  • Publication number: 20140331833
    Abstract: Woodworking machines including conductive cutters adapted to cut workpieces, and motors adapted to drive the cutters are disclosed. The machines also include a contact detection system adapted to detect contact between a person and the cutter, and to distinguish contact between the person and the cutter from contact between the workpiece and the cutter. The machines further include a reaction system adapted to cause a predetermined action to take place upon detection of contact between the person and the cutter by the contact detection system.

  • Patent number: 8840628
    Abstract: The invention is directed to mainpulator assembly (2) for holding and manipulating a surgical instrument (14) in a telerobotic system. The assembly comprises a base (6) fixable by passive or power driven positioning devices to a surface, such as an operating table, and an instrument holder (4) movably mounted on the base. The instrument holder comprises a chassis (6) and an instrument support (70) movably mounted on the body and having an interface engageable with the surgical instrument to releasably mount the instrument to the instrument holder. A drive assembly (7) is operatively coupled to the instrument holder for providing the instrument with at least two degrees of freedom. The instrument holder is separable from the base and the drive assembly so that the holder can be sterilized. The assembly further includes a force sensing element (52) mounted distal to the holder and the drive assembly for detecting forces exerted on the surgical instrument and providing feedback to the surgeon.

  • Patent number: 8371196
    Abstract: A method of controlling a woodworking machine having a movable cutting tool. The method monitors a signal for a change indicative of a dangerous condition between the cutting tool and a person, senses movement of the cutting tool, and performs an action to mitigate the dangerous condition when the signal change and movement of the cutting tool are both detected. A woodworking machine including a detection system adapted to detect a dangerous condition between a person and a working portion of the machine and then to perform some action to mitigate the dangerous condition is also disclosed. A motion detection system is adapted to detect motion of the working portion and to disable the reaction system when the working portion is not moving.

  • Publication number: 20110295315
    Abstract: The invention is directed to a system and method for releasably holding a surgical instrument (14), such as an endoscopic instrument configured for delivery through a small percutaneous penetration in a patient. The instrument comprises an elongate shaft (100) with a pair of mounting pins (116) laterally extending from the shaft between its proximal and distal ends. An instrument holder comprises a support having a central bore (202) and an axially extending slot (204) for receiving the instrument shaft and the mounting pins. A pair of locking slots (206) are cut into the support transversely to and in communication with the axial slot so that the mounting pins can be rotated within the locking slots. The instrument support further includes a latch assembly for automatically locking the mounting pins within the locking slots to releasably couple the instrument to the instrument holder.
