transform these materials into. In the Consume column, describe what materials the system will consume and for what purpose. Note that the system will either transform or consume all of its input materials. In the Produce column, describe what materials the system will produce for output.

13.12 In the Accept column, describe what energy the system will accept from all external entities. In the Transform column, describe the transformation of these energies, and what the system will transform these energies into. In the Consume column, describe what energies the system will consume and for what purpose. Note that the system will either transform or consume all of its input energy. In the Produce column, describe what energies the system will produce for output. Remember that energy may take several forms.
