Abstract: A fluid reservoir and associated fluid circulation system and method are disclosed. The fluid reservoir is rotatable into any one of various rotational orientations and includes a housing defining an interior chamber that is divided into a working fluid chamber and a gas chamber by a membrane. An inlet port is fluidically coupled with the working fluid chamber to provide working fluid into the working fluid chamber and an outlet port is fluidically coupled with the working fluid chamber to remove working fluid from the working fluid chamber. A bleed channel extends a length along an outer periphery of the working fluid chamber and is fluidically open to the working fluid chamber along the length of the bleed channel. A bleed port is fluidically coupled with only a portion of the bleed channel and bleeds gas out of the working fluid chamber via the bleed channel.

Abstract: A system and method for dynamically controlling fluid pressure within a fluid flow circuit is disclosed. A fluid circulation system supplies working fluid through an inlet line and returns working fluid through an outlet line. A fluid management device is fluidically coupled to the inlet line and the outlet line. The fluid management device defines a pressure-controlled point. A first proportional valve and a first pressure sensor are disposed in the inlet line to selectively modulate and measure an inlet fluid pressure in the inlet line. A second proportional valve and a second pressure sensor are disposed in the outlet line to selectively modulate and measure an outlet fluid pressure in the outlet line. A controller is configured to maintain the inlet fluid pressure at a target inlet pressure and maintain the outlet fluid pressure at a target outlet pressure.

Abstract: An end effector for printing ink on a surface is disclosed. The end effector comprises a primary block comprises a primary-block body. A plurality of primary-printing modules are coupled to the primary-block body and translationally moveable, via a corresponding first actuator. Each one of the primary-printing modules includes at least one printhead which is adjustable, relative to the primary-block body. The printhead may be adjusted by at least one of a second actuator, configured to rotate the printhead about a first axis, or a third actuator, configured to rotate the printhead about a second axis. In some examples, a fourth actuator is configured to rotate at least one printhead, relative to at least one other printhead, about a third axis. Additionally, at least one trailing block can be coupled to the primary block so that the at least one trailing block is movable relative to the primary block.

Abstract: An end effector and associated systems and methods for printing ink on a surface is disclosed. The end effector comprises a main block including a back plate. The end effector also includes a plurality of slice assemblies slidably coupled to the back plate. Each one of the plurality of slice assemblies includes a printhead and a y-actuator. The y-actuator is selectively operable to extend and retract the printhead, parallel to a y-axis in first directions, and relative to the back plate. The end effector further includes a plurality of z-actuators coupled to the back plate. Each one of the plurality of z-actuators is selectively operable to extend and retract a corresponding one of the plurality of slice assemblies, parallel to a z-axis in second directions, which is perpendicular to the y-axis and relative to the back plate.

Abstract: A retention device comprising at least one main body member and one or more anchoring members. The main body member may comprise a plurality of retainer loops, which may traverse along a longitudinal axis of the main body member and may be adapted to retain one or more objects. The anchoring members may comprise at least a first anchoring member and a second anchoring member. The anchoring members may further comprise one or more shafts and one or more bases. The main body member may extend between the first anchoring member and the second anchoring member and may be removably coupled to the anchoring members. The plurality of retainer loops may be adapted to engage the shafts of the anchoring members. The bases of the anchoring members may be adapted to removably attach the anchoring members to a surface.

Abstract: A seal assembly can be incorporated into a track pin joint assembly including a pin defining a longitudinal axis, a first member and a second member both coaxial with the pin about the longitudinal axis. The first member is pivotable about the longitudinal axis with respect to the second member and includes a load ring engagement surface defining, at least in part, an axially-extending seal cavity disposed in proximal relationship to the second member. A seal assembly including a seal ring and a load ring is disposed in the seal cavity and sealingly engages the first member and the second member. The load ring includes a main body and a neck having a neck perimeter with a first sealing blade disposed along the neck perimeter and comprising an outwardly-extending projection. The first sealing blade is adapted to sealingly engage one of the seal ring and the first member.

Abstract: A trocar comprises a retention cannula comprising an inverted or incised retention pattern disposed thereon. Embodiments of the incised cannula exhibit reduced tissue trauma compared with screw-threaded cannula, improved fixation and/or retention compared with an unthreaded cannula, and good sealing between the cannula and the incision.
