  • Publication number: 20240175941
    Abstract: An electric circuit abnormality detection device includes a pulse generator, a directional coupler, and a detection unit. The detection unit includes a reference reflected wave database and a calculation part. The reference reflected wave database stores waveform information of a reference reflected wave inputted from the directional coupler when a pulse signal is inputted to a reference electric circuit that has a same wiring pattern as a pulse heater and does not have an abnormality. The calculation part detects an abnormality in the pulse heater by comparing waveform information of a reflected wave inputted from the directional coupler when the pulse signal is inputted to the pulse heater, with waveform information of the reference reflected wave stored in the reference reflected wave database.

  • Publication number: 20240157397
    Abstract: An acoustic element integrated circuit includes cells, being arrayed two-dimensionally on a same curved surface, wherein capacitive acoustic-elements having vibration membranes are allocated by unit number in each of the cells. Each of the cells encompasses an intra-cell circuit, which includes an exciting circuit for driving collectively portions by the unit number, the portions having transmitting functions of the acoustic-elements, and a reception circuit for processing collectively received signals transferred from portions by the unit number, the portions having reception functions in the acoustic-elements. Here, the exciting circuits are sorted into a chip in which high-voltage drivers for exciting the vibration membranes are merged and a chip in which circuits operated at voltages lower than the high-voltage drivers are merged, and the cells are operated two-dimensionally, by individually controlling the intra-cell circuits so that cells can be driven independently.
