DIGITAL MULTI-COMPONENT MOTION SENSOR Russian patent published in 2013 - IPC G01B21/32 

FIELD: measurement equipment.

SUBSTANCE: digital multi-component motion sensor comprising a body, a recording unit, a sensitive element with motion sensors, connected into an electric circuit, differing by the fact that the elastic body of the sensor is made in the form of a monoblock from a composite material by winding of a tape of a thermoplastic material with further polymerisation of layers, with placement of deformation strain sensors in its layers, current-conducting elements and contact groups, mounted in layers of the body, the above monoblock of the body has the following structure of the layers differing according to performed functions within the body, counting from outside to inside, a protective layer, which protects elements of the sensor against environmental impact, a layer that levels thickness, comprising holes and grooves for protruding parts of the next layer, an instrumental layer comprising strain sensors, current-conducting elements and contact groups, a support layer that perceives load during writing of a handwritten text, an element of transfer of axial pressure of the writing unit is made in the form of a hollow rod with a writing unit installed in it and connected by the end with the sensitive element, made in the form of an elastic membrane jammed in the in the sensor's body, besides, the element of transfer of the axial movement of the writing unit is made in the form of a ball, contacting with a piezoelement, such as a piezoelement of direct effect of movements, besides, the axis of sensitivity of the piezoelement matches with the longitudinal axis of the sensor.

EFFECT: expansion of functional capabilities of a device due to selective measurement of static or smoothly changing movements along all directions of space with their subsequent digitisation, in particular, development of a small-size device in the form of a pen; rating of the movement of the writing unit during writing of a handwritten text for subsequent statistic treatment; obtaining higher reliability, since in solid multi-layer body the sensors are protected against unfavourable conditions of environment, besides, during manufacturing of the body an excessive quantity of sensors may be installed in its layers, which, whenever necessary, may be readjusted.
