Abstract: A remote control unit for use with an ophthalmic surgical system having a main control console with video display screen and operator interface. The remote controller is connected by an electrical umbilical cord to the main console and provides a second operator display and membrane-switch interface for use by a surgeon or other member of the surgical team. This remote control unit has its own housing with a splash-resistant front face that is divided into primary and secondary operator interface panels. The primary panel includes a rectangular display field having a plurality of back-illumination lights for selectively illuminating legends found on a replaceable legend card that fits within a slot behind the face plates. Control functions corresponding to the illuminated legends may be selected or de-selected by pressing nearby switches arranged in locations adjacent to the display field. The secondary panel also contains membrane switches and legends illuminated by back-lighting.

Abstract: A motorized IV pole system for controlling the height of an IV container to thereby control the infusion pressure in an IV tube includes a telescoping IV pole system. In one embodiment, comprising three concentric support members, the outer support member is fixed, the middle support member is reciprocable with respect to the outer support member and is driven by a rack gear attached thereto. An inner support member is reciprocatable in the interior of the middle support member and is driven by a cable attached to the outer support member passing over a pulley attached to the middle support member. The rack on the middle support member may be driven by a shaft to which is attached a hand crank and an AC motor. The AC motor may be driven by a programmable control system which includes an optical encoder to permit display of the height of the IV container. Also, preselected heights and various speeds of height adjustment may be utilized.

Abstract: A scoring tool for forming a scoreline having a predetermined depth in a composite container label layer is disclosed, including an annular scoring blade and a holder assembly supporting the blade for rotation about an axis. The holder assembly includes a blade holder member having an annular portion at one end upon which the blade is mounted, the outer diameter of the annular portion corresponding with the inner diameter of the scoring blade. The blade holder member also has at its other end a flange portion the outer diameter of which is less than that of the blade member. The holder includes an annular locking member for retaining the scoring blade in contiguous relation with the flange portion. The locking member is mounted concentrically about the holder member annular portion, the outer diameter of the locking member being less than that of the flange portion.
