At Perm Polytechnic University (PNIPU), a new method has been developed for creating computing systems for sensor devices to operate in harsh environments. This was reported by the university's press service.
The new approach is based on using sound waves to determine the point of contact. It increases the accuracy, speed, and reliability of sensors.
The stages of creating our computing system include analyzing the conditions in which the touch screen will be used (indoors, outdoors, sea, desert), as well as the permissible size of the device, the required accuracy, and speed of operation. Based on this information, suitable materials that do not absorb sound waves are selected, and the speed of sound in them is calculated.
The main process of the sensor is to correctly locate the point of contact on the screen. In difficult conditions, the accuracy of localization may suffer, which reduces the efficiency of the device.
The scientists installed devices to register sound waves along the edges of the screen. This made it possible to achieve 100% accuracy.
Earlier, www1.ru reported that a unique sensor for detecting inert gases was created in Saratov.
