Abstract: A lens assembly includes a lens barrel, a plurality of lenses arranged inside the lens barrel along an optical axis, and a cover member fixed to an end of the lens barrel on a subject side and fixing a last lens of the plurality of lenses on the subject side, wherein outer diameters of the plurality of lenses decrease from the subject side to an image side, and an outer diameter of the lens barrel is constant or smaller from the subject side to the image side.

Abstract: The present invention relates to an ambulance having an infectious disease blocking function and an interior pressure control method therefor, the ambulance having a driver seat, a vehicle body and an emergency care compartment which is mounted on the vehicle body and which has a space in which a patient can be placed, and comprising an air pressure regulation part for setting the inside of the emergency care compartment to have a positive pressure or a negative pressure, and a control part for selectively controlling a positive pressure or a negative pressure of the air pressure regulation part.

Abstract: Disclosed are a multi pickup coil for wireless charging of an electric vehicle such as an electric bus or an electric passenger car and industrial equipment while stopping or driving, and a pickup apparatus having the multi pickup coil. The multi pickup coil and the pickup apparatus provide high-capacity and high-efficiency wireless charging per unit area by performing performance enhancement through an optimal design in order to overcome the limitations of a circular pickup coil.

Abstract: A wireless charging power supply system during operation of electric vehicles and industrial equipment while operating is described. The withstand voltage problem on the power supply line was solved by the capacitor provided in the inverter, and the power supply line and common line arrangement. This makes it possible to extend the wireless power supply line and the economical problem of the wireless charging system is greatly improved. In the prior art, compatibility was maintained with various wireless charging pick-up pads installed in the vehicle by using a plurality of inverters. In this system, compatibility is satisfied at a lower cost by utilizing the relay present in the inverter. The EMI of the power supply line is reduced by maximizing the magnetic field cancellation effect by using the structure of the common line and the shielding tube.
