DEVICE FOR FORMING CONTROL COMMANDS FOR CONTROLLING TWO-POSITIONAL OBJECTS Russian patent published in 2005 - IPC

FIELD: electronics.

SUBSTANCE: device includes use of key object only having one switching contact, non-moveable contacts of which are combined, in circuits for forming coordinates. Output signals form at moment of change of position of any key and are connected to coordinate circuits by separator diodes. For same coordinates of address of controlled object outputs of diodes connected to different keys are combined and connected to memory registers and to assembly for determining presence and duration of formed impulse signal. In case of errors detection command is ignored, as well as fact of error detection. Used assemblies for forming and control as well as use in transfer of command of straight and inverse codes provides for high trustworthiness of control commands.

EFFECT: higher trustworthiness.
