Abstract: A system for controlling a plurality of ophthalmic microsurgical instruments connected thereto. The microsurgical instruments are for use by a user such as a surgeon in performing ophthalmic surgical procedures. The system includes a data communications bus and a user interface connected to the data communications bus. The user interface provides information to the user and receives information from the user which is representative of operating parameters of the microsurgical instruments. The system also includes surgical modules connected to and controlling the microsurgical instruments as a function of at least one of the operating parameters. The surgical modules are also connected to the data communications bus. The data communications bus provides communication of data representative of the operating parameters between the user interface and the surgical modules.

Abstract: A pneumatic control system for providing pressurized air and vacuum to ophthalmic microsurgical instruments. The pneumatic system is constructed in a drawer assembly to allow it to be readily inserted into or removed from a modularly constructed cabinet of a microsurgical control console.In addition, the pneumatic system improves upon existing pneumatic control systems by providing a third mode of microscissors operation from a single pneumatic port. The third mode is made possible by a high speed three-way solenoid control valve which provides rapid pulses of air to the pneumatic port.A second improvement involves the use of a pneumatic pressure transducer to monitor pneumatic pressure being supplied to the pneumatic system in order to recognize non-hazardous transient drops in air pressure which can occur under certain normal operating conditions.

Abstract: A binding for athletic gear having a retaining device for a shoe which consists of a heel element and an instep element pivotally mounted with respect to each other by means of a coupling device. The heel element and the instep element can pivot into an open position in which the shoe can be inserted into the retaining device, then pivot into a closed position in which the heel element and the instep element are held by a locking device and in which the shoe is securely attached to the athletic gear.

Abstract: A system for controlling a plurality of ophthalmic microsurgical instruments is disclosed. Particularly, the present invention includes an ophthalmic handpiece, such as an intraocular surgical scissors or forceps, which is electrically isolated from the electric power source for controlling electrical hardware by a transformer. In a preferred embodiment, the handpiece is removably attachable to the electric control handpiece and is interchangeable with other ophthalmic handpieces. Furthermore, an apparatus to detect the presence of the interchangeable handpiece when it is connected to the controlling electric hardware is provided.

Abstract: A door frame and door assembly for installation in a man-door opening in a mine stopping in which the door is hinged for swinging movement on an axis extending transversely across the frame adjacent one face of the frame and adjacent the top of the frame. The hinge also mounts the door for up and down movement of the door relative to the frame. The door is of such height as to occupy a closed position in the frame inclined down from the hinge toward the other face of the frame with its lower edge bearing on the bottom of the frame and with the door at its top being engageable with and extending up past the top of the frame at the one face of the frame. The door is adapted to swing up from its closed position for opening it, and to move relative to the frame at the hinge to avoid jamming and buckling of the door while maintaining closure of the door upon distortion of the frame such as may result from pressure on the frame in a mine stopping.
