Abstract: Systems, methods and devices for the automated delivery of goods form one to another using a robotic tug and accompanying cart. A computer within the tug or cart stores an electronic map of the building floor plan and intended paths for the tug to take when traversing from one location to the next. During the delivery, a variety of different sensors and scanners gather data that is used to avoid obstacles and/or adjust the movement of the tug in order to more closely follow the intended path. The system preferably includes both wired and wireless networks that allow one or more tugs to communicate with a tug base station, a primary network located at the site of the delivery and a remote host center that monitors the status and data collected by the tugs.

Abstract: An enclosure system for receiving a cable includes an enclosure having an inner chamber and an open position exposing the inner chamber and a closed position covering the inner chamber. A cable receiving port in a wall of the enclosure extends along a longitudinal axis from outside of the enclosure into the inner chamber. The cable receiving port is configured to receive a cable therein when the cable is advanced axially into the port without rotation of the cable when the enclosure is in the closed position. A mating member is associated with the cable receiving port that limits rotation of the cable when the cable is advanced axially into the port. An axial retention member is associated with the cable receiving port that limits axial movement of the cable out of the port when the cable is advanced axially into the port to a lock position.

Abstract: Aspects of the present disclosure relate to a fiber management structure including a splice tray. The splice tray includes a front side and a back side. The fiber management structure includes a first attachment module that mounts by a location-selectable connection to the splice tray at a selected mounting location. The selected mounting location being one of a plurality of different mounting locations at which the first attachment module can be mounted to the splice tray. The first attachment module includes a fiber containment wall that projects upwardly from the front side of the splice tray when the first attachment module is mounted to the splice tray.

Abstract: A ball injector for connecting below the frac head of a frac tree to accommodate and sequentially drop a ball into the axial passageway of the frac tree. The ball injector has an axial passage of an injector housing aligned with the axial passageway of the frac tree. A ball cartridge assembly stores one or more balls and sequentially delivers one ball to a port in the ball cartridge assembly. A ball launch side arm extends from the injector housing and forms a ball launch passageway communicating between the ball cartridge port and the axial passage. A first valve member in the ball launch passageway is opened to pass the ball into the axial passage, and is closed to isolate the ball cartridge assembly from a pressure in the axial passage. A second valve member between the first valve member and the ball cartridge assembly may be included to form a pressure isolation chamber between the valve members. Embodiments of ball cartridge assemblies to horizontally store a plurality of balls is provided.

Abstract: A modular acetabular cup assembly for use with multiple bearing liners is disclosed. The acetabular cup assembly includes a shell having a tapered inner wall and two circumferential grooves. The shell may be used with polyethylene, ceramic, metal, and other types of liners.

Abstract: A collar for axially positioning a vortex-induced vibration (VIV) suppression device along a tubular is disclosed. The collar has an annular body portion and a plurality of support members extending in a radial direction from the annular body portion. The support members are annularly spaced around the annular body portion such that gaps are formed between the support members, the gaps being dimensioned to receive an auxiliary tubular positioned external to a main tubular around which the annular body portion is positioned.

Abstract: A device 10 for repairing mitral valve leaflets 2, 3 includes a jaw mechanism 15 that may be positioned adjacent a mitral valve leaflet 2, 3. The jaw mechanism 15 may move between an open position and a closed position by pivoting a first jaw relative 16 to a second jaw 18. The first jaw 16 may include a rivet 28 that may move from a stored position to an application position projecting away from the first jaw 16 when the jaw mechanism 15 is moved from the closed to the open position. Closing the jaws 16, 18 about a valve leaflet 2, 3 causes the rivet 28 to pierce the leaflet. The jaw mechanism 15 may then be rotated to wind the leaflet 2, 3 thereabout and again pierce the leaflet. The rivet 28 may then be released from the jaw mechanism 25 and the device 10 removed from the patient.

Abstract: A fairing for suppressing a vortex induced vibration (VIV) of a tubular. The fairing including a tail member dimensioned to suppress a vortex induced vibration of a tubular. The fairing further including an encircling member dimensioned to encircle less than an entire circumference of a tubular, the encircling member being separable from the tail member. The fairing further including a connecting assembly dimensioned to attach the tail member to the encircling member.

Abstract: The present disclosure relates to a tool for attaching a line having pre-coated hot melt adhesive to a structure.
