Abstract: Apparatus and method for surgical repair of a detached retina includes an array of insulated electrodes that can be positioned adjacent the rear of an eye near the detachment site for selective excitation of pairs of the electrodes to selectively develop electrostatic attractive force on the retina that is detached from the rear of the eye. The array of electrodes may be selectively deployed and retrieved from the distal end of the cannula which can be positioned near the detachment site to facilitate orientation and control of the electrostatic force. Plural electrodes in multiple sets may be selectively activated in order to reposition of the electrostatic force without substantially altering the position of the array near the rear of the eye. A controllable power supply may include manual and foot-actuated controls for switching multiple sets of electrodes and altering the magnitude of the electrostatic force developed at the operational site.

Abstract: An apparatus and process are provided for the production of plywood. The apparatus is adapted to form plywood panels without prior patching of defects in the veneer sheets used to form the panel. The formed panel then is electro-optically scanned to identify and locate defects. The sensed defect data is stored in a control unit which in turn directs a defect removal apparatus and a patcher to appropriate locations for removing and patching the defects.
