  • Patent number: 11598848
    Abstract: Aspects of the disclosure provide a system and method used for time-of-flight lidar applications. Such systems and methods include a laser and pulse clipper which produces a shuttering effect to reduce the instantaneous output power from the pulse clipper. Accordingly the output from the pulse clipper is more suitable for time-of-flight lidar applications than that initially produced by the laser. This can allow for lasers which may otherwise exceed eye safety limits to be used for time-of-flight lidar applications without exceeding the eye safety limits.

  • Patent number: 11591764
    Abstract: A system provides impressed current cathodic protection (ICCP) of a marine structure (50) and powers a load in a load arrangement (100) arranged on the marine structure (50) and in contact with the water (10). The power source provides a supply current to generate an electrical potential of the marine structure. The load arrangement (100) has an electrode arranged (130) to extend from the load arrangement into the water for transferring the supply current via the water. The load (20) is coupled between the electrode (130) and a power node (120). The power source is connected to the marine structure and to the power node. The load arrangement is arranged to use the supply current to provide power to the load. Thereto the supply voltage may have an AC component at a high frequency. The load may be an UV-C LED for emitting anti-fouling light.
