Abstract: A surgical instrument includes a body, a shaft assembly extending distally from and rotatably coupled to the body, an end effector extending distally from the shaft assembly, a fiber optic cable, and a rotary coupling assembly. The end effector may rotate with the shaft assembly relative to the body. The end effector includes a sensor assembly. The fiber optic cable extends proximally from the sensor assembly, along the shaft assembly, and into the body. The fiber optic cable includes a distal portion that rotates with the end effector, a proximal portion associated with the body, and a coiled portion interposed between the distal portion and the proximal portion. The rotary coupling assembly includes a handle-side body and a shaft-side body. The rotary coupling assembly can radially expand and contract the coiled portion of the fiber optic cable in response to relative rotation between the handle-side body and the shaft-side body.

Abstract: A surgical system includes a surgical instrument, including a shaft assembly having a distal end and an end effector at the distal end of the shaft assembly. The end effector includes a first jaw, a second jaw movably coupled relative to the first jaw for clamping tissue therebetween, and an optical sensor for detecting the tissue. The surgical system also includes a generator configured to supply a therapeutic energy to the first jaw or the second jaw, and a pass-through device configured to be connected between the surgical instrument and the generator. The pass-through device includes a therapeutic energy connector configured to operatively couple the generator to the surgical instrument for transmitting the therapeutic energy from the generator to the first jaw or the second jaw, and at least one optical component configured to transmit light to the optical sensor and to receive light from the optical sensor.

Abstract: An airfoil includes a first airfoil piece and a second airfoil piece that is bonded to the first airfoil piece at a joint. The first airfoil piece and the second airfoil piece are formed of aluminum alloys. At least one of the aluminum alloys is an aluminum alloy composition that has greater than 0.8% by weight of zinc. The joint includes a braze element of magnesium, zinc, or combinations thereof in a higher concentration than in other portions of the first airfoil piece and the second airfoil piece.

Abstract: An illustrative embodiment of a computer-implemented method for correlating artifacts between a versioned domain and an un-versioned domain, generates metadata having attributes of both of the versioned domain and the un-versioned domains, for an artifact in a set of artifacts; creates an instance using a specific version of a versioned artifact definition, wherein the instance comprises a first part directly created from the versioned artifact definition and a second part created from an un-versioned artifact definition; specifies linkages between a respective representation of the artifact in the versioned domain and the un-versioned domain; provides a set of facades through which a selected one of author, execute and update instances of the artifact is performed using either the versioned domain or the un-versioned domain; and correlates all versions of the artifact definition to a single un-versioned definition.

Abstract: Mechanisms are provided for monitoring an area utilizing an unmanned vehicle. These mechanisms identify an area to be monitored by an unmanned vehicle and identify an unmanned vehicle assigned to monitoring the identified area. The mechanisms further generate, for the unmanned vehicle, a travel path to be traversed by the unmanned vehicle using a function to randomize generation of the travel path. Moreover, the mechanisms program the unmanned vehicle to traverse the generated travel path and initiate operation of the unmanned vehicle to collect data about the area while traversing the generated travel path. In addition, the mechanisms monitor the area utilizing the unmanned vehicle based on the data collected by the unmanned vehicle while traversing the generated travel path.
