Iterative design of proximity sensor array for blind patient vehicle

The paper discusses a design process for proximity sensors that can be used to steer or guide the Blind Patient Vehicle (BPV) to obtain ultrasonic monitoring of nearby objects, leading to their recognition and localization. The objective of this paper was to develop an iterative engineering design process that can be used to produce inexpensive proximity measuring devices tailored to specific applications. The iterative engineering design process is based on state transition diagrams. Since one-level state transition diagrams can be quite complicated, we discuss how to simplify them by using multiple levels of abstraction. The resulting multi-level state diagrams are shown. We discuss how to use such multi-level diagrams to model iterative engineering design using the example of a proximity sensor array. In the summary, we characterize the obtained design results.ITERATIVE DESIGN OF A PROXIMITY SENSOR ARRAY FOR A BLIND PATIENT VEHICLE
The paper presents a design process for a proximity sensor array system that can be used to steer or guide a Blind Patient Vehicle (BPV) to obtain ultrasonic monitoring of nearby objects, leading to their recognition and localization.
The objective of this paper was to develop an iterative engineering design process that can be used to create an inexpensive proximity measurement system for specific applications. The iterative engineering design process was based on state transition diagrams. Single-level state transition diagrams can be too complicated, so the paper employs their simplification through the use of several levels of abstraction. The resulting multi-level state diagrams are presented. We discuss how to use such multi-level diagrams to model the iterative engineering design process, using the example of a proximity sensor array. In the summary, the obtained design results are characterized. (…)
