  • Patent number: 10983324
    Abstract: Provided is a light detecting apparatus including: a phase locked loop portion that generates a sampling clock based on a synchronization signal output from a light source that emits pulsed laser light; an A/D convertor that performs sampling of signal light output from a sample as a result of radiating the laser light thereon in accordance with the sampling clock; and a received-data processing portion that accommodates, every time N items of the sampling data are continuously acquired, the N items of data in a single data sequence. The phase locked loop portion is provided with a clock generating portion that generates a clock that has a frequency that is N times a pulse frequency of the laser light and that is synchronized with a phase of the laser light, and a delay adjusting portion that generates the sampling clock by adjusting a delay amount of the generated clock.

  • Publication number: 20210101455
    Abstract: A right side windshield is capable of changing a visible light transmittance of an upper part including an upper end, and a left side windshield is also capable of changing a visible light transmittance of an upper part. A light control switch is disposed on an instrument panel around a driver seat of a vehicle. The light control switch is operated to reduce the visible light transmittance of the upper part. The reduction in the transmittance can be performed simultaneously with the reduction in the visible light transmittance of an upper part of a front windshield.

  • Publication number: 20210101454
    Abstract: A light control system for a windshield can change a visible light transmittance of an upper part and a non-upper part of each of a front windshield, a right side windshield, and a left side windshield. A controller that controls a change includes a mode changing unit that changes a mode depending on whether a vehicle is not in a driving state or in a driving state. When the vehicle is not in a driving state, a change of reducing the visible light transmittance of the upper part and the non-upper part to be lower than a predetermined value is permitted. When the vehicle is in a driving state, a change of reducing the visible light transmittance of the upper part to be lower than the predetermined value is permitted and a change of reducing the visible light transmittance of the non-upper part to be lower than the predetermined value is prohibited.
