Patent ID: 6943511

Claim:
A motorized door/gate operator the improvement comprising; a logical means connected such that at least one input produces an open-output-signal and all other inputs disables the open-output-signal; a logical means connected such that at least one input produces a close-output-signal and all other inputs disables the close-output-signal; said open-output-signal connects to inverting means that disables the close logical means, thereby disabling the close-output-signal; an open-to-close delay circuit, arranged such that it delays the close-output-signal only after receiving the open-output-signal, otherwise, no significant open-output-signal delay is present; a close-to-open delay circuit, arranged such that it delays the open-output-signal only after receiving the close-output-signal, otherwise, no significant open-output-signal delay is present; a first switching means that reacts to the open-to-close delay output signal to supply power line voltage to a motor causing it to rotate in one direction; and a second switching means that reacts to the close-to-open delay output signal to apply power line voltage to the motor causing it to rotate in the opposite direction.
