Abstract:
An apparatus for controllably moving an object between first and second locations comprising:a single input terminal adapted to receive a control signal that alternates between a first electrical state associated with said first location of said object, and a second electrical state associated with said second location of said object;a first electrically controlled positioner, coupled with said object and being operative, in response to a first electrical stimulus applied thereto, to move said object from said second location to said first location;a second electrically controlled positioner, coupled with said object and being operative, in response to a second electrical stimulus applied thereto, to move said object from said first location to said second location;a control circuit coupled to receive said control signal, and electrical energy for operating said first and second electrically controlled positioners, and having a first output from which said first electrical stimulus is applied to said first electrically controlled positioner, and a second output from which said second electrical stimulus is applied to said second electrically controlled positioner; andan electrical energy storage device coupled to said single input terminal and being operative to store said electrical energy from said first electrical state of said control signal.
