Abstract: A surgical system may include tiered-access features. The surgical system may be used to analyze at least a portion of a surgical field. Based on a control parameter, the system may scale up or down various capabilities, such as visualization processing, endocutter communication, endocutter algorithm updates, smart cartridge connectivity, smart motor control for circular stapler, smart energy control, cloud analytics, hub connectivity control, and/or hub visualization and control interactions. The control parameter may include system aspects such as processing capability or bandwidth for example and/or the identification of an appropriate service tier.

Abstract: A surgical instrument controls communication capabilities between the surgical instrument and a removeable component. The surgical instrument may determine parameters associated with the surgical instrument and the removable component. Based on the parameters, the surgical instrument determines a level or tier of communication between the surgical instrument and the removable component. The surgical instrument may determine to configure one or more of the following levels: one-way static communication with the component; two-way communication with the component; real-time two-way communication with the component; and communication with a surgical hub.

Abstract: An apparatus is configured for use with a switchgear assembly having a frame that defines at least one switchgear cell, stationary disconnects oriented vertically on the frame, and horizontal draw-out disconnects remote from the frame. In a given example, the apparatus includes an adapter assembly including vertical disconnects, horizontal disconnects, and bus work connecting the vertical disconnects with the horizontal disconnects. The adapter assembly is configured to take an installed position in the switchgear cell, with the vertical disconnects in the adapter assembly projecting upward into engagement with the stationary disconnects on the frame. The adapter assembly is further configured for the horizontal disconnects in the adapter assembly to engage and disengage from the horizontal draw-out disconnects upon movement of the horizontal draw-out disconnects horizontally into and out of engagement with the adapter assembly when the adapter assembly is in the installed position.

Abstract: A sectional ski composed of a forward and a rear section which interlock forward of the boot supporting region of the ski. The sections, preferably made of fiberglass, have male and female coupling members composed of aluminum or other lightweight but strong metal, molded as an integral part of the respective sections. The front coupling member, serving as the rear portion of the front section, consists of a recessed area which also houses a pair of eccentrically mounted cams. These cams engage and disengage the interlocking surfaces of cam slots in both sides of the male lock insert which serves as the front portion of the rear section of the ski. As the two sections are slidably engaged, the cams draw the coupling members together laterally and lock them into an integral unit.

Abstract: Oil resistant modified organopolysiloxane compositions are prepared by polymerizing an acrylic ester and an acrylic nitrile in the presence of an organopolysiloxane and a free-radical initiator at an elevated temperature. These modified compositions may be thermally cyclized to impart improved oil resistance to these already oil resistant compositions. The resultant compositions may be cured to form oil resistant silicone elastomers.

Abstract: In combination with a fluid applicator of the fluid marker type, a unitary, self-sealing, one-way check valve for admission and retention of air under pressure to the interior of the applicator, an elastomeric bulb for developing pressure and means for relieving internal pressure.
