  • Publication number: 20240138812
    Abstract: An ultrasonic wave generation device including: an ultrasonic wave generation source; an ultrasonic wave condensation part; and a waveguide. The ultrasonic wave condensation part has a first reflection surface opposed to the ultrasonic wave generation source and a second reflection surface opposed to the first reflection surface. The first reflection surface reflects the ultrasonic wave, generated from the ultrasonic wave generation source, toward the second reflection surface. The second reflection surface reflects the ultrasonic wave, which has been reflected by the first reflection surface, toward the waveguide so as to introduce the ultrasonic wave into the waveguide. The waveguide protrudes from the first reflection surface to a side opposite the second reflection surface. A recessed portion is formed from the first reflection surface to the second reflection surface side along an outer circumferential surface of the waveguide.

  • Patent number: 9160902
    Abstract: An imaging apparatus is equipped with an analog block, an imaging condition determination section, and an analog gain control section. Current consumption of the analog block changes in accordance with an analog gain, which is an amplification ratio of outputs of an imaging device. The imaging condition determination section determines imaging conditions, including the analog gain, in accordance with the brightness of an imaging object. Depending on a state of the imaging apparatus, the analog gain control section alters the analog gain determined by the imaging condition determination section so as to reduce the current consumption of the analog block. Thus, in this imaging apparatus, the current consumption of the analog block may be reduced by the performance of control that alters the analog gain in accordance with the state of the imaging apparatus. Thus, the state of the imaging apparatus may be regulated.
