Abstract: A surgical device for examination and treatment of a target area. The surgical device includes a shaft portion that extends along a longitudinal axis and that is configured to be inserted into a patient's body, a surgical tool provided within the outer sheath and configured to be movable along the longitudinal axis, and an optical assembly provided at a distal end of the inner shaft, the optical assembly including a light source and an imaging sensor.

Abstract: A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.

Abstract: A process for cold forging a metal fastener such as a self-clinching standoff includes a punch and die set at the final head trimming station which produces the shear burr only on the underside of the fastener head where it is not visible after installation. A knock-out pin which is reciprocal within the bore of the punch forcibly ejects the fastener through a passage in the die to a point beyond an opposite side of the die. A stripper sleeve which is reciprocal about the outside surface of the punch then moves from a retracted position over the end of the punch pushing a residual scrap ring from around the outside of the punch.

Abstract: A method of head trimming a fastener blank in a cold-forging process comprises placing a fastener blank into a bore of a punch having an end face; supporting an underside of a head portion of the fastener blank with the punch end face; moving a die having an internal passage and a trim plate with a cutting edge toward the fastener blank; shearing the head of the fastener blank with the cutting edge of the trim plate; stopping movement of the die at an extended trim position where the cutting edge lies beyond an underside of the head portion of the fastener blank; ejecting the fastener blank from the punch bore and through the die passage to an opposite side of the die; retracting the die; and removing a scrap ring from around the punch by a stripper sleeve.

Abstract: A method of assembling a captive panel fastener to a printed circuit board comprises the steps of placing an axially-extending shank of a captive fastener retainer through a mounting hole in a printed circuit board, soldering the retainer to the printed circuit board, cooling the retainer, and then affixing a retractable screw assembly including a plastic screw cap to the retainer by snap attachment of the screw cap to an outside surface of the retainer.
