This research aims at development of sensors for small size indoor mobile robots. We have proposed a new sonar-ring which can measure accurate direction and distance to reflecting points rapidly for this purpose. This new sonar-ring needs to receive echo signal by multiple receivers and to detect multiple Time-of-Flights (TOFs) in received signal at each receiver simultaneously for achieving fast and accurate measurement. However, it is impossible to satisfy them by conventional circuit. This paper proposes 30 channel 1 bit wave memory system to achieve these two points simultaneously and shows its usefulness.
