A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable coupling stent, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the coupling stent attached thereto. The coupling stent may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes a hollow two-piece handle through which a balloon catheter passes. A valve holder is stored with the heart valve and the handle easily attaches thereto to improve valve preparation steps.

A weather resistant sound attenuating communications headset of modular construction includes two ear cup modules, a microphone boom module, a head band module, a headband cable module, and a termination cable module. The modular construction allows easy replacement of modules as well as selected components of the modules under field conditions without the need for tools. Replaceable water resistant thin film membranes are employed to provide weather protection as well as hygienic protection for the microphone, speaker and amplification electronics. The thin film membranes which cover areas which come into intimate contact with the wearer are easily replaceable under field conditions. Thus a headset that is shared by more than one user can be hygienically cleansed by simple replacement of the microphone and ear cup membranes.

A shelving glide includes a deck having a plurality of dividers; a first trough having a first index arranged along at least a portion of a width of the deck; a second trough having a second index arranged along at least a portion of the width of the deck; and a plurality of partitions defining a plurality of pathways. A partition includes a first clip securable to the first index; and a second clip securable to the second index. The partition is adjustable along the width of the deck from a first position to a second position upon disengagement of the second clip from the second index. The first clip is adapted to disengage from the first index upon disengagement of the second clip from the second index. The partition is secured to the deck at the second position upon reengagement of the second clip to the second index.

A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the frame attached thereto. The frame may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes an integrated handle shaft and balloon catheter. A valve holder is stored with the heart valve and the handle shaft easily attaches thereto to improve valve preparation steps.

A mop assembly including a mop head and handle, and a supply of liquid connected to a valve assembly on the handle adjacent the mop head. The valve assembly includes a length of resiliently flexible tubing that has a portion extending transversely through the handle and first and second members on opposite sides of the length of tubing that are relatively movable between a closed position at which the first and second members pinch together opposite sides of the length of tubing to stop the flow of liquid through it, and an open position at which the first and second members are spaced apart to afford flow of liquid through it. Should the tubing become plugged, it can easily be replaced by disconnecting one end from a liquid supply length of tubing, withdrawing the tubing from between the first and second members, and then installing a new length of tubing. A storage cart for use with the mop assembly includes an elongate upwardly projecting main portion having walls providing a side surface, and an elongate tray portion that provides a receptacle adapted to receive the mop head. The tray portion is mounted on a bottom end of the main portion for relative movement between a closed position at which the side surface covers an open side of the receptacle to thereby afford retention of the mop head in the receptacle; and an open position with the tray portion disposed at about a right angle with respect to the main portion so that the mop head can be inserted into or removed from the receptacle and so that the bottom wall can be supported along a horizontal surface such as a floor surface with side walls of the receptacle projecting upwardly.

An ornamental design of a make-up brush with a replaceable brush head includes a handle portion having an elongated central axis and a snap fastener. A first portion of the snap fastener is fastened to the handle portion and a second portion of the snap fastener is fastened to a replaceable head. A third portion of the snap fastener includes a push button aligned with the snap fastener along an elongated central axis, wherein the decorative make-up brush is symmetrical. The replaceable head and handle portion are wobble free secured.

A modular, scalable, extensible, In-Flight Entertainment (IFE) data communication system is described. In one embodiment, a server/switch line replaceable unit including at least one server, at least one switching element and a plurality of fiber optic transceivers communicates with a plurality of passenger seat video display units over fiber optic cables. A server, such as, for example, an audio server, a video server, an audio/video server, a game server, an application server, a file server, etc, provides data (e.g., entertainment programming, internet file data, etc.) to the video display unit. In one embodiment, a hybrid switch unit provides flexible communication between one or more servers and the passenger seats.

A passenger seat is with a seat back breakover assembly for preventing movement of the seat back unit forwardly past an upright position during normal use and for permitting forward movement of the seat back past an upright position in response to a predetermined abnormal load applied in a forward direction. The breakover assembly includes a controlled deformation member having a bend in one end thereof and positioned intermediate one a section assembly module of the seat and the seat back unit. The bend of the deformation member captures therein an attachment member fixed to and movable forwardly and rearwardly in unison with the seat back unit. An end of the deformation member remote from the bend is restrained for restricted and controlled movement relative to the section assembly module. The deformation member has a resistance to deformation in response to a normal forwardly-applied force sufficient to prevent forward movement of the seat back unit beyond the upright position. The deformation member is deformable in response to an abnormal forwardly-applied force along its length whereby the bend in the deformation member is translated rearwardly along the length of the deformation member to thereby dissipate the abnormal force without damage to the seat back unit.

The invention provides a control system and method of an artificial intelligence drive robot. The system comprises a receiving module, an artificial intelligence module, a central processing unit, a cloud processing module and an executing module. The method comprises the steps that scene information of the surrounding and voice and/or visual information of a user are acquired; a comprehensive decision is made after recognition and understanding according to voice and/or visual information; the intention of the user is confirmed, and the robot gives a response; and a treatment result is outputin multiple modes including one or more of moving of the intelligent robot, action of a mechanical arm and/or a head, expression video image display on a screen, and audio playing. According to the method, artificial intelligence analysis and decision can be carried out locally or through cloud uploading according to acquired voice and/or visual information, the robot is automatically controlledto be in interactive feedback with the user in multiple manners, much hardware can be arranged outside, a designer quickly expands a machine body, and an artificial intelligence result can be intuitively and effectively achieved on the robot.
