| Summary: | The System for Identifying Silent Objects for Persons with Blindness on Public Roads is a system designed to identify and inform the blind about objects that endanger them on public roads such as trees, poles, trenches and bars. To inform the object identified in front of the user as well as the status of the system being worn, this system has a special interface located on the user's arm. In building this interface, a switching design, a DC-DC Converter 7.2 V to 100 V, and a battery indicator with each connection with other subsystems are needed. This document discusses the design, implementation and results of testing of the three parts of the System for Identifying Silent Objects for Persons with Blindness on Public Roads. The test results show that the switching design can provide electrical sensation in a 5x5 matrix representation. The performance of DC-DC Converter fulfills system requirements by amplifying the 7.2 V input voltage to the value of 101.3 V. The accuracy of the battery indicator has an error of 0.4%. The three parts that are worked on can meet the overall system requirements. |
