Abstract: An apparatus and method for registering and deskewing a sheet along a sheet path. A pair of drive spheres are located in the sheet path. When a sheet enters the nips formed by the spheres the sheet is driven until it is sensed by a sensor. The drive spheres are driven by a pair of wheels which allow the spheres to rotate about any axis through their center and parallel to the plane of the sheet. The spheres are driven such that the sheet is side registered and deskewed as it is moved along the sheet path. Constant feedback from the sensors to the drive controller allows the sheet to be registered in a very short distance and has the added benefit of self compensation for wear of the drive components. The wide registration and deskewing latitude of the device allows for the use of relatively inexpensive and low accuracy sheet drives preceding the device.

Abstract: An electrometer (20) for measuring an unknown DC potential finds particular utility in applications requiring a high input resistance and minimal current drain during measurement. The electrometer (20) employs a circuit containing a sampling diode (D1) and capacitor (C1). Prior to a measurement being taken, the capacitor (C1) is charged to a common-mode voltage and the diode (D1) is reverse biased to a potential approximating the unknown potential of the voltage source (30) to be measured. A switch (S1) is employed to momentarily cause current flow through the capacitor (C1) and to forward bias the diode (D1). The unknown potential is calculated from potentials associated with the sampling diode (D1) and the capacitor (C1). The calculation involves sampling the potential of the capacitor (C1) at precisely determined time delays.

The system includes an operating environment having an application control module (ACM) that is run-time bound and executable by the applications. The ACM furnishes generalized procedural codes for each application. The application uses data structures to define the appearance and operation of the application to the ACM. The system also integrates the application program interfaces (API's) of an operating environment graphic user interface (GUI) system and a database management system (DBMS) within the ACM. The invention reduces the programming required for applications and improves consistency in programming across multiple applications.

Abstract: A surgical implant for securing ligament grafts into a joint. The implant has back-biting threads that allow the implant to be advanced into bone by impaction. If necessary, the implant can be removed from the bone by rotation. The implant is used, for example, for knee ligament repair by forming a longitudinal socket in a bone. The socket is intersected by a transverse pin. A flexible strand is drawn with the pin through the bone. A looped portion of the flexible strand is diverted so as to protrude out of the entrance to the longitudinal socket. The ends of the flexible strand remain accessible on either side of the bone. The ligament graft is captured within the strand loop protruding from the entrance to the socket. The strand is retracted into the socket, drawing the graft into the socket by pulling on the accessible ends of the flexible strand. The graft is fixed in the socket using the transverse implant.
