Patent number: 11914082Abstract: A ranging device includes transducers, a transmission circuit, a reception circuit, a transfer data generation circuit, and a transfer circuit. The transmission circuit causes the transducers to transmit transmission waves. The reception circuit outputs a received signal obtained by digitizing a reflected wave of the transmission wave with a sampling frequency equal to or more than a frequency of the transmission wave. The generation circuit separates, into a target period and a non-target period, time-series received signals. The target period is a period in which a wave height is equal to or more than a threshold. The non-target period is a period in which a wave height is less than the threshold. The generation circuit performs thinning-out processing on received signals in the non-target period and generates waveform information indicating a waveform received by the transducer. The transfer circuit outputs the waveform information.Type: GrantFiled: November 22, 2022Date of Patent: February 27, 2024Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Takuya Iwamoto, Tadashi Morita
