FIELD: input devices.
SUBSTANCE: invention relates to the field of input devices. Disclosed is a wireless stylus for an environmentally isolated device for input and display of information based on electromagnetic resonance, comprising a housing having a front housing and a rear housing, an opening in the front of the housing, a tip located in the front of the housing that is positioned to pass through the opening, and with the ability to move the tip along the axis of the body, having the front part of the tip protruding from the hole outside the body for contact with the protective glass of the device, and the rear part of the tip, located in the rear part of the housing, an oscillatory circuit tuned to resonance with the inductive sensor unit of the input and display device, and containing at least a capacitor and an inductor with a ferrite core divided into two parts, one of which is made stationary, and the second is located with the ability to move along the axis of the body relative to the first part of the core, insulating means for isolating the oscillatory circuit from the environment, located with the possibility of interaction with the rear part of the tip during mechanical action on the front part of the tip for transferring mechanical action from the tip to the moving part of the ferrite core of the inductor with relative displacement of the moving part of the core relative to the fixed part to change the resonant frequency of the oscillating circuit.
EFFECT: providing a wireless stylus for an environmentally isolated input and display device based on electromagnetic resonance.
