SENSOR DEVICE WITH MEASUREMENT OF DYNAMIC IMPACT Russian patent published in 2015 - IPC G06F3/42 

FIELD: measurement equipment.

SUBSTANCE: invention relates to equipment of optical systems for sensor panels construction. The optical sensor device with measurement of dynamic impact comprises a sensor surface, a reflector, covering some perimeter of the sensor surface, the following components optically coupled with the reflector - a photodetector, a lens, two spatially distanced emitters, and also a calculator, besides, the output of the photodetector is connected to the input of the calculator, and the first and second emitters are connected to appropriate outputs of the calculator, additionally a cylindrical lens is added, optically coupled with the lens, and the photodetector is made as linear and installed in parallel to the sensor surface, besides, third and fourth emitters are added, which are optically coupled with the first and second emitters accordingly and are connected to additional outputs of the calculator, and the reflector is made in the form of the first and second segments separated by a non-reflecting gap, at the same time the calculating device determines dynamic impact of an operator's finger at the sensor panel, measuring the interval of time between appearance of the shadow on the first and second segments.

EFFECT: increased efficiency and accuracy of detection of coordinates of sensor surface touch, and also expansion of functional capabilities of a device by possibility of measurement of dynamic impact at a device sensor surface.
