WIPO Patent Application WO/2022/195330

A1

Today, the prevalence of dangerous viruses in the world has increased, such as the coronavirus, which has created many problems for people in all walks of life. This new disease is a contagious disease of touching objects that the virus stays on objects for hours to days. Therefore, when using public services such as elevators, ATMs, etc., the virus may be transmitted to the body. For this reason, we designed an invention that does not need to press the keys of the devices, and it is enough to point out the existing holes. To use the light beam and without touching any part of the desired activity. This design consists of several major parts that this product has finally been achieved. The plan generally consists of several main parts, which are: The first part of the internal panel with several keys: transparent perforated panel, transmitter, receiver, optical filters, input holes, display, audio circuit, microcontroller circuit, light intensity comparator circuit. The second part of the external panel with a key: transparent perforated panel, transmitter, receiver, optical filters, inlet holes, 83 kHz modulation, sensor Tripod, circuit box. This design can be used for a variety of elevator key panels, hospital and bank queuing keys, keys used to enter doors, etc.
